齒輪減速機(jī)具有體積小，傳遞扭矩大的特點(diǎn)。齒輪減速機(jī)在模塊組合體系基礎(chǔ)上設(shè)計(jì)制造，有的電機(jī)組合、安裝形式和結(jié)構(gòu)方案，傳動(dòng)比分級(jí)細(xì)密，滿足不同的使用工況，實(shí)現(xiàn)機(jī)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(dāng)選用斜齒輪減速機(jī)時(shí)有以下幾點(diǎn)需要注意：

允許輸入軸徑：減速機(jī)的輸入軸孔與電機(jī)輸出軸一般是通過(guò)一個(gè)厚度可以變化的套環(huán)來(lái)連接的。當(dāng)不加套環(huán)時(shí)減速機(jī)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(jí)減速機(jī)的標(biāo)準(zhǔn)尺寸，如減速機(jī)PLE80?的標(biāo)準(zhǔn)法蘭為80mm,其臨級(jí)的減速級(jí)是PLE60?和PLE120，PLE80?允許法蘭不應(yīng)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(jī)內(nèi)部齒輪的齒距和壓力角 小齒距能保證有較多的輪齒同時(shí)接觸，齒輪重疊增多，減少單個(gè)齒輪撓曲，降低傳動(dòng)噪聲，提高傳動(dòng)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(yùn)轉(zhuǎn)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.
