DETACHABLE HUB FOR MOUNTING REVOLVING MEMBER ON DRIVE SHAFT AND REVOLVING MEMBER EQUIPPED WITH SUCH HUB Russian patent published in 2001 - IPC

FIELD: revolving members, such as gear wheels, pulleys and detachable hubs for mounting such revolving members. SUBSTANCE: detachable hub includes at least one member with radial slot, coupling screws for clamping above-mentioned member of hub on drive shaft and split ring located between drive shaft and hub member to ensure clamping of hub member on drive shaft. Hub member includes split part with taper outer surface which extends as rectilinear split part of smaller diameter. Besides that, nut and split ring with taper outer surfaces are provided; ring is clamped on rectilinear part of hub member by means of this nut in position symmetrical relative to above- mentioned taper surface of split part of hub with taper outer surface relative to vertical plane, giving access to revolving member on either side. Revolving member mounted of drive shaft by means of detachable hub has inner wall with two taper parts which are symmetrical relative to center vertical plane to ensure possibility of mounting the detachable hub on either side of revolving member. EFFECT: avoidance of mounting revolving member on drive shaft by means of key joint; optimal clamping for transmission of required torque. 7 cl, 4 dwg
