小型航空发动机联轴器设计及应用

Design and Application of Small Aero Engine Coupling

发动机联轴器对主动轴和从动轴同轴度、重量以及换向和变速时要求传动轴不能受到冲击力等方面有着更高的要求。为进一步满足小型航空发动机减重、简洁、可靠、经济的发展要求,提供了一种小型航空发动机联轴器设计方案并应用。有效的解决了主动轴和从动轴同轴度、机构重量和在换向与变速时传动轴不能受到冲击力的要求,结构简单,消除了换向间隙,提高联轴器的使用寿命和可靠性,并降低了制造成本。

The engine coupling has higher requirements on coaxiality,weight of driving shaft and driven shaft,as well as the requirement that the transmission shaft should not be impacted when reversing and changing speed.In order to meet the development requirements of small aero-engine such as weight reduction,simplicity,reliability and economy,a design scheme of coupling for small aero-engine is provided and applied.It effectively solves the requirements of coaxiality of driving shaft and driven shaft,weight of mechanism and transmission shaft can not be impacted when reversing and changing speed.The structure is simple,eliminates the reversing clearance,improves the service life and reliability of coupling,and reduces the manufacturing cost.
