Wear resistance of gear teeth in the presence of slippage between gear teeth and during rolling

Abstract

This article gives a brief overview of the fracture of contacting parts under the influence of circumferential force in meshing accompanied by rolling and slipping during plastic deformation.

Hardening of gear teeth depending on the concentration of abrasive particles in the transmission oil

“…In the process of operation of tractors in field conditions it is established that in oil of transmission units at their replacement are accumulated solid mechanical impurities consisting of abrasive particles of soil origin and wear products in approximately equal proportions up to 1.3% by mass [1]. In order to ensure the specified service life of gears in terms of wear of gear teeth in one period of oil replacement in the units should not exceed 0.25% (by mass) [2].…”
