【摘要】：根据圆柱滚子轴承各零件间的运动关系及几何关系,建立了轴承外圈径向跳动数学模型;分析了轴承外圈径向跳动的算法原理,并对轴承的运动过程进行数值仿真;在不考虑轴承内、外圈滚道和滚子圆度误差的情况下,研究了滚子直径误差及滚子排布方式对轴承外圈径向跳动的影响。结果表明:当两个滚子直径误差均为-1.5μm时,有误差的两个滚子相邻排布对轴承外圈的径向跳动有较大影响。当多个滚子直径误差相同且相邻排布时,轴承外圈的径向跳动相等。
[Abstract]:According to the kinematic and geometric relations of the parts of the cylindrical roller bearing, the mathematical model of radial runout of the outer ring of the bearing is established, the arithmetic principle of the radial runout of the outer ring of the bearing is analyzed, and the movement process of the bearing is simulated numerically. In this paper, the influence of roller diameter error and roller arrangement on radial runout of bearing outer ring is studied without considering the inner bearing, outer ring raceway and roller roundness error. The results show that when the diameter error of two rollers is -1.5 渭 m, The adjacent arrangement of two rollers with errors has a great influence on the radial runout of the outer ring of the bearing, and the radial runout of the outer ring of the bearing is equal when the error of the diameter of multiple rollers is the same and the adjacent arrangement of the roller is the same.
