Abstract
A cylindrical pin couples a driven member, such as a rotor, to a driving shaft by means of axially and angularly aligned cylindrical grooves in the shaft and driven member defining a cylindrical cavity for receiving the pin. The pin fits in the defined cavity and radially bridges the space between the shaft and the driven member to link the two together. The shaft and pin are formed of a metal having a lower thermal coefficient of expansion characteristic than the metal forming the driven member. Torque, applied by the shaft, is applied to the rotor distributed over a portion of the cylindrical side walls of the pin.
