Load Distribution of Rolling Bearing for Steel Shapes Universal Roll Mill

At the stage of the start and end for rolling H-beam by universal rolling method, there exists biting and tailing-out phenomenon in the stage, the rolling bodies endures repeating impact loading for the bearings. In order to ensure the working safety and reliability for universal roll mill, according to Hertz contact theory, small deformation superposition principle, and etc. Setting bearing clearance is 0.1 mm, maximum rolling force is 8000 KN for the level rollers, without consideration of influence of friction, and researches and deduces the mathematic models of force calculation for rolling bodies. The results shows that the thickness of the rolling bearing had very little effect on load distribution of rolling body, the calculated results coincide better with finite element results, and the achievements can supply a reference of the production of hot rolling for H-beam.
