摘要
通过Reynolds方程讨论了润滑油膜的主要形成机理,分析了滑移型三叉式联轴器主要配合表面在摩擦学方面的结构缺陷并提出了新型抗磨损结构。针对这一结构,进行了受力分析并使用无限长假设获得了主要配合表面的用于数值分析的几何模型。最后,在等温牛顿流体条件下,列出了用于数值分析的控制方程,并给出了一个算例。
On the basis of Reynolds equation, the chief mechanism of forming lubricating film was discussed. The structural flaw of the main mating surfaces of tripod sliding universal joints was analyzed and then an anti--wear structure was presented. In light of the force analysis of the main mating surfaces, a simplified geometrical model which would be used in numerical analysis was obtained by using the infinite length assumption. Finally, the governing equations were listed under Newtonian flow model and isothermal conditions and a numerical solution was gained as an example.
