Abstract
A torque-transmitting connector is disclosed which fits between a spindle and the walls of a bore in a rotating member. The connector includes a sleeve encircling the spindle and two flanges located at its opposite ends. Each flange is initially frustoconical, and is forced into substantially a disc shape to grip the spindle and the wall of the bore. The flange at the bottom of the bore is flattened first by a small diameter punch acting against the other end of the sleeve; and the other flange is then flattened by an annular punch encircling the small diameter punch.
