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上設計制造，有的電機組合、安裝形式和結構方案，傳動比分級細密，滿足不同的使用工況，實現機電一體化。

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.

安裝前確認電機和減速機是否完好無損，并且嚴格檢查電機與減速機相連接的各部位尺寸是否匹配，這里是電機的定位凸臺、輸入軸與減速機凹槽等尺寸及配合公差。

Before installation, confirm whether the motor and reducer are in good condition, and strictly check whether the size of each part of the motor connected to the reducer is match. Here is the size and fit tolerance of the motor's locating lug, input shaft and reducer groove.

減速器是一種由封閉在剛性殼體內的齒輪傳動、蝸桿傳動、齒輪-蝸桿傳動所組成的獨立部件，常用作原動件與工作機之間的減速傳動裝置 。在原動機和工作機或執(zhí)行機構之間起匹配轉速和傳遞轉矩的作用，在現代機械中應用極為廣泛。

The reducer is an independent component  of gear transmission, worm drive and gear worm drive enclosed in a rigid shell. It is often used as a deceleration between the original and the working machines. The matching speed and transfer torque between prime movers and working machines or actuators are widely applied in modern machines.

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。

2)速同時降低了負載的慣量，慣量的減少為減速比的平方。大家可以看一下一般電機都有一個慣量數值。

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 have an inertia value.
