摘　　要：为了解决转叶式液压舵机存在的泄漏量过大、密封可靠性较差、密封件更换困难等问题,对其结构进行优化设计,对关键零部件进行有限元分析,提出一种新型组合密封。分析新型密封的机理,实例计算表明,该组合密封的静密封泄漏量和动密封泄漏量极小,有利于舵系统正常工作。To solve problems of large leakage, bad reliability of sealing and difficult to replace the sealing elements in the old seal in rotary vane steering gear （RVSG）, its structure was optimization designed. FE analysis was carried out for the key parts to design a new type of composite sealing. The sealing mechanism was studied. A numerical example showed that the static and EHL leakage of the new type of sealing were very low, and it is helpful to the operation of the steering system.
