Influence of elastic modulus of bearing materials on mixed elastohydrodynamic lubrication performance of journal bearings and experimental investigation

Abstract

In order to improve the lubrication performance of marine bearings under low speed and heavy load conditions, a mixed elastohydrodynamic lubrication model considering elastic deformation, turbulence effect, rough surface contact, and fluid lubrication is established. A load control technology combining electromagnetic and hydraulic pressure is designed, and an experimental investigation of the water-lubricated bearings is carried out. Then the influence of elastic modulus of bearing material on lubrication performance is studied. The results show that the vertical stiffness of the rubber bearing is close to a fixed value under low speed and heavy load conditions; The selection of organic polymer materials can effectively reduce the rough surface contact force, and avoid the friction and wear of the bearing.
