THE APPEARANCE OF PITTING WEAR ON GEARS AND SOME OF THE FACTORS THAT INFLUENCE IT

Claudiu Ovidiu POPA, Simion HARAGÂŞ

Abstract


Abstract: This article aims to evoke some aspects of the fatigue cracks that have the consequence of pitting wear appearance on the spur gears. Different factors acting on the already propagated cracks and opened to the surface of the gear tooth will be considered. The result is the appearance of a pit. The stresses field corresponding to the contact between two cylinders that shape the contact between the teeth flanks was presented. A possible way of forming the cracks that start from the surface of the flanks is also presented.

Key words: pitting, fatigue crack, pits, gear, stresses field, rollers, lubricant, voids, inclusions.
