ABSTRACT:
A unit bearing motor includes a frame member having opposite sides and a bearing post thereon, the bearing post having first and second opposite ends with first and second spaced bearing portions respectively extending axially inwardly from the ends. The bearing post has a first portion extending from one side of the frame member to the first end and a second portion extending from the other side of the frame member to the second end. The shaft of the machine is rotatably supported in the bearing portions and has a portion extending from the first end of the bearing post for supporting the rotor of the machine. A cup member is secured to the other side of the frame member and encloses the second portion of the bearing post to define a lubricant reservoir. The frame member has openings formed therethrough outwardly from the bearing post and communicating with the reservoir. Lubricant absorbent material is located in the reservoir and a first wick is arranged to abstract lubricant from the absorbent material and to feed it to the second bearing portion in one direction of shaft rotation and to return lubricant from the second bearing portion to the absorbent material in the other. A second wick extends over the first bearing post portion and has portions extending through a frame opening and arranged to return lubricant to the absorbent material, and to remove lubricant from the first bearing portion in the one direction of shaft rotation, and to extract lubricant from the absorbent material and feed it to the first bearing portion in the other.
