摘要: In a gear chamber 10, a sealing member 21 is attached to a rotary shaft 12 of an electric motor 11, and a grease return part 21a is provided on this sealing member 21. Thus, grease raked by a helical gear 12a is blown off diagonally forward with respect to a radial direction as a result of a centrifugal force, and it is possible to prevent the grease from leaking out of a ball bearing 20.
摘要翻译: 在齿轮室10中,密封构件21附接到电动机11的旋转轴12,并且在该密封构件21上设置润滑脂返回部21a。因此,由斜齿轮12a斜接的油脂被对角地吹走 作为离心力的结果,相对于径向向前方,能够防止润滑脂从滚珠轴承20泄漏出来。
