Abstract: A corner is formed at a small-diameter-side end portion of a cage. The cage is disposed such that the axial position of a tip of the corner substantially coincides with the axial position of a large end face of an outer ring. Thus, a cylindrical space formed between an inner periphery cylindrical face of the outer ring and an outer periphery cylindrical face of the cage is filled with an oil low pressure region. As a result, the inflow of the oil into a bearing is restricted.
Abstract translation: 在保持架的小直径侧端部形成有角部。 保持架设置成使得角部的尖端的轴向位置与外圈的大端面的轴向位置大致重合。 因此，在外圈的内周圆柱面和保持架的外周圆筒面之间形成的圆筒状的空间填充有油低压区域。 结果，限制了油进入轴承的流入。

Abstract: A rolling bearing includes inner and outer races rotatable relative to each other, a plurality of rolling elements interposed between the inner and outer races, and a retainer arranged between the inner and outer races for retaining the plurality of rolling elements equiangularly. Flange portions are formed on a radially inner side and a radially outer side of an axial end portion of the retainer so as to extend radially. Recessed grooves are formed in a region of the inner race and a region of the outer race corresponding to the respective flange portions so as to form labyrinths together with the flange portions. Inner side surfaces of the flange portions and axial end surfaces of the recessed grooves, which are opposed to the inner side surfaces of the flange portions, are inclined radially so as to generate a flow of lubricant.

Abstract: A carrier is supported by a case via a bearing. The bearing comprises an inner race, an outer race, rollers, and a retainer. The inner race has a tapered outer peripheral surface, and is fixed to a carrier. The outer race has a tapered inner peripheral surface facing the outer peripheral surface of the inner race, and is fixed to the case. The rollers is disposed between the inner race and the outer race. An end part of the retainer having a larger diameter makes contact with the case via a first member. The larger diameter end part of the retainer makes contact with the case via a second member. By the retainer making contact with the case and the carrier via the first member and the second member, the retainer can reduce friction compared to when making direct contact with the case and the carrier.
