摘要
针对角接触球轴承的接触角、轴向力以及轴承刚度之间的关系问题,通过对轴承建立静力平衡方程,对具有不同接触角(其它参数相同)的轴承进行刚度研究。研究表明:在相同轴向力作用下,轴承自由接触角越大,其轴向刚度越大,但轴向位移、径向刚度以及刚度比值(径向刚度/轴向刚度)都越来越小;在相同接触角情况下,轴向力越大,其轴向位移、轴向刚度和径向刚度都越来越大,但其刚度比值会越来越小。
Aiming at the relationship among contact angle, axial force and stiffness of angular contact ball bearing, the paper studies the stiffness of the bearings with different contact angles（the other parameters are same） by establishing the static equilibrium equation. Research shows that, under the same axial force, the bigger the free contact angle is, the bigger the axial rigidity is, but the axial displacement, radial stiffness and stiffness ratio（radial stiffness/axial stiffness） are getting smaller. Under the same contact angle, when the axial force is bigger, the axial displacement, the axial stiffness and the radial rigidity will be greater, but the stiffness ratio will be smaller..
