摘要(Abstract):

从解决汽车发动机水封异响入手,分析了异响产生的原因,并通过密封理论和试验验证利用激光加工表面技术改善汽车发动机水封的润滑性能。
One of the most important issues for mechanical seals is how to achieve two contradictory functions: sealing and lubricating performance at the sliding surfaces. Various studies have been presented so far. This paper proposes a surface design concept for achieving low-friction and low-leakage mechanical seals by laser surface texturing. The theoretical and experimental results demonstrated that the low-friction and low-leakage seals were technically feasible. These results also indicated that the seals were operated with hydrodynamic lubrication and had an effective pumping effect.
