BEARING LOCK FOR A DYNAMOELECTRIC MACHINE

BEARING LOCK FOR A DYNAMOELECTRIC MACHINE Of The Invention A bearing locking construction for dynamoelectric machines having a bearing locking assembly which can be located in place after an electric motor or other dynamoelectric machine is completely assembled. The construction includes a bearing housing which has at least a pair of abutments located on opposite sides of the motor shaft which house a fastening means for locating the bearing lock and securing the bearing in its seat and consists of fasteners which are assembled through the abutments from the outboard side of the motor and has a large T-shaped head rotated by rotation of the fastener to overlap the bearing on one side and an axially spaced seat on the opposite side. Stops or tabs located on both sides of the head prevent the fastener from rotating once it is in place and the fastener is secured in place with a preload thereon by several different constructions which draw the fastener outwardly to force the inner end of the head against the outer bearing race and the outer end of the head against the spaced seat. The fastener may be internally threaded and receive a screw with a head assembled over a washer to secure the screw head and washer to the outboard side of the abutment when threaded into the fastener. The fastener may include a threaded shaft to receive a nut which abuts against the outboard side of the abutment.
