4 Fenner rives Keyless ushings From the moment the wheel came into existence, man has been face with the seemingly simple task of mounting his invention to a shaft so that something useful coul be accomplishe. Though it has been over 5,500 years since these rotating components have mae their way into use, many esigns still utilize mounting methos not much improve from the ays of antiquity. These traitional connection methos inclue: interference fits (shrink or press), keys an keyways, splines an quick etachable bushings. In the sections that follow, we compare an contrast these component mounting techniques an explain the principles behin the ingenious Fenner rives Keyless ushing. Traitional Connection Methos Interference Fits (Shrink an Press) shrink fit is a proceure whereby heat is use to facilitate a mechanical interference fit between two pieces of metal, such as a steel shaft an hub. Extreme heat is applie to the hub, causing it to expan an increasing the size of its machine bore. The expane hub is remove from the heat source an quickly positione onto the shaft. s the hub cools, its bore contracts back to its original machine imension, effectively shrinking the hub onto the shaft. Shrink/Press press fit achieves the same en as a shrink fit a mechanical interference fit between a steel shaft an hub but oes so through ifferent means. Press fits rely on the application of simple brute force to press the hub onto the shaft. Interference fits offer several avantages, such as zero backlash an uniform fit pressures, but these avantages come at a price. High capacity interference fits require long fit lengths, close tolerances, expensive an sometimes hazarous heat sources or hyraulic presses, an fiel maintenance is extremely ifficult. Finally, separate components can rarely be re-use. Keys, Keyways & Splines The centuries-ol inustry stanar shaft-to-hub mounting technique is the key an keyway. While ubiquitous an intuitively easy to unerstan, the key an keyway is a remarkably ineffective technology. Machining a keyway into a shaft is not inexpensive, nor is the equipment require to o so, though these costs are often unknown or overlooke. Keyways introuce notch factors, which account for the reuce effective cross section an abrige fatigue life that occurs when a shaft is keye an lea, in turn, to systematic over-sizing of shaft iameters. This translates to more shaft material an weight, larger bearings an other rive components, an increase cost. Further, keye connections require fit clearance for assembly, both between key an keyway an between shaft an hub. Key & Keyway The combine effect of these clearances is backlash. In applications with frequent starts/stops, irection changes, an/or shock overloas, this backlash can lea to poune out keyways, fatigue failures, fretting corrosion or some combination of these failure moes. Nor o keys an keyways len themselves to motion control applications, since backlash eroes the accuracy of motion profiles over time. spline connection is simply a series of keys an keyways that suffers the same limitations an rawbacks associate with a single keye connection. Manufacturing costs are high, especially on hollow shafts, an special surface treatment is often require to increase strength. Spline Keye ushing Systems oth Q an Taper-ock bushing an wel-on hub systems are popular component mounting technologies, especially in North merica. Yet both are ultimately keye connections an as a result suffer from the same operational rawbacks as escribe above. s their name inicates, the wel-on hubs require an aitional, an expensive, manufacturing step. n while the bushings can be use without a wel-on hub, oing so requires machining a taper an rilling an tapping holes in the mating part. Taper-ock Q 4

5 Why Go Keyless Toay s global marketplace emans precise, efficient machines that optimize prouctivity while minimizing material an fabrication costs. When compare to traitional connection methos, Fenner rives Keyless ushings offer the following avantages: mechanical interference fit with a uniform pressure istribution similar to that achieve through a shrink or press fit. true zero backlash shaft-to-hub connection with none of the operational rawbacks of keyways or splines. The ability to mount on plain shafting, which nee not be over-size to compensate for notch factors. This allows the use of smaller shafts an bearings for more cost effective esigns. Trantorque The flexibility to mount over existing keyways if esire. Straight bore machining of the mounte component, generous machining tolerances an as-turne surface finishes. Complete axial an raial ajustability. Simple installation, ajustment an removal, even in the fiel. Principles of Operation Though offere in many shapes an sizes, Fenner rives Trantorque Keyless ushings all operate using the simple wege principle. n axial force is applie by the hex nut to engage circular steel rings with mating tapers.the resulting wege action creates a raial force on the tapere rings, one of which then contracts to squeeze the shaft while the other expans an presses into the component bore. The prouct of the raial force applie to the shaft, the raius of that shaft an the coefficient of friction between the surfaces being joine equals the rate torque capacity of the connection.

9 Keyless ushings Engineering Information SURFCE FINISH Recommene surface finish for shafts an hub bores to be use with Fenner rives Keyless ushings is between.8 an 3.1 micro-meters RMS. smoother finish such as that foun on components supplie TG&P (turne, groun an polishe) is NOT recommene an can result in a failure of the connection. Note that surface finishes below.8 micro-meters RMS can be roughene using longituinal abrasion with a bastar file, emery paper or similar to achieve a surface finish within the recommene range. CONCENTRICITY Fenner rives Keyless ushings are precision machine to maximize concentricity an minimize runout. The final installe concentricity of mounte components epens on several variables, incluing the components themselves an the installation technique employe. Overall, concentricity is typically excellent for Fenner rives Keyless ushings. SYNTHETIC RIVE COMPONENTS Fenner rives Keyless ushings are not recommene for use with most rive components constructe of synthetic polymers. n exception can be mae if the component incorporates a reinforcing metal sleeve of sufficient size an strength. Please consult a Fenner rives pplications Engineer regaring such applications. TEMPERTURE INFUENCE Similar to conventional shrink or press fits, connections using Fenner rives Keyless ushings are not affecte by temperature changes as long as they apply equally to shaft an mating hub. Since temperatures above 204 C lower the strength of most commonly use materials, special consierations are necessary for connections working in temperatures exceeing 204 C. MOUNTING ERINGS WITH FENNER RIVES KEYESS USHINGS Mounting bearings with a Fenner rives Keyless ushing is not recommene. The expansion forces generate will istort the bearing s inner race, causing premature failure. URICNTS Trantorque OE an OE Mini Series are supplie unplate an lightly coate with orinary machine oil. ll other Trantorque units are supplie free of lubricant. MTERIS Trantorque Keyless ushings are manufacture from carbon steel. For applications in corrosive environments, corrosion resistance can be improve through sealing with grease or silicone, the use of protective cover plates, application of inustry stanar plating materials (e.g., nickel, thin ense chromium, etc.) or by specifying the prouct in stainless steel (such as Trantorque SS) or other corrosion resistant materials. Please consult with a Fenner rives pplications Engineer for more etails. TORQUE T = peak rive torque = nominal torque multiplie by a variable safety factor to account for stall or start-up conitions, mass accelerations, impact loas, etc. Nominal rive torque can be calculate as follows: M tnom = 9550 kw rpm Consult with a Fenner rives pplications Engineer in cases where T is uncertain. M t = The rate torque capacity of one Fenner rives Keyless ushing installe accoring to our instructions. Publishe torque capacities are calculate without using a safety factor an shoul be consiere as the point where a connection coul slip if a higher torque is applie. Therefore, always select a unit where M t T. MOIFIE INSTTION TORQUE capacity an contact pressures is a linear function of hex nut tightening torque (M a ) an can be ajuste if necessary by reucing M a up to 20%. NEROIC HESIVES (THREOCKER) o not use anaerobic ahesives such as octite, Permatex or similar compouns with Fenner rives Keyless ushings. oing so results in unknown contact pressures an capacities. Further, isassembly may be compromise when such compouns are applie to the keyless bushing, the shaft an/or the hub bore. Proper installation assures sufficient pre-loa so that threas are self-locking, even in cases where the keyless bushing is subjecte to extreme vibratory conitions. HOOW SHFTS Hollow shafts with bores exceeing 35% of outsie iameter usually require a reuction of contact pressures in orer to avoi permanent shaft eformation. Special consierations arise when installing Fenner rives Keyless ushings onto hollow shafts. Please consult with a Fenner rives pplications Engineer for a trouble free hollow shaft connection.

ENING MOMENTS ening moments are a crucial sizing factor in applications where a raial loa from chain pull, the weight of components, etc., acts significantly outsie the keyless bushing centerline. Typical applications inclue rolls or conveyor pulleys where shaft eflection ue to raial loas results in a bening moment between shaft an en isc. Generally, bening moments change from a positive to a negative value uring each rotation an are esignate as rotating or reversing bening moments. Fenner rives Keyless ushings are well suite to transmit rotating/reversing bening moments. Compile using relevant ata gleane from numerous successful heavy-uty applications in conveyor pulleys as well as pertinent investigations by inepenent institutions, 0.28 M t bening moment capacity applies. where: M t = Rate torque capacity (from specification tables) Consult with a Fenner rives pplications Engineer on applications where the actual bening moment excees these recommene limits. RI OS Raial loas are generate when force is applie perpenicular to the centerline of the shaft an are frequently associate with pin or axle connections (see illustration below). Fenner rives Keyless ushings are well suite to provie tight, backlash-free connections for this type of application, as explaine below. F ra = raial loa capacity = P s where: = shaft iameter = hub bore = contact length P h = hub pressure P s = shaft contact pressure = P h Typical pressure istribution in backlash-free pin connections = pin iameter oa p min. = p - p 0 p max. = p + p Y.P. Explanations: p = contact pressure provie by keyless bushing p = contact pressure on projecte contact area = loa x contact length Y.P. = yiel point of pin material TORQUE N ENING COMINE Simultaneous transmission of torque an bening requires calculating a resultant torque: M tb = T 2 + (2 M b ) 2 where: T = peak rive torque M b = bening moment lways select a unit where M t M tres an M tb is within the limits appearing uner ening Moments above.

11 HU SIZING Fenner rives Keyless ushings transmit torque an other loas by means of mechanical interference generate by pressure exerte on both the shaft an mounte component hub. Therefore, consieration must be given to the amount of hub material (wall thickness) require to prevent permanent expansion (i.e., yieling). The following information is provie to assist you in etermining the require hub iameter N for any keyless bushing application. From the stress equations presente below, the require hub iameter N is etermine as follows: N = Y.P. + (P h C) Y.P. - (P h C) where: = hub bore iameter (from prouct specifications) P h = contact pressure applie to hub bore (from prouct specifications) Y.P. = tensile yiel point of your hub material n C is a Stress Reuction Factor which assumes the value of 1.0 or 0.8 epening upon the relationship of your actual hub with H w to the contact length of the keyless bushing selecte.
