Short summary
The paper studies the three-dimensional contact finite element model of a double helical gear-shaft-bearing system based on the load-bearing contact analysis of the tooth surface. The results show that the tooth surface bearing contact of the system has the phenomenon of partial load due to the supporting deformation, and the unmodified herringbone gear has obvious contact stress concentration, which can be effectively improved by gear tooth modification.
