摘要

The herringbone gear transmission system is widely used in the field of high-speed and heavy-load ships. However, the power transmission system will produce excessive vibration due to loaded deformation and errors of tooth, while modification technology is the most effective method to realize vibration reduction. Therefore, the paper proposes quadric polynomial combined 3D modification method of herringbone gear and derives the modified tooth surface equation. The tooth contact analysis model and the coupling multi-clearance nonlinear dynamic model of modified herringbone gear pair are established. A multi-objective optimization design model is established with the minimum error amplitude, load density, meshing impact amplitude and acceleration root mean square(RMS) as the optimization objective, and the optimal modification parameters are obtained by ant lion optimizer(ALO). The influence of different modification ways on contact performance and dynamic characteristics of tooth surface under different working conditions is analyzed, and a power flow closed modified herringbone gear transmission system test bench is built to test the established model and analysis results to verify the effect of 3D modification. The results show that 3D modification is more beneficial to improve contact performance and dynamic characteristics than single tooth profile and axial modification.
