Gear surface wear is an unavoidable tooth profile deviation and can influence gear load distribution and transmission error. Because of that, it is necessary to study the interaction between them and wear. For that purpose, a modified wear prediction model has been established by combining the potential energy method, and an improved load distribution model considering the effect of corner contact. The load share ratio (LSR) obtained from the improved model is verified by the finite element method (FEM). And relative to the FEM, the proposed model is much more efficient. Besides, the influences of wear accumulation process and corner contact on loaded static transmission error (LSTE) and load distribution are discussed. The results show that considering the effect of corner contact is necessary and can improve the accuracy of the wear prediction. And, it can be observed that there is a significant time-varying characteristic on LSTE, LSR of worn gear, as well as a correlation between them. Furthermore, the influence of gear modulus and gear ratio is discussed as well and it is found that both can effectively reduce the wear depth and significantly influence the condition of corner contact.

齿轮表面磨损是不可避免的齿形偏差，会影响齿轮负载分配和传动误差。因此，有必要研究它们与磨损之间的相互作用。为此，通过结合势能方法和考虑角接触影响的改进的负荷分配模型，建立了改进的磨损预测模型。通过有限元方法（FEM）验证了从改进模型获得的负载分担比（LSR）。相对于FEM，所提出的模型效率更高。此外，还讨论了磨损累积过程和角接触对载荷静传递误差（LSTE）和载荷分布的影响。结果表明，考虑角接触的影响是必要的，可以提高磨损预测的准确性。并且，可以观察到，磨损齿轮的LSTE，LSR以及它们之间的相关性具有显着的时变特性。此外，还讨论了齿轮模数和齿轮比的影响，发现两者都可以有效地减小磨损深度并显着影响角接触条件。
