A non-Newtonian numerical solution system for the transient thermo-elastohydrodynamic lubrication (TEHL) model has been proposed for a helical gear pair with the finite line contact theory. This model is used to comprehensively show the transient effect. temperature effect. operating condition and the non-Newtonian behaviors on the lubricating performance. https://normakamalies.shop/product-category/earrings/
