安装前，将电机输入轴、***凸台及减速机连接部位的防锈油用或锌钠水擦拭净。其目的是保证连接的紧密性及运转的灵活性，并且防止不必要的磨损。
Before installation, the anti rust oil of the motor input shaft, the itioning protruding platform and the connecting part of the reducer is cleaned with gasoline or zinc sodium water. The pure is to ensure the tightness of the connection and the flexibility of the operation, and to prevent unnecessary wear.
减速机内部齿轮齿形修整（修缘和修根）和齿顶倒角 将齿顶的齿形切削成比正确的渐开曲线略呈凸形。当齿轮齿面受外力产生变形时，可以避免对与之啮合的齿轮产生干涉，并且可以降低噪音，延长齿轮寿命。
The internal gear of the reducer is trimmed (trim and trim) and tooth top chamfering to make the tooth shape of the tooth top convex than the correct involute curve. When the gear tooth surface is deformed by external force, it can ***oid interference to the gears engaged with it, and can reduce noise and prolong the service life of gears.
