    Abstract
  • Angular contact ball bearing was taken as investigation object and FLUENT fluid calculation software was used to establish a simulation model of gas-liquid two-phase flow between bearing rings, so as to analyze the atomization of injected lubricating oil liquid under the action of high-speed airflow between rings. The change of oil particle diameter was discussed under the conditions of different rotating speeds and different injection angles at the same time. And the change trend of Sauter mean diameter (SMD) at different times was also discussed. Results showed that with the penetration of lubricating oil, the proportion of oil with large particle size in the cavity decreased gradually, while the proportion of oil with small particle size increased. With the increase of the rotating speed, the amount of oil entering the cavity would also decrease. Influenced by the air vortex between the rings, the oil droplets would disintegrate rapidly, which would intensify the atomization and reduce the particle diameter, thus reducing SMD and affecting the bearing lubrication. Under the condition of different injection angles, the proportion of large particle size in the bearing cavity with the injection angle of 15° was relatively large.
