減速機(jī)是國民經(jīng)濟(jì)諸多領(lǐng)域的機(jī)械傳動(dòng)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(dòng)裝置，如增速裝置、調(diào)速裝置、以及包括柔性傳動(dòng)裝置在內(nèi)的各類復(fù)合傳動(dòng)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.

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

安裝前確認(rèn)電機(jī)和減速機(jī)是否完好無損，并且嚴(yán)格檢查電機(jī)與減速機(jī)相連接的各部位尺寸是否匹配，這里是電機(jī)的定位凸臺(tái)、輸入軸與減速機(jī)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.

減速機(jī)內(nèi)部齒輪精度等級(jí) 設(shè)計(jì)減速機(jī)時(shí)，設(shè)計(jì)者往往從經(jīng)濟(jì)因素考慮，盡可能比較經(jīng)濟(jì)的確定齒輪精度等級(jí)，忽略精度等級(jí)是齒輪產(chǎn)生噪聲與側(cè)隙的標(biāo)記。

When the reducer is designed in the gear precision grade of the reducer, the designers often cider the economic factors as much as  to determine the gear precision level as much , and ignore the precision grade as the mark of the gear noise and the backlash.
