Dynamoelectric machine with improved lubrication wicking system

A dynamoelectric machine with an improved lubrication system and comprising:

• a stator;
• a rotor within said stator and located on a shaft;
• at least one bearing for permitting rotation of said shaft and rotor, said bearing comprising a cylindrical sleeve type bearing surface mounted in a housing secured to said stator;
• a wicking arrangement for continuously supplying liquid lubricant to said bearing surface, said wicking arrangement comprising a feeder wick extending from within said housing through a window in said bearing surface to contact said shaft, a mass of particulate wicking material within said housing away from said window and in close contact with surfaces of said feeder wick, said mass of wicking material being less lubricant retentive than said feeder wick, a collector wick that is ring shaped and secured within said housing and has a surface abutting against an end of said mass of particulate wicking material, said collector wick being proximate and exposed to a lubricant flinger mounted on said shaft, said collector wick comprising an open celled foamed plastic material whose density and lubricant retentivity is less than said feeder wick and said mass of particulate wicking material.
