Abstract
Bearings are one of the most widely used mechanical devices that transmit load with limited friction. The bearing operation leads to heat generation at the contact regions and this can be moderate in case of pure rolling and quite high in case of slip. This increase in temperature leads to lower viscosity of the lubricant, which in turn results in a lower lubrication efficiency. This can lead to metal-metal contact which can results in increased risk of friction and wear. Excessive flow of lubricant near the contact region is also not favorable as the lubricant that is not in the contact region ends up generating additional drag forces while not contributing to the lubrication to the bearing. The goal is therefore to obtain an optimal lubrication strategy which lubricates and cools the bearing with limited loss in efficiency due to the viscous drag effects. In this paper a 3D CFD model for single-phase flow and (conjugate) heat transfer in a tapered roller bearing submerged in an oil bath is developed. The flows inside such components are very complex and the heat generation at the contacts adds additional complexity to the problem. The large dimensional disparity between the different components and high rotational speeds make the problem computationally very expensive. The lubricant flow behavior is presented in the form of velocity flow field and streamlines while, the thermal aspects of the problem are presented in terms of cross-sectional temperatures and heat fluxes on the bearing component surfaces. These results give a glimpse into the complex flow and heat transfer phenomena that occurs inside a bearing system.
