ABSTRACT:
A wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing support, a bore for the reception of the rotor shaft, and a longitudinal slot therein with a portion of the slot opening into the bore and extending longitudinally through the bearing. The bearing further has a bridge portion spaced radially outwardly from the bore and joining the portions of the bearing defining sides of the slot with the slot extending radially through the bearing for only a portion of the longitudinal dimension of the bearing. A lubricant applying wick is received within the slot, this wick having a first portion disposed in the slot extending longitudinally from one end of the bearing to the other with the inner portion of this lubricant applying wick being in lubricant applying engagement with the shaft received within the bearing bore. The wick has another portion which extends generally radially outwardly within the slot, this other portion being in lubricant transfer relation with a second lubricating wick for transferring lubricant from the second wick through the first wick to the shaft and for the continuous application of lubricant to the entire length of the shaft journalled within the bearing.
