材料与硬度对浮动花键磨损影响的试验研究
Experimental Study of Material and Hardness Effect on Wear of Floating Splines
摘要
Abstract
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.关键词
