允許輸入法蘭：

不能大于或小于臨級減速機的標準尺寸，如減速機PLE80?的標準法蘭為80mm,其臨級的減速級是PLE60?和PLE120，PLE80?允許法蘭不應小于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?減速機的作用1)降速同時提高輸出扭矩，扭矩輸出比例按步進電機輸出乘減速比，但要注意不能超出減速機額定扭矩。 PLE120, PLE80? The maximum allowable flange should not be less than 60mm, nor greater than 120mm.

對減速機箱體進行共振測試，找出共振位 置，增加適當?shù)慕顥l（板），可以提高箱體的剛度，減少箱體的振動，實現(xiàn)降噪。多級傳動時要求瞬時傳動比的變化盡量小，以保證傳動平穩(wěn)，沖擊及振動小，噪聲低。

By testing the resonance of the reducer box, finding out the resonance  and adding appropriate ribs (plates), the stiffness of the box can be increased, the vibration of the box can be reduced and the noise can be reduced. In multistage transmission, the change of instantaneous transmission ratio should be as small as  to ensure stable transmission, low impact and vibration, and low noise.
