本研究的目的是研究空化喷丸对钢齿轮滚动接触疲劳寿命的影响。利用轧辊试验机和齿轮试验机对不同条件下喷丸处理的轧辊和齿轮进行了疲劳试验。经空化喷丸处理后，轧辊和齿轮的表面硬度和表面残余压应力均有所提高。另一方面，表面粗糙度并没有增加太多。结果表明，大多数喷丸处理的滚子和齿轮的疲劳寿命都高于未喷丸的滚子和齿轮。特别是在高速水射流下采用改进型喷嘴，显著提高了疲劳寿命，获得了更好的喷丸效果。由此可见，空化喷丸有利于提高钢齿轮的疲劳寿命，因为喷丸效果是在表面粗糙度增加较少的情况下获得的。
The purpose of this study is to investigate the effect of cavitation peening on the rolling contact fatigue life of steel gears. The steel rollers and gears cavitation-peened under different conditions were fatigue-tested using a roller testing machine and a gear testing machine. After the cavitation peening, the surface hardness and the surface compressive residual stress of the steel rollers and gears were increased. On the other hand, the surface roughness was not increased so much. As a result, the fatigue life of most cavitation-peened rollers and gears was longer than that of the non-peened ones. In particular, the fatigue life was significantly improved by using a modified nozzle for a high-speed water jet to obtain a greater peening effect. It is suggested from these that the cavitation peening is good for the increase in fatigue life of steel gears, because the peening effect is obtained with less increase of the surface roughness.
