Research on gear mesh misalignments under the system deformation

摘要

The gear transmission is a complex elastic system. The system deformation under the load will make the position of mating gear deviating from the ideal position. The deformation varies with different gear shifts and load that will cause the different type of gear mesh misalignments. Therefore, the researches on the gear mesh misalignment should consider the effect of deformation of gear system under different working conditions. The paper established an elastic model of commercial vehicle transmission system. The gear mesh misalignments under different shifts and different load are obtained considering the integrated system deformation. The variation values of gear mesh misalignments are analyzed correspondingly.
