Oil lubrication technology has been widely used as a new and efficient means of lubrication.Comparison test method to verify the feasibility of oil and gas lubrication technology used in which plain bearings.Sliding friction pairs using the traditional pure oil lubrication and oil lubrication two kinds of lubricating the way through trial compared the specimen temperature rise,friction torque and other parameters changes both lubrication mode.After the experiment showed that compared with traditional lubrication oil lubrication lubrication of plain bearings is better.
