Abstract
Many Factors affect the oil-air lubrication of sliding bearing such as oil supply, air pressure, load, bearing structure and so on. In order to study the effects of bearing structure on oil-air lubrication in sliding bearing, the oil-air lubrication and oil lubrication experiments of grooved sliding bearing have been done by using friction-abrasion testing machine. By means of measuring the temperature rise and the friction coefficient of grooved sliding bearing on oil-air lubrication and oil lubrication with different level of load at the same rotating speed, the results obtained show that the friction coefficient of oil-air lubrication with oil supply 30ml/h, air pressure 0.25MPa is almost the same as oil lubrication with oil supply 1.4L/h. The oil-air lubrication temperature rise is much lower than the oil lubrication in grooved sliding bearing with the same experimental conditions.
