在電機(jī)與減速機(jī)連接前，應(yīng)先將電機(jī)軸鍵槽與緊力螺栓垂直。為保證受力均勻，先將任意對(duì)角位置的安裝螺栓旋上，但不要旋緊，再旋上另外兩個(gè)對(duì)角位置的安裝螺栓后逐個(gè)旋緊四個(gè)安裝螺栓。

Before connecting the motor to the reducer, the key slot of the motor shaft should be perpendicular to the tightening bolt first. To ensure uniform force, screw the mounting bolts at any diagonal ition first, but do not tighten them. Then screw the mounting bolts on the other two diagonal iti, and tighten the four mounting bolts one by one.

降低減速機(jī)運(yùn)轉(zhuǎn)時(shí)的齒輪傳動(dòng)噪聲已成為行業(yè)內(nèi)的重要研究課題，國(guó)內(nèi)外不少學(xué)者都把齒輪傳動(dòng)中輪齒嚙合剛度的變化看成是齒輪動(dòng)載、振動(dòng)和噪聲的主要因素。用修形的方法，使其動(dòng)載荷及速度波動(dòng)減至小，以達(dá)到降低噪聲的目的。這種方法在實(shí)踐中證明是一種較有效的方法。Thesizeofthenumberofteethofthegearratio,thetransmissionratiois。

Reducing the gear transmission noise of the reducer has become  research topic in the industry. Many scholars both at home and abroad regard the change of gear tooth meshing stiffness as the main factor of gear dynamic load, vibration and noise. The method of modification is used to minimize the dynamic load and speed fluctuation in order to reduce noise. This method is proved to be a more effective method in practice.

齒輪聲輻射特征分析 在選擇用不同結(jié)構(gòu)形式的齒輪時(shí)，對(duì)其特定結(jié)構(gòu)建立聲輻射模型，進(jìn)行動(dòng)力學(xué)分析，對(duì)齒輪傳動(dòng)系統(tǒng)噪聲進(jìn)行預(yù)先評(píng)估。以便根據(jù)使用者的不同要求（使用場(chǎng)所，是 否無(wú)人操作，是否在城區(qū)內(nèi)，地上、地下建筑物有無(wú)特定要求，是否有噪聲防護(hù)，或無(wú)其他特定要求）去滿(mǎn)足。減速機(jī)內(nèi)部齒輪寬度在減速機(jī)傳動(dòng)空間允許時(shí)，增加齒輪寬度，可以減少恒定扭矩下的單位負(fù)荷。

The acoustic radiation characteristic analysis of gear in the selection of gear with different structure forms, set up the acoustic radiation model to its specific structure, carry on the dynamic analysis, and evaluate the gear transmission system noise in advance. In order to meet the users'  requirements (use sites, unmanned operati, whether there are specific requirements in the urban area, ground or underground buildings, noise protection, or other specific requirements).
