| 中文摘要: |
| 针对机械厂连铸辊设计了一套密封系统，该系统由双层Y形橡胶密封圈（简称Y形圈）构成。通过有限元分析，得到过盈量和油压对Y形圈应力的影响规律，即随着过盈量的增大，Y形圈的最大接触应力先增大后减小，随着油压的增大，Y形圈的最大接触应力逐渐增大；从加压后Y形圈的接触应力变化，可以估计Y形圈老化后断裂失效的区域主要在凹槽部位。以氢化丁腈橡胶为主体材料和采用过氧化物硫化体系制得的Y形圈的密封性能良好。。 |
| 英文摘要: |
| A sealing system was designed for the continuous casting roll in machinery plant，which consisted of double-layer Y-shaped rubber seal rings（referred to as Y-shaped rings）.Through finite element analysis，the influence low of the interference fit and oil pressure on the stress of the Y-shaped ring was obtained.That is，as the interference fit increased，the maximum contact stress of the Y-shaped ring increased at first and then decreased，and as the oil pressure increased，the maximum contact stress of the Y-shaped ring gradually increased.By analyzing the change in contact stress of the Y-shaped ring under pressure，it could be estimated that the fracture failure area of the Y-shaped ring after aging was mainly in the groove area.The sealing performance of the Y-shaped ring using hydrogenated nitrile rubber（HNBR） as the main material and adopting a peroxide vulcanization system was excellent. |
