Meshing Performance Analysis of a Topologically Modified and Formed Internal Helical Gear Pair

Machines, Journal Year: 2025, Volume and Issue: 13(5), P. 340 - 340

Internal helical gear pairs are sensitive to manufacturing and assembly errors, loading deformation, which can result in vibration noise. Three-dimensional topological modification of tooth surfaces is available reduce this sensitivity. A 3D method proposed by means an internal form grinding method. The modified surface model was constructed using spatial meshing theory matrix transformations. Loaded contact analysis (LTCA) established investigate the effect law parameters on performance. Simulation results indicated that area appeared at middle under design conditions, with little edge existing. Transmission error decreased up 28.4% compared without modification. dynamic performance pair enhanced significantly. transmission experiment conducted verify effectiveness validity simulation results.
