摘要

A coupling member is shrink fitted onto the end of a dynamoelectric machine shaft and keyed thereto with a plurality of hollow keys of circular cross section which distort if excessive torque is applied to the coupling, reducing the risk of coupling failure. This coupling exhibits the properties of high strength and low weight which eliminates lateral shaft resonance at operating speeds.
