减速机动力源运转速度 根据在不同转速条件下对减速机的试验表明，减速机，随着减速机输入转速的增加，噪声也将增大。 

The experimental study on the structural form of the reducer box shows that the cylindrical box is advantageous to vibration reduction. Under the same other conditi， the noise level of the cylindrical box is 5 dB lower than that of other types of box on average.

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，减速机设备，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 have 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 transmission ratio is.

在减速机家族中，行星减速机以其体积小，减速范围广，减速机工厂，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***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，减速机哪家有， planetary reducer is applied to servo， step and DC transmission systems because of its small 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.
