2 WORM GEAR JACK MODES WORM GEAR WORM GEAR SCREW JACK TECHNICA INTRODUCTION ACTIONJAC JACKS ActionJac Worm Gear Screw Jack systems are ruggedly designed and produced in standard models with load handling capacities from / ton to 00 tons. They may be used individually or in multiple arrangements. There are no standard travel lengths and each Worm Gear Screw Jack is built to specification. MACHINE SCREW JACK The worm gear driven Machine Screw Jack incorporates an alloy steel worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent loss of lubrication (sealed radial bearings on the / and ton units). The drive sleeve is supported on antifriction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the acme thread lifting screw to translate or rotate, depending upon jack configuration. The jack housing is made of ductile iron (MJ models have aluminum housings, aluminum optional on one ton models) and proportioned to support the rated capacity of the unit. The lifting screw is made of alloy steel with a minimum tensile strength of 9,000 psi. The threads are precision formed, typically using Class -C (Centralizing) tolerances. Jack lift shaft lead tolerance is approximately 0.00" per foot. BA SCREW JACK The ActionJac Ball Screw Jacks use the same worm gear set arrangement as machine screw jacks. The addition of a high efficiency ball screw and nut reduces the required input torque to approximately one-third the torque required for the Machine Screw Jack. The Ball Screw Jack housing is made of ductile iron (/ BSJ and / H-BSJ jacks have aluminum housings, aluminum optional on one ton models) and designed to support the rated capacity of the unit. The ball screw and nut are made from hardened alloy steel with hardened bearing balls carrying the load between nut and screw. This rolling action reduces friction between the nut and the screw permitting smooth and efficient movement of the load. Because of the greater efficiency and rolling action, the ball screw can operate at higher speeds or increased duty cycle when compared with the Machine Screw Jack. When a Ball Screw Jack is motorized, less horsepower is required than an equivalent size Machine Screw Jack. STAINESS STEE SCREW JACK ActionJac Stainless Steel Machine Screw Jacks are ideal for use in demanding environments where corrosion resistance is required. All external components are manufactured from Stainless Steel materials. These jacks use a stainless steel worm with a high strength bronze drive sleeve. The worm and drive sleeve are supported by tapered roller bearings and sealed to prevent loss of lubrication and to resist contamination. The stainless steel lifting screw threads are precision formed to Class -C (centralizing) thread profiles. oad capacities for Stainless Steel Machine Screw Jacks range from,00 to,000 pounds. For increased capacity, a -PH hardened worm is available. METRIC BA SCREW JACK With over twenty-five years of experience manufacturing precision worm gear screw jacks, Nook Industries has expanded the ActionJac offering to include metric models providing design engineers a globally accepted product. All the efficiency advantages that come with ball screw technology are available in ActionJac Metric Ball Screw Jacks. A full line of IEC motor mounts are available. TRAPEZOIDA SCREW JACK The ActionJac Trapezoid Screw Jacks utilize the same rugged design as the ActionJac Machine Screw Jacks. These true metric jacks include a lift shaft with a special trapezoidal thread form. This thread form has been created to stay within ISO standards yet retains the centralizing feature of our C acme threads. These jacks may be assembled with IEC motor mounts. ACCESSORIES Accessories such as motors, motor mounts, encoders, hand wheels, counters, couplings, miter gear boxes, boots, limit switches, top plates and clevises are available. NOTE: Units are not to be used as personnel support or movement. 6 nookindustries.com

3 WORM GEAR JACK CONFIGURATIONS AND GOSSARY TERMS WORM GEAR GOSSARY & TERMS JACK CONFIGURATIONS Worm gear screw jacks can be assembled in a number of different configurations. The first major configuration divides the jacks into translators and rotators. A translating jack has a lifting shaft that moves through the gear box. A nut is integrated with the worm gear such that the worm gear and nut rotate together. When the lift shaft is held to prevent rotation, the lift shaft will move linearly through the gear box to move the load. A rotating jack has a lift shaft that turns moving a nut. The lift shaft is fixed to the worm gear. This causes the load, which is attached to the travel nut, to move along the lift shaft. (SEE FIG. ) Both rotators and translators have an upright and inverted configuration. (SEE FIG. ) FIG. Mounting Flange ift Shaft Stem Cover UPRIGHT Travel Nut UPRIGHT ROTATING Housing Stem Cover INVERTED INVERTED ROTATING WORM GEAR SCREW JACK TECHNICA INTRODUCTION ANTI-BACKASH Anti-backlash Machine Screw Jacks are used wherever reversible load conditions require precision positioning control. Adjustable backlash Machine Screw Jack models are available to reduce backlash to approximately 0.00". An Anti-backlash Machine Screw Jack allows the lash between the drive sleeve thread and the lifting screw thread to be accurately controlled by adjusting the top cover of the jack. The anti-backlash jack design has an upper drive sleeve and a lower drive sleeve. Adjustment of the cover changes the relative distance between the drive sleeves. This change in distance compensates for any lash. Anti-backlash Machine Screw Jacks minimize backlash, but should not be used to completely eliminate backlash. While it may be desirable UPRIGHT ANTI-BACKASH MACHINE SCREW to totally eliminate backlash, the result would be a lock-up of lifting shaft and drive sleeve. Ball Screw Jacks can be factory adjusted to reduce backlash by selecting bearing ball size in the ball nut. This selective fit technique can be used to achieve a lash between the ball nut and ball screw of 0.00"-0.00". Precision ball screws with preloaded ball nuts can be supplied to achieve zero lift shaft backlash. (SEE FIG. ) INVERTED ANTI-BACKASH MACHINE SCREW KEYED JACK The lift shaft of a translating style jack must be attached to something which prevents the lift shaft from rotating. If it is not, the lift shaft (and the load!) will turn and not translate. A feature can be added to a machine screw jack to prevent lift shaft rotation. This type of jack is referred to as a keyed jack and is available in upright and inverted models. A keyed jack has a keyway machined along the length of the lifting screw. A matching key is fastened to the cover of the jack which will eliminate lift shaft rotation. nookindustries.com

4 WORM GEAR JACK CONFIGURATIONS AND GOSSARY TERMS WORM GEAR WORM GEAR SCREW JACK TECHNICA INTRODUCTION The keyway in the screw causes greater than normal wear on the internal drive sleeve threads, somewhat reducing jack life. Ball Screw Jacks can also be supplied with a device that prevents rotation of the lift shaft. Anti-rotation is accomplished by a square guide attached to the screw translating inside a square stem cover attached to the jack. The square stem tube is supplied with lube fittings. The illustrations show the different configurations of keyed screw jacks. (SEE FIG. ) DOUBE CEVIS JACK Double Clevis Jacks are used when it is necessary to move a load through an arc, such as tracking antennas, hinged doors and air dampers. FIG. UPRIGHT KEYED DOUBE CEVIS INVERTED KEYED Machine Screw and Ball Screw Jacks from -ton to -ton capacities can be supplied with double clevis mounts. One clevis is mounted on the end of the lift shaft and the other clevis is welded to a heavy duty stem cover which is welded to the housing. Double clevis designs are available with optional accessories such as boots, motor mounts, right-angle reducers, motors, encoders and rotary limit switches. To check column strength limitations for each application use the extended pin to pin dimension and the column strength chart on page 66,, 0, and 9. For greater column strength consider ActionJac Electric Cylinders, pages -. NOTE: Mounting hardware for double clevis jacks should be specified as heat treated alloy steel clevis pins with at least 00,000 psi ultimate tensile strength. (SEE FIG. ) TRAVE ENGTH As a manufacturer of lead screws, Nook Industries stocks a broad selection of inch and metric ball, acme and trapezoid screws in long lengths. Jacks are not preassembled or stocked with standard length screws. Each jack is made to order based on travel length. Nook Industries has the capability to manufacture long screws for special applications, limited only by the availability of raw materials. Rotating screw jacks may be assembled with a larger diameter lift screw for greater column strength. Jacks can be supplied with special pitch lift screws to change the jack operating speed. Jacks can also be assembled with twin lead screws if required by the application. Contact the engineers at Nook Industries for availability. TRAVE VS. INPUT REVOUTIONS The number of turns of the worm required to move one inch is a function of the worm gear ratio and the lead of the screw. The charts at the front of each section give the number of turns of worm for " raise for each jack. The motor speed divided by this number is the linear speed of the jack lift shaft or travel nut. Conversely, the desired travel rate multiplied by the turns of worm for " raise equals the input rpm required. EAD ACCURACY AND MATCHED EAD ead accuracy is the difference between the actual distance traveled versus the theoretical distance traveled based on lead. For example: A screw with a 0. inch lead and ±0.00" per foot lead accuracy rotated times theoretically moves the nut inches. nookindustries.com

5 WORM GEAR GOSSARY TERMS WORM GEAR Revolutions X.00 inches per revolution =.000 inches of travel with a ead accuracy of ±0.00" per foot, actual travel could be from.996 to.00 inches. The rolled thread ball screw, as employed in ActionJac products, is held within ±0.00" per foot lead error. The rolled acme thread screws used in our machine screw jacks have a typical lead accuracy of ±0.00" per foot. When multiple jacks are used to move a load with precise synchronicity, lift shafts of similar lead accuracy can be factory selected and supplied as sets. Consult factory for matched lead set tolerances. INPUT TORQUE The input torque is the rotary force required at the input of the jack to generate an output force at the lift shaft. The product specification pages show the torque necessary to raise one pound. This number multiplied by the load is the required input torque. Due to static friction, starting or breakaway torque can be as much as two to three times running torque. If the load is moved horizontally, the force required to move the load will be lessened in proportion to the coefficient of friction of the surface along which the load is moved. In addition, the force needed to start, stop and hold the load (inertia loading) is provided by the jack. Jack sizing should consider all these forces. If an application calls for several jacks to be driven together in series, input torque values should be limited to the three times the rated value of the first jack. For multiple high lead ball screw jacks or belt/chain driven jacks contact Nook Industries for allowable input torque values. Multiple jacks driven in a series may require operation at reduced load. TARE DRAG TORQUE The gear box components (bearings, seals and grease) in a jack add tare drag. The product specification pages show the tare drag torque. When loading ActionJac Worm Gear Screw Jacks with loads less than % of their rated capacity, tare drag torque needs to be added to the torque requirement. INPUT SPEED ActionJac Worm Gear Screw Jacks are rated for up to,000 rpm input speed, provided horsepower and temperature ratings are not exceeded. Contact Nook Industries engineers if higher input speeds are required. DUTY CYCE Duty cycle is the ratio of run time to total cycle time. Some of the mechanical energy input to a worm gear screw jack is converted into heat caused by friction. The duty cycle is limited by the ability of the worm gear screw jack to dissipate heat. An increase in temperature can affect the properties of some components resulting in accelerated wear, damage and possible unexpected failure. Maximum allowable horsepower ratings (see product specification pages) are based on intermittent operation. The approximate allowable duty cycles are: Ball Screw Jacks= % Machine Screw Jacks= % Housing temperature should be monitored and kept below 00 F maximum. Continuous or heavyduty operation is possible by de-rating the jack capacity, external cooling of the unit or through the use of a recirculating lubrication system. SEF-OCKING AND BRAKES Self-locking occurs when system efficiencies are low enough that the force on the lifting shaft cannot cause the drive system to reverse direction. Machine Screw Jacks having gear ratios between 0: and :, are self-locking and, in the absence of vibration, will hold loads without backdriving. All other ratios may require a brake to prevent backdriving. All Ball Screw Jacks can backdrive and require some means of holding the load, such as a brake on the motor. The product specification pages show holding torque values. Holding torque represents the amount of input torque required to restrain the load. In addition to back driving, system inertia usually results in some over travel when the motor is switched off. The inertia of the system should be considered when determining the brake size required to stop a dynamic load. TEMPERATURE All Actionjac Worm Gear Screw Jacks are suitable for operation within the specified limits provided that the housing temperature is not lower than -0 F or higher than +00 F. Factory supplied grease in standard units will operate in this range. For higher or lower operating temperature ranges contact Nook Industries. TRAVE STOPS Travel stops are not standard. A limit switch and a brake should be used to stop the motor. Mechanical stops can cause damage to the jacks because most electric motors will deliver stall torques much higher than their rated torques and motor inertia can cause severe shock loads. For hand operation, mechanical stops can be provided. WORM GEAR SCREW JACK TECHNICA INTRODUCTION nookindustries.com 9

6 WORM GEAR DESIGN CONSIDERATIONS WORM GEAR WORM GEAR SCREW JACK TECHNICA INTRODUCTION DESIGN CONSIDERATIONS BA SCREW VS. MACHINE SCREW JACK The decision to use a ball screw jack or a machine screw jack is based on the application. For many applications, a ball screw model is the best choice. Ball screw jacks are more efficient and therefore require less power than a machine screw jack in the same application. For low duty cycle applications, for hand-operated applications, or if backdriving is not acceptable consider a machine screw jack. Actionjac Ball Screw Jacks are preferred for: ong travel lengths ong, predictable life High duty cycles Oscillating motion Actionjac Machine Screw Jacks are preferred for: Resistance to backdriving Vibration environments Manual operation High static loads OAD CAPACITY All anticipated loads should be within the rated capacity of the jack. oads on the jack in most applications include: static loads, dynamic or moving loads, cutting forces or other reaction forces and acceleration/deceleration loads. For shock loads, the peak load must not exceed the rated capacity of the jack, and an appropriate design factor should be applied commensurate with the severity of the shock. For accidental overloads not anticipated in the design of the system, jacks can sustain without damage the following overload conditions: 0% for dynamic loads, 0% for static loads. For multiple jack systems, load distribution should be considered. System stiffness, center of gravity, drive shaft windup and lead variation in the lift shafts may result in unequal load distribution. Jacks of varying capacity with equal turns of worm for " travel may be used to accommodate unequal loading. HORSEPOWER RATINGS Maximum horsepower ratings are based on intermittent operation. The approximate duty cycles are: Ball Screw Jacks= % Machine Screw Jacks= % Horsepower is calculated by using the following formula: Horsepower per jack = Torque to Number raise one x of pounds x rpm pound to be raised 60 The product specification pages show the torque to raise one pound value for each jack. Add tare drag torque if operating under % rated load. Horsepower values are influenced by many application specific variables including mounting, environment, duty cycle and lubrication. The best way to determine whether performance is within horsepower limits is to measure the jack temperature. The temperature of the housing near the worm must not exceed 00 F. Do not exceed the maximum allowable input horsepower for a jack. Many models cannot lift the full rated load at,00 rpm. If the horsepower required exceeds the maximum value for the jack selected, several solutions are possible. Use a larger jack model to increase the maximum allowable horsepower Use a Ball Screw Jack to reduce the power required to do the same work Operate at a lower input speed Use a right angle reducer to bring the power requirement within acceptable limits Contact Nook Industries for additional assistance. COUMN STRENGTH Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength can be substantially lower than nominal jack capacity. If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the acme screw and ball screw technical sections for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength. Charts are provided in each section to determine the required jack size in applications where the lift shaft is loaded in compression. To use the charts (pages 66,, 0,, 9) : ) Determine the mounting condition and mark a point on the Maximum length line. ) Mark a point on the oad line, applying an appropriate design factor. CAUTION: chart does not include a design factor. 0 nookindustries.com

7 WORM GEAR DESIGN CONSIDERATIONS WORM GEAR ) Draw a line connecting the two marked points. Select a jack above the point where the line drawn crosses the Jack Sizes line. The charts assume proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw. JACK SIZING DATA Jacks are limited by two constraints: load capacity and horsepower. The load capacity of the jack is limited by the physical constraints of its components (drive sleeve, lift shaft, bearings, etc.). The horsepower limit of the jack is a result of the ability to dissipate the heat generated from the inefficiencies of its components. To size a screw jack for these constraints, application information must be collected. The data required is: ) Total oad The total load includes static loads, dynamic loads and inertia loads from acceleration and deceleration. Also consider reaction forces received from the load such as drilling or cutting forces when using a jack to move a machine tool. ) Number of Jacks The number of jacks used depends on physical size and design of the equipment. Stiffness of the equipment structure and guide system will determine the appropriate number of jacks required. Fewer jacks are easier to drive, align and synchronize. ) Maximum ength The maximum length includes travel, housing length, starting/stopping distance, extra length for boots and length to accommodate attachment of the load. ) Travel Rate Establishing a travel rate allows for evaluation of critical speed and horsepower limits. Acceleration/deceleration time needs to be considered when determining maximum required travel rate. ) Duty Cycle The duty cycle is the ratio of run time to the total cycle time. ong travel jacks may be limited by maximum temperature and not duty cycle. 6) Type of Guidance inear motion systems require both thrust and guidance. Jacks are designed to provide thrust only, not to guide the load. Guidance is based on application requirements. The guidance system must be designed to absorb all loads other than thrust. JACK SEECTION Once the jack sizing data is collected, a preliminary jack selection can be made and then verified. The steps are: ) Select a size and type of jack, Selection should be complete with the configuration (upright, inverted, rotating, etc.), ratio, travel or dimension, boots, lift shaft attachment, motor adapters or reducers. ) oad Per Jack Verify that the dynamic and static loads do not exceed the rated capacity of the jack. For multiple jack applications, check the distribution of the load based on the stiffness of the structure and potential uneven loading. ) Horsepower Calculate the maximum input horsepower required for each jack. This should not exceed the maximum input horsepower for the model and ratio selected. For multiple jack arrangements, total horsepower required depends on horsepower per jack, number of jacks, the efficiency of the gear box(es) and the efficiency of the arrangement. Two typical arrangements are: (SEE FIG. ) The efficiency of the arrangement based on the number of jacks is: Two jacks = 9% Three jacks = 90% Four jacks = % Six to eight jacks = 0% The efficiency of each miter gearbox is 90%. Therefore, motor horsepower requirement for the arrangement: Horsepower Arrangement = horsepower Number per x of jack jacks Efficiency Arrangement x of Each Gearbox If the horsepower required exceeds the maximum value for the jack selected, several solutions are possible. Use a larger jack model to increase the maximum allowable horsepower Use a Ball Screw Jack to reduce the power required to do the same work Operate at a lower input speed Use a right angle reducer to bring the power requirement within acceptable limits WORM GEAR SCREW JACK TECHNICA INTRODUCTION nookindustries.com

8 WORM GEAR DESIGN CONSIDERATIONS WORM GEAR WORM GEAR SCREW JACK TECHNICA INTRODUCTION ) Column Strength If it is at all possible for the lift shaft to be loaded in compression, check the column strength. Consider cases where a shaft normally loaded in tension may be compressively loaded if it meets an obstruction. Check horizontal applications for compressive loading due to acceleration or deceleration. If column strength is exceeded for the jack selected, consider the following options: Change the jack configuration to put the lift shaft in tension Increase size of jack. For rotating jacks add a bearing mount (like the EZZE-MOUNT ). FU FEX COUPING FU RIGID COUPING GEAR BOX TYPE E GEARMOTOR FIG. Change the lift shaft mounting condition (e.g. from clevis to top plate). ) Brakemotor Sizing Safety is the most important consideration. A brakemotor is recommended for all ActionJac products where there is a possibility of injury. Only 0: or greater ratio Machine Screw Jacks can be considered self-locking in the absence of vibration. The horsepower requirements determine the size of the motor. Upon selecting a brake motor, verify that the standard brake has sufficient torque to both hold the load and stop the load. Caution: High lead ball screw jacks may require larger nonstandard brakes to stop the load. An appropriately sized brake will insure against excessive drift when stopping for both the Ball Screw and Machine Screw Jacks. 6) Cycle Time Verify the duty cycle for the selected jack. Recommended duty cycles are: Ball screw jacks = % Machine screw jacks = %. The ability of the jack to dissipate the heat that builds during operation determines duty cycle. Anything that reduces the amount of heat generated or increases heat dissipation will allow higher duty cycles. Jacks may be limited by maximum temperature (00 F) and not duty cycle. Contact Nook Industries for assistance with these applications. ) ife For Ball Screw Jacks, verify ball screw life expectancy using the life charts. Note: Ball screw life charts are located at the beginning of each ball screw jack section. (Page 6 & 9) INSTAATION Alignment of the jack (or jacks) directly affects service life. Jacks must be properly aligned in all planes so that the main drive shaft can be turned without evidence of binding. The following steps are suggested but may not always be applicable when installing jacks. It is the responsibility of the end user to determine specific installation procedures. ) The mounting flange of the jack is a precision-machined surface. The worm shaft and lift shaft bearing bores are machined in tight relationship to the mounting flange. Better mounting surfaces will make it easier to align the jack to the load. The surface(s) to which the jacks are mounted should be flat, smooth and perpendicular to the guides. Note: for rotating worm gear screw jacks, also ensure that the lift shaft is parallel to the guides. nookindustries.com

9 WORM GEAR DESIGN CONSIDERATIONS WORM GEAR ) Start with the load temporarily supported in a position closest to the jack housing(s). ocate the jack by putting the jack in place with the fasteners loosely assembled. ) evel the jacks if necessary. For some applications, a piece of compliant material such as the rubber used for machine isolation bases will help compensate for potential misalignment. ) Check the level of the load, then, actuate the jacks bringing the lift shaft or travel nut nearly in contact with the load. Adjust the position of the jacks so that the jack attachment points are centered on the load mounting points. Tighten the jack mounting screws. If a compliant material is installed, make sure that the fasteners do not compress the material and that there is clearance around the fasteners. ) Rotate the worms to adjust the timing of the lift shafts as necessary to equally distribute the load. Assemble the load mounting hardware and tighten. MAINTENANCE ActionJac Worm Gear Screw Jacks require minimum maintenance. In addition to maintaining lubrication levels in the gearbox, the following items should be checked: ifting screws must be kept free of contaminants. If possible, screws should be booted or returned to retracted position when not in use. For Machine Screw Jacks, lash between the lift shaft and travel nut (or drive sleeve) greater than / the screw pitch indicates the need for replacement of the jack lift shaft drive components. For Ball Screw Jacks, the ball screw should be checked periodically for spalling of the raceway. In normal operation, ball screw lash does not change significantly over the life of the ball screw. For all jacks, check the backlash between the worm and worm gear. ash in excess of 0 for ratios : to : and 60 for ratios 0: and : indicates the need to replace the worm and worm gear. housing, remove the pipe plug and fill the unit until grease exits the pipe plug opening. Over filling the jack may result in grease leakage from the worm shaft seals. In normal operation, jack lubricant levels should be checked once per month. Application conditions may dictate a more or less frequent lubrication cycle. In extreme conditions, automatic lubrication may be desired. ubricants containing additives such as molydisulfide or graphite should not be used. Ball Screw models need only a light film of lubricant on the lift shaft for most applications. Nook E-900 Ball Screw ubricant may be applied with a cloth or spray. Operating a Ball Screw Jack lift shaft without lubrication will result in a ninety percent reduction in life. E-900 BA SCREW UBRICANT page 9 WORM GEAR SCREW JACK TECHNICA INTRODUCTION 6) Cycle the jacks from closest to farthest point. For rotating jacks with a lift shaft bearing support, loosen the bearing support fasteners and re-tighten to ensure that the lift shaft is parallel to the guide system. Failure to do this could result in lift shaft stress fracture. ) Cycle the jacks again and verify that no binding occurs. Check the lubrication levels, check the limit switch settings (note: rotary limit switches are not factory set), check the tightness of all fasteners and put the jacks in service. UBRICATION ActionJac Worm Gear Screw Jacks require lubrication to operate efficiently and with maximum life. Standard lubrication is NGI # grease. ubricants are available for both high and low temperature application. If operating conditions exceed 00 F. or -0 F., contact Nook Industries for alternative lubricants. The jack gear boxes are shipped pre-greased unless otherwise specified. Before operating any unit, check the lubricant level. All jack housings are furnished with a grease fitting. Most have a pipe plug opposite the grease fitting.

10 WORM GEAR APPICATION EXAMPES WORM GEAR WORM GEAR SCREW JACK TECHNICA INTRODUCTION Application # EXTRUDER SYSTEM A manufacturer of candy is retrofitting an extruding machine. The machine presently uses a hydraulic ram attached to a plunger to push a thick candy mixture through a dispensing tube into a mold. The manufacturer is concerned with contamination from leaking hydraulics and would like more consistency in the dispensing rate and volume. SPECIFICATIONS: Force to push the candy is 00 pounds (no load on retraction) Force is vertical and will put the jack lift shaft in compression Minimum speed is inch per second Actuation cycle: 0 times/hour, hours/day, 00 days/year Desired design life is two years Mechanism must be mounted overhead Maximum stroke is inches Food processing plant requires cleanliness ANAYSIS: Configuration: Speed, duty cycle and orientation of the operation dictates the use of an inverted ball screw jack. The plunger mechanism will be attached to the travel nut of a rotating jack. Column Strength: Using the application data (00 pound load, inch travel with an dimension of inches, assume mounting condition A ) with the column strength chart shows that the a five ton or larger jack will handle the compressive load. Speed and Horsepower: The 0. inch lead lift shaft in a ton ball screw jack will provide the proper speed: inch per second X 60 seconds per minute x.66 turns of worm for " raise = 60 input rpm. Horsepower required (Torque to raise one pound (from chart) X oad (lbs) X Worm Speed (rpm)/60 = (.0 X 00 pounds X 60) /60 =.6 Horsepower.6 Horsepower is below the three horsepower limit for this jack. Use a speed control with a motor rated for at least.6 horsepower at 60 rpm for this application. ife: The life, based on the Ball Screw ife Expectancy chart on page 6, is at least,06,000 inches of travel for a standard inverted rotating ton jack with a 00 lbs load. Calculated life is loaded inches per cycle X 0 cycles per hour X hours per day X 00 days per year =,00,000 inches per year or two years of life. SEECTION: Reference Number: From page 6, put together a reference number for the following: ton ball screw jack, inverted rotating configuration, 6: worm gear ratio, motor mount with Hp phase motor and motor mount on the input shaft, standard extensions for the output shaft, flange base, travel nut orientation A, dimension of " for a " travel. astly the jack will be modified to include food grade grease and epoxy paint. -BSJ-IR 6:/0-/SSE-/FA//M M= food grade grease and epoxy paint. Application # MACHINE TOO FIXTURE OADER A manufacturer is building a system to position a machine tool table horizontally inside the machine. SPECIFICATIONS: The table is well guided and weighs,000 pounds The fixture needs accurate and repeatable positioning The table moves only a few times per shift. Stroke length is 0 inches maximum Desired design life is two years Thrust can only be applied at two corners No specific speed requirements ANAYSIS: Configuration: Infrequent operation suggests a machine screw jack. Application arrangement, available clearance and good guidance allow the use of upright translating jacks. The jacks must have an adjustable anti-backlash feature to assure accurate bidirectional positioning. Two manually operated jacks will be used, connected with a common driveshaft. Column Strength: Even though the unit is horizontal, column strength must still be considered. Using the application data (000 pound load, 0 inch travel, assume mounting condition C ) with the column strength chart shows that a ton upright jack with " diameter screw will handle the potential compressive load of 000 lb per jack. Input Torque: This is a horizontal, manually operated system. The force required to move the load is the actual load times the coefficient of friction of the guide system. For example, if linear bearings were used, the force required to move the load would be equal to 000 pounds times.00 or pounds. The torque required to move pounds with a 6: ratio jack is 0.00 times or. in-lbs. This could easily be supplied by an operator turning a handwheel.

20 WORM GEAR ROTARY IMIT SWITCH WORM GEAR Every motorized Worm Gear Screw Jack must be controlled so that power to the motor is turned off and the brake engaged before the limits of mechanical travel are reached. WORM GEAR SCREW JACK ACCESSORIES TECHNICA DATA The ActionJac rotary limit switch senses extension shaft rotation and provides switch contact closures that can be used to control motors. This sturdy, durable assembly is available with two or four circuits or two circuits and a potentiometer. Each circuit has a separate rotating cam that actuates a high quality switch. The switch actuation may be individually and infinitely adjusted anywhere within the travel of the jack. These assemblies contain gear reducers with ratios that vary according to the model and travel of the jack. Nook selects ratios that result in maximum cam rotation for best accuracy, repeatability and minimum hysteresis. In most cases, with full travel of the actuator, the cam will rotate / to / of a revolution to actuate a switch. In the event that the cam continues to rotate, the switch returns to its original state after approximately of rotation, with no damage to the limit switch assembly. The -circuit switch assembly is useful for limiting the maximum and minimum extension. The -circuit assembly gives the possibility of additional signals for other user purposes. The potentiometer version is used to provide an analog signal for sensing jack position. Single Pole Double Throw (SPDT) switches are standard and Double Pole Double Throw (DPDT) switches are optional. These assemblies are dust protected and meet NEMA and standards for oil and water tightness. The ActionJac rotary limit switch assembly is mounted to the extension shaft side of the ActionJac Worm Gear Screw Jack opposite the input. The rotary limit switch is available for ActionJac Worm Gear Screw Jack sizes tons and larger. Most jack models have close and extended mounts to provide clearance around the switch housing. See the following chart for dimensions. Switches are factory installed to assure proper assembly in the correct orientation for the specified mounting position. CAUTION: imit switches are not adjusted at the factory. Switches should be set during installation. HOW TO ORDER ROTARY IMIT SWITCH: : imit Switch code (see table to right) Mounting Position ( through see page 6) Close or Extended Mount (C or E) Insert the correct designation in the ActionJac Worm Gear Screw Jack reference number (see page 6 and 9 for more information on jack reference numbers).

22 WORM GEAR FEXIBE COUPINGS WORM GEAR WORM GEAR SCREW JACK ACCESSORIES TECHNICA DATA Jacks used alone or in multiple arrangements require couplings to transmit power to the input shaft. Nook Industries provides jaw type and flex type couplings for use with jacks. The selection process for couplings includes the following steps: ) Refer to the jack specification tables to determine torque requirements per jack for your application. ) Determine total coupling capacity required by multiplying the torque required per jack by the number of jacks to be driven by the coupling. ) Check the torque required against maximum torque rating as shown in the table. Select a coupling with a maximum torque greater than the application torque. ) If using flex type couplings, full-flex couplings should be used for close coupled arrangements. For floating shaft applications, use two Flex- Rigid couplings. The rigid half should be mounted on the floating shaft. All jacks, shafts, couplings and motor should be carefully aligned for maximum performance. Couplings with bores other than those specified are available upon request. JACK PART NO.

23 WORM GEAR POWERSHAFT INK SHAFTING WORM GEAR ActionJac inkjac ine Shafting is used to interconnect the input shafts of ActionJac Worm Gear Screw Jacks used in a multiple arrangement. The shafts transfer the torque from the motor to the jack or from jack to jack. Nook Industries inkjac ine Shafting is made from steel and is available in standard lengths up to ". Custom end machining and other diameters are available, contact Nook Industries for information. SEECTION: There are two major concerns when selecting interconnect shaft: Critical Speed: How fast will the shaft be turning? Torque: How much load will the shafts be carrying? The two characteristics of a inkjac ine Shaft which can be varied to accommodate these requirements are: ength of the shaft Diameter of the shaft When selecting a inkjac ine Shaft, use the largest diameter or shortest length which satisfies both of the following equations. If you know length and operating speed of the shaft: x N = Minimum Diameter of the.6 x 0 6 inkjac Shaft in inches WHERE: = length of unsupported shaft in inches N = operating speed in revolutions per minute If you know the torque to be transmitted and the length of the shaft: (T x x x 0-6 ). = WHERE: T = torque in inch-pounds = total length of shaft in inches Minimum Diameter of the inkjac Shaft in inches DESIGN INMATION: The length used in the Speed-ength-Diameter Calculation is the supported length of the shaft. If support bearings are used on the shaft, the length is the longest unsupported length between bearings. The formulas above give a theoretical value of critical speed. Alignment, straightness and stiffness of the system all contribute to determining the actual value. The formula used for finding minimum diameter when torque and length are known is based on an allowable twist of. Restricting the twist allows for better synchronization of ActionJac motion. The torque in the system is also limited by the torque capacity of the coupling. Allow / inch spacing between the jack input shaft and the inkjac shaft inside the coupling. For some combinations of couplings and jacks, the radius of the suggested coupling is larger than the distance from the center of the worm shaft to the base. Nook Industries offers a range of couplings for use with inkjac and ActionJac products in both floating shaft and supported shaft applications. See page for more information.

32 INCH BA COUMN STRENGTH: INCH BA WORM GEAR Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity. Mark a point on the oad line, applying an appropriate design factor. CAUTION: chart does not include a design factor. INCH BA TECHNICA DATA If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the ball screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength. Charts are used to determine the required jack size in applications where the lift shaft is loaded in compression. To use this chart: Determine the mounting condition and mark a point on the Maximum length line.

Select a jack above the point where the line drawn crosses the Jack Sizes line. The chart assumes proper jack alignment with no bending loads on the screw. Effects from side loading are not included in this chart. Jacks operating horizontally with long lift shafts can experience bending from the weight of the screw.

51 WORM GEAR INCH MACHINE MACHINE The worm gear driven Machine Screw Jack incorporates an alloy steel worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent loss of lubrication (sealed radial bearings on the / and ton units). The drive sleeve is supported on anti-friction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the acme thread lifting screw to translate or rotate, depending upon jack configuration. The jack housing is made of ductile iron (MJ models have aluminum housings, aluminum optional on one ton models) and proportioned to support the rated capacity of the unit. The lifting screw is made of alloy steel with a minimum tensile strength of 9,000 psi. The threads are precision formed, typically using Class -C (Centralizing) tolerances. Jack lift shaft lead tolerance is approximately ±0.00" per foot. See the technical introduction at the beginning of this section for additional Machine Screw Jack features and comparison to Ball Screw Jacks. INCH MACHINE TECHNICA DATA nookindustries.com

54 INCH MACHINE COUMN STRENGTH: INCH MACHINE WORM GEAR Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity. Mark a point on the oad line, applying an appropriate design factor. CAUTION: chart does not include a design factor. INCH MACHINE TECHNICA DATA If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the acme screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength. Charts are used to determine the required jack size in applications where the lift shaft is loaded in compression. To use this chart: Determine the mounting condition and mark a point on the Maximum length line.

73 WORM GEAR COUMN STRENGTH: INCH STAINESS STEE JACKS STAINESS Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity. Mark a point on the oad line, applying an appropriate design factor. CAUTION: chart does not include a design factor. If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the acme screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength. Charts are used to determine the required jack size in applications where the lift shaft is loaded in compression. To use this chart: Determine the mounting condition and mark a point on the Maximum length line.

84 METRIC BA COUMN STRENGTH: METRIC BA WORM GEAR Column strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength may be substantially lower than nominal jack capacity. Mark a point on the oad line, applying an appropriate design factor. CAUTION: chart does not include a design factor. METRIC BA TECHNICA DATA If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw. Refer to the ball screw technical section for critical speed limitations. If there is any possibility for the lift shaft to go into compression, the application should be sized for sufficient column strength. Charts are used to determine the required jack size in applications where the lift shaft is loaded in compression. To use this chart: Determine the mounting condition and mark a point on the Maximum length line.
