Parametric Design and Finite Element Analysis of Involute Helical Gears

摘要

The establishing for involute helical cylindrical gear and involute helical bevel gear were completed based on Pro/E. The simulation for assembly and operation was also accomplished for them. The modal analysis, static analysis and the dynamic contact transient analysis for the involute helical gears were finished by using ANSYS. The statics analysis results showed that on the premise of the same load the equivalent stress of involute spiral bevel gear and other principal stress were larger than involute helical cylindrical gear. The dynamic contact analysis showed that the involute helical gear tooth surface contact stress in the meshing process gradually became larger and then gradually became smaller. The contact stress distribution was mainly concentrated in the ends of the gear, so we should pay attention in the design and use.
