减速机与工作机的联接：减速机直接套装在工作机主轴上，当减速机运转时，作用在减速机箱体上的反力矩，又安装在减速机箱体上的反力矩支架或由其他方法来平衡。机直接相配，另一端与固定支架联接.
The connection between the reducer and the working machine: the reducer is directly installed on the main shaft of the machine, when the reducer operates, the torque acting on the gearbox body is installed on the reverse torque support on the reduction box body or by other methods to balance. The machine is directly matched and the other end is connected with the fixed support.
减速机的作用
1)降速同时提高输出扭矩，扭矩输出比例按步进电机输出乘减速比，但要注意不能超出减速机额定扭矩。
2)速同时降低了负载的惯量，惯量的减少为减速比的平方。大家可以看一下一般电机都有一个惯量数值。
The function of the reducer
1) reduce the speed and increase the output torque at the same time. The ratio of the torque output to the multiplying and decelerating ratio of the stepper motor output, but we must be careful not to exceed the rated torque of the reducer.
2) speed reduces inertia of load at the same time, and inertia reduces to the square of deceleration ratio. As you can see, general motors h***e an inertia value.
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.
