矿用行星减速器输出端与链轮通过花键直接联接,行星结构决定该处轴承只承受径向力,多年来,输出端轴承配置也有许多种形式,但多数与轴承本身结构与设计尺寸有关,没有考虑轴承与密封的关系,近年来,发生多次因轴承窜动造成密封泄漏的情况,逐步改进轴承形式并经过多次试验,调整安装间隙,改善因轴承导致的密封失效问题。 Mine planetary gear reducer output and sprocket directly through the spline, planetary structure where the bearing only radial forces, over the years, the output bearing configuration There are many forms, but most of the bearing structure and design dimensions , No consideration has been given to the relationship between bearing and seal. In recent years, multiple leaks occurred due to bearing movement, and the bearing form was gradually improved. After several tests, the installation clearance was adjusted to improve the sealing failure caused by the bearing.
