| 中文摘要: |
| 以渐开线直齿圆柱齿轮为研究对象,建立了对非牛顿条件下考虑热和粗糙度的齿轮供油条件进行分析的润滑模型。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,这三点的膜厚也随之增加,但当其增加到一定程度时,便不再随供油膜厚的变化而变化。说明在非牛顿条件下考虑粗糙度和热之后,供油量不是越大越好,存在一个供油临界点。考虑大齿表面的粗糙度后,数值计算结果显示,粗糙峰使润滑膜压力和膜厚的分布产生振荡,说明齿轮表面的粗糙峰对齿轮的润滑是不利的,但是粗糙度的加入使节点的数值解更接近实际工况。 |

| Under the condition of non-newtonian taking a involute spur gear as research object, a gear microscopic surface pitting lubrication model was established, and the oil condition which joined the roughness and thermal factor was introduced. Based on the multi-grid method, a numerical solution of spur gear oil condition lubrication was obtained. The result shows that with the provided oil film thickness increases, 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 it will not be better as the amount of oil adds, there exists a critical point. Considered the large tooth surface roughness, the numerical results show that asperity leads to the oscillation of the lubricant film thickness and distribution of the pressure, indicating the gear surface roughness is negative for the gear lubrication, the roughness is added to make the numerical solution of the node closer to the actual working conditions. |
