两速行星齿轮装置如图所示,它可用于主传动或进给机构。封闭行星齿轮的壳体A是作为输入传动的皮带轮角。壳体左侧的孔中装有磷青铜轴瓦B,它与一个固定而带凸缘的套筒C是滑动配合。由凸缘套上的肩面和右面锁紧螺母D来限制皮带轮的轴向移动。锁紧螺母是通过螺钉夹紧在长套E上。长 Two-speed planetary gear as shown, it can be used for the main drive or feed mechanism. The housing A enclosing the planet gear is a pulley angle that is driven as input. Phosphor bronze bush B is fitted in the hole on the left side of the housing, which is in sliding fit with a fixed, flanged sleeve C. The axial movement of the pulley is limited by the shoulder on the flange and the lock nut D on the right. The lock nut is clamped to the long sleeve E by a screw. long
