在電機與減速機連接前，應先將電機軸鍵槽與緊力螺栓垂直。為保證受力均勻，先將任意對角位置的安裝螺栓旋上，但不要旋緊，再旋上另外兩個對角位置的安裝螺栓后逐個旋緊四個安裝螺栓。

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.

降低減速機運轉時的齒輪傳動噪聲已成為行業(yè)內的重要研究課題，國內外不少學者都把齒輪傳動中輪齒嚙合剛度的變化看成是齒輪動載、振動和噪聲的主要因素。用修形的方法，使其動載荷及速度波動減至小，以達到降低噪聲的目的。這種方法在實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 在選擇用不同結構形式的齒輪時，對其特定結構建立聲輻射模型，進行動力學分析，對齒輪傳動系統(tǒng)噪聲進行預先評估。以便根據使用者的不同要求（使用場所，是 否無人操作，是否在城區(qū)內，地上、地下建筑物有無特定要求，是否有噪聲防護，或無其他特定要求）去滿足。減速機內部齒輪寬度在減速機傳動空間允許時，增加齒輪寬度，可以減少恒定扭矩下的單位負荷。

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).
