摘要： An epicyclic gear system (A) includes a sun gear (2), a ring gear (4) located around the sun gear (2) and planet pinions (6) located between the sun and ring gears (2,4). The planet pinions (6) rotate on a carrier (8) that includes flexpins (20) that are cantilevered from a wall (12) of the carrier (8) and sleeves (22) that are attached to the remote ends of the flexpins (20) and extend back over the flexpins (20) to create a double cantilever. Bearings (24) support the planet pinions (6) on the sleeves (22) so that the planet pinions (6) rotate about the flexpins (20). The double cantilever enables the flexpins (2) to flex such that the axes (Y) of the planet pinions (6) remain parallel to the common axis (X) of the sun and ring gears (2, 4). Each sleeve (22) has an integrated bearing race (44) and a bearing seat (42) that carries a separate bearing race (60). The sleeve (22) is easily detached from its flexpin (20) and the separate race (60) is easily removed from the sleeve (22) to disassemble the bearing (24) and remove the planet pinion (6).

摘要： A backing ring (R) that serves to back an antifriction bearing (B) on the journal (2) of a rail car axle (A) includes an annular body (36, 52, 66, 88, 98, 118, 136, 160, 170, 188, 214, 234, 254) that seats against a fillet (6) that is located at the end of the journal and also a lip (46, 56, 70, 90, 100, 120, 138, 162, 172, 190, 216, 236, 268) that projects over a larger dust guard diameter (4) that is located on the axle immediately beyond the fillet. In addition, the backing ring includes a stabilizing element (38, 54, 68, 96, 102, 122, 142, 166, 178, 194, 224, 242, 256) which cooperates with the lip and with the dust guard diameter to lessen the tendency of the annular body to work against the fillet and create a fretting wear when the journal undergoes cyclic flexures. The stabilizing element accommodates dust guard diameters of varying size. The stabilizing element may also establish a seal between the lip and the dust guard diameter.

摘要： A locating bearing assembly (10) is provided that optimizes load distribution between bearing rows and for all rolling elements within the rows in either positive or negative torque conditions, by combining a single row tapered roller bearing with an angular contact ball bearing. The outer race (60) for the ball bearing is preloaded by a spring element (72) to prevent the balls (26) from floating freely between the ball bearing's inner and outer raceways (16, 64). This will insure that the balls (26) are always sufficiently loaded to roll along a single axis which is off set from the radial direction. The use of the single row tapered bearing and the preloaded angular contact ball bearing provides for a locating bearing assembly ("LBA") in which the ball bearing supports only reversing axial loads. All radial loads are borne by the tapered roller bearing and transmitted to the bearing assembly housing (30).
摘要翻译：提供了一种定位轴承组件（10），其通过将单列圆锥滚子轴承与角接触球轴承组合来优化轴承列之间的负载分布和用于正或负扭矩条件下的行内的所有滚动元件。用于球轴承的外圈（60）由弹簧元件（72）预加载，以防止球（26）在滚珠轴承的内滚道（16,64）之间自由浮动。这将确保球（26）总是被充分负载以沿着从径向方向偏离的单个轴滚动。使用单列锥形轴承和预加载的角接触球轴承提供了一种定位轴承组件（“LBA”），其中滚珠轴承仅支承反向轴向载荷。所有的径向载荷由圆锥滚子轴承承载并传递到轴承组件壳体（30）。
