4 Sure-lex Capabilities 4-WY LEXING CTION absorbs all types of shock, vibration and misalignment TORSIONL Sure-lex coupling sleeves have an exceptional ability to absorb torsional shock and dampen torsional vibrations. The EPM and Neoprene sleeves wind-up approxi mately 15 torsionally at their rated torque. Hytrel sleeves will wind-up about 7. NGULR The unique design of the Sure-lex coupling s teeth allows for the absorption of angular misalignment without wear. Refer to page 1 18 for actual allowable misalignment limits. These limits allow for the alignment of the coupling using only a scale and calipers. PRLLEL Parallel misalignment is absorbed without wear or appreciable energy losses. The lateral flexibility of the coupling sleeve minimizes radial bearing loads normally asso ciated with parallel misalignment. This feature also allows for easier installation by the use of components bored for slip fits without fretting corrosion occurring at the shaft. Refer to page 1 18 for parallel misalignment limits. Only a straight-edge and feeler gage are required to obtain these limits. XIL Sure-lex couplings may be used in applications with limited axial shaft movements. The axial compressibility of the EPM and Neoprene sleeves allows for shaft end-float without the absolute transfer of thrust loads. 1-2 T Wood s P-1686-TW 2/14

5 Sure-lex eatures ESY, QUICK INSTLLTION Sure-lex can be installed quickly and easily, because there are no bolts, gaskets, covers or seals. lignment can be checked with a straightedge placed across the outside of the precision-machined flanges. No special tools are needed for installation, alignment or removal. NO LURICTION, TROULE-REE OPERTION The teeth of the sleeve lock into the teeth of the flanges without clamps or screws, tightening under torque to provide smooth transmission of power. There is no rubbing action of metal against rubber to cause wear. Couplings are not affected by abrasives, dirt, or moisture. This eliminates the need for lubrication or maintenance, provides clean, dependable, quiet performance. Sure-lex couplings are selected as component parts. 1. etermine SLEEVE material and type.

Load Symbol L Light M Medium H Heavy Standard C Motor C Shunt Motor *Engine, 8 or more cylinders High Torque C Motor C Series & Comp *Engine, 4-6 cylinders *Engine, 3 cylinders or less Turbine *On applications involving varying torque loads, design around the maximum load. Then determine the resulting service factor at minimum load. If this value is greater than 4.0, special coupling alignment will be required (see page 1 18). Caution: pplications involving reciprocating engines and reciprocating driven devices are subject to rotational vibrational critical speeds which may destroy the coupling. The factory can determine these speeds when the rotational inertia (WR 2 ) of the driver and driven units is known. 1-6 T Wood s P-1686-TW 2/14

9 Sure-lex Coupling Selection 3. If coupling to the shaft of a 60 HZ C motor, you may refer to page 8, locate the correct chart & columns for your sleeve material, motor speed and service factor; you can read the coupling size across from the motor horsepower. Example: or RPM and 1.5 Service actor - Use #13 EPM or Neoprene or #10 Hytrel or Urethane. 4. or other speeds, use the following formula to calculate the required coupling horsepower 100 rpm. 100 rpm = HP x Service actor x 100 / coupling RPM 5. Use the chart below to find a coupling with a 100 RPM rating which is greater than calculated above. Example: or 5 55 RPM and 1.25 Service actor: 100 = 5 x 1.25 x 100 / 55 = Use #12 EPM or Neoprene or #9 Hytrel with rating of 11.4 HP. * Urethane values are , , and COUPLING RTINGS Size EPM Neoprene RPM Torque Stiffness Max Sleeves Sleeves (in. lbs.)

11 Type J Sure-lex TS or Close Coupled pplications T C E H LNGES Type J flanges sizes 3.4 and 5 are manufactured of sintered carbon steel. The powdered metal manufacturing process provides high dimensional accuracy and uniform material properties for high strength. Size 6 is made of high strength cast iron. ll flanges are bored-to-size for a slip fit on standard shafts. The outside diameter of the flange is machined so the surface can be used to check alignment without a special tool. Type J flanges can be used with sleeves of any construction except the Hytrel. Each flange has a keyseat and one (1) setscrew over the keyway. ll have a setscrew at 90 from the keyway. L G COUPLINGS Type J Sure-lex Couplings are bored-to-size. Normally, they em ploy the one-piece JE sleeve, or the one-piece JES sleeve with saw cut to permit replacement where there is insufficient gap between shafts. Spacing between internal flange hubs equals G. Spacing between shafts should be greater than 1/8 in. and less than L minus.85 times the sum of the two bore diameters.

19 Type C Sure-lex imensions CLMP HU SPCER ESIGN C E LNGES H Sure-lex Type C Clamp Hub flanges employ integral locking collars and screws to assure a clamp fit on the shaft. One setscrew is furnished over the key. They are designed primarily for applications where flanges must be removed from one or both shafts without moving either the driver or driven units. typical application is a screw compressor which uses a replaceable face seal around the input shaft. COUPLINGS L G Type C Clamp Hub Couplings normally use Hytrel sleeves. However, any of the sleeves shown on page 1 5 can be used. Type C couplings may often be used where spacer couplings are required. Spacing between internal flange hubs equals G.

20 Sure-lex Couplings Installation Instructions Installation Instructions Sure-lex flanges (outer metallic parts) and sleeves (inner elastomeric members) come in many sizes and types. irst, determine the size and type of components being used. Remove all components from their boxes, and loosely assemble the coupling on any convenient surface. (o not attempt to install the wire ring on the two-piece E or N sleeve at this time.) lso check maximum RPM values in the table against operating speed. ll rubber sleeves (EPM and Neoprene) have the same ratings for a given size and may be used interchangeably. However, because rubber and Hytrel sleeves have completely different ratings, they never should be used interchangeably. Inspect all coupling components and remove any protective 1 coatings or lubricants from bores, mating surfaces and fasteners. Remove any existing burrs, etc. from the shafts. 2 Slide one coupling flange onto each shaft, using snugfitting keys where required. When using Type flanges, follow the instructions furnished with the Sure-Grip bushing. Position the flanges on the shafts to approximately achieve 3 the Y dimension shown in the table. It is usually best to have an equal length of shaft extending into each flange. Move one flange to its final position. Torque fasteners to proper values. Slide the other flange far enough away to install the sleeve.with a two-piece sleeve, do not move the wire ring to its final position; allow it to hang loosely in the groove adjacent to the teeth. 6 Check angular alignment with a micrometer or caliper. Measure from the outside of one flange to the outside of the other at intervals around the periphery of the coupling. etermine the maximum and minimum dimensions without rotating the coupling. The difference between the maximum and minimum must not exceed the figure given under ngular in the table. If a correction is necessary, be sure to recheck the parallel alignment. Sleeve Size Parallel ngular MXIMUM RPM N LLOWLE MISLIGNMENT (imensions in inches) Maximum RPM Types JE, JN, JES, JNS, E & N *Type H, HS, Urethane Parallel ngular Y Parallel ngular Y Y Slide the loose flange on the shaft until the sleeve is completely seated in the teeth of each flange. (The Y dimension is for reference and not critical.) Secure the flange to the shaft. ifferent coupling sleeves require different degrees of alignment precision. Locate the alignment values for your sleeve size and type in the table. Check parallel alignment by placing a straight-edge across 5 the two coupling flanges and measuring the maximum offset at various points around the periphery of the coupling without rotating the coupling. If the maximum offset exceeds the figure shown under Parallel in the table, realign the shafts Note: Values shown above apply if the actual torque transmitted is more than 1/4 the coupling rating. or lesser torque, reduce the above values by 1/2. *Type H and HS sleeves should not be used as direct replacements for EPM or Neoprene sleeves. 7 If the coupling employs the two-piece sleeve with the wire ring, force the ring into its groove in the center of the sleeve. It may be necessary to pry the ring into position with a blunt screwdriver. 8 Install coupling guards per OSH requirements. CUTION: Coupling sleeves may be thrown from the coupling assembly with substantial force when the coupling is subjected to a severe shock load or abuse T Wood s P-1686-TW 2/14

40 G-lex Grid Couplings eatures Principal of Operation Positive protection against the damaging effects of shock loads, impact loads and vibration. The grid is torsionally flexible. The circumferential flexibility is progressive due to the curved profile of the grooves state-of-the-art in resilient coupling design. ccommodating Shaft Misalignment and End-loat The grid will accommodate combinations of misalignments present at set-up or occurring during machine displacement, settlement, etc. Limited End-loat kits are available on request. Effectiveness of Torsional amping Parallel ngular End-loat s the grid coupling transmits torque, the flexing of the tapered grid spring damps vibrations and cushions shock loads. This unique characteristic is due to the torsional flexibility of the coupling being proportionate to the unsupported length of each flexible grid rung. The resultant reduction in peak loading protects and extends the life of the transmission equipment. Versatile esign mplitude of shock Transmission shock without grid coupling Transmission shock with grid coupling oth 1000T10 and 1000T20 couplings feature identical hubs and grid springs, the different cover styles provide great versatility one is horizontally split T10, the other is vertically split T20. ll coupling components are designed to be interchangeable with other taper grid couplings. The stock coupling can be used vertically or horizontally without modification. Easy Installation and Maintenance The grid springs are easily installed by hand or with a soft mallet. The cover fasteners can be tightened with standard wrenches. Every T Wood s coupling is delivered with detailed installation instructions. Periodic Lubrication of the coupling is required and each cover half is supplied with standard plugs which can be easily removed for re-lubrication. Recommended its between Shafts and Hubs Coupling bore tolerances for sizes up to and including 1090T can be specified to suit a clearance fit with the shaft. In these instances the hub is provided with set screws. Relative positions are given in the following table. S Position from Hub aces 1020 = = = = = = = = 2.8 or sizes above 1090T or where interference fits are preferred for smaller coupling sizes, bore tolerances will be consistent with GM standards.

41 Taper Grid Resilient Couplings Series 1000T10 nd Series 1000T20 r. James ibby originally invented the Resilient Coupling in 1917 and the 1000 Series is the latest level of this well accepted product. This ibby Turboflex product has become universally accepted where reliable protection against shaft misalignment and vibration is desirable. Since those early days refinements in design and material specifications have kept pace with advancing technology, achieving significant improvements in power/weight ratios. T Woods is proud to offer this proven product. 1000T10 Horizontally Split Cover General Purpose Easy access to grid minimizes downtime Ideal for limited space applications Stop lug in cover prevents spinning during reversing service 1000T20 Vertically Split Cover General purpose Ideal for higher running speeds High Performance The T Wood s Taper Grid Coupling continues that tradition. The tapered grid is made from high tensile alloy steel which is carefully formed to the grid shape before hardening and tempering under controlled conditions. The grid surface is then shot-peened. This process leaves the grid spring with a residually stressed surface layer which is in compression and which impedes the propagation of cracks. Since nearly all fatigue and stress corrosion failures originate at the surface of a part, the layer of compressive stress induced by shot-peening produces a dramatic increase in the working life and fatigue strength of the grid. This technological improvement in manufacturing process coupled with precise monitoring of raw material specification and control of trapezoidal shape, permits T Wood s to offer state of the art grid springs of high performance and reliability. Scientific esign The hub is precision manufactured from high quality materials, with the hub tooth profile scientifically designed to permit progressive loading under torsional shock conditions. The combination of tapered grid and precision manufactured hub provides easy assembly. The excellent shock absorption characteristics, and the ability to accommodate misalignment protects the connected equipment. Long Life While the coupling is designed for long life under tough conditions, maintenance and taper grid replacement can be performed quickly and easily without the need to move and realign connected equipment. Two cover design options are available in the T Wood s range of couplings. oth designs have been carefully engineered to provide a shaft coupling which is highly reliable and easy to install.

The asic flex coupling consists of two hubs, a spacer and two flexible discs. The flex disc is an assembly of thin metal laminations. In figure shown below, flex disc holes & C are bolted to the hub and holes & are bolted to the spacer. Torque is transmitted in direct tensions from to and from C to through the flex disc. Misalignment is taken through bending in the link between the bolt holes.

YNMIC LNCING RECOMMENTIONS Use this graph to determine the appropriate balance class based on coupling weight and operating speed. The balance classes listed on the graph are for equipment with average sensitivity to coupling unbalance. The user should determine how sensitive the equipment train is to coupling unbalance. Use one balance class higher if your system has higher than average sensitivity to unbalance. Use one balance class lower if your system has lower than average sensitivity to unbalance. Use this guide to check your coupling selection against the recommended balance class for your operating conditions. The following factors should be considered when determining a machine s sensitivity to coupling unbalance. 1) Shaft End eflection: Machines having flexible shaft extensions are relatively sensitive to coupling unbalance. 2) earing Load ue to Coupling Weight Relative to Total earing Load: Machines having lightly loaded bearings, bearings that are primarily loaded by the weight of the coupling or other overhung weight are relatively sensitive to coupling unbalance. 3) earing, earing Support and oundation lexibility: Machines or systems with flexible foundations for supports for the rotating elements are relatively sensitive to coupling unbalance. 4) System Natural requencies: Machines operating at or near natural frequencies are sensitive to coupling unbalance. 5) Machine Separation: System having widely separated machines are relatively sensitive to coupling unbalance. 6) Shaft Extension Relative to earing Span: Machines having a short bearing span relative to their shaft extensions are sensitive to static unbalance.

Single flexing couplings may only be used to accommodate angular and axial misalignment. metal disc type coupling uses a double hinge effect through two flexible discs and the spacer to compensate for parallel offset misalignment between shafts. Parallel misalignment imposes the same angular deflection () on each flex disc. ngular misalignment of either connected shaft, (), creates additional angular deflections which are added to the angular offset due to parallel misalignment. The total misalignment angle, (C), at the flex disc is equal to the angular offset due to parallel misalignment () plus the angular offset due to angular misalignment (). The maximum misalignment angle (C) should never exceed the rated misalignment capacity of the coupling type being used. Machinery equipment changes in actual operation and over the life of the equipment. We recommend that the machinery misalignment be set as close to zero as possible when a coupling is installed. We recommend keeping the measured misalignment below 25% of the rated misalignment capacity of the coupling type used when the machinery is installed and aligned. The remaining coupling misalignment capacity will then be available to accommodate additional misalignment caused by foundation shifts, vibrations, thermal growth or other causes.

77 True Tube Composite Torque Tubes imensions True-Tube composite tubes are high-strength, lightweight torque tubes for long span drive shafts. These tubes are filament wound carbon or glass fiber construction in an oven cured epoxy matrix. True-Tube composites offer the following advantages over steel tubing. LONGER SPNS TrueTube composite tubes have a higher stiffness to weight ratio than steel tubing. That increases the critical speed of the tubing and allows longer spans without center bearings. LIGHT WEIGHT TrueTube drive shafts weigh up to 80% less than equivalent steel driveshafts. That means better balance and reduced vibration. earing life may be improved by minimizing overhung weight. ESIGN LEXIILITY TrueTube composite tubes may be custom designed to meet your requirements for Torsional Stiffness, critical speed or torque capacity. With TrueTube, a designer can tune torsional or lateral critical speeds out of a machine system. ll TrueTube products include an ultraviolet barrier that is wound into the structure of the tube before it is cured. This UV barrier eliminates the need for paints or other protective coatings and results in a smooth, durable finish that other composite tubes don t offer. TrueTube products are cured in an enclosed oven to assure consistent strength and quality. esign data is shown below for standard series tubes. Standard series tubes are designed for maximum length at moderate torques. High torque designs are also available. MOEL NUMER TUE I.. INCHES TUE O.. INCHES SLEEVE O..
