| Sumario: | This paper describes a nonlinear vibration analysis of angular contact ball bearing of a rigid rotor considering waviness of ball and races. Five degrees of freedom dynamic model of the rotor-bearing system has been analyzed using Runge?Kutta algorithm and MATLAB software. Comparisons of peak amplitudes of the vibrations due to different defects are presented for the lubricated condition of the bearing. Based on the computed results, it has been observed that in the presence of lubricant film at the contacts of balls and races, vibrations reduce significantly. However, large amplitudes of waviness and increase in spindle mass enhance the vibrations. |
