In gear drives, what is the purpose of lubrication between gear teeth?

Explanation:
Lubrication between gear teeth forms a thin film that keeps the teeth from rubbing directly together. This film lowers the friction between surfaces, which reduces wear and the amount of heat generated during meshing. With less wear and heat, gears last longer and run more efficiently. Lubrication doesn’t stop gears from meshing, and it typically helps dampen noise rather than increase it.
