ABSTRACT:
Locomotive traction motors have conventionally been used in North America with sleeve-type friction bearing suspension systems. Roller bearing suspension systems have been gaining acceptance in North America. There is no known method of converting the sleeve-type systems to roller bearing systems. This problem is overcome by a method in which the bearing caps covering the sleeve bearings, the sleeve bearings and the shaft are removed; recesses are formed in the bearing caps and in the traction motor housing proximate the ends of the traction motor for receiving roller bearing housings at each end of the traction motor housing; installing the roller bearing housings on an axle and in said recesses in the bearing caps; mounting a generally U-shaped cover between the bearing caps, the U-shaped cover and bearing caps surrounding the central portion of the axle; and connecting the bearing caps to the traction housing.
