Abstract. In this paper, the study of Numerical analysis of bearing lubrication flow field is presented. Through the experiment, due to the centrifugal force, the liquid diffusion of a uniform surface. when v=1094mm/s, the whole surface has smaller accumulation of fluid film thickness of thicker body, this condition is not conducive to the ball body heat, proper ball rolling speed can in the fluid diffusion into the surface of the ball. Without contact with the stationary samples, the fluid diffusion area. And when the rolling ball contact with the stationary sample, the liquid will be together, the radius is smaller, the fluid gathered more concentrated, which is not conducive to the rolling lubrication and cooling.
PrefaceRolling bearing is a kind of mechanical component widely used in mechanical transmission. High speed ball bearing under the working state, the rolling, the guide plane of the retainer ring and the contact friction loss and bearing internal flow field of fluid viscous dissipation and other reasons will produce a large amount of heat, if the power loss of poor heat cannot be distributed, it will seriously affect the working performance of the bearing. The paper of Pinel et al [1][2][3] studied the bearing temperature and power loss with the increase of the amount of oil, with increasing the amount of oil bearing, low temperature rise, but at the same time, the greater the friction stir oil, it should choose the proper amount of lubricating oil. Li Bin [4][5][6] has experimentally investigated the characteristics of two phase flow and heat transfer in the bearing cavity by experiments and simulations. As early as the 60s of the last century, the idea of heat transfer was applied to calculate the temperature of rolling bearings by Harris and Burton [7]. In 1980, Kleckner [8] put forward a large-scale analysis software CYBEANO for cylindrical roller bearings.
