我厂汽车用半轴油封,为骨架式橡胶油封,是由专业密封件厂生产的外协件。产品在多年的使用中,终始不能完全达到有关标准要求。为提高油封的密封性和使用寿命,也曾委托有关密封件专业厂进行油封设计,但油封设计的参考资料相同,所设计油封结构尺寸也基本相同。例如油封工作唇口的过盈量的选择,都是根据相同资料选过盈量为(轴径_(-1))~(0.7)。所以此种结构油封的密封性相差不多。
I plant semi-axial seal with a rubber seal for the skeleton, is a professional seal factory production of the Association. Products in use for many years, the end can not fully meet the standards. In order to improve the sealing and service life of the oil seal, the oil seal design has also been commissioned by the professional seal factory. However, the reference materials for the oil seal design are the same, and the oil seal structure dimensions are basically the same. For example, the choice of the amount of interference of oil seal lip work, are based on the same information selected interference (shaft diameter _ (- 1)) ~ (0.7). So the seal of this structure is similar.
