POWER LOSS COMPUTATION IN ANGULAR CONTACT BALL BEARINGS
Mots-clés :
Ball bearings, Friction, Power loss, Oil lubricationRésumé
The paper presents a method for the computation of the power loss in angular contact ball bearings. Dynamic effects, generated at high-speed, are also included in the model, as centrifugal forces and gyroscopic moments acting on balls, balls and cage interactions, ball and cage drag and churning in the lubricating bath oil.
As concerning the estimated power loss in ball bearings, the model offers outputs in good agreement with the results found in literature.
