摘　　要：浮动渐开线花键是直升机减速器中典型传动结构。由于浮动花键一般采用齿侧定心,存在内外花键轴线不同心的现象,传扭过程中齿面会出现一定的相对滑移,花键齿面提前发生磨损,从而降低直升机减速器的寿命。以直升机减速器中典型的浮动渐开线花键为研究对象,针对花键的磨损损伤,设计典型直升机减速器浮动花键结构,搭建浮动花键磨损试验台;针对不同材料及硬度下的浮动花键开展了摩擦磨损对比试验,研究不同材料及硬度下浮动花键的抗磨损能力并分析了其磨损机理,为后续直升机减速器中浮动花键抗磨损设计奠定了基础。Floating involute splines are typical transmission structure in helicopter gear boxes.As the floating splines are generally centered on the tooth side,there is a difference between the internal and external spline axis,and the tooth surface has a certain relative slip in the transmission of torque,which makes it easy to wear out the spline tooth surface and reduce the life of the helicopter gearbox.Taking the typical floating involute splines in helicopter reducer as the reserch subject and focusing on the wear damage of the splines,designs a typical helicopter gearbox floating spline structure and sets up a floating spline wear test bench.Wear tests on floating splines with different material and hard ness are carried out,the wear resistance of floating splines with different material and hardness is compared,and its wear mechanism is analyzed,which lays the foundation for follow-up wear designing of floating spline in helicopter reducer.
