以FAG 6219 C3轴承为例，使用Hertz理论公式进行深沟球轴承极限轴向载荷的理论计算，并使用RO-MAX软件进一步验证了计算结果，同时总结出深沟球轴承的极限轴向载荷与初始径向游隙之间的变化关系，从而避免轴承在使用过程中接触区超出沟道产生边缘应力集中，为轴承设计提供了参考。%Taking the bearing FAG 621 9C3 as an example,the limit axial load for deep groove ball bearing is theoreti-cally calculated by Hertz theory formula.The calculation results are verified by software ROMAX,the relationship be-tween limit axial load and initial radial clearance for deep groove ball bearing is concluded,thus to avoid edge stress concentration generated by contact zone exceeding raceway during bearing application and provide references for bearing design.
