Keyless frictional shaft/hub locking devices - Houston Bearing and ...

THE B-LOC SOLUTIONB-LOC Keyless Frictional Shaft/Hub LockingDevices provide the ultimate solution byincorporating all the advantages of interferencefits, while eliminating mounting and removalproblems.B-LOC Locking Assemblies and Shrink Discs relyon the proven wedge principle to create akeyless, mechanical interference fit by convertinglocking screw tension into radial contact pressureson shaft and hub. This connection, while in manyways similar to conventional shrink or press fits,has several distinct advantages:1. In the relaxed position, B-LOC keylessconnectors provide a generous clearance foreasy mounting and dismounting.2. B-LOC keyless connectors generate highercontact pressures than those obtained by ashrink or press fit, thereby allowing for shorterhub lengths and eliminating the problem offretting corrosion associated with widerconnections.3. B-LOC keyless connectors facilitate simpleaxial and angular timing of hub.B-LOC CORPORATION:COMMITTED TO QUALITYPRODUCTS AND SUPERIORCUSTOMER SERVICESince 1982, B-LOC has been committed toproviding the highest quality keyless lockingdevices to customers worldwide.

B-LOC INTERNAL DEVICES:LOCKING ASSEMBLIESDESIGN FEATURESTORQUEB-LOC Locking Assemblies are well suited to transmittorque, bending, thrust, and radial loads. Proper selectionresults in a zero backlash connection free of wear evenunder severe reversing loads.Use the following criteria to aid in selectingthe right unit for your application:T = peak drive torque = nominal torque multiplied by avariable safety factor to account for stall or start-upconditions, mass accelerations, impact loads, etc.Nominal drive torque can be calculated as follows:M tnom = 5252 x HP / rpmConsult with us in cases where “T” is uncertain.M t = rated torque capacity of (1) B-LOC LockingAssembly with all screws tightened to specified torqueM A as listed in specifications. Tabular values arecalculated without using a safety factor and should beconsidered as the point where a connection could slip if ahigher torque is applied. Therefore, you should alwaysselect a unit where M t ≥ T.Torque capacity and contact pressures are a linearfunction of locking screw tightening torque and may bevaried if this is advantageous for certain applications bychanging M A within the following limits:Series B400:Series B103/B106/B109:Series B800:Series B112/B113:Series B115:up to 20% higheror up to 20% lowerup to 20% lowerup to 20% lowerup to 40% lowerup to 30% lowerIn installations where two or more B-LOC LockingAssemblies are arranged in series with access to lockingscrews from one side only, total torque capacity is not alinear function of the number of units applied. In thesesituations, the factor f mu should be used to compute totaltorque capacity, as follows:M t total = n x M t x f muTHRUSTF ax = transmissable thrust, determined by using thefollowing equation:24 x MF ax = 24 t, where d = shaft diameter (in)dTORQUE AND THRUST COMBINEDSimultaneous transmission of torque andthrust requires calculating a resultant torque:M tres = T 2 + (F x D / 2) 2 , where:T = peak drive torque (ft-lbs)F = peak thrust load (lbs)D = shaft diameter (ft)Select a unit where M t ≥ M tres .BENDING MOMENTSBending moments are a crucial sizing factor inapplications where a radial load from chain pull, theweight of components, etc., acts significantly outside thelocking assembly centerline. Typical applications includerolls or conveyor pulleys where shaft deflection due toradial loads results in a bending moment between shaftand end disc. Generally, bending moments change froma positive to a negative value during each rotation andare designated as rotating or reversing bending moments.B-LOC Locking Assemblies are well suited to transmitrotating/reversing bending moments. As a result ofnumerous successful heavy-duty applications in conveyorpulleys and pertinent investigations by independentinstitutions, the following bending moment capacitiesapply:SeriesBending Moment CapacityB400= 0.22 x M tB103, B106, B109, B800 = 0.28 x M tB115= 0.32 x M tB112 and B113= 0.35 x M tConsult with us for applications where the bending momentcapacity exceeds these recommended limits.10Factors “f mu ”for determining total torque capacity inmultiple unit Locking Assembly installationsLocking Assembly n = number of units in seriesType2 3 4B400 & B103 .80 .75 .70B115 .80 .75 N/AB112 .85 N/A N/AB113 .90 N/A N/ATORQUE AND BENDING COMBINEDSimultaneous transmission of torque andbending requires calculating a resultant torque:M tb = T 2 + (2M b ) 2 , where:T = peak drive torque (ft-lbs)M b = bending moment (ft-lbs)Select a unit where M t ≥ M tb and M b is within the limitsshown above.

CONCENTRICITYB-LOC Locking Assemblies provide good to perfectconcentricity in a variety of applications. The level ofconcentricity depends on taper angle and length, hubpre-centering, and mode of screw tightening. The followingdescription of features should be helpful in selecting themost suitable device to meet specific concentricityrequirements.TEMPERATURE INFLUENCESimilar to conventional shrink or press fits, B-LOCLocking Assembly connections are not affected bytemperature changes as long as they apply equally tohub and shaft. Since temperatures above 400 deg. Flower the strength of most commonly used materials,special considerations are necessary for connectionsworking in temperatures higher than 400 deg. F.SERIES B400: The relatively narrow width of thesedouble collar devices usually necessitates the need for apre-centering hub section. Type of fit as well as the lengthof this pre-centering section greatly influences concentricity.The use of pilot bushings permits the reduction of hublength or even the elimination of pre-centering hubsections in the case of a roll configuration. These unitsprovide concentricity sufficient for low to medium speedcomponents.SERIES B103, B106, B109, B800: TheseLocking Assemblies do not require a pre-centering hubsection. The I.D., O.D. and taper of these units aremachined in a single set-up ensuring perfect concentricityfor the locking assembly itself. Total system concentricity willdepend on installed components, but is typically excellent,even for high speed applications.SERIES B115, B112, B113: The good precenteringcharacteristics of these devices, combined withtheir wide double taper design, provides excellentconcentricity for any type of application.RADIAL LOADSRadial loads are generated by forces appliedperpendicular to the centerline of the shaft, and arefrequently associated with pin or axle connections.B-LOC Locking Assemblies are well suited to provide atight, backlash-free fit for such connections (see illustrationbelow).F rad = radial load capacity = d x L x P, where:d = shaft diameter (in)L = contact length (in), see spec. tablesP = shaft contact pressure (psi)Typical pressure distribution in backlash-free pin connectionsd=pin diameterHOLLOW SHAFTSSECURING OF LOCKING SCREWSRELEASABILITYMATERIALHollow shafts with bores exceeding 35% of outsidediameter usually require a reduction of contactpressures in order to avoid permanent shaftcontraction. Consult with us for the amount of reductionrequired or for corrective measures available for atrouble-free hollow shaft application.Specified locking screw tightening torque M A assuressufficient pre-load so that screws are self-locking, evenin cases where B-LOC Locking Assemblies aresubjected to extreme vibratory conditions.B-LOC Locking Assemblies and Shrink Discs aredesigned for fast and easy removal. Our B400 LockingAssemblies, as well as all B-LOC Shrink Discs, featureself-releasing tapers. All other types use self-lockingtapers for a more efficient clamp load conversion andhigher bending moment capacities. For these units, asufficient number of integrated push-off holes assurepositive dismounting even after many years of service.B-LOC Locking Assemblies are manufactured from heattreated high-carbon and alloy steels. Please contact usfor applications requiring stainless steel. Corrosionresistance can be improved through the application ofindustry standard plating materials and/or the use ofprotective cover plates.Loadp min. = p - p L≥ 0Explanations:p = contact pressure providedby Locking Ass’y.p L = contact pressure onprojected contact areaload=d x contact lengthY.

The maximum wall thickness ofan adaptor sleeve should be approximately 10%of the shaft diameter. The minimum thickness willdepend upon the machining process.It is important to note that in order to maximizethe torque capacity of a sleeved Locking Assemblyconnection, the shaft/sleeve bore interface shouldbe free of any lubricant, resulting in a coefficient offriction µ = 0.15 and making the sleeve OD/LockingAssembly bore the point of lowest torque capacity(provided the sleeve OD is less than 1.25 times the shaftdiameter). This facilitates full use of the larger Locking Assembly’shigher torque capacity.Notes:1. Sleeve ID = d s -0/+.001“ where d s = shaft dia.2. Sleeve OD = d +0/-T for Locking Assembly tobe used.3.

HUB SIZINGB-LOC Locking Assemblies transmit torque and otherloads by means of mechanical interference generated bypressure exerted on both the shaft and hub, meaningthat consideration must be given to the amount of hubmaterial required to prevent permanent expansion (i.e.,yielding). The following information is provided to assistyou in determining the required hub OD for any LockingAssembly application.Using the stress equations presented at right, therequired hub OD "D N " is determined as follows:THICK WALLED CYLINDERSUBJECTED TO INTERNAL PRESSUREσ tσ rοοPi⊕⊕id d xDTHICK WALLED CYLINDERSUBJECTED TO EXTERNAL PRESSUREPσ tσ ri⊕οο⊕iwhere D = hub bore (inches) from specification tables,and . . .p = contact pressure (psi) applied to hub bore fromHspecification tablesY.P. =24D N = DY.P. + (p x C)HY.P. - (p x C)yield point (psi) of hub material (see below)C = Stress Reduction Factor, considering therelationship of actual hub width "B" (asdetermined by customer) to Locking Assemblycontact length "L" (per specification tables),determined as follows (assumes lockingassembly collar in contact with hub bore iscentered in hub):For Series B103, B106, B109, B400 and B800C = 1.0 for B = LC = 0.8 for B = 1.5 x LC = 0.6 for B = 2.0 x LFor Series B112, B113 and B115C = 1.0 for B = LC = 0.8 for B = 1.25 x LC = 0.6 for B = 1.50 x LThis equation can also be expressed as D N =DK, whereY.P. + (p x C)HK represents the expression .Y.P. - (p x C)HThe table at right provides these “K” factors for variouscombinations of Y.P., p , and C.

B-LOC EXTERNAL DEVICES:SHRINK DISCS & WK SERIES RIGID SHAFT COUPLINGSDESIGN FEATURESTORQUEExternal locking devices for keyless frictional shaft/hubconnections on shafts from 5/8” to 40” diameter,B-LOC Shrink Discs . . .• Provide a high capacity interference fit with all thepositive features of conventional interference fits, butwithout their assembly and dismounting problems.• Offer extremely concentric and well-balancedconnections, ideal for high-speed applications.• Permit simple axial and angular timing.• Are available in standard, light, and heavy-dutyseries to suit any application.WORKING PRINCIPLEThe double tapered inner ring of a B-LOC Shrink Discprovides a high-ratio conversion of screw clamp loadsinto radial contact pressures when the outer collars arepulled together by tightening of the integrated highstrengthlocking screws. These radial contact pressuresin turn accomplish the following:1. Contract the inner ring and hub to bridgethe clearance between shaft and hub bore.2. Generate a defined shaft/hub contact pressure fora high capacity mechanical interference fit.This frictional bond transmits torque, bending and/orthrust loads directly from the hub to the shaft; theShrink Disc itself does not carry any torque or thrustload.M t = rated torque capacity of (1) B-LOC Shrink Discwith all screws tightened to specified torque M A aslisted in specifications, based on a coefficient of frictionµ = 0.15 and specified tolerances and clearances.Torque capacities for Half Shrink Discs = M t / 2.• Torque capacities for connections using shaftdiameters between the minimum and maximum sizeslisted can be approximated through interpolation.• Transmissible torque decreases if tolerances and/orclearances are larger than specified; or if hollow shaftswith bores exceeding 35% of shaft diameter are used.THRUSTF ax = transmissable thrust, determined by using thefollowing equation:24 x MF ax = 24 t, where d = shaft diameter (in)dTORQUE AND THRUST COMBINEDRELEASEABILITYSimultaneous transmission of torque andthrust requires calculating a resultant torque:M tres = T 2 + (F x D / 2) 2 , where:T = peak drive torque (ft-lbs)F = peak thrust load (lbs)D = shaft diameter (ft)Select a unit where M t ≥ M tres .BENDING MOMENTSMATERIALLUBRICANTSShrink Discs will generally transmit a continuousbending moment equal to 25% of rated torquecapacity M t.Since the tapers of a B-LOC Shrink Disc are selfreleasingand stresses from radial contractions of thehub are well within elastic limits, relaxing of the lockingscrews results in hub expansion back to its originaldimensions, thereby restoring fit clearance for simpledisassembly.Shrink Disc inner rings are manufactured fromhigh-carbon steel. Outer rings are made from forgedand heat treated alloy steel.Shrink Discs are supplied with Molybdenum Disulphidebased lubricant applied to the tapers and to the lockingscrew threads and head contact areas.SHAFT AND HUB MATERIALListed specifications assume shaft and hub materialwith a yield point of at least 45,000 psi. Cast ironhubs are well suited for compressive stresses exerted byB-LOC Shrink Discs. However, a lower torsional hubstrength generally requires the selection of a ShrinkDisc at least one size larger than listed if full torque(i.e., that applicable to a steel hub) is to be transmitted.26

LENGTH OF FITThe most recent research on length of fit for a Shrink Discconnection* indicates that the hub bore-to-shaft interfaceshould be relieved using a non-toleranced clearanceexcept for that portion directly under the Shrink Disc innerring, for a fit length equal to “L” for a standard Shrink Disc(see illustration at right). This approach eliminates frettingcorrosion between shaft and hub which can make theseparation of components difficult.*(see Casper, Thomas:Reibkorrosionsverhalten von Spanelementverbindungen -Aachen: Mainz, 1999)RecommendLength of FitEquals “L”LOCATING AGAINST HUB FACEIn applications subjected to reversing bendingmoments, we recommend the configuration at rightwhich requires a hub undercut where R ≥ e for smoothtransition.eR ≥ eREGARDING SINGLE TAPER SHRINK DISCSWe generally do not advocate this design due to thefollowing limitations:• Reduced effective contact length results insignificantly higher dynamic fit pressures inapplications with bending moments• Shallow taper angle means units are not selfreleasing;removal can be difficultWe offer Single Taper Shrink Discs only upon request.27

B-LOC RIGID SHRINK DISC COUPLINGSB-LOC Shrink Discs are perfect for creating custom rigidshaft couplings that transmit high torque and/or bendingloads. Due to their high load capacities, B-LOC ShrinkDisc couplings are frequently used to shaft-mounthydraulic drives and speed reducers. This designsolution:• Can easily accommodate different sized shafts.• Results in a zero backlash interference fit that willnever wear out or pound out, even when subjectedto repeated shock or reversing loads.• Eliminates the need for support structures orfoundations, since the drive/reducer is mounteddirectly to the shaft.• Eliminates the need for costly flexible couplings,since shaft misalignment issues disappear.• Facilitates quick and easy coupling mounting anddisassembly, even in field installations.F SeriesFlange-type Shrink Disc Coupling• Permits infinite radial and axial adjustment.B-LOC can supply a complete coupling or the ShrinkDiscs only. We’re also happy to provide coupling designand Shrink Disc selection assistance. Note that flangetypecouplings can also be designed to be mounted withLocking Assemblies instead of Shrink Discs.In applications using different sized shafts where space islimited, it may be possible to employ a “dowel” typecoupling, as illustrated below:Sleeve-type Shrink Disc CouplingPlease contact us for more informationon B-LOC Rigid Couplings.Dowel-type Shrink Disc Coupling31
