摘要

The purpose of the paper is to numerically investigate the acoustic noise characteristics of cylindrical roller bearings. For the sake of simplifying of the analysis, it was assumed that the cylindrical roller bearings are infinitely long, and that there is no outside force acting on the bearings. Furthermore, the effects of the following on the noise of the bearing were also examined: the radial clearance of the bearing, the viscosity of the lubricant, and the number of rollers. The results of the study show that the fundamental frequency of the noise components of the cylindrical roller bearing corresponds to the multiplication of the number of rollers and the whirling frequency of the roller center. The acoustical frequency spectra of the cylindrical roller bearing are pure tone spectra, containing the fundamental frequency of the roller bearing and its super-harmonics. The factors that decrease the sound pressure level of a cylindrical roller bearing include: low lubricant viscosity, high radial clearance and a reduced number of rollers. The results and discussions of the present paper could aid in the design of low-noise cylindrical roller bearings.
