Abstract:
An electric machine includes an end frame having a shaft bore extending therethrough. The end frame includes a first side and a second side. A shaft extends through the shaft bore. A bearing is supported by the end frame and is coupled to the shaft to support the shaft for rotation about a longitudinal axis. A first seal is fixedly attached to the end frame and includes an internal bore that is sized to cooperate with the shaft to form a seal point therebetween. The first seal is disposed on the first side of the end frame. A second seal is fixedly attached to the second side of the end frame. The second seal includes a movable portion in direct contact with the shaft to define a second seal point. The first seal point is on a first side of the bearing and the second seal point is on a second side of the bearing.
