Abstract
Because of the influence of rotary kiln supporting wheel's deflection on the contact area's contact stress, according to Hertz contact theory, the relative among deflection angle, the maximum contact stress and maximum contact stress ratio when supporting wheel is under parallel and deflective are derived. Furthermore, with the finite element method, the contact problems when supporting wheel is under parallel and the maximum deflection angle state are solved. Distribution of supporting parts'maximum contact stress and the equivalent stress and strain are obtained, and the dangerous and damageable place is learned. These analysis conclusions can provide effective theoretic guidance for rotary kiln axial adjusting and controlling.
