減速機一般用于低轉速大扭矩的傳動設備，把電動機、內燃機或其它高速運轉的動力通過減速機的輸入軸上的齒數少的齒輪嚙合輸出軸上的大齒輪來達到減速的目的，普通的減速機也會有幾對相同原理齒輪達到理想的減速，大小齒輪的齒數之比，就是傳動比。

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.

旋緊緊力螺栓。所有緊力螺栓均需用力矩板手按標明的固定扭力矩數據進行固定和檢查。減速機與機械設備間的正確安裝類同減速機與驅動電機間的正確安裝。關鍵是要必須保證減速機輸出軸與所驅動部分軸同心度一致。

Tighten tight bolt. All tight bolts must be fixed and checked with the fixed torque data marked by the torque plate hand. The correct installation between the reducer and the mechanical equipment is the same as that between the reducer and the driving motor. The key is to ensure that the output shaft of the reducer is cistent with the of the drive shaft.

減速機與工作機的聯接：減速機直接套裝在工作機主軸上，當減速機運轉時，作用在減速機箱體上的反力矩，又安裝在減速機箱體上的反力矩支架或由其他方法來平衡。機直接相配，另一端與固定支架聯接.

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.
