Mesh relationship modeling and dynamic characteristic analysis of external spur gears with gear wear

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 1,   Pages 9-9 doi: 10.1007/s11465-021-0665-z

Abstract: Gear wear is one of the most common gear failures, which changes the mesh relationship of normal gearA new mesh relationship caused by gear wear affects meshing excitations, such as mesh stiffness and transmissionthe influence of gear wear on mesh stiffness and unloaded static transmission error (USTE).Based on the mesh stiffness and USTE considering gear wear, a gear dynamic model is established, andComparison with the experimental results verifies the proposed dynamic model based on the new mesh relationship
