摘　　要：突缘叉耳孔直径尺寸、卡簧槽距尺寸对十字轴弯曲应力、接触应力影响很大,协调确定这2个尺寸可提高万向节寿命。传动轴突缘叉耳孔中心高尺寸,对十字轴总成烧蚀失效有很大影响,通过降低中心高尺寸,减小弯矩对突缘叉两耳的作用,可保证两耳孔轴线的同轴度,保证十字轴总成滚针轴承的径向间隙,降低十字轴总成烧蚀失效率。The diameter of snap rings and the dimension across ears are very important to the bending stress and the contact stress. The coordination of the two dimensions can improve the life of the universal joint. The center to face dimension of the snap rings has great influence to the cross assembly ablation. Decreasing the snap rings＇ center to face dimension and the bending moment to the snap rings can make the snap rings stay concentric, keep the radial clearance of the needle bearing of cross assembly and decrease the failure rate of the cross assembly ablation.
