圆锥滚子轴承轴向定位预紧刚度计算

研究轴向定位预紧状态下圆锥滚子轴承的刚度计算方法。首先，由轴向载荷作用下轴承内外圈相对位移及力平衡关系，推导圆锥滚子轴承的轴向刚度计算公式；其次，由轴向定位预紧轴承受径向载荷时各滚子的变形，推导出轴承的径向刚度计算公式；并且，经合理近似给出上述径、轴向刚度公式的简便计算公式，最后，将公式的计算结果同实验数据作对比，表明公式的误差较小，可以实际应用。

Rigidity Calculation of Axial Position Preload Taper Roller Bearings

The rigidity calculation is discussed for tapered roller bearings under axial position preload.First,the calculation formula of axial rigidity is deduced from relative displacement between inner and outer rings and force balance under the axial load.Second,the calculation formula of radial rigidity is deduced according to the deformation of rollers under the radial load with axial position preload.And the simple and convenient calculation formulas are presented after some reasonable.The results show that the difference between the test data is relatively small for engineering application.
