The lubrication design of gear is based on the assumption that the lubricant is an ideal Newtonian fluid. In fact, The Ree–Eyring fluid model is more in agreement with the lubricant rheological behaviour under medium or mild duty load. It is necessary for engineering lubrication design to study the non‐Newtonian transient thermal elastohydrodynamic lubrication (EHL) of gear. In the paper, a full numerical solution to the non‐Newtonian transient thermal EHL of gear is obtained by utilising the multi‐grid method, which has strong numerical stability, a quick convergence rate and a high degree of accuracy.
