Title: Dynamoelectric machine with improved lubrication wicking system

Abstract: Sleeve type rotor bearings with a wicking arrangement for continuously supplying oil to the bearing surface including a feeder wick extending from within the bearing housing through a window in the bearing surface to contact the rotating shaft, a mass of particulate wicking material in close contact with surfaces of the feeder wick and giving up lubricant to the feeder wick, and a collector wick that is ring shaped and has a surface abutting against an end of the mass of particulate wicking material and is exposed to an oil flinger mounted on the shaft; the collector wick comprises an open cell foamed plastic material whose density and lubricant retentivity is less than either the feeder wick or the mass of particulate wicking material. The arrangement provides good oil collection without encountering problems of oil runout.
