THE KEY TO BETTER MACHINE DESIGNIS NO KEY AT ALL.

INTRODUCTION:

In a typical keyed shaft/hub connection, theclearance between key and keyway required forfitting is a serious disadvantage when shock orreversing loads are to be transmitted. Anycomponent held by a key is slipping on the shaftat start-up or load reversal by an amount equal tothe amount of fit clearance. This results in impactloads when contact with the key stops theslippage. These impact loads, which are rarelyaccounted for in the design process, generate acontinuous �pounding� between key and keyway.This pounding, combined with fretting corrosioncaused by micromovements at the fit interface,frequently leads to shaft failures like the onesillustrated above. [Shaft failure illustrations arereproduced with permission of Sachs, Salvetera &Associates, Solvay, NY.]

The solution to these problems is elimination ofthe key by using a frictional bond betweencomponents and shafts. This type of connection,commonly known as an interference (shrink orpress) fit, results in zero clearance � hence, nobacklash � and utilizes the full contact area foruniform transmittal of torques and/or bendingmoments. Such a connection will never �poundout�� even for an infinite number of load cycles �as long as the frictional holding capacity of theconnection is equal to or higher than the loadsapplied. In addition, the elimination of keywayseliminates keyed shaft notch factors, permittingsmaller shaft and bearing sizes and reducing theoverall cost and complexity of a design. Despitethese advantages, mounting and removalproblems associated with shrink or press fits havefrequently disqualified this type of connection formany applications.

THE PROBLEM: TRADITIONAL INTERFERENCE FITS:

B-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-LLOC keylessconnectors provide a generous clearance foreasy mounting and dismounting.

2. B-LLOC 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-LLOC keyless connectors facilitate simpleaxial and angular timing of hub.

DESIGN FEATURES THRUST

BENDING MOMENTS

B-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 selecting the 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:

Mtnom = 5252 x HP / rpm

Consult with us in cases where �T� is uncertain.

Mt = rated torque capacity of (1) B-LOC LockingAssembly with all screws tightened to specified torqueMA 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 Mt ≥ 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 MA within the following limits:

Series B400: up to 20% higher or up to 20% lower

Series B103/B106/B109: up to 20% lowerSeries B800: up to 20% lowerSeries B112/B113: up to 40% lowerSeries B115: up to 30% lower

In 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 fmu should be used to compute totaltorque capacity, as follows:

Mt total = n x Mt x fmu

Bending 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:

Series Bending Moment CapacityB400 = 0.22 x MtB103, B106, B109, B800 = 0.28 x MtB115 = 0.32 x MtB112 and B113 = 0.35 x Mt

Consult with us for applications where the bending momentcapacity exceeds these recommended limits.

TORQUE

TORQUE AND THRUST COMBINED

TORQUE AND BENDING COMBINED

Simultaneous transmission of torque and bending requires calculating a resultant torque:

Mtb = T2 + (2Mb)2, where:T = peak drive torque (ft-lbs)Mb = bending moment (ft-lbs)

Select a unit where Mt ≥ Mtb and Mb is within the limitsshown above.

RADIAL LOADS

Radial loads are generated by forces applied perpendicular 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).

Frad = radial load capacity = d x L x P, where:d = shaft diameter (in)L = contact length (in), see spec. tablesP = shaft contact pressure (psi)

TEMPERATURE INFLUENCE

B-LOC Locking Assemblies provide good to perfectconcentricity in a variety of applications. The level ofconcentricity depends on taper angle and length, hub pre-centering, and mode of screw tightening. The followingdescription of features should be helpful in selecting themost suitable device to meet specific concentricityrequirements.

SERIES B400: The relatively narrow width of these double 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 pre-centering characteristics of these devices, combined withtheir wide double taper design, provides excellentconcentricity for any type of application.

Similar 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.

Hollow 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 MA 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.

B-LOC Locking Assemblies are supplied lightly coatedwith ordinary machine oil.

LOCKING ASSEMBLY CONNECTIONS WITHSHAFT-ADAPTOR SLEEVES:In applications where an existing shaft diameter does not fitthe bore of a standard B-LOC Locking Assembly, werecommend using an adaptor sleeve sized to facilitatethe use of a standard sized Locking Assembly andthe existing shaft. 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 = ds -0/+.001� where ds = shaft dia.

2. Sleeve OD = d +0/-T for Locking Assembly tobe used.

3. Install DRY at shaft/sleeve bore interface forcoefficient of friction µ =0.15.

4. Torque capacity at sleeve OD = Mt forLocking Assembly to be used.

5. Torque capacity on shaft = Mt x x 1.25.

6. Sleeve to be manufactured with one lengthwiseslit (after machining) and from material equal to or

better than shaft material.

7. Sleeve can be installed over existing keyway; positionslit approximately opposite keyway.

HUB SIZING

B-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 "DN" is determined as follows:

where D = hub bore (inches) from specification tables,and . . .

p = contact pressure (psi) applied to hub bore fromspecification tables

Y.P. = yield point (psi) of hub material (see below)

C = Stress Reduction Factor, considering the relationship of actual hub width "B" (as determined by customer) to Locking Assembly contact length "L" (per specification tables), determined as follows (assumes locking assembly collar in contact with hub bore is centered 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 L

For 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 L

This equation can also be expressed as DN=DK, where

K represents the expression .

The table at right provides these �K� factors for variouscombinations of Y.P., p , and C. To use the table,determine the Yield Point (in psi) of your hub material,find the p value for the Locking Assembly you�veselected from the appropriate specification table (roundup to the nearest 1,000 psi), and determine the value ofC based on your component�s length-thru-bore (LTB).Then, find the K factor from the table and multiply by theLocking Assembly OD to calculate the minimum requiredhub OD for your application.

Fax = transmissable thrust, determined by using thefollowing equation:

Fax = 24 x Mt , where d = shaft diameter (in)

Simultaneous transmission of torque and thrust requires calculating a resultant torque:Mtres = T2 + (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 Mt ≥ Mtres.

Since the tapers of a B-LOC Shrink Disc are self-releasing and 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 Discs will generally transmit a continuousbending moment equal to 25% of rated torquecapacity Mt.

Shrink Disc inner rings are manufactured from high-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.

B-LOC EXTERNAL DEVICES:SHRINK DISCS & WK SERIES RIGID SHAFT COUPLINGS

External 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.

The 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 high-strength locking screws. These radial contact pressuresin turn accomplish the following:

1. Contract the inner ring and hub to bridge the 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.

DESIGN FEATURES

WORKING PRINCIPLE

Listed 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.

• 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.

The 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)

LENGTH OF FIT

RecommendLength of FitEquals �L�

In applications subjected to reversing bendingmoments, we recommend the configuration at rightwhich requires a hub undercut where R ≥ e for smoothtransition.

LOCATING AGAINST HUB FACE

We 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 self-releasing; removal can be difficult

We offer Single Taper Shrink Discs only upon request.

B-LOC RIGID SHRINK DISC COUPLINGS

B-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 or foundations, since the drive/reducer is mounted directly to the shaft.

• Eliminates the need for costly flexible couplings, since shaft misalignment issues disappear.

• Facilitates quick and easy coupling mounting and disassembly, even in field installations.

• 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 flange-type couplings 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:
