ABSTRACT:
A fractional horsepower electric motor comprises a stator, a shell supporting the stator, end members closing the ends of the shell, a shaft supporting a rotor within the stator, a bearing system on the end members rotatably supporting the shaft comprising a bearing member on the shaft engaging a seat on the end member, a spring yieldingly urging the bearing member against the seat, an oil retention body associated with the bearing member, a spacer on the shaft, and a composite washer interposed between said spacer and said bearing member through which said shaft extends. The composite washer comprises a base layer of plastic filament material, a layer of resilient elastic material bonded to one surface of the base layer, and an oil impregnated layer bonded to the other surface of the base layer and engaging said bearing member, whereby oil from the bearing passes through the base layer in capillary fashion and upon rotation is directed in small droplets toward said oil reservoir.
