摘 要： In the present study, high-speed ball bearings subjected to both axial and radial loads are investigated. This also includes the effect of centrifugal force. Through the geometric analysis of a ball bearing and the force balance, several parameters can be easily obtained, like: the normal forces acting on the contact points; the contact angle at either the inner or the outer raceways that vary with the bearing position angles; bearing stiffness in the axial and radial directions that vary with the cage's angular velocity, etc. Using Hirano's criterion, the conditions for the proper choice of the total deformations in two directions can be identified in order to avoid bearing skidding. The analysis indicates that a more effective way to prevent the bearings from skidding at high angular velocities is to raise the deformation applied in the axial direction. It is the angular velocity of the cage, rather than the load applied in the radial direction that is the dominant factor in the choice of the axial deformation to avoid skidding.

本研究对承受轴向和径向载荷的高速滚动轴承进行了分析，同时考虑了离心力的影响。通过滚珠轴承的几何分析和力平衡分析，可轻松获得多个参数，例如：作用在接触点上的法向力； 内圈或外圈轨道上的接触角，会随轴承位置角度的变化而变化； 轴向和径向方向的轴承刚度随保持架角速度的变化而变化等。根据平野准则，可确定在两个方向上合理选择总变形的条件，以避免轴承打滑。分析表明，防止轴承在高角速度下打滑更有效的方法是增大轴向变形量。在选择轴向变形以避免打滑时，主导因素是保持架的角速度，而非径向载荷。
