摘要:
Described is a drive unit, in particular for vehicle windscreen wipers, with a shaft (14) projecting out from one end (15) of a bearing housing (13) and a cylindrical plain bearing (16) fitted inside the housing (13) close to the end (15). The plain bearing (16), bearing housing (13) and shaft (14) together define an annular gap (17). The invention calls for a sleeve (25) made of elastic plastic and fitted tightly against the bearing housing (13) to close off the annular gap (17) in front of the plain bearing (16). The end of the sleeve (25) remote from the bearing housing (13) has a radial sealing flange (30) which projects inwards to engage in an annular groove (31) in the shaft (14).
摘要(中):
描述了一种驱动单元,特别是用于车辆挡风玻璃刮水器的驱动单元,具有从轴承箱(13)的一个端部(15)伸出的轴(14)和装配在壳体(13)内的圆柱形滑动轴承(16) 到最后(15)。 滑动轴承(16),轴承壳体(13)和轴(14)共同限定了环形间隙(17)。 本发明要求由弹性塑料制成的套筒(25),并紧密地装配在轴承箱(13)上,以便关闭滑动轴承(16)之前的环形间隙(17)。 远离轴承箱(13)的套筒(25)的端部具有向内突出的径向密封凸缘(30),以接合在轴(14)中的环形槽(31)中。
