STUDY OF THE VIBRATION CHARACTERISTICS OF BEARINGS.
Abstract
The narrow band vibration spectrum of NJ256K cylindrical roller bearing was studied. Peaks induced by roller waviness were identified experimentally. The effect of radial load and rotational speed on the vibration level of the NJ256 cylindrical roller bearings was studied. The vibration characteristics of a 23240 spheri cal roller bearing were studied and the results were compared with those of the 23256 spherical roller bearings tested previously. Twenty-three hundred, two hundred and fourty spherical roller bearings with improved bearing components were tested. The effect of waviness of each bearing part on the vibration level of the assembled bearing was analyzed and the relative improve ments of each part are discussed with respect to the reduction achieved in the vibration level.
