摘　　要：燃气涡轮发动机“停车抱轴”是这种发动机的一项典型问题,也是在目前对发动机性能越来越高的追求下无法避免的问题。一旦出现抱轴,发动机将无法起动,只能等待转静子恢复间隙,少则一两个小时,多的甚至达到近十个小时。本文通过分析某发动机出现抱轴的现象,验证试验的结果,结合某燃机实际使用情况,对造成转静子抱轴的可能原因进行了分析,并根据实际试验情况提出了解决措施。希望对后续发动机解决同样问题提供一些参考。Gas Turbine Engine rotor and casing rub is a typical shortcoming of that kind of machine,and it is also an unavoidable problem in the current pursuit of higher engine performance.Once shaft jamming occurs,the engine will not be able to start and can only wait for the rotor to recover its clearance,ranging from one or two hours to nearly ten hours.Use the examination and a gas turbine,analyse the reason of rotor and casing rub,then present method.
