Frictional shaft-hub-connections Why frictional shaft-hub-connections? Frictionalshaft-hub-connectionsarestandard machine elements used to connect shafts and hubs. They are capable of transmitting torque,axialforces,radialforcesandbending moments. ShrinkDiscsandConeClampingElements Among the frictional shaft-hub-connections ShrinkDiscsandConeClampingElementstake animportantposition.Bytighteningclamping screws conical surfaces are pulled together generatingradialforces;theseforcesprovide therequiredfrictionalconnectionbetweenthe partsinvolvedinthetransmissionoftorquesor forces....

Design and Function of Shrink Discs Two-part Shrink Discs Design and Function Two-part shrink discs consist of an outer stepped conical ring, and an inner stepped conicalbush,aswellasanumberofclamping screws(seeFigure10-1). The stepped conical ring is pulled onto the steppedconicalbushbytighteningtheclamping screws. A radial clamping force is generatedbytheconicalsurfaces,whichisindependentofthefrictioncoefficientsatthescrews andconicalsurfaces.Theradialclampingforce presses the hollow shaft onto the shaft and createsafrictionalconnectionatthecontact surfaces between the shaft and the...

Design and Function of Shrink Discs Three-part Shrink Discs Pressureflange Innerring Three-part shrink discs consist of a threaded flange,apressureflange,aslottedinnerringand anumberofclampingscrews(seefigure11-1). Hollowshaft Clampingscrews Thethreadedflangeandthepressureflange are pulled together over the inner ring by tightening the clamping screws. A radial clamping force is generated by the conical surfaces which is dependent on the friction coefficientsatthescrewsandconicalsurfaces.
