允许输入法兰：
不能大于或小于临级减速机的标准尺寸，如减速机PLE80?的标准法兰为80mm,其临级的减速级是PLE60?和PLE120，PLE80?允许法兰不应小于60mm,也不能大于120mm。
Allow input flange
It can"t be greater than or less than the standard of the reducer. For example, the standard flange of reducer PLE80 is 80mm, and the deceleration stage of its reducer is PLE60?Reducegeardeflection,reducenoiseexcitation,therebyreducingtran***issionnoise。 PLE120, PLE80? The maximum allowable flange should not be less than 60mm, nor greater than 120mm.
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.
