Analysis for the Shear Stress Distribution at a Roller Surface in the Thermal EHL in Heavily loaded Point Contacts
Pages: 91-93
Year: Issue:  6
Journal: Journal of Mechanical Transmission

Keyword:  轴承剪应力分布弹流润滑点接触;
Abstract: 对HKD-1型航空润滑油进行了重载点接触热弹流计算和滚子表面剪应力分析,并进行了试验验证.结果表明:重载情况下,润滑油的非牛顿特性较显著.滚子表面的剪应力随滑滚比的增加而增大,各种模型下得到的剪应力分布形状相似.采用Evans-Johnson模型预测的剪应力较准确,采用Newton模型预测剪应力误差较大,滑滚比较大时,Newton模型对剪应力的预测失真.
