• It is useful and interesting to clarify the behavior of grease lubrication which is available on rolling bearings. To discuss such a problem, a nonlinear integral equation coupling the hydrodynamic equation of a Bingham solid and the elasticity equation of gearing materials is derived in this paper. Solving the equation numerically, the effect of core formation in a Bingham flow on the elastohydrodynamic lubrication between two cylinders becomes clear, and the process of core formation constitute an important part of the elastohydrodynamic problem. The measurements of film profiles also are carried out to compare with the analytical results.
