| 摘 要： | 利用考虑惯性力的Reynolds方程,对乳化液润滑条件下复合塑料轴承的弹流润滑问题进行了数值模拟,讨论了载荷、转速和轴承轴径大小对乳化液膜压力和膜厚的影响.结果表明:在乳化液润滑条件下,惯性力对乳化液膜压力的影响很小,而对乳化液膜厚度的影响较大;随着载荷的增大,压力峰值有明显增大,而在入口区压力随载荷增大而减小,膜厚以及最小膜厚随载荷减小而明显增大;转速和轴承轴径大小对乳化液膜压力的影响不明显,而膜厚以及最小膜厚随转速增大而明显增大,随轴承轴径的增大而减小.

| Abstract: | Based on the Reynolds equation considering the inertia force,the numerical simulation of elastohydrodynamic lubrication(EHL) for emulsion-lubricated composite plastic bearing was made,the effects of the load,the speed and the shaft diameter on the pressure and the film thickness were discussed.The results show that the inertia force has little effect on the pressure and great effect on the thickness under emulsion-lubricated condition.The pressure peak is increased greatly and the pressure is decreased at i... |
