Dr.-Ing. Dieter Mevissen is Chief Engineer in the gear department at the Laboratory for Machine Tools and Production Engineering (WZL) of RWTH Aachen University since November 2021. He graduated from RWTH Aachen University with a master´s degree in mechanical engineering. His Ph.D. thesis focused on the prediction of geometric surface changes in rolling-sliding contacts.
This study investigates how manufacturing-related geometry deviations in the tooth root area affect gear bending strength calculations, demonstrating that accounting for measured tooth contours rather than nominal geometries is essential for accurate material comparisons in fatigue testing.
In the present paper, a spline-joint design and the extension of a back-to-back test rig were presented, which enable the testing of crowned spline-joints under high rotational speed, medium torque, high test temperature, and angular misalignments.
