中文摘要：
以渐开线直齿圆柱齿轮为研究对象,建立了加入非牛顿和变温因素的齿轮供油条件分析的润滑模型。利用多重网格法,得到了啮合过程中啮入点、节点和啮出点三点在不同供油条件下的弹流数值解。结果表明：起初随着供油膜厚的增加,三点的膜厚也随之增加,但当其增加到一定程度时,三点的膜厚不再随之变化而变化,说明在非牛顿和变温条件下,乏油对齿轮润滑不一定是不利的,而且供油量不是越大越好,存在一供油临界点。
英文摘要：
A gear microscopic surface pitting lubrication model was established,and the oil condition which combined the non-newtonian and thermal factor was introduced.Based on the multi-grid method,a numerical solution of spur gear oil condition lubrication was obtained. The result show that with the provided oil film thickness increasing,the film thickness of the three points also increases.When it is added to a certain degree ,the film thickness will no longer change.The result shows that starvation is not detrimental to the gear as the thermal factor affects,but it will not be better as the amount of oil adds,and there exists a critical point.
