允许输入法兰：

不能大于或小于临级减速机的标准尺寸，减速机生产厂家，如减速机PLE80?的标准法兰为80mm，其临级的减速级是PLE60?和PLE120，减速机，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? PLE120， PLE80? The maximum allowable flange should not be less than 60mm， nor greater than 120mm.

减速机与工作机的联接：减速机直接套装在工作机主轴上，减速机设备，当减速机运转时，作用在减速机箱体上的反力矩，又安装在减速机箱体上的反力矩支架或由其他方法来平衡。机直接相配，另一端与固定支架联接.

The connection between the reducer and the working machine: the reducer is directly installed on the main shaft of the machine， when the reducer operates， the torque acting on the gearbox body is installed on the reverse torque support on the reduction box body or by other methods to balance. The machine is directly matched and the other end is connected with the fixed support.

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，减速机哪家有，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.
