Prediction of heat generation in transmission bearings by application of fem
Apstrakt
Heat generation in bearings is manifested by the power losses of the transmission. Because of the rise in temperature due to heat generation, appearance of dilatation adversely affects the bearings geometrical characteristics. Heat generation has an adverse effect as well on the properties of lubricant, its efficiency of work and rheological characteristics. There are several ways for heat generation within rolling bearing: By friction between the rolling bodies and raceways, due to hydraulic resistance of lubricants, friction between the rolling bodies and cage, friction between the cage and rim of rings and friction between the seals and rings. This paper discusses the first of these five causes, which is considered to be dominant. By application of finite element method, the heat generation between the rolling bodies and raceways was predicted. Paper studies the influence of contact load and angular speed on the heat generation, while taking into the account the thermal properties o...f the bearing components. Based on performed numerical research a new method for prediction of heat generation in transmission bearings was proposed.
