一般大型齿轮减速机的齿轮采用铸造加工后都要进行动平衡试验,一些工厂由于条件限制,则以静平衡代之,其效果基本相同。齿轮找静平衡方法很多,但所需工艺装置都较复杂,通用性又差,因此影响了经济效益。利用杠杆原理用钢球作为工具,对齿轮找静平衡,实践证明,精度达到0.02kgfm的要求。用钢球对齿轮找静平衡简便易行,其操作方法: 选择一个直径D大于齿轮轴孔d的钢球,有一定的硬度、椭圆度<3.5μm。再用一块300mm~2表面光滑平整的钢板,并有与钢球相同等级的硬度,将钢板水平放在平台上。把钢球放在钢板中心部位。再把 General large-scale gear reducer gear casting process should be carried out after the dynamic balance test, some factories due to conditions, then the static balance instead, the effect is basically the same. There are many ways to find the balance of gears, but the required process equipment are more complex, versatility and poor, thus affecting the economic benefits. The use of steel ball lever principle as a tool to find the balance of the gear, the practice proved that the accuracy of 0.02kgfm requirements. Steel ball to find the balance of the gear is simple and easy, its operation method: Select a diameter D is greater than the gear shaft d hole d, a certain degree of hardness, ellipticity <3.5μm. Then a piece of 300mm ~ 2 smooth surface of the steel plate, and the ball with the same level of hardness, the plate level on the platform. Place the ball on the center of the plate. Then again
