Abstract
In this paper, based on the Archard wear theory, numerical simulation method and Hertz contact theory, the numerical simulation model of gear rack wear is established under the influence factor of load and hardness for the wear condition of large modulus gear rack. The simulation calculation of its wear process and wear life is realized through the Matlab software. Results show: Along the tooth profile, wear rate of tooth root is greater than the crown. Maximum wear position is decided by comprehensive influence of contact stress and slip distance. The analysis calculation of large module gear rack’s wear process and life can be solved through the method of combining experiment and numerical simulation for good engineering application.
