减速机一般用于低转速大扭矩的传动设备，把电动机、内燃机或其它高速运转的动力通过减速机的输入轴上的齿数少的齿轮啮合输出轴上的大齿轮来达到减速的目的，普通的减速机也会有几对相同原理齿轮达到理想的减速，大小齿轮的齿数之比，就是传动比。

Reducer is generally used in driving equipment of low speed high torque, large gear gear output shaft power motor, internal combustion engine or other high speed running through the reducer input shaft less number of teeth on the reducer to achieve the purpose of general reducer will h***e several pairs of the same principle to achieve the ideal effect of gear reducer. The size of the number of teeth of the gear ratio, the tran***ission ratio is.

当选用斜齿轮减速机时有以下几点需要注意：

允许输入轴径：减速机的输入轴孔与电机输出轴一般是通过一个厚度可以变化的套环来连接的。当不加套环时减速机输入轴孔为高值。

When choosing a helical gear reducer, there are several points to be paid attention to:

Allowable diameter

The input shaft of the reducer and the output shaft of the motor are generally connected by a sleeve that can be changed by a thickness. The input shaft hole of the reducer is the maximum when the ring is not added.

减速机的种类：一般的减速机有斜齿轮减速机(包括平行轴斜齿轮减速机、蜗轮减速机、锥齿轮减速机等等)、行星齿轮减速机、摆线针轮减速机、蜗轮蜗杆减速机、行星摩擦式机械无级变速机等等。

Type of reducer

The general reducer has helical gear reducer (including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc.), planetary gear reducer, cycloid pin reducer, worm gear reducer, planetary friction mechanical stepless speed change machine and so on.
