在旋转轴、旋转孔、往复运动轴或往复运动球面的密封结构中,采用橡胶油封作为主要密封元件的历史并不很长。二十多年来国内外密封专业对密封机理的探讨不断深入,适应不同工作条件的新结构橡胶油封不断出现,橡胶油封也从四十年代的牛皮油封代用品发展成为一种精密的、针对性强和使用效能好的密封件。由于机械工业迅速发展,特别是高线速度、高温、深冷等苛刻的工况和对使用寿命的严格要求,促使橡胶油封制
In the rotating shaft, rotating hole, reciprocating shaft or reciprocating spherical sealing structure, the use of rubber seals as the main sealing element of the history is not very long. Over the past 20 years, the sealing professionals at home and abroad have been exploring the sealing mechanism continuously. New rubber seals are constantly appearing to adapt to different working conditions. The rubber seals have also evolved from the substitute of leather oil seals in the 1940’s into a sophisticated and targeted Strong and efficient use of the seal. Due to the rapid development of the machinery industry, especially the harsh conditions such as high linear velocity, high temperature and cryogenic conditions and the strict requirements on the service life, the rubber oil is sealed
