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(xiàn)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.

當選用斜齒輪減速機時有以下幾點需要注意：

允許輸入軸徑：減速機的輸入軸孔與電機輸出軸一般是通過一個厚度可以變化的套環(huán)來連接的。當不加套環(huán)時減速機輸入軸孔為高值。

When choosing a helical gear reducer, there are several points to be paid attention to:

Allowable diameter

The input shaft of the reducer and the output shaft of the motor are generally connected by a sleeve that can be changed by a thickness. The input shaft hole of the reducer is the maximum when the ring is not added.

允許輸入法蘭：

不能大于或小于臨級減速機的標準尺寸，如減速機PLE80?的標準法蘭為80mm,其臨級的減速級是PLE60?和PLE120，PLE80?允許法蘭不應小于60mm,也不能大于120mm。

Allow input flange

It can't be greater than or less than the standard  of the reducer. For example, the standard flange of reducer PLE80 is 80mm, and the deceleration stage of its reducer is PLE60?China'sspeedreducerindustryhasbeendevelopingfornearly40years。 PLE120, PLE80? The maximum allowable flange should not be less than 60mm, nor greater than 120mm.

減速機內部齒輪的齒距和壓力角 小齒距能保證有較多的輪齒同時接觸，齒輪重疊增多，減少單個齒輪撓曲，降低傳動噪聲，提高傳動精度。較小的壓力角由于齒輪接觸角和橫六角空心磚模具向重疊比都比較大，因此運轉噪聲小、精度高。

The tooth distance of the gear in the reducer and the small pitch of the pressure angle can ensure that there are more teeth at the same time, the overlap of the gear is increased, the deflection of the single gear is reduced, the transmission noise is reduced, and the transmission precision is improved. The smaller pressure angle is due to the larger contact ratio between the gear contact angle and the six corners of the hollow brick mold, so the running noise is small and the accuracy is high.
