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.
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，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 ***erage.
