Abstract The load distribution between the rolling elements and raceway is crucial in performance evaluation of rolling element bearings. An experimental method is proposed to determine the load distribution by measuring the strain response at the bearing surface with a notched housing. Finite element analysis shows that the introduction of notches does not affect the load distribution. An experimental system was developed to investigate the load distribution in a cylindrical roller bearing. The experimental static load distribution agrees well with the theoretical calculation. The dynamic load at specific position of load zone reflects the manufacture difference among rollers and dynamic balance of distributing loads. The proposed method provides a possible way for real time load distribution measurement of cylindrical roller bearings.

带有仪表轴承座的圆柱滚子轴承中载荷分布的测量：有限元验证和实验研究

摘要 滚动体与滚道之间的载荷分布是滚动轴承性能评价的关键。提出了一种通过测量带有缺口轴承座的轴承表面的应变响应来确定载荷分布的实验方法。有限元分析表明，缺口的引入不影响载荷分布。开发了一个实验系统来研究圆柱滚子轴承中的载荷分布。实验静载荷分布与理论计算吻合良好。载荷区特定位置的动载荷反映了滚子之间的制造差异和分布载荷的动平衡。该方法为圆柱滚子轴承载荷分布的实时测量提供了一种可能的方法。
