THE EFFECT OF MISALIGNMENT ON POWER LOSS IN BALL BEARINGS

A vectorial method has been developed to solve the quasi-static equilibrium in angular contact ball bearings. In the quai-static model the effects induced by the centrifugal forces, gyroscopic moments and misalignments between bearing's rings were considered. The lubricant parameters, traction forces and fluid drag action on balls and raceways were further included in a quasi-dynamic model, An experimental study has been further carried out to validate the quasi-dynamic model when a certain degree of misalignment exists between the inner and outer rings of the bearing. Both numerical simulation and experimental measurements emphasized the major contribution of the rings misalignment upon the bearing power loss.
