摘要： Tapered rollers are retained between outer and inner rings by a retainer to be circumferentially spaced apart from each other. The inner ring has a raceway on its outer surface and includes small and large-diameter flanges at the small- and large-diameter ends of the raceway, respectively. The retainer includes two annular portions and crossbars extending between the annular portions. Its radially inner surface is located radially inwardly of the pitch cone of the tapered rollers to increase the thickness of the crossbars and the axial thickness of the small-diameter annular portion. The conical surface defined by the outer surfaces of the crossbars has an inclination angle that is greater than the central angle of the bearing to increase the volume of the crossbars. The rigidity of the retainer is thus increased.

The retainer further includes a disk portion extending radially inwardly from the axially outer end of the small-diameter annular portion, and a third annular portion extending axially outwardly from the radially inner end of the disk portion. The third annular portion has a radially inner guided surface guided by the radially outer guiding surface of the inner ring spacer. A hardened surface layer and a lubricating film are formed on the radially outer guiding surface of the inner ring spacer.

摘要： An angular contact ball bearing includes a plurality of balls disposed between raceways of inner and outer bearing rings. Each ball is in contact with at least one of the raceways at two points having different contact angles from each other and located on an opposite side of a bearing centerline from a point at which each ball is in contact with the other of the raceways. The bearing is a full complement bearing, wherein the balls are arranged in a full complement. With this arrangement, it is possible to minimize the contact stress at the two contact points where the radial load and the axial load in one direction are supported, thereby reducing elastic deformation at the two contact points. This makes it possible to further increase the rigidity of the bearing.
