减速机与工作机的安装关系：为了避免工作机主轴挠曲及在减速机轴承上产生附加力，减速机与工作机之间的距离，在不影响正常的工作的条件下应尽量小，其值为5-10mm。
The relatihip between the reducer and the working machine is: to ***oid 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 ***all as sible without affecting the normal working conditi, and its value is 5-10mm.
降低减速机运转时的齿轮传动噪声已成为行业内的重要研究课题，国内外不少学者都把齿轮传动中轮齿啮合刚度的变化看成是齿轮动载、振动和噪声的主要因素。用修形的方法，使其动载荷及速度波动减至小，以达到降低噪声的目的。减速机的种类：一般的减速机有斜齿轮减速机(包括平行轴斜齿轮减速机、蜗轮减速机、锥齿轮减速机等等)、行星齿轮减速机、摆线针轮减速机、蜗轮蜗杆减速机、行星摩擦式机械无级变速机等等。这种方法在实践中证明是一种较有效的方法。
Reducing the gear tran***ission 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.
减速机内部齿轮精度等级 设计减速机时，设计者往往从经济因素考虑，尽可能比较经济的确定齿轮精度等级，忽略精度等级是齿轮产生噪声与侧隙的标记。
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.
减速机内部齿轮宽度 在减速机传动空间允许时，增加齿轮宽度，可以减少恒定扭矩下的单位负荷。降低轮齿挠曲，减少噪声激励，从而降低传动噪声。
The width of the internal gear of the reducer can be increased when the tran***ission space of the reducer is allowed, so that the unit load under ctant torque can be reduced. Reduce gear deflection, reduce noise excitation, thereby reducing tran***ission noise.
