Effect of assembly error on the meshing characteristic of spacial heveloid gears

摘要

For the beveloid gears with intersecting axis and crossed axis coexisted in the marine gearbox with small down angle, contact analysis of the meshing gear pair taken the assembly error into consideration is proposed based on the nonlinear finite element analysis software Abaqus. Considering the central distance error, axial position error and the angle error, the FE model of beveloid gear pair with intersecting axis and crossed axis were established, respectively, and the tooth contact stress, the maximum influence factor and transmission error were calculated. The effects of these errors, the central distance error, axial position error and the angle error on the contact characteristic were discussed.
