減速機與工作機的安裝關系：為了避免工作機主軸撓曲及在減速機軸承上產(chǎn)生附加力，減速機與工作機之間的距離，在不影響正常的工作的條件下應盡量小，其值為5-10mm。

The relatihip between the reducer and the working machine is: to avoid the additional force of the spindle and the additional bearing on the reducer bearing, the distance between the reducer and the working machine should be as small as sible without affecting the normal working conditi, and its value is 5-10mm.

減速機的種類：一般的減速機有斜齒輪減速機(包括平行軸斜齒輪減速機、蝸輪減速機、錐齒輪減速機等等)、行星齒輪減速機、擺線針輪減速機、蝸輪蝸桿減速機、行星摩擦式機械無級變速機等等。

Type of reducer

The general reducer has helical gear reducer (including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc.), planetary gear reducer, cycloid pin reducer, worm gear reducer, planetary friction mechanical stepless speed change machine and so on.

減速機內(nèi)部齒輪精度等級 設計減速機時，設計者往往從經(jīng)濟因素考慮，盡可能比較經(jīng)濟的確定齒輪精度等級，忽略精度等級是齒輪產(chǎn)生噪聲與側(cè)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.

減速機內(nèi)部齒輪變位系數(shù)選擇 正確合理選擇變位系數(shù)，不但可以湊合中心距，避免齒輪根切，保證滿足同心條件，改善齒輪的傳動性能和提高其承載能力及提高齒輪的使用壽命，還可以有效控制 側(cè)隙、溫升與噪聲。

The change coefficient of gear displacement coefficient in the reducer is selected correctly and reasonably. It can not only make the center distance, avoid the gear cutting, meet the conditi, improve the transmission performance of the gear and improve its bearing capacity and improve the service life of the gear, but also can effectively the side gap, temperature rise and noise.
