文中列出了轴承套圈在磨加工过程中的变形实例。实践证明:套圈在磨加工过程中的变形是很大的。必须从工艺上采取相应的措施。套图变形的原因有下列三方面,1.套圈内的残余应力,2.套圈内部组织的变化,3.夹具的夹紧力和磨削抗力。文中着重阐述了套圈的刚度和几何尺寸的关系。在本文的小结中提出,过去用直径和壁厚的比值D/b作为衡量套圈刚度的方法是不合理的。应该指出的是套图的径向变形与套圈中性半径R的三次方成正比,与壁厚b的三次方成反比,与幅高h成反比。径变系数K_x与弯变系数K_y这一新的概念对正确确定套圈的刚度,估计可能发生变形的大小是很有意义的。
The article lists the deformation of the bearing ring during the grinding process. Practice has proved: ferrule in the deformation process is great. Must take corresponding measures from the craft. There are three reasons for the deformation of the sleeve: 1. Residual stress in the ferrule 2. Changes in the internal structure of the ferrule 3. Clamping force and grinding resistance of the clamp. The paper focuses on the relationship between the stiffness of the ferrule and the geometric dimensions. In the summary of this paper, it is not reasonable to use the ratio of diameter to wall thickness, D / b, as a measure of the stiffness of a ferrule in the past. It should be noted that the radial deformation of the sleeve is proportional to the cube of the ring’s neutral radius R, inversely proportional to the cube of the wall thickness b, and inversely proportional to the height h. The new concept of K_x and K_y makes sense to determine the stiffness of the ferrule and to estimate the size of the deformation that may occur.
