ADORE Validation of Bearing Heat Generation for a 133-mm Bore Angular Contact Ball Bearing

摘要

(1) At light loads: Bearing power loss due to lubricant churning and drag effects. (2) At high loads: Traction contributions match churning and drag. (3) ADORE predicts heat generation well at light to moderate loads. (4) ADORE's Newtonian traction model overpredicts power loss at high loads w.r.t. experimental data. (5) Agreement between experiment and ADORE predictions for load dependent power loss. (6) Quasi-static bearing models do not account for load dependence. (7) At conditions in which most heat generation is thru lubricant churning and drag, both dynamic and quasi-static prediction tools agree.
