Short summary

This study constructed a mixed elastohydrodynamic lubrication (EHL) model based on the meshing characteristics of helical gears, studied the lubrication characteristics between the meshing tooth surfaces and the temperature change due to asperity contact and oil film shear, and introduced them into the improved Archard wear model to construct the surface wear calculation model. The cumulative distribution law of tooth surface wear and the influence of different factors on the tooth surface wear depth were explored.
