減速機(jī)在原動機(jī)和工作機(jī)或執(zhí)行機(jī)構(gòu)之間起匹配轉(zhuǎn)速和傳遞轉(zhuǎn)矩的作用，是一種相對精密的機(jī)械。使用它的目的是降低轉(zhuǎn)速，增加轉(zhuǎn)矩。它的種類繁多，型號各異，不同種類有不同的用途。

The reducer plays the role of matching speed and transmission torque between the original motive and the working machine or the actuator. It is a relatively precise machine. The pure of using it is to reduce the speed and increase the torque. It has a wide variety of types and different types, and different types have different uses.

減速機(jī)是國民經(jīng)濟(jì)諸多領(lǐng)域的機(jī)械傳動裝置，行業(yè)涉及的產(chǎn)品類別包括了各類齒輪減速機(jī)、行星齒輪減速機(jī)及蝸桿減速機(jī)，也包括了各種專用傳動裝置，如增速裝置、調(diào)速裝置、以及包括柔性傳動裝置在內(nèi)的各類復(fù)合傳動裝置等。

The reducer is a mechanical drive device in many fields of national economy, industry related product categories include all kinds of gear reducer, planetary gear reducer and the worm reducer, also includes a variety of special transmission device, such as accelerating device, device, and a flexible transmission device, transmission device, including various types of composite.

減速機(jī)動力源運轉(zhuǎn)速度 根據(jù)在不同轉(zhuǎn)速條件下對減速機(jī)的試驗表明，隨著減速機(jī)輸入轉(zhuǎn)速的增加，噪聲也將增大。 

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.
