Grease lubricants are widely used in rolling contact applications to reduce friction between two surfaces. Improper lubrication may cause high stress and deformation the bearings lead machine failure The purpose of this study is investigate coefficient produced by newly developed palm oil-based grease characteristics lubricated roller bearings. In work, new greases was evaluated experimentally ...

In order to improve the utilization of materials, improving stamping cage processing methods, the single row tapered roller bearing cage is improved from structural strength, puts forward whole stamping cage a type of structure. Use ANSYS finite element analysis to the different structure and the thickness cage. Get the stress contours of the cage, based on equal strength design principles. Get...

Abstract The lubricating layer located between the rolling bodies plays a crucial role in ensuring service life of bearings. Calculating contact with each other taking into account their compliance and lubrication parameters is complex elastic-hydrodynamic problem, for solution which computer programs are usually used. paper proposes hybrid approach based on separate elastic hydrodynamic proble...
