Abstract: An end shield for an electric motor or the like includes a generally disk shaped planar portion having a cylindrical bearing socket therein for mounting a cylindrical bearing. The socket has a cylindrical side wall and an end wall, and is formed from ears and tabs from the material of the disk such that the ears are bent out of the plane of the disk to extend at right angles to the planar portion. The ears define the cylindrical side wall of the socket. The tabs extend generally radially inwardly and define the end wall of the socket. A cylindrical bearing within the socket is retained radially and in axial alignment by the cylindrical side wall of the socket, and is restrained in an axial direction by the end wall of the socket. A spring may be mounted within the socket to resiliently preload the bearings of the motor in the axial direction.

Abstract: A fiber reinforced plastic leaf spring including a curved central section and a pair of end sections, each having a bushing to receive a connecting member. The spring is formed from a plurality of longitudinally extending substantially continuous strands of fibrous material impregnated with a cured thermosetting resin which are wound in a loop configuration around the bushings. The windings consist of a pair of generally parallel runs which extend between the bushings and are disposed in contiguous relation and the resin is cured to formed an integral structure. Each bushing includes a tubular section and at least one circumferentially extending rib that extends outwardly from the tubular section and is encapsulated in the fibrous windings. The ribs act to prevent delamination of the two runs along the neutral axis of the spring when the spring is subjected to load in service.
