22FTM22. Test Rig for Crowned Spline-Joints with Optimized Surface Treatments Under Misaligned Conditions

ABSTRACT

Increasing the load capacity of spline-joints in shaft-gear connections, such as UHBR-aero-engines, leads to a lean and efficient design of the power train components. An approach for this is to apply optimized surface treatments, such as coatings and laser structuring, which can reduce the risk of upcoming wear and fatigue phenomena. To assess the potential of these surface treatments for spline-joints, tests under real working conditions need to be carried out. As the application is an UHBR-aero-engine gas turbine, component tests are not applicable in the application for economic reasons. Hence, a design for a test spline connection, as well as a test rig for investigations of the wear and fatigue behaviour of surface treated spline-joints are presented.
