齒輪減速機具有體積小，傳遞扭矩大的特點。齒輪減速機在模塊組合體系基礎(chǔ)上設(shè)計制造，有的電機組合、安裝形式和結(jié)構(gòu)方案，傳動比分級細(xì)密，滿足不同的使用工況，實現(xiàn)機電一體化。

Gear reducer has the characteristics of small volume and large torque transmission. Gear reducer is designed and manufactured on the basis of modular combination system. There are very many motor combinati, installation forms and structural schemes. The transmission ratio is fine and classified to meet working conditi and achieve mechanical and electrical integration.

在減速機家族中，行星減速機以其體積小，減速范圍廣，精度高等諸多有點，而被應(yīng)用于伺服、步進(jìn)、直流等傳動系統(tǒng)中。其作用就是在保證精密傳動下，主要被用來降低轉(zhuǎn)速增大扭矩和降低負(fù)載/電機的轉(zhuǎn)動慣量比。

In reducer family, planetary reducer is applied to servo, step and DC transmission systems because of its small volume, wide range of deceleration and high accuracy. Its role is to ensure the precision drive, mainly used to reduce the rotational speed to increase the torque and reduce the load / motor inertia ratio.

當(dāng)選用斜齒輪減速機時有以下幾點需要注意：

允許輸入軸徑：減速機的輸入軸孔與電機輸出軸一般是通過一個厚度可以變化的套環(huán)來連接的。當(dāng)不加套環(huán)時減速機輸入軸孔為高值。

When choosing a helical gear reducer, there are several points to be paid attention to:

Allowable diameter

The input shaft of the reducer and the output shaft of the motor are generally connected by a sleeve that can be changed by a thickness. The input shaft hole of the reducer is the maximum when the ring is not added.
