Indexing In this mode of operation, reciprocating motion applied to the driving race of the clutch is transformed into uni-directional intermittent motion at the driven race. or example, on a feeding roller, the clutch is mounted on the roller and a torque arm is connected to the driving race of the clutch. crank motion mechanism provides reciprocating motion to the driving race. The clutch drives in the forward stroke (index) and overruns on the return stroke, resulting in intermittent uni-directional motion of the feeding roller. Please reference igure 2 for an example of a typical indexing application. Indexing pplication & Selection begins on page 17. igure 2: General indexing application example Tsubaki am lutch products are designed to transmit torque in one direction of rotation, and overrun (freewheel) in the opposite direction of rotation. ll Tsubaki am lutch products utilize the same principles of operation. Tsubaki offers various series of products to address the many types of applications where am lutch products are most often used. The three most common types of applications are listed below. 1. ackstopping In backstop applications, the clutches are used to prevent reverse rotation of drive shafts, which may cause damage to machinery and other expensive equipment. With the outer race of the clutch anchored stationary, the inner race can overrun freely in one direction of rotation. Reverse rotation is instantaneously prevented by the automatic engagement of the clutch. Typical backstop applications are in conveyor systems and gear reducers. Please reference igure 1 for an example of a typical backstopping application. ackstopping pplication & Selection begins on page 11. igure 1: General backstopping application example application haracteristics am lutch model options ow speed overrun ess than 1 r/m S, S-HS, S-R, SU, US200, MZU, MZ, MGUS, MGUS-R, TS, TSS, Medium speed overrun 1 to 700 r/m RU, R-T, US200, MZU, MZ, MGUS, MGUS-R, TS, TSS, High speed overrun 700 to 3,600 r/m RU, R-HT, MGUS-R, MZU, MZ, TS, TSS, application haracteristics* am lutch model options High speed, Small feed angle ow-medium speed, Small feed angle ow speed, arge feed angle ackstop device for indexing Infinite variable feed RQUNY: More than 300 times/m NG: ess than 90 RQUNY: ess than 300 times/m NG: More than 90 RQUNY: ess than 1 times/m NG: More than 90 RQUNY: ess than 300 times/m NG: More than 90 RQUNY: ess than 300 times/m NG ess than 90 * NG is the degree of rotating that the am lutch must accommodate while indexing. See page 17 for more details. am ehavior and am lutch Operation In indexing applications, reciprocal movement of a certain angle (0) is provided at the outer race of the am lutch to perform engagement and overrunning in turn continuously and obtain intermittent rotation. In the case of the am lutch shown in the figure to the right, when the outer race moves from to, the am lutch engages to rotate the inner race (of the driven side) by angle 0, i.e., from a to b. However, the am lutch does not operate to stop the inner race at position b. When the outer race rotates in reverse from to, the am lutch overruns while the inner race (of the driven side) does not rotate. y repeating this sequential movement, the inner race (of the driven side) rotates intermittently within the preset angle (0). ontact Tsubaki MIUS, PUS, MZU, MZ, TS, TSS, ontact Tsubaki MIUS, PUS, MZU, MZ, TS, TSS, MIUS, PUS, MZU, MZ, TS, TSS, b θ a Reciprocal movement of the outer race Intermittent movement of the outer race 1 2

5 am luth basis 3. Overrunning lutches used in this type of application overrun at either the inner or outer race during the majority of the clutch operating time, and are occasionally called upon to lock up and drive. typical application is a two-speed drive, where an electric motor and a geared motor are connected to a single driven shaft through one-way clutches. The machine can be driven by either the electric motor or geared motor. When the geared motor drives at low speed, the clutch engages. When the faster turning electric motor drives the machine, the clutch overruns. The clutch automatically switches between low speed and high speed. Please reference igure 3 for an example of a typical overrunning application. igure 3: General Overrunning application example am luth basis 4. asic am lutch onstruction igure 4 provides a sectional view of the components which reside inside of a Tsubaki MZ Series am lutch.

This action causes engagement (clutching) and disengagement (overrunning) of the clutch inner and outer races. The cams are the vital component of a am lutch, and they are available in various models and types to suit a variety of applications. The inner and outer surface of the races are hardened and precision ground to enable the ability to withstand high compression stress during cam engagement. Spring ompressed springs are set at both ends of the cams to ensure that all of the cams contact the inner and outer races at all times. Thus, the cams are always ready for immediate engagement. This is extremely important so as to ensure that the load is spread evenly across all cams when they engage with the inner and outer races. earing The bearings maintain concentricity of the inner and outer races and bear the radial load for the engagement of the cams and the inner and outer races. Maintaining concentricity is particularly important to ensure that the load is spread equally and simultaneously over the cams at the time of engagement. 3 4

6 am luth basis am luth basis ll Tsubaki am lutches use a cam type construction. This is also referred to as a sprag style clutch. n older style clutch which Tsubaki does not supply is called a Ramp & Roller or simply a "Roller" clutch. The following is an explanation of the features of each type. This discussion mentions Tsubaki S Series backstop clutches but is relevant to other Tsubaki am lutches. Non-rollover ackstop am General am onstruction operating PriniPles The outer race's rotation is stopped by the torque arm. ams contact with the inner and outer races at points and respectively. maintains a constant engagement angle (strut angle º) with the center line O-O'. The strut angle is an integral part of the overrunning and engagement function of the S am lutch. See 1. 1 am O' Spring Outer race Inner race Overrunning O ngagement Strut angle(º) Springs give the rotational moment of to cams ensuring precise contact is maintained between the inner and outer races. When the inner race (conveyor shaft) rotates in the direction of the black arrow, the inner race overruns smoothly because does not act as a strut. t this time, cams maintain light contact due to the spring force. See 2. 2 am ams and their constructions The S Series am lutches use non-rollover cams which provide an additional level of safety. ven if a am lutch has been selected appropriately for an application, unanticipated loads can occur. With a traditional cam profile, as used by some manufacturers, the unanticipated load might cause the cam to rollover, allowing the conveyor to move backward. The cam profile used by Tsubaki is most suited for the backstopping function, placing importance on the load distribution among multiple cams and a large surface cross section. ven if an unexpectedly large reverse torque occurs, the clutches will not roll over, preventing the conveyor from reversing. Outer race Roller am Small size S am lutches use a structure where cams and rollers are arranged alternately, and rollers act as a bearing to maintain the concentricity of the inner and outer races. When the conveyor stops and the inner race (conveyor shaft) rotates in the direction of the white arrow, the inner race is locked immediately by the cams because acts as a strut, and prevents the conveyor from rotating in reverse. See 3. 3 Spring O' Spring Inner race O Overrunning Strut angle(º) ngagement Outer race age-ring Inner race Spring Small size am lutch construction and cam profile Outer race am Inner race Spring arger size am lutch construction and Non-rollover cam design arge size S-HS series am lutches use a unique cam cage and structure supporting both sides with bearings, making it possible to use at a higher overrunning speed. dditionally, torque capacity is significantly increased allowing the large conveyor to be operated much more safely. Self-lubrication function When the inner race overruns, rollers also rotate so the cam and roller cage orbit around the outer circumference of the inner race at low speed. Grease in the cam and roller cage spreads completely throughout the insides of the am lutch due to the orbital motion, thus maintaining good lubrication. V2 Roller V1 am 5 6

7 am luth basis isplaement of ontat PoinT funtion Rollers function as bearings and orbit while rotating on their axis, and supporting the outer race. There is a slight clearance between the rollers, the inner and outer races; therefore the bottom of the cam space between the inner and outer races is slightly wider compared with the top. ams always maintain contact by spring force, and the slant of the cams is automatically different at the top and the bottom. ams continuously orbit by changing the contact point with the inner and outer races; therefore the wear on cams due to overrunning is diminished to the minimum, and the overrunning wear life on the am lutch is at the maximum length. Outer race ifferent inclination Inner race Slightly narrow Slightly wide or the conveyor, which is always in an overrunning condition during the operation, as well as the selflubrication function and the sliding speed diminishing function, it is one of the major features of a cam and roller cage to realize a long operating life. Tsubaki S and S-HS am lutch compared with Ramp & Roller lutch am lutch cams slide on the outer circumference of the inner race (i) at the decelerated sliding speed due to the sliding speed diminishing function described above. The contact force of cams and inner and outer races are given only by spring force (Ps). s for the Roller lutches, rollers slide in the inner circumference of the outer race (o) because rollers are built onto a roller cage which is connected with the inner race. am lutch Roller lutch Ps Therefore the sliding speed of the Roller Pc lutch is faster when compared with that of the am lutch between the cams and inner race. In addition, the contact force of Ps V2 rollers and the outer race is quite large in the o Ramp & Roller design because the centrifugal force (Pc) caused by the rotation of the roller cage is added to the spring force (Ps). i The S am lutches overrun with low sliding speed and low contact force, thus the S am lutches have a long overrunning wear life when compared with the Roller lutches. S/S-HS Series br-ht, bru sris innovation non-ontat esign extens servie life Greatly Increased Service ife Made possible by Tsubaki s extensive experience in mechanical power transmission, the cams used in the R am lutch offer a unique cross section that provides positive mechanical engagement only when needed. Otherwise, the am lutch rotates freely with absolutely no mechanical contact in the clutch mechanism. The result is a greatly increased service life compared to conventional types. ackstop pplications with High-Speed Overrunning When the am lutch is stationary, the cam locks the inner and outer races together (igure 5). When the inner race (load side) overruns at a high speed, the cam disengages by releasing the inner race (igure 6). When the inner race stops, the cam rotates back into an engaged position. If the inner race tries to rotate in the reverse direction, the cams then serve as a stop between the anchored outer race and inner race to prevent reverse rotation and provide backstopping. High-Speed and ow-speed-ngaged Overrunning When the am lutch is stationary, the cam locks the inner and outer races together (igure 5). When the inner race (load side) overruns at a high speed, the cam disengages by releasing from the inner race (igure 6). When the high-speed rotation of the inner race stops and the inner race begins to rotate slowly, the cam rotates back into an engaged position. Then when you start to drive the outer race at low speed of rotation, the cams serve as a prop and drive the inner race at the same low speed of rotation. Please reference igure 7. More conomical esign The open-type R Series features a simple design in which the am lutch mechanism is incorporated in a cage between standard dimension inner and outer bearing races. This allows the am lutch to be easily and economically integrated into a wide variety of mechanical systems. Tsubaki also offers a packagetype am lutch that incorporates a bearing assembly to reduce maintenance demands.

9 backstop clutch selection Guide bakstopping To PrevenT reverse rotation backstop am lutch is used to prevent the rotating shaft from being driven in the reverse direction. The am lutch will continue overrunning while the shaft rotates and engages to prevent reverse shaft rotation. Normally, the inner race is mounted on the rotating shaft, and the outer race is fixed to the machine frame. The inner race overruns in normal operation. s soon as the shaft begins to rotate in the reverse direction, the cams engage with the inner and outer races to prevent reversing. igure 8 depicts a typical setup for installing a backstop am lutch. ackstop am lutch Speed Grouping ackstopping am lutches are grouped into three different speed classifications that are dependant on the overrunning speed and load conditions. The following table provides the three different classifications for consideration. ree run am igure 8: Typical backstop installation Outer race Inner race arm bakstop am luth mounting orientation Preventing reverse rotation of inclined and vertical conveyor systems is one of the most common application solutions provided when implementing a backstop am lutch.

10 backstop clutch selection Guide bakstopping for low spee overrunning (overrunning at 1 rpm or less) bakstopping for high spee overrunning (overrunning at 700 To 3,600 rpm) In this application, the inner race is mounted directly onto the conveyor head pulley, or driven shaft. The outer race is connected to the conveyor frame to prevent reverse rotation. Since reverse rotation is prevented directly by the conveyor shaft without using a drive chain, gears, or couplings, this is regarded as the safest and most reliable mounting method. urthermore, due to the fact that the am lutch is connected to the conveyor pulley, low overrunning slip speed is reduced, as well as the slipping distance. The result is reduced wear and long service life. In addition to conveyor systems, this system is also used to prevent reverse rotation on inclined and screw type pumps. Please see igure 10 for an illustration of mounting. large scale inclined belt onveyors Motor oupling Main Shaft Inclined elt onveyors In this application, the gear reducer is tasked with driving a large scale inclined conveyor system. The am lutch is installed to prevent the conveyor from rolling backwards in the event of stoppage or overload. s depicted in igure 12, the am lutch is mounted directly onto the reducer to prevent damage that would result due to reverse rotation.

Therefore, the am lutch required only needs to withstand a comparatively small torque that is inversely proportional to the rotating speed ratio of the reducer output shaft. onsidering the application requirements, even a small am lutch can be utilized in this application. igure 11 provides an illustration of how the am lutch could be mounted for this particular application. am lutch Typical series MGUS/MGUS-R advantages ompact design can handle high torque xcellent wear characteristics igure 12: am lutch installed on gear reducer Pump & ompressor systems Pump or ompressor am lutch oupling Motor igure 13: am lutch installed on pump/compressor system Pump/ompressor Systems There are many applications in which multiple pump or compressor systems are feeding into the same line.

11 ackstop lutch Selection Guide InformatIon for SelectIon ackstop SelectIon ackstop clutches by definition are required to hold back a load from moving in a reverse direction. are must be taken in calculating the torque requirements and should be based on maximum or worst case conditions and not averages or normally seen loads. ecause the failure of a backstop or holdback clutch might result in damages, take time in considering all the possible loadings and select appropriate service factors. elow is more than one selection formula; it is generally advised to select the am lutch that provides the largest safety factor. General Selection method: ) alculate the static torque reverse motion based upon the maximum load expected and multiply it by the service factor. Selection is based on the formula to the right. ) Select the clutch by: 1) esign torque requirement 2) Maximum overrunning speed 3) ore size and installation method motor Stall torque Selection method: nother method commonly used to select the proper backstop clutch size for conveyors is to use the motor name plate ratings plus the motor's ability to produce excess torque. epending on the motor size, it may develop over 300% of rated torque. fter stalling an overloaded conveyor can overload the backstop. or proper selection of the backstop, all facets of the mechanical system should be considered to ensure that the backstop is not the weakest link in the conveyor drive. If the motor breakdown torque is not known, refer to the motor manufacturer. NOT required torque x Service factor = esign torque The torque capacity of the selected am lutch must be greater than the design torque requirement, must accept the maximum overrunning speed, and be suitable for the bore and installation method required. Selection is based on the following formula: Motor stall torque T(lb.ft.) = Motor power hp x 5252 x Shaft speed N (r/min) or Motor stall torque T(N m) = Motor power kw x 95 x Shaft speed N (r/min) Select service factor from table below: S Service condition 1.5 ackstopping: Several times a day 2.0 ackstopping: More than several times a day lways allow for the maximum possible load in your calculations, since backstopping often occurs when the conveyor is loaded above its normal loading capacity. S 100 < _ T max S 100 < _ T max S = Stall torque percentage Must be greater than 100% and should be obtained from motor manufacturer T max = capacity of the am lutch and must be greater than the motor stall torque ucket elevator Selection method: The torque capacity of the selected am lutch must be greater than the calculated torque (T), must accept the required shaft speed, and be suitable for the bore and installation method required. Metric formula: T(Nm) = 9.8 x ( + ) x Q x x 1000 x Service actor 120 x V elt conveyor Selection method: Using these calculations, a slightly smaller am lutch might be suggested because friction factors inherent in the belt conveyor are taken into consideration. ny calculations from this formula should be compared with the Motor Stall Selection Method. We strongly suggest that any am lutch selection be based on the larger value and choose the am lutch that provides a greater safety factor. Please contact Tsubaki with any questions.

In the case of the am lutch shown in igures 14, 15, when the outer race moves from to, the am lutch engages to rotate the inner race (of the driven side) by angle 0, i.e., from a to b. However, the am lutch does not operate to stop the inner race at position b. When the outer race rotates in reverse from to, the am lutch overruns while the inner race (of the driven side) does not rotate. y repeating this sequential movement, the inner race (of the driven side) rotates intermittently within the preset angle (0). This angle of movement (0) is referred to as the "feed angle" that the am lutch must accommodate. b θ a Reciprocal movement of the outer race Intermittent movement of the outer race (1) indexing applications with: high spee an small fee angle (feed frequency: n = 300 to 1,200 times/m) (feed angle: 0 = up to 90 ; n x 0 = 20,000 max) The example in igure 16 shows a roll feeding device which is frequently used in high-speed automatic clamp presses. riving power is taken from the eccentric disk provided at the end of the continuously rotating crankshaft, and this power drives the feed rolls intermittently through a am lutch. The feed length can be changed quickly and easily for improved work efficiency. In order to attain high-speed, high-precision feeding, a cone brake with less torque fluctuation and a am lutch for backstopping are used together. (2) indexing applications with: meium an low spee an small fee angle (feed frequency: n = up to 300 times/m) (feed angle: 0 = up to 90 ; n 0 = 20,000 max.) Indexing in this application range is applicable to many machines. igure 17 shows an example of a paper feeding section on an automatic stapler. The reciprocating movement of the eccentric disk is converted by the am lutch into an intermittent feed motion, which drives the belt conveyor. Hence, stapling is timed to the intermittent feeding motion and load overrun is prevented by a brake. Stapling is done at an exact pitch.

13 ( ( ( ( ( indexing clutch selection Guide (3) indexing applications with: low spee an large fee angle (feed frequency: n = up to 1 times/m) (feed angle: 0 = 90 and up; n 0 =,000 max.) Segmented gears and rack & pinions are often used to produce the reciprocal movement to be transmitted to the am lutch. igure 18 gives an application example of a pouch-making machine. Since the reciprocating movement of the eccentric disk is accelerated through the rack & pinion assembly, the reciprocal action of the am lutch outer race is enlarged to 860. uring production the vinyl sheet feeding length is indexed at a speed of 40 to 60 times per minute. In this case, the acceleration of the am lutch increases, a large torque acts repeatedly, and the cam slipping distance at overrunning becomes longer. Hence, a cam is required that has superior engagement and higher anti-abrasive properties. brake is used in order to improve the precision of the vinyl sheet feeding pitch. igure 18: Indexing am lutch used in feed roll application (4) indexing applications with: feeing with stopper (feed frequency: n = up to 300 times/m) (feed angle: 0 = up to 90 ) In this application, a stopper holds the material to be indexed at a position just before the feed end point, providing a fixed feeding pitch. s soon as the material hits the stopper, a torque shock load larger than the torque required for feeding is applied to the feeding roll which is still rotating. igure 19 below shows an example of a am lutch used in a bolt header. The wire is fed intermittently by a am lutch mounted on a grooved feed roll. Since the feed length of the wire is set longer than necessary, the fed wire hits the stopper which has been set at a position where the wire is fed to the necessary length. The reactive force this generates acts as a vibrating shock load upon the am lutch. It is therefore necessary to consider this when selecting a am lutch. (5) indexing applications with: spee hange (feed frequency: n = up to 300 times/m) (feed angle: 0 = up to 90 ; n 0 = 20,000 max.) In an intermittent feed mechanism that uses one or more am lutches, the speed of the driven side is changed steplessly by changing the feed angle. igure 20 below shows an example of a manure spreader. The amount of manure to be sprinkled varies depending on the field conditions. The chain conveyor is driven by an intermittent am lutch feeding action and the manure loaded on the cart is fed in bits to the continuously rotating sprinkling vanes. The manure to be sprinkled can thus be kept at the optimum amount by adjusting the amount of manure to be fed. The feed amount (or angle of the am lutch) can be controlled steplessly while the sprinkler is operating.

In a two speed drive system, it is common to operate at two different speeds; high speed and low speed. Normally, each drive system utilizes a am lutch that acts as an automatic switching device. In igure 22, when the driven unit is propelled by riving Unit (in the direction of the arrow), am lutch engages to transmit torque from the outer race to the inner race, resulting in rotation at a pre-set speed. t the same time, since the inner race of am lutch is also rotating in the same direction, it does not engage but overruns. The end result is riving Unit is disconnected from the riven Unit. onversely, when the riven Unit is to be propelled by riving Unit, am lutch engages to transmit torque of the outer race to the inner race, resulting in rotation of the riven Unit at a pre-set speed. t this time, am lutch overruns to disconnect riving Unit. riving unit Outer race Inner race am riven unit Outer race Inner race am riving unit formula a: T = J O N 2 + T T: oaded torque on am lutch (Nm) J: Inertia of load (kgf m 2 ) on am lutch shaft 0: eeding angle (deg) on am lutch shaft N: Indexing cycles per minute (c/min) T: rake torque calculated on am lutch shaft (Nm) onversion factors for above calculations 1 Nm = lb.ft. 1 lb ft. = Nm 1 kg m 2 = lb ft 2 1 lb ft 2 = kg m 2 1 kw = 1.34 hp 1 hp = 0.75 kw formula b: T = 95 kw l2 x 2.5 n l1 T: oaded torque on am lutch (Nm) kw: Transmitted power (kw) n: Speed of crank shaft (r/min) l1: ength of crank l2: ength of lever on am lutch 2.5: actor riving unit am clutch igure 22: ual Speed rive System with Overrunning am lutch Overrunning am lutch applications are divided into four types as depicted below.

When driving a fan, cement kiln or conveyor in normal operation, the driving speed is switched to high speed. When using them for other purposes, the driving speed is switched to medium or example of energy saving drive for a soaking pit fan low speed. Hydraulic Turbine Turbine Reducer am lutch igure 23: Typical High-Speed Overrunning pplication This example shows a high-speed system in which a fan is driven by a dual drive system consisting of a motor and a turbine. The am lutches are used for automatic switching between the driving units. The fan is normally driven by the am lutch on the turbine side. When starting, or when steam pressure to the turbine drops, the motor takes over from the turbine to drive the fan. am lutch engages when the turbine drives the fan, and it overruns when the motor drives the fan. onversely, am example of energy saving pump (power recovery system) am lutch Pump Motor igure 24: High-Speed nergy Saving pplication pplication of am lutches in an energy saving pump (power recovery system) shows how highly effective energy saving can be achieved with the aid of am lutches. The motor-driven pump discharges high-pressure liquid, which, after circulating, is used an am lutch Motor lutch overruns when the turbine drives the fan, and it engages when the motor drives the fan. The driving devices can be changed over without switching the clutch. This is because the difference in the speed of rotation between the motor and turbine turns the am lutches on and off, and the driving device rotating the fastest is connected automatically to the fan. Overrunning and engagement of the am lutches are performed continuously at speeds faster than 700 r/m Please reference igure 23. to drive a turbine. The turbine is then used to help drive the pump. If the pressure available is too low to rotate the turbine at high speed, the am lutch overruns. However, when the rotating speed of the turbine reaches the rotating speed of the motor, the am lutch engages automatically and the pump is driven by both the turbine, and the motor. Thus, power consumption equivalent to the turbine output can be saved. Since energy loss during overrunning and engagement of the am lutch is extremely small, this system produces results for pumps with an output as low as 10 hp (7.5 kw). Setup requires only installation of a am lutch and a turbine, providing a high efficiency energy recovery system with low running costs. Please reference igure 24. igure 25 shows a soak pit fan used for melting aluminum and steel ingots, with a am lutch being used for energy savings. The heating is done in two stages, one being quick heating and the other being constant heating. Switching is done automatically by a driving system. or quick heating, the fan is driven by the main motor at high speed (the am lutch is overrunning at this time). or constant heating, the fan only rotates at low speed and is driven by a geared motor (the am lutch engages and the main motor and fan rotate simultaneously). ompared to pole change motor or inverter systems, substantial equipment cost savings can be achieved and the initial equipment costs can be recovered very quickly. Typically equipment costs are recovered within one year of continuous running. This system is effective for fans from the 20 hp (15 kw) class and up.

In order to prevent excessive thermal transfer from distorting the fan shaft, an auxiliary drive system is used to keep the fans rotating slowly when the main motor shuts down. Using a am lutch at the auxiliary motor eliminates the need for manual clutch operation. Thermal expansion in the fan shaft must be absorbed through an expandable coupling. uring main motor operation, the am lutch rotates as a normal bearing, so service life is greatly extended. Please reference igure 26. This example shows a am lutch installed in the auxiliary drive system of a steam turbine. The auxiliary drive system powers the turbine at low speed through the engaged am lutch until steam pressure accelerates the turbine, releasing the am lutch. Then the cam automatically disengages and runs as a high-speed ball bearing, because there is no mechanical contact in the clutch. Please reference igure 27.

The pasting rolls are driven continuously by the main motor. uring this time, am lutch engages and am lutch overruns. When the main motor must be stopped temporarily to fix a problem, it is necessary to keep rotating the pasting rolls in order to prevent paste on the roll surface from drying. To do this, the rolls are driven by an auxiliary motor at a low speed sufficient to prevent the paste from drying (am lutch overruns, while engages). This system is also used with meat choppers and screw feeds in food processing machinery.

17 overrunning clutch selection Guide freewheeling To prevent differences in the rotating speed between the driving side and the driven side from damaging the equipment or the product, the am lutch overruns when speed differences occur. Normally, the am lutch engages to transmit torque, and it overruns to break the connection between the driving side and the driven side. In this case the am lutch overruns at a speed equal to the difference in rotating speed that occurs when the driven unit (normally the inner race) rotates faster than the driving unit (normally the outer race), or when the driving unit is decelerated or stopped abruptly. When feeding hoop-shaped material or plate material to the next process by slitter or pressure rolls, the material is fed at first by pinch rolls up to the main rolls. Since the main rolls process the material while pulling it at a speed faster than that of the pinch rolls, the pinch rolls are pulled by the material. t this point, the am lutch starts to overrun and prevents the pinch rolls from being driven in reverse by the material. The am lutch is used to prevent damage to the pinch roll driving parts and to the material, due to slippage between the pinch rolls. This method is also used with drying machines, engine testers, and plywood fabricating machines. Please reference igure 29.

The handle does not rotate and cause a safety hazard. am lutches are often used on the manual handles of circular knitting machines. The manual handle is used to position the machine on start-up and adjustment of the needle and thread. When the machine starts the linkage between the am lutch and the handle is broken. nother am lutch is provided at the output section of the worm reduction gears, to break the connection with the driving side during manual operation. igure 30.

18 overrunning clutch selection Guide overrunning: normal engagement reverse overrunning isconnecting driver and driven elements am lutch units are often used to protect critical pump/drive equipment from being reversed upon start-up, or when overloaded. Pumps can be overloaded with stacked material on the discharge side, resulting in reverse rotation. To prevent these damaging conditions from occurring, a am lutch is installed between the pump and the motor. In this application, the am lutch will engage to allow normal pump operation, and overrun to prevent reverse rotation. Please reference igure 31 for a depiction. isconnection of driven side igure 32 depicts an application in which the hose drum of a pipe flusher is being driven. When the hydraulic motor is rotated in reverse in the counterclockwise direction, the am lutch inner race rotates in reverse, and the am lutch overruns. The flushing pump is driven in this state. The flushing water passes through the hose and gushes out of the nozzle toward the back. The force of this water jet starts the nozzle running and pulls and unwinds the hose. t the same time, the hose drum starts reverse rotation in the same counter-clockwise direction, and increases its speed of rotation until it reaches the overrunning speed of the inner race. t this point, the am lutch engages, and the hydraulic motor works as a brake to stop the acceleration of the drum. Therefore, the running speed of the water jet nozzle is kept constant. When the hydraulic motor is rotated normally in the clockwise direction, the am lutch engages to wind the unwound hose onto the drum.

22 How To order Tfs series am luth TS Series am lutch is a sprag type clutch designed for press fit installation. Sprag type designs typically have a higher torque capacity than a similarly sized ramp & roller type clutch. TS has two vertical keyways on the outer race to assist with locating. Outside dimensions are the same as Series 63 ball bearings. This design is ideal for general inner or outer race overrunning applications. Since the TS Series does not include an integral bearing, installing the TS am lutch next to a bearing which handles both the axial and radial loads is the typical application.

40 How To order br-ht series am luth Q-R br-ht series am luth R-HT is mainly used in backstop applications as an integral part of a gear reducer. Prevention of reverse rotation for inclined conveyor and bucket elevator are typical application examples. R-HT assures not only the immediate backstop function under high torque, but also long service life by the lift-off design. In addition, installation on the high speed shaft with low torque enables selection of more compact models with resulting lower cost. example how To order ode: br-ht series am lutch R 40 HT - R66-35 Series Size escriptor - ross - ore br: High speed overrunning backstop clutch 40: Size of the am lutch R-HT Series has sizes available from 15 thru 300 ht: escriptor for high torque capacity Service ife of R-HT Series The service life of previous TSUKI am lutch models was determined as the frictional service life during freerunning (when the clutch was disengaged) and the fatigue service life of the engaged clutch. However, with R-HT Series, frictional service life is not a factor because there is no mechanical contact when the clutch is disengaged. s a result, service life is determined solely by the fatigue life of the engaged clutch. - r66b: Provides interchange information plus description of the cam cage width The "" is an internal Tsubaki designator for the width of the cam ree-running r/m 0 (a) ontact time Non-contact range ontact time ree-running time - Non-contact time 35: 35 mm bore diameter or each size within a given R Series am lutch, multiple bore diameters are available (b) ontact time riction in the clutch mechanism only occurs during a very short period of time denoted by a and b. a is the time during which the cam is engaged until the acceleration of inner race causes it to disengage. b is the time during which the cam engages when the inner race decelerates. ore Size mm T.. lb.ft (Nm) G H m M max.

43 How To order bs-hs series am luth S-HS Series am lutch offers a higher strength/higher rpm option. Non-rollover cams are flanked by individual bearings on both sides. This series is identified by "HS" following the frame size number. esigned to provide inner race overrunning capability in one direction of operation, and engage the outer race when reverse rotation is experienced. Typically found on long incline conveyor systems, bucket elevators, and large pumping systems. S-HS Series am lutch units are all manufactured on a made-to-order basis. When ordering, please specify bore size and keyway dimensions along with tolerances if available. Tsubaki includes the shaft key with your S-HS am lutch. If tolerances are not known, Tsubaki will produce per our standards. complete am lutch assembly typically includes the am lutch, torque arm, shaft key, shaft end plate, and safety cover or oil reservoir.

44 How To order bs series am luth S Series am lutch products are designed to provide inner race overrunning capability in one direction of operation, and engage the outer race when reverse rotation is experienced. S Series units are often found on incline conveyor systems, or pump systems that may experience reverse rotation due to excessive loading on the discharge side of the pump. S Series am lutches are a cam and roller design incorporating the low friction bearing into the cam cage. complete am lutch assembly typically includes the am lutch, torque arm, shaft key, shaft end plate, and safety cover or oil reservoir. The shaft key is included with the am lutch but please select each additional item individually as needed. Grease lubrication is standard for S30 through S3 am lutches. Size S425 and S4 use oil lubrication. how To order: or the S Series am lutch that is needed, please specify the series, frame size, and bore size. If the bore size needed is not specified or if different key dimensions are required, please contact Tsubaki. Made-to-order am lutches are readily available.

58 calculated Wear ife life of am luth Regarding am lutch life, there are two conditions that have a major impact. These are listed below. When assessing the expected lifetime of the am lutch it is important to consider these in relation to the actual application: 1. Overrunning abrasion (wear) life 2. ngagement fatigue life When assessing the expected lifetime of the am lutch, it is important to consider the above conditions in relation to the actual application. Overrunning abrasion (wear) life *When the am lutch overruns: On the contact surfaces of cams and races, skids occur in direct proportion to the overrunning rotational speed. Therefore it is important to pay particular attention to abrasions at the contact points. s the contact pressure by the weak spring force is low, with sufficient lubrication, these parts will not wear or abrade in a short time. Though it may vary depending on the lubricating condition, the right graph shows the calculated abrasion life, which has been properly lubricated based on the instructions provided in the catalog. brasion life must be verified especially for applications involving high speed and long overrunning periods. Outer race am Inner race Time Variable oad Graph variable load graph life of breu/br-ht series am luth The service life of previous TSUKI am lutch was determined as the frictional service life during free-running (clutch disengaged) and the fatigue service life of the engaged clutch. However, with the R Series, free-running frictional service life is not a factor because there is no mechanical contact when the clutch is disengaged. s a result, service life is determined solely by the fatigue life of the engaged clutch. ree-running r/m 0 (a) ontact time Non-contact range ontact time ree-running time Non-contact time (b) ontact time riction in the clutch mechanism only occurs during a very short period of time denoted by a and b. a is the time during which the cam is engaged until the acceleration of inner race causes it to disengage. b is the time during which the cam engages when the inner race decelerates. ngagement fatigue life *When the am lutch engages: t the contact surfaces of cams and races, the compression stress occurs in direct proportion to engagement torque. ontact surface of inner/ outer races move infinitely with respect to each engagement, while that of the cams are almost stable. Therefore, the fatigue caused by this stress will then result in the surface pitting of cams. Refer to the fatigue life curve, and check the expected life. Note: In cases where the load applied to the am lutch changes, or where vibrational loads are encountered, repeated torque loads can be applied during a single clutch engagement. The Variable oad Graph shows the type of repetitive torque loads which can be applied to the am lutch in these cases. Repeated torque loads during a single clutch engagement can have the effect of increasing the overall torque load, and this must also be considered when determining am lutch service life. fatigue service life graph Outer race am Oil film Inner race
