The Research on Oil-Air Lubrication and Oil Lubrication in the Sliding Bearing

Abstract:

In order to study the effect of oil-air lubrication on traditional sliding bearing, the experiments oil-air lubrication and oil lubrication have been done by using friction-abrasion testing machine. By means of measuring friction moment, the temperature rise of two different lubrication systems in the same conditions and studying the friction moment and the temperature rise of oil-air lubrication and oil lubrication with different load at the same rotating speed level, the results obtained show that when rotating speed and oil supply is at 210rpm and 1.4L/h level, the friction moment of traditional sliding bearing with oil lubrication increases significantly after the load 900N, and when rotating speed, oil supply and air pressure is at 210rpm , 30ml/h and 0.25MPa level, the friction moment of traditional sliding bearing with oil-air lubrication increases significantly after the load 1500N. The friction moment of oil-air lubrication and oil lubrication is almost the same before the load 900N, and after the load 900N, the friction moment of oil-air lubrication is much lower than the oil lubrication. The oil-air lubrication temperature rise is much lower than the oil lubrication in traditional sliding bearing with the same experimental conditions.
