For the improvement of rolling fatigue durability of gears and rolling bearings, the effects of plastic deformation under the local high contact pressure due to end contact or micro size contact on rolling fatigue were explained. (1) The rolling fatigue limit at contact end is depended on the contact width after plastic deformation. (2) The position of rolling fatigue pit initiation is the minimum oil film thickness zone under mixed lubrication condition. (3) Rolling fatigue limit is not influenced by contact size and stress volume under the mixed lubrication condition. The design concept for rolling contact surfaces under plastic contact condition is explained based on the results as above.

为了提高齿轮和滚动轴承的滚动疲劳寿命，阐述了端部接触或微尺寸接触引起的局部高接触压力下的塑性变形对滚动疲劳的影响。(1)接触端的滚动疲劳极限取决于塑性变形后的接触宽度。(2)在混合润滑条件下，滚动疲劳坑萌生的位置是最小油膜厚度区。(3)在混合润滑条件下，滚动疲劳极限不受接触尺寸和应力体积的影响。在此基础上，阐述了塑性接触条件下滚动接触面的设计思想。
