Estimation of the size of abrasive particles involved in the wear process of gear teeth

Abstract

The article deals with the method of calculating the average size of abrasive particles involved in the wear process of gear teeth working in the oil of closed machine units. Analytical dependences are proposed that allow for calculating the coefficient of friction between the abrasive particle and the gear tooth surface, the largest and smallest sizes of abrasive particles, the thickness of the oil film between the gear teeth, taking into account the elastic deformation of the contact surfaces.
