ABSTRACT:
A conical stressing device for connecting a hub to a shaft, the device including a double conical stressing assembly adapted to be mounted on the outer periphery of the hub, so that the hub may be radially compressed to attach it rigidly to the shaft by frictional forces, the double conical stressing assembly including: (1) a double conical ring which has two coaxial peripheral surfaces axially spaced apart and tapering in opposite directions, whereby the greatest wall thickness of the double conical ring is in the central region of its axial length, (2) two conical rings, each of which possesses a conical peripheral surface that acts in conjunction with a respective conical surface of the double conical ring, and (3) axial tensioning bolts which are distributed around the perimeter and are inserted in holes drilled axially in the conical rings, the axial tensioning bolts placing the conical rings under axial tension to force them to slide along the conical surfaces, wherein one of the conical rings tensions the double conical stressing assembly around the hub and the other conical ring tensions the double conical stressing assembly axially on the shaft in front of the hub.
