对现代汽车部件和总成的要求是等强度且能无故障地工作,油封对此影响甚大。众所周知,零件的潜在可靠性是在设计,研究和指标调整以及运行检验三个阶段中形成的。控制油封质量的一项最重要任务是确定油封最佳可靠性后备系数,而延长其寿命的途径之一是对橡胶表面进行化学变性处理。用丁腈橡胶制成的具有光滑工作刃口的油封经化学变性处理后,由于减轻了橡胶对轴的摩擦磨损而取得较好的效果。 The requirements for modern automotive components and assemblies are equal strength and trouble-free work, and oil seals have a huge impact. As we all know, the potential reliability of parts is formed in three stages of design, research and index adjustment and operation test. One of the most important tasks in controlling the quality of an oil seal is to determine the best reliability back-up factor for the oil seal, and one of the ways to extend its life is to chemically modify the rubber surface. Seals made of nitrile rubber with a smooth working edge after chemical modification, due to reduce the friction and wear of rubber on the shaft and get better results.
