Simulation Research on Tooth Root Dynamic Stress of Marine Helical Gear Meshing Impact
Finite element model of helical gear meshing of large burden marine is established based on explicit dynamics finite element method,dynamics stress variation of helical gear tooth is simulated under multiple working conditions,research is focused on the impact of changes in working conditions on the dynamic stress of the tooth root.The results show that helical gear pair speed and center distance error have great impact on dynamic stress of tooth root,the tooth root dynamic stress in the left of the driving gear load surface is greater than that in the right surface in the transmission process of marine helical gear,the tooth root dynamic stress of non-load surface is higher than that in load surface.The results provide reference for dynamic performance optimization of marine gears.
