59、针轴承的疲劳劳寿命试验研研究。试验结结果表明，对对数轮廓滚针针的润滑状态态和承载能力力明显好于相相交圆弧修形形滚针；凸度度量不足会导导致边缘效应应，但凸度量量过大同样会会降低承载能能力,即某确确定工况下凸凸度量存在最最优值；对于于凸度量相同同的一组滚针针，高速轻载载工况下的承承载能力明显显好于低速重重载工况，这这与高速轻载载工况下的润润滑状态较好好有关。主题词：凸度滚滚针轴承 摆动 疲疲劳寿命Compariison TTests of Osscillaation Fatiigue LLife ffor Cardaan Joiint Conveex Neeedle RRollerrShen Xu
