摘要
Abstract
The bearing is considered as the important heat source, It has great influence on the temperature rise during working . In this paper, the transient and steady temperature fields of the high-speed centripetal thrust ball bearing are analysised based on thermal network analysis & finite volume method. Ultimately, steady-state temperature fields are built. As compared with these two methods, this paper sums up the influence law caused by the speed, load and other factors, in order to select the perfect bearing parameter and provide the theoretical basis of the working reliability.关键词
