Abstract
To explore the correlation between vibration and power consumption of angular contact ball bearings, the evaluation of power consumption was merged into the original nonlinear dynamic model of ball bearings and this model was validated by the experimental method. On this basis, a comprehensive analysis of vibration and power consumption of ball bearings was conducted, then, the variations in the power consumption and vibration at different numbers of balls and groove curvature radii were studied, again, their optimal combinations were determined to attain the acceptable power consumption, dynamic stability and vibration in the bearing system. The corresponding results illustrate that reducing the maximum number of balls by one or two can obtain the good dynamic performance of friction consumption, dynamic stability and vibration of ball bearings, besides, the combination of inner and outer groove curvature radii should both strengthen contact loads and effectively guide the motion of the ball to get the favorable comprehensive performances.
