摘要: 以圆柱滚子轴承为模型原始对象,针对其旋转精度中的外圈径向跳动,提出了一种预测仿真的方法。在外圈滚道存在已知圆度误差的条件下,通过C++编程实现了预测外圈径向跳动的仿真算法,并验证了该仿真算法的正确性。根据仿真结果,得到了圆柱滚子轴承外圈径向跳动的变化曲线,并分析了外圈径向跳动与外圈滚道圆度误差谐波阶数、谐波系数之间的关系,并找出了外圈径向跳动与谐波阶数、滚子数三者之间的特殊规律。Abstract: Using a cylindrical roller bearing as original object model,we propose a simulation method for forecasting the radial jump of its outer ring.Under the condition that there exist known roundness errors in the outer ring roll path,we use the C++ program to work out a simulation algorithm for forecasting the radial jump of the outer ring and verify the correctness of the simulation algorithm.The simulation produces the curves for the radial jump of the outer ring of the cylindrical roller bearing.Then we analyze the relationship between the radial jump of the outer ring and the number of orders of harmonic wave of the roundness error in the outer ring roll path and the relationship between the radial jump of the outer ring and the coefficients of the harmonic wave of roundness error.
