【摘要】：基于滚动轴承的动力学理论,建立了双列调心滚子轴承动力学微分方程与摩擦力矩数学模型,采用预估-校正GSTIFF(gear stiff)变步长积分算法求解其动力学微分方程,研究了结构参数和工况参数对双列调心滚子轴承摩擦力矩特性的影响。研究结果表明:较小的内滚道密合度与较大的外滚道密合度有利于降低轴承的摩擦力矩;过大、过小的保持架兜孔曲率半径都不利于轴承摩擦力矩的降低,存在一个合理的保持架兜孔曲率半径使轴承摩擦力矩最小;保持架兜孔间隙对轴承的摩擦力矩影响较小,适当增大保持架引导间隙可有效减小轴承的摩擦力矩;适量的增大双列调心滚子轴承径向游隙有利于降低轴承的摩擦力矩。
[Abstract]:The kinetic theory of rolling bearing based on a double row self-aligning roller bearing friction torque dynamic differential equation and mathematical model, the predictor corrector GSTIFF (gear stiff) variable step integration algorithm to solve the dynamic differential equation, the influence of structural parameters and operating parameters on the friction torque characteristics of double row self-aligning roller bearings. The results show that: the small the raceway density with larger outer raceway density to reduce the friction torque of bearings is too large, too small; the retainer pocket hole radius of curvature is not conducive to the friction torque of the bearings is reduced, there is a reasonable retainer pocket hole radius of curvature of the bearing friction torque minimum retainer pocket; small hole clearance effect on bearing friction torque, increasing friction torque can effectively reduce the bearing cage guide gap increases; the amount of double row spherical roller bearing radial travel The gap is beneficial to reduce the friction torque of the bearing.
