Abstract

Abstract A dynamoelectric machine is disclosed comprising a stator, a shaft having a rotor fixed thereto, and a bearing supporting the rotor shaft for rotation with respect to the stator. A lubricant retaining reservoir is mounted in spaced relation laterally about the bearing. A lubricant absorbent mass is mounted within the lubricant retaining reservoir flush with the bearing from which mass lubricant may be supplied to the bearing. A grooved surface is disposed within the reservoir to receive excess lubricant from lubricant saturated portions of the mass in contact with the grooved surface and from which excess lubricant may be resupplied to portions of the mass in contact with the grooved surface when such portions are unsaturated with lubricant.
