Abstract

This paper examines vibration behavior of ball bearings dispersed by solid as a function of contamination of lubricant. Experimental tests were performed using SKF 6004 deep groove ball bearing, dispersed with different contaminants particles. Silica sandwith different particle sizes, copper (Cu micro particles), poly methyl methacrylate (PMMA), low-density polyethylene (LDPE), and polyamide (PA), all at five concentration levels were used to disperse the lubricant. The contaminants concentration as well as the carbon nanotubes (CNTs) concentration is varied as 1, 2, 3, 4, and 5 wt. %. It was found that as the contaminants particles size and concentration increased, the corresponding acceleration values also increased up to certain limit. Furthermore, the vibration amplitudes decrease due to the increase of the copper concentration. The vibration amplitude was improved due to increase of concentration of carbon nanotubes CNTs.
