摘要： A sleeve bearing for a motor has a lubricant reservoir (16) formed by a high temperature resistant lubricant absorbed into a felt pad. An annular wall (15) extends axially of the motor and supports a part of the reservoir externally of the wall. Four imperforate channels (31 to 34) extend along the internal surface of the wall, tapering so that they are deeper adjacent the sleeve bearing where they open into the reservoir. The width of the channels is about 33% the total circumference of the wall. An O-ring (29) embracing the shaft (2) within the wall throws oil outwardly onto the wall so that it flows along the grooves into the reservoir. A PTFE washer (25) with a grooved surface is mounted on the shaft on the opposite side of the bearing.

摘要： A sleeve bearing assembly for opposite ends of a vertical motor each have a lubricant reservoir (16) formed by a high temperature resistant lubricant absorbed into a felt pad. An oil seal (40, 50) of a high temperature resistant rubber is located below each bearing within an annular wall (15) that extends axially of the motor shaft (2). Wings (41 to 44) on the oil seal project into grooves (31 to 34) in the wall to prevent rotation of the seal. Each seal has an annular nib (46 and 47, 51 and 52) at each end that engage the shaft, forming a rotational seal which impedes downward flow of lubricant along the shaft. A groove (48, 53, 54) extends coaxially around one or both of the nibs to increase its flexibility.

摘要翻译： 用于垂直马达的相对端的套筒轴承组件各自具有由吸收到毡垫中的耐高温润滑剂形成的润滑剂储存器（16）。 耐高温橡胶的油封（40,50）位于沿着电动机轴（2）轴向延伸的环形壁（15）内的每个轴承的下方。 油封上的翼（41至44）突入墙壁上的凹槽（31至34），以防止密封件旋转。 每个密封件在每个端部具有接合轴的环形尖头（46和47,51和52），形成旋转密封件，其阻止润滑剂沿着轴向下流动。 凹槽（48,53,54）围绕笔尖的一个或两个同轴地延伸以增加其柔性。
