Перспективная методика определения тепловыделения в подшипниках качения и температуры подшипников

Abstract

Currently, methods for determining heat generation in bearings have satisfactory convergence with actual values in a limited range of bearing sizes and operating conditions. These methods do not take into account the temperature of the bearings, which determines the viscosity of the lubricant in the contact areas of the rolling elements and bearing rings. As the bearing temperature increases, the thickness of the lubricating layer in the contact area decreases. Wear and heat generation in the bearing increases. This article presents a promising method for calculating heat generation in rolling bearings, taking into account the relationship between heat generation, lubrication properties, bearing operating mode, its parameters and temperature.
