    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.

    摘要： A tapered roller bearing (31) has pockets to house tapered rollers (34) and includes a plurality of retainer segments (11a) to (11d) arranged so as to be continuously lined with each other in a circumferential direction between an outer ring (32) and an inner ring (33). The retainer segments (11a) to (11d) include at least a first retainer segment having a first circumferential length, and a second retainer segment having a second circumferential length different from the first circumferential length. After the retainer segments (11a) to (11d) have been arranged in the circumferential direction without space therebetween, a circumferential clearance (39) is provided between the retainer segment (11a) arranged first and the retainer segment (11d) arranged last. A circumferential range of the clearance is larger than 0.08% and smaller than 0.10% of a circumference of a circle passing through a center of the retainer segment at room temperature.

    摘要： A plurality of tapered rollers are retained between an outer ring and an inner ring by a retainer so as to be circumferentially spaced apart from each other. The inner ring is formed with a raceway on its outer surface and includes a small-diameter flange and a large-diameter flange 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 (conical surface defined by the axes of the tapered rollers) to increase the thickness of the crossbars as well as the axial thickness of the small-diameter annular portion. The rigidity of the retainer thus increases. 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, thereby further increasing the rigidity of the retainer, and also to increase the contact length between the tapered rollers and the crossbars, thereby stabilizing the rotation of the tapered rollers about the axis of the bearing.

    摘要： A tapered roller bearing includes a retainer formed with a plurality of trapezoidal pockets. Each pocket includes cutouts formed in the crossbars defining each pocket near the narrow end thereof. A tapered roller is received in each pocket with its small-diameter end facing the narrow end of the pocket. Lubricating oil flowing into the bearing space defined radially inwardly of the retainer can quickly flows through the cutouts into the bearing space defined radially outwardly of the retainer at the narrow end of each pocket. Thus, it is possible to reduce the amount of lubricating oil flowing along the raceway of the inner ring to the large-diameter flange, and thus reduce the amount of lubricating oil remaining in the bearing, thereby reducing the torque loss due to rotational resistance of the bearing resulting from lubricating oil remaining in the bearing.
