Speed reducer, hydraulic motor, construction machine, and method for manufacturing speed reducer
The invention relates to a speed reducer, a hydraulic motor, a construction machine and a manufacturing method of the speed reducer. The speed reducer is provided with a sun gear, planetary gears, a carrier, a ring gear, and a thrust plate. Driving force is input to the sun gear. The planetary gear is meshed with the sun gear, and the gear ring is meshed with the planetary gear. The carrier has a supporting shaft that rotatably supports the planetary gear, and a positioning portion is formed on an end surface of a tip end portion of the support shaft. The thrust plate has a portion to be positioned that fits into the positioning portion, and receives a thrust load of the planetary gear by means of an opposing surface that opposes an end surface of the planetary gear in the axial direction. The positioning part is formed by a concave part which is opened at the thrust plate side. The portion to be positioned of the thrust plate is configured from a protruding portion protruding toward the support shaft side and having a cross-section formed so as to correspond to the shape of the recessed portion.
本发明涉及减速器、液压马达、施工机械以及减速器的制造方法。本发明的减速器具有：太阳齿轮、行星齿轮、齿轮架、齿圈以及止推板。向太阳齿轮输入驱动力。行星齿轮与太阳齿轮啮合，齿圈与行星齿轮啮合。齿轮架具有将行星齿轮支承为能够旋转的支承轴，在支承轴的顶端部的端面形成定位部。止推板具有与定位部嵌合的被定位部，借助在轴向上与行星齿轮的端面相对的相对面承受行星齿轮的推力载荷。定位部由在止推板侧开口的凹部构成。止推板的被定位部由朝向支承轴侧突出并且截面形成为与凹部的形状对应的凸部构成。
