行星齿轮机构和变速器
摘要：
本发明提供行星齿轮机构和变速器，其通过提高构成部件间的追随性来抑制动作时的振动和噪音。在行星齿轮机构(10)中，特征在于具有：太阳齿轮(11)，其配设在旋转轴(61)上；多个小齿轮(12)；行星架(13)，其支承多个小齿轮(12)；齿圈(15)，其在行星架(13)的外径侧与小齿轮(12)啮合；以及壳体(18)，其在齿圈(15)的外径侧保持该齿圈(15)，齿圈(15)能够相对于壳体(18)在旋转轴(61)的轴向上滑动，在行星架(13)的外径侧端部(13G)具有载荷传递部件(20)，该载荷传递部件(20)与齿圈(15)的内径侧端部抵接，并且将行星架(13)和齿圈(15)保持成能够相对旋转，将来自齿圈(15)的所述轴向的载荷传递至行星架(13)。
摘要（英）：

A planetary gear mechanism has a sun gear disposed to a rotating shaft, a plurality of pinion gears, a carrier supporting the plurality of the pinion gears, a ring gear meshing with the pinion gear on the outer diameter side of the carrier and a case holding the ring gear on the outer diameter side thereof. The ring gear is slidable in the axial direction of the rotating shaft with respect to the case. The planetary gear mechanism has a load transmission member abutting to an inner diameter side end portion of the ring gear and holding the carrier and the ring gear so as to be relatively rotatable. The load transmission member transmits an axial load from the ring gear to the carrier.
