ABSTRACT:
A two-part electric motor shaft assembly. The assembly includes an elongated shank member which has a cavity hollowed out at one end. A cam pin has one end configured to be received in the shank cavity and secured thereto. The other end of the cam pin forms a cam surface which is eccentric with respect to a longitudinal axis defined by the elongated shank member. By utilizing a two-piece design, the shank member may be formed of a softer and less expensive material than the alloy steel used to form the cam pin since the shank member is subjected to less loading and wear. The two-part motor shaft assembly of the present invention eliminates the stress riser that occurs with application of loading to the transition joint of a single piece design.
