A railway locomotive truck provides improved mountings and/or configurations for traction motor axle support bearings to improve their wear life. These include tilting, or sloping, of the support bearing bores to more closely match the orientations of the bearing journal surfaces on the axles which slope as a result of bending of the axles under the weight of the locomotive. An added feature is forming the bearing bores with a slight conicity to accommodate slight tilting of the traction motor under heavy loads due to taking up of the clearances in the m...
A traction motor for a railway power vehicle of the type having a body, a rail engagable wheel and axle assembly including a pair of laterally spaced driving wheels fixed to an axle with motor support journals on the axle inwardly adjacent the wheels, said body being supported on at least one wheel and axle assembly by suspension means engaging the axle at support points outboard of the wheels, whereby the weight of the body causes slight concave downward bending of the axle between the wheels with resulting outwardly downward sloping of the support jour...
