On the vibration of ball bearings
WebThe effect of ball size variation in the bearings on the vibration of the shaft is investigated. A computer program was developed to simulate this effect, with the results presented in time and frequency domains. All results show that off-sized balls in the bearing cause vibrations at cage speed and its harmonics, depending on their arrangement ... WebHybrid ceramic ball bearings with silicone nitride balls and steel rings were tested, and the vibration characteristics were compared with those of conventional steel ball bearings. …
