1 KEYESS FRICTIONA SHAFT/HUB OCKING EVICES THE KEY TO BETTER MACHINE ESIGN IS NO KEY AT A. CATAOG C02

2 INTROUCTION: THE PROBEM: In a typical keye shaft/hub connection, the clearance between key an keyway require for fitting is a serious isavantage when shock or reversing loas are to be transmitte. Any component hel by a key is slipping on the shaft at start-up or loa reversal by an amount equal to the amount of fit clearance. This results in impact loas when contact with the key stops the slippage. These impact loas, which are rarely accounte for in the esign process, generate a continuous pouning between key an keyway. This pouning, combine with fretting corrosion cause by micromovements at the fit interface, frequently leas to shaft failures like the ones illustrate above. [Shaft failure illustrations are reprouce with permission of Sachs, Salvetera & Associates, Solvay, NY.] TRAITIONA INTERFERENCE FITS: The solution to these problems is elimination of the key by using a frictional bon between components an shafts. This type of connection, commonly known as an interference (shrink or press) fit, results in zero clearance hence, no backlash an utilizes the full contact area for uniform transmittal of torques an/or bening moments. Such a connection will never poun out even for an infinite number of loa cycles as long as the frictional holing capacity of the connection is equal to or higher than the loas applie. In aition, the elimination of keyways eliminates keye shaft notch factors, permitting smaller shaft an bearing sizes an reucing the overall cost an complexity of a esign. espite these avantages, mounting an removal problems associate with shrink or press fits have frequently isqualifie this type of connection for many applications. 2

3 THE B-OC SOUTION B-OC Keyless Frictional Shaft/Hub ocking evices provie the ultimate solution by incorporating all the avantages of interference fits, while eliminating mounting an removal problems. B-OC ocking Assemblies an Shrink iscs rely on the proven wege principle to create a keyless, mechanical interference fit by converting locking screw tension into raial contact pressures on shaft an hub. This connection, while in many ways similar to conventional shrink or press fits, has several istinct avantages: 1. In the relaxe position, B-OC keyless connectors provie a generous clearance for easy mounting an ismounting. 2. B-OC keyless connectors generate higher contact pressures than those obtaine by a shrink or press fit, thereby allowing for shorter hub lengths an eliminating the problem of fretting corrosion associate with wier connections.. B-OC keyless connectors facilitate simple axial an angular timing of hub.

AE2 AE AE Miter gear connecte with Series B1 installe over aaptor sleeve that also serves as shaft coupling. Engineere class belt conveyor pulley with avance T-shape en isc connecte to shaft with Series B5. Typical Split Shrink isc arrangement. Narrow, hightorque press gear moifie for repair using both Shrink isc an Series B1 ocking Assembly (aaptor sleeve allows use of larger ocking Assembly, increasing torque capacity of connection).

7 AE5 AE Pinion gear connection using Series B1 in application where retainer plate an aaptor sleeve permit axial ajustment of inner race of tapere roller bearing. Thin walle gear hub is reinforce with steel ring installe with light interference. Series B1 esign is similar to Series B1 but with fewer holes in front collar, higher torque capacity an/or wier contact length. AE AE Series B00 an Series B1 use in series for gear with wie hub. Relatively thin hub cross section can be reinforce with steel collar. Series B0 esign with asymmetric tapers offers heavy uty capacity at a reuce cost, but requires shaft shouler for push-off uring isassembly (can also be supplie with collars inverte). AE AE B00 use to mount B-type roller chain sprocket with relatively small hub O. Series B with outer reinforcing collar use as mounting flange for hollow-shaft hyraulic rive with quill bore that is substantially smaller than riven shaft iameter. Shrink isc use to mount mating aaptor flange to motor.

8 AE AE Selective screw tightening on opposing Series B00 units permits precise ajustment of flange pilot an axial an raial runout. Mounting of rive irectly onto riven shaft results in maintenancefree connection. See Page 1 for more information on B-OC sleeve an flange-type rigi couplings. AE AE Series applies thrust against bearing inner race uring assembly in lieu of typical arrangement using lock nut an threae shaft.

10 B-OC INTERNA EVICES: OCKING ASSEMBIES ESIGN FEATURES TORQUE B-OC ocking Assemblies are well suite to transmit torque, bening, thrust, an raial loas. Proper selection results in a zero backlash connection free of wear even uner severe reversing loas. Use the following criteria to ai in selecting the right unit for your application: 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 = 52 x HP / rpm Consult with us in cases where T is uncertain. M t = rate torque capacity of (1) B-OC ocking Assembly with all screws tightene to specifie torque M A as liste in specifications. Tabular values 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, you shoul always select a unit where M t T. Torque capacity an contact pressures are a linear function of locking screw tightening torque an may be varie if this is avantageous for certain applications by changing M A within the following limits: Series B00: Series B/B/B: Series B00: Series B1/B: Series B5: up to % higher or up to % lower up to % lower up to % lower up to 0% lower up to % lower In installations where two or more B-OC ocking Assemblies are arrange in series with access to locking screws from one sie only, total torque capacity is not a linear function of the number of units applie. In these situations, the factor f mu shoul be use to compute total torque capacity, as follows: M t total = n x M t x f mu THRUST F ax = transmissable thrust, etermine by using the following equation: x M F ax = t, where = shaft iameter (in) TORQUE AN THRUST COMBINE Simultaneous transmission of torque an thrust requires calculating a resultant torque: M tres = T 2 + (F x / 2) 2, where: T = peak rive torque (ft-lbs) F = peak thrust loa = shaft iameter (ft) Select a unit where M t M tres. BENING MOMENTS Bening moments are a crucial sizing factor in applications where a raial loa from chain pull, the weight of components, etc., acts significantly outsie the locking assembly 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. B-OC ocking Assemblies are well suite to transmit rotating/reversing bening moments. As a result of numerous successful heavy-uty applications in conveyor pulleys an pertinent investigations by inepenent institutions, the following bening moment capacities apply: Series Bening Moment Capacity B00 = 0. x M t B, B, B, B00 = 0.2 x M t B5 = 0.2 x M t B1 an B = 0.5 x M t Consult with us for applications where the bening moment capacity excees these recommene limits. Factors f mu for etermining total torque capacity in multiple unit ocking Assembly installations ocking Assembly n = number of units in series Type 2 B00 & B B5.0.5 N/A B1.5 N/A N/A B.0 N/A N/A TORQUE AN BENING COMBINE Simultaneous transmission of torque an bening requires calculating a resultant torque: M tb = T 2 + (2M b ) 2, where: T = peak rive torque (ft-lbs) M b = bening moment (ft-lbs) Select a unit where M t M tb an M b is within the limits shown above.

11 CONCENTRICITY B-OC ocking Assemblies provie goo to perfect concentricity in a variety of applications. The level of concentricity epens on taper angle an length, hub pre-centering, an moe of screw tightening. The following escription of features shoul be helpful in selecting the most suitable evice to meet specific concentricity requirements. TEMPERATURE INFUENCE Similar to conventional shrink or press fits, B-OC ocking Assembly connections are not affecte by temperature changes as long as they apply equally to hub an shaft. Since temperatures above 00 eg. F lower the strength of most commonly use materials, special consierations are necessary for connections working in temperatures higher than 00 eg. F. SERIES B00: The relatively narrow with of these ouble collar evices usually necessitates the nee for a pre-centering hub section. Type of fit as well as the length of this pre-centering section greatly influences concentricity. The use of pilot bushings permits the reuction of hub length or even the elimination of pre-centering hub sections in the case of a roll configuration. These units provie concentricity sufficient for low to meium spee components. SERIES B, B, B, B00: These ocking Assemblies o not require a pre-centering hub section. The I.., O.. an taper of these units are machine in a single set-up ensuring perfect concentricity for the locking assembly itself. Total system concentricity will epen on installe components, but is typically excellent, even for high spee applications. SERIES B5, B1, B: The goo precentering characteristics of these evices, combine with their wie ouble taper esign, provies excellent concentricity for any type of application. RAIA OAS Raial loas are generate by forces applie perpenicular to the centerline of the shaft, an are frequently associate with pin or axle connections. B-OC ocking Assemblies are well suite to provie a tight, backlash-free fit for such connections (see illustration below). F ra = raial loa capacity = x x P, where: = shaft iameter (in) = contact length (in), see spec. tables P = shaft contact pressure (psi) Typical pressure istribution in backlash-free pin connections =pin iameter HOOW SHAFTS SECURING OF OCKING SCREWS REEASABIITY MATERIA Hollow shafts with bores exceeing 5% of outsie iameter usually require a reuction of contact pressures in orer to avoi permanent shaft contraction. Consult with us for the amount of reuction require or for corrective measures available for a trouble-free hollow shaft application. Specifie locking screw tightening torque M A assures sufficient pre-loa so that screws are self-locking, even in cases where B-OC ocking Assemblies are subjecte to extreme vibratory conitions. B-OC ocking Assemblies an Shrink iscs are esigne for fast an easy removal. Our B00 ocking Assemblies, as well as all B-OC Shrink iscs, feature self-releasing tapers. All other types use self-locking tapers for a more efficient clamp loa conversion an higher bening moment capacities. For these units, a sufficient number of integrate push-off holes assure positive ismounting even after many years of service. B-OC ocking Assemblies are manufacture from heat treate high-carbon an alloy steels. Please contact us for applications requiring stainless steel. Corrosion resistance can be improve through the application of inustry stanar plating materials an/or the use of protective cover plates. oa p min. = p - p 0 Explanations: p = contact pressure provie by ocking Ass y. p = contact pressure on projecte contact area loa = x contact length Y.

The maximum wall thickness of an aaptor sleeve shoul be approximately % of the shaft iameter. The minimum thickness will epen upon the machining process. It is important to note that in orer to maximize the torque capacity of a sleeve ocking Assembly connection, the shaft/sleeve bore interface shoul be free of any lubricant, resulting in a coefficient of friction µ = 0. an making the sleeve O/ocking Assembly bore the point of lowest torque capacity (provie the sleeve O is less than 1. times the shaft iameter). This facilitates full use of the larger ocking Assembly s higher torque capacity. Notes: 1. Sleeve I = s -0/+.001 where s = shaft ia. 2. Sleeve O = +0/-T for ocking Assembly to be use.. Install RY at shaft/sleeve bore interface for coefficient of friction µ =0... Torque capacity at sleeve O = M t for ocking Assembly to be use. s 5. Torque capacity on shaft = M t x x 1...

24 HUB SIZING B-OC ocking Assemblies transmit torque an other loas by means of mechanical interference generate by pressure exerte on both the shaft an hub, meaning that consieration must be given to the amount of hub material require to prevent permanent expansion (i.e., yieling).

Using the stress equations presente at right, the require hub O " N " is etermine as follows: THICK WAE CYINER SUBJECTE TO INTERNA PRESSURE σ t σ r ο ο P i i x THICK WAE CYINER SUBJECTE TO EXTERNA PRESSURE P σ t σ r i ο ο i where = hub bore (inches) from specification tables, an... p = contact pressure (psi) applie to hub bore from H specification tables Y.P. = N = Y.P. + (p x C) H Y.P. - (p x C) yiel point (psi) of hub material (see below) C = Stress Reuction Factor, consiering the relationship of actual hub with "B" (as etermine by customer) to ocking Assembly contact length "" (per specification tables), etermine as follows (assumes locking assembly collar in contact with hub bore is centere in hub): For Series B, B, B, B00 an B00 C = 1.0 for B = C = 0. for B = 1.5 x C = 0. for B = 2.0 x For Series B1, B an B5 C = 1.0 for B = C = 0. for B = 1. x C = 0. for B = 1. x This equation can also be expresse as N =K, where Y.P. + (p x C) H K represents the expression.

26 B-OC EXTERNA EVICES: SHRINK ISCS & WK SERIES RIGI SHAFT COUPINGS ESIGN FEATURES TORQUE External locking evices for keyless frictional shaft/hub connections on shafts from 5/ to 0 iameter, B-OC Shrink iscs... Provie a high capacity interference fit with all the positive features of conventional interference fits, but without their assembly an ismounting problems. Offer extremely concentric an well-balance connections, ieal for high-spee applications. Permit simple axial an angular timing. Are available in stanar, light, an heavy-uty series to suit any application. WORKING PRINCIPE The ouble tapere inner ring of a B-OC Shrink isc provies a high-ratio conversion of screw clamp loas into raial contact pressures when the outer collars are pulle together by tightening of the integrate highstrength locking screws. These raial contact pressures in turn accomplish the following: 1. Contract the inner ring an hub to brige the clearance between shaft an hub bore. 2. Generate a efine shaft/hub contact pressure for a high capacity mechanical interference fit. This frictional bon transmits torque, bening an/or thrust loas irectly from the hub to the shaft; the Shrink isc itself oes not carry any torque or thrust loa. M t = rate torque capacity of (1) B-OC Shrink isc with all screws tightene to specifie torque M A as liste in specifications, base on a coefficient of friction µ = 0. an specifie tolerances an clearances. Torque capacities for Half Shrink iscs = M t / 2. Torque capacities for connections using shaft iameters between the minimum an maximum sizes liste can be approximate through interpolation. Transmissible torque ecreases if tolerances an/or clearances are larger than specifie; or if hollow shafts with bores exceeing 5% of shaft iameter are use. THRUST F ax = transmissable thrust, etermine by using the following equation: x M F ax = t, where = shaft iameter (in) TORQUE AN THRUST COMBINE REEASEABIITY Simultaneous transmission of torque an thrust requires calculating a resultant torque: M tres = T 2 + (F x / 2) 2, where: T = peak rive torque (ft-lbs) F = peak thrust loa = shaft iameter (ft) Select a unit where M t M tres. BENING MOMENTS MATERIA UBRICANTS Shrink iscs will generally transmit a continuous bening moment equal to % of rate torque capacity M t. Since the tapers of a B-OC Shrink isc are selfreleasing an stresses from raial contractions of the hub are well within elastic limits, relaxing of the locking screws results in hub expansion back to its original imensions, thereby restoring fit clearance for simple isassembly. Shrink isc inner rings are manufacture from high-carbon steel. Outer rings are mae from forge an heat treate alloy steel. Shrink iscs are supplie with Molybenum isulphie base lubricant applie to the tapers an to the locking screw threas an hea contact areas. SHAFT AN HUB MATERIA iste specifications assume shaft an hub material with a yiel point of at least 5,000 psi. Cast iron hubs are well suite for compressive stresses exerte by B-OC Shrink iscs. However, a lower torsional hub strength generally requires the selection of a Shrink isc at least one size larger than liste if full torque (i.e., that applicable to a steel hub) is to be transmitte. 2

27 ENGTH OF FIT The most recent research on length of fit for a Shrink isc connection* inicates that the hub bore-to-shaft interface shoul be relieve using a non-tolerance clearance except for that portion irectly uner the Shrink isc inner ring, for a fit length equal to for a stanar Shrink isc (see illustration at right). This approach eliminates fretting corrosion between shaft an hub which can make the separation of components ifficult. *(see Casper, Thomas: Reibkorrosionsverhalten von Spanelementverbinungen - Aachen: Mainz, 1) Recommen ength of Fit Equals OCATING AGAINST HUB FACE In applications subjecte to reversing bening moments, we recommen the configuration at right which requires a hub unercut where R e for smooth transition. e R e REGARING SINGE TAPER SHRINK ISCS We generally o not avocate this esign ue to the following limitations: Reuce effective contact length results in significantly higher ynamic fit pressures in applications with bening moments Shallow taper angle means units are not selfreleasing; removal can be ifficult We offer Single Taper Shrink iscs only upon request. 2

31 B-OC RIGI SHRINK ISC COUPINGS B-OC Shrink iscs are perfect for creating custom rigi shaft couplings that transmit high torque an/or bening loas. ue to their high loa capacities, B-OC Shrink isc couplings are frequently use to shaft-mount hyraulic rives an spee reucers. This esign solution: Can easily accommoate ifferent size shafts. Results in a zero backlash interference fit that will never wear out or poun out, even when subjecte to repeate shock or reversing loas. Eliminates the nee for support structures or founations, since the rive/reucer is mounte irectly to the shaft. Eliminates the nee for costly flexible couplings, since shaft misalignment issues isappear. Facilitates quick an easy coupling mounting an isassembly, even in fiel installations. F Series Flange-type Shrink isc Coupling Permits infinite raial an axial ajustment. B-OC can supply a complete coupling or the Shrink iscs only. We re also happy to provie coupling esign an Shrink isc selection assistance. Note that flangetype couplings can also be esigne to be mounte with ocking Assemblies instea of Shrink iscs. In applications using ifferent size shafts where space is limite, it may be possible to employ a owel type coupling, as illustrate below: Sleeve-type Shrink isc Coupling Please contact us for more information on B-OC Rigi Couplings. owel-type Shrink isc Coupling 1
