现代小型轻系列发动机要求安装在铝箱体中的弹性唇型油封能够在更高的曲轴转速及增高的温度条件下工作,并且应具有抗机油添加剂侵蚀的能力。已证实了在发动机上使用氟橡胶材料代替硅橡胶材料可以改善密封性能。为此,研制了一种用半金属/半橡胶做外圈的强化氟橡胶高性能曲轴油封,它改善了在铝箱体中的安装和固定,其寿命超出了目前一般技术制造的油封。 Modern, Light, Light Series Engine Requirements Flexible lip seals mounted in aluminum cabinets work at higher crankshaft speeds and increased temperatures, and should be resistant to attack by oil additives. It has been confirmed that the use of Viton instead of Silicone rubber on the engine can improve the sealing performance. To this end, developed a semifinished semi-rubber outer ring of enhanced fluorine rubber high-performance crankshaft oil seal, which improves the mounting and fixing in the aluminum box, its life beyond the current technology of oil seals.
