減速機是國民經濟諸多領域的機械傳動裝置，行業(yè)涉及的產品類別包括了各類齒輪減速機、行星齒輪減速機及蝸桿減速機，也包括了各種專用傳動裝置，如增速裝置、調速裝置、以及包括柔性傳動裝置在內的各類復合傳動裝置等。

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.

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，而被應用于伺服、步進、直流等傳動系統(tǒng)中。其作用就是在保證精密傳動下，主要被用來降低轉速增大扭矩和降低負載/電機的轉動慣量比。

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.

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.

減速機內部齒輪精度等級 設計減速機時，設計者往往從經濟因素考慮，盡可能比較經濟的確定齒輪精度等級，忽略精度等級是齒輪產生噪聲與側隙的標記。

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.
