Power Losses of Oil-Jet Lubricated Ball Bearings With Limited Applied Load: Part 2 - Experiments and Model Validation
Résumé
This paper presents an experimental study on load independent power losses in oil jet lubricated deep groove ball bearings. These experiments were performed under different operating conditions. Rotational speed, lubricant temperature, oil flow rate and rolling element bearings dimensions were varied to quantify their influence on power losses. A load-independent power losses model for rolling element bearings has been proposed in a companion paper (Darul et al., 2023, "Power Losses of Oil-Jet Ball Bearings with Limited Applied Load: Part 1-Theoretical Analysis") and was used here to simulate experiments. Model results and measurements are compared. A good agreement is found on the power losses in low loaded deep groove ball bearings.
