对于在长期工作周期下密封大型的螺旋桨轴作了研究.在1958年对于海军应用中的特殊要求产生了一种发展的方案,以改变现行的园周形大型轴密封件.本文讨论了研制工作的成果,以及对船尾管密封件和螺旋桨轴密封的其它种类的设计.引证了对于处在特别震动条件下的海军舰只和装有大型螺旋桨轴的快速行进的商船两种条件的应用情况.并与其它型密封如唇型密封和面型密封的工作寿命作了比较,既比较了在震动负荷和苛刻的工作条件下的性能又比较了磨损和泄露速率.
A study was undertaken to seal large propeller shafts over a long period of working life, and a development program was developed for the special requirements of naval applications in 1958 to alter the existing perimeter-shaped large shaft seals.This paper discusses the development work , As well as other types of designs for stern tube seals and propeller shaft seals, citing the application of two conditions for naval vessels in special shock conditions and for fast marching merchant ships with large propeller shafts. Other types of seals, such as lip seals and face seals, have been compared for their working life to both wear and leak rates compared to their performance under shock load and harsh operating conditions.
