The invention discloses a planetary gear speed reducer for a vehicle steering device. The planetary gear speed reducer comprises an external rotating shaft; an inner rotating shaft is movably connected into the outer rotating shaft; the outer surface of the outer rotating shaft is fixedly connected with a positioning ring; the outer surface of the inner rotating shaft is sleeved with a planet wheel; the outer surface of the planet wheel is meshed with a rotating star wheel; the outer portion of the outer rotating shaft is sleeved with symmetrical protective shells; and the left side faces andthe right side faces of the two protective shells are each fixedly connected with a first fixing block. The invention discloses the planetary gear reducer for the vehicle steering device. The protective shells are disassembled through the cooperation of fixing bolts and nuts; the disassembly efficiency is improved; a clamping groove and a clamping block are separated through a handle, so that theeffect of quickly disassembling the speed reducer is achieved; the trouble of workers is reduced; the working efficiency of maintenance personnel is improved; a driver can be prevented from slipping off during steering through an anti-slip sleeve; and the safety of the driver is improved.

    本发明公开了一种用于车辆转向装置的行星齿轮减速器,包括外旋转轴,所述外旋转轴的内部活动连接有内旋转轴,所述外旋转轴的外表面固定连接有定位圈,所述内旋转轴的外表面套设有行星轮,所述行星轮的外表面啮合有旋转星轮,所述外旋转轴的外部套设有相对称的防护壳,两个所述防护壳的左右两侧面均固定连接有第一固定块。该用于车辆转向装置的行星齿轮减速器,通过固定螺栓和螺母的配合对防护壳进行拆卸,提高拆卸的效率,通过把手把卡槽和卡块进行分离,达到了快速拆卸该减速器的效果,减少了工作人员的麻烦,提高维修人员的工作效率,通过防滑套能够避免驾驶人员在转向的时候发生滑脱,提高驾驶人员的安全性。
