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 pure 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.
在减速机家族中，行星减速机以其体积小，减速范围广，精度高等诸多有点，而被应用于伺服、步进、直流等传动系统中。其作用就是在保证精密传动下，主要被用来降低转速增大扭矩和降低负载/电机的转动惯量比。
In reducer family, planetary reducer is applied to servo, step and DC tran***ission systems because of its ***all volume, wide range of deceleration and high accuracy. Its role is to ensure the precision drive, mainly used to reduce the rotational speed to increase the torque and reduce the load / motor inertia ratio.
安装前确认电机和减速机是否完好无损，并且严格检查电机与减速机相连接的各部位尺寸是否匹配，这里是电机的***凸台、输入轴与减速机凹槽等尺寸及配合公差。
Before installation, confirm whether the motor and reducer are in good condition, and strictly check whether the size of each part of the motor connected to the reducer is match. Here is the size and fit tolerance of the motor"s locating lug, input shaft and reducer groove.
