摘要

Compared with other gear transmissions travelling along meshing line, the motion of crown gear coupling is much more complex, which makes more difficult for its tooth surface wear simulation. To reduce the computational costs associated with the wear simulation of crown gear coupling with misalignment angle, a quick multi-step discretization and parallelization wear simulation model is proposed. The model combines the finite element method based on self-compiled high-precision finite element mesh, kinematic analysis and Archard's formula to predict the tooth surface wear. The characteristics of the relative sliding distance are also discussed, while the effects of the misalignment angle and load torque on the wear depth are investigated. The numerical results show that the maximum relative sliding distance increases with an increase in the misalignment angle, and the relative sliding distance between the teeth near the pure tilted area is larger than that near the pure pivoted area. In addition, when crown gear coupling is aligned, the tooth surface doesn't produce wear, while the tooth surface wear pattern is symmetrical about the middle of the tooth width.
