The Research Of Block Lubrication And Simulation Of Rolling-sliding Compound Bearing

Rolling-sliding compound bearing is a kind of setting rolling bearing and slidingbearing advantages in one of the new type of bearing.In this paper,This paper will be torolling-sliding compound bearing for dynamics simulation focusing on the stress state ofroller and the slide block and the speed of the slide block and inner ring. From thesimulation result which we can reach the following conclusion: The rolling-slidingcompound bearing’s main stressed cell is slide block and roller is mainly used tomaintain a good satiability and operation of high-speed.The rolling-slidingcompound bearing has a good performance on movement.Focus on the mechanism of lubrication of the rolling-sliding compound bearing’sslider in-depth research and verify its ability to form a film through the derivation ofmathematical formulas. By using Fluent software to block in the ring on the lubricationbehavior of motion simulation, it is concluded that inside and outside circle pressuredistribution deprogram. From the pressure distribution cloud picture can see thatrolling-sliding compound bearing and sliding bearing of the same lies in their formation inthe positive pressure area also formed the negative pressure area. The difference is slidingbearing of the positive pressure area and negative pressure area are fixed, and roll slidingbearing because of slide block in constant motion its positive pressure area and negativepressure regional variations.
