doi:10.3901/JME.2022.05.151

Abstract

Abstract: Aiming at the problem that the thermal characteristics of cylindrical roller bearings affect the deformation of the inner and outer rings of the bearing and the mechanism of the bearing contact mechanics is not clear, a dynamic analysis considering the influence of temperature, speed, lubrication and other parameters on the displacement and raceway stress characteristics of the inner and outer rings of cylindrical roller bearings is carried out. First, the thermal-mechanical coupling finite element model of the shaft-cylindrical roller bearing-bearing seat system is established, and the validity of the finite element model is verified by testing the bearing deformation and the rationality of the mesh size. The displacement and raceway stress characteristics of bearing inner and outer rings under different speeds, oil temperature and flow rate are analyzed. The results show that the displacement of the bearing ring gradually increases with the increase in speed; the influence of lubricating oil temperature on the raceway stress depends on the size of the bearing clearance, and the bearing raceway stress is greater under low-temperature lubrication; the displacement of the inner and outer rings of the bearing changes significantly from the starting state to the thermal equilibrium state, and the displacement changes at different ferrule angular positions are different, and the outer ring displacement is greater than the inner ring displacement as a whole.

Key words: cylindrical roller bearing, thermal characteristics, ring deformation, raceway stress
