摘要
分析海水润滑轴承的主要磨损形式,建立海水润滑赛龙陶瓷轴承的弹流润滑模型,通过数值计算发现在赛龙陶瓷/钢摩擦副间可以形成海水弹流润滑膜,轴承间水膜厚度分布有明显颈缩现象,但压力分布图中第二压力峰不明显;随着转速的增加,海水润滑膜膜厚及最小膜厚都变薄;相同条件下,赛龙陶瓷轴承用海水润滑比用纯水和油润滑时更不容易形成弹流润滑薄膜。
The main wear forms of seawater lubricated bearing were analyzed. The elastohydrodynamic lubrication （EHL） model of Sialon ceramic bearing was established. The numerical results show that the seawater EHL film can be formed between SiMon ceramic bearing and steel spindle. The necking phenomenon is very obvious in the film thickness profile illustration. But the second pressure peak is not obvious in the pressure distribution illustration. As the speed increases, seawater film thickness and minimum film thickness become thinner. The formation of EHL film of Sialon ceramic bearing with seawater lubrication is more difficult than with pure water or oil lubrication under the same conditions.
