ABSTRACT:
To couple a hub having a connecting boss to a shaft, with improved centricity and torque transmission, the hub is formed with a ring groove in the end face leaving a protruding boss surrounding the shaft, in which ring groove a pair of concentric rings having matching continuous conical surfaces are inserted, the depth of the ring groove, and the rings themselves being so relatively dimensioned that, in loosely assembled condition, the inner surface of the outer ring is spaced from the axially facing surface of the ring groove by a pretermined distance which is taken up during tightening, the inner face of the ring groove then forming a stop or abutment surface upon such axial tightening of the outer ring over the inner ring to completely fill the ring groove and provide for radial support of the hub in the region of the ring groove as well as for transfer of power from the shaft to the hub by engagement of the boss of the hub with the shaft, and of the rings with each other and with the hub, respectively.
