润滑剂保持组件
摘要：
本发明涉及一种润滑剂保持组件。所述润滑剂保持组件与一电动机一起使用以防止润滑剂从电动机的一自备润滑剂贮蓄槽中流失。所述润滑剂保持组件包括一安装在电动机轴上的止推轴环(70)，和一环绕止推轴环(70)的轴承盖(72)，其中止推轴环(70)具有一将沿电动机轴泄漏的润滑剂径向向外朝向轴承盖(72)抛射的环形法兰(82)。轴承盖(72)具有一倾斜内表面(110)，该内表面(110)将从止推轴环的环形法兰(82)抛出的润滑剂偏转回电动机内部并使该润滑剂朝向所述润滑剂贮蓄槽流动。在电动机轴上还设置有一与所述止推轴环相邻的止推垫圈(76)，该止推垫圈防止润滑剂在电动机轴与止推轴环的交界面之间沿电动机轴发生泄漏。止推垫圈(76)和止推轴环(70)具有互补性的构造，能够将止推垫圈(76)与止推轴环(70)相邻地保持在所述电动机轴上适合的位置中。
摘要（英）：

A lubricant retention assembly is employed with an electric motor to prevent the loss of lubricant from a self contained lubricant reservoir of the motor. The lubricant retention assembly includes a thrust collar (70) mounted on the motor shaft and a bearing cap (72) surrounding the thrust collar (70), where the thrust collar (70) has an annular flange (82) that throws lubricant leaking along theshaft radially outwardly toward the bearing cap (72). The bearing cap (72) has an angled interior(110) surface that deflects the lubricant thrown from the annular flange (82) of the thrust collar back into the motor interior and toward the lubricant reservoir. A thrust washer (76) is also provided on the shaft adjacent the thrust collar and prevents lubricant leakage along the shaft between the interface of the shaft and the thrust collar. The thrust washer (76) and thrust collar (70) have complementary configurations that maintain the thrust washer (76) in position on the shaft adjacent the thrust collar (76).
