Abstract
Recent advancements in lubrication and cooling strategies have shown potential for improving the performance of rolling-element bearings. However, a lack of a level playing field for comparing different strategies exists. In this study, a multi-bearing system modeling framework to simulate various cooling and lubrication strategies for rolling-element bearings is developed. The framework facilitates the evaluation of novel cooling and lubrication concepts, in conjunction with both passive and active control strategies. Analyses performed on a multi-bearing system model show that implementing smarter lubrication and cooling strategies in rotary machines can reduce friction losses by 14.8% under a dynamic load. The results offer valuable insights for designing and optimizing machinery, paving the way for energy-efficient and durable systems in various industrial applications.
