| 中文摘要: |
| 对汽车发动机耐高温带底盘多唇口气门阀杆氟橡胶（FKM）油封的结构、胶料配方、模具设计和生产工艺进行研究。油封的弹簧直接压在底盘上，使用过程中不会发生脱落，密封效果好；油封唇口与阀杆的接触应力最大点靠近油侧或在空气侧与油侧的中部。油封胶料主体材料采用几种牌号的FKM并用，胶料在开炼机上混炼，配合剂先混合再加入胶料中。油封采用连续注压或连续注射硫化成型工艺，二段硫化在恒温烘箱中进行，产品性能达到国外同类产品水平。 |
| 英文摘要: |
| The structure，compound formulation，mold design and production process of fluorine rubber（FKM） oil seal for multi-lip valve shaft of automotive engine with high temperature resistance were studied.The spring for seal was directly mounted on the chassis to avoid seal fall-off and ensured good sealing performance.The maximum contact stress between the seal and shaft was located near oil side or in the middle between the air side and oil side.The main material of the oil seal compound was blend of several different grades of FKM.The compound was mixed on open mill and the additives were mixed first and then added to the compound.The seal was formed using a continuous transfer or injection molding process and post-cured in oven.The performance of the product reached the similar level of imported products. |
