近年来,交通工具都在向高速、大负荷发展,机械传动则向液压结构发展,因而对橡胶密封件的结构及性能的要求不断提高,为了适应机械工业迅速发展的形势,在国际上对流体密封的基本性能研究作了很多工作,对橡胶密封中的O 形圈、Y 形皮碗和旋转油封等的密封机理及结构设计都取得了较大的进展,对提高橡胶密封零件的质量起了很大作用。在国内我们对这些问题却注意得很少。通过几年的研制实践,我们深感有必要探索
In recent years, the transport are in the high-speed, heavy load development, mechanical transmission to the hydraulic structure development, and thus the structure and performance of the rubber seals continue to improve, in order to adapt to the rapid development of the machinery industry situation in the international fluid Sealing the basic performance of the work done a lot of work on the rubber seal in the O-ring, Y-shaped bowl and rotary seal and other seal mechanism and structural design have made great progress in improving the quality of rubber seal parts played Great effect. At home, we pay very little attention to these problems. After several years of research and development practice, we deeply felt the need to explore
