减速机在原动机和工作机或执行机构之间起匹配转速和传递转矩的作用，是一种相对精密的机械。使用它的目的是降低转速，增加转矩。它的种类繁多，型号各异，不同种类有不同的用途。
The reducer plays the role of matching speed and tran***ission torque between the original motive and the working machine or the actuator. It is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It has a wide variety of types and different types, and different types h***e different uses.
在电机与减速机连接前，应先将电机轴键槽与紧力螺栓垂直。为保证受力均匀，先将任意对角位置的安装螺栓旋上，但不要旋紧，再旋上另外两个对角位置的安装螺栓***后逐个旋紧四个安装螺栓。
Before connecting the motor to the reducer, the key slot of the motor shaft should be perpendicular to the tightening bolt first. To ensure uniform force, screw the mounting bolts at any diagonal position first, but do not tighten them. Then screw the mounting bolts on the other two diagonal positi***, and tighten the four mounting bolts one by one.
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.
