Abstract:
This study is dedicated to an important contact problem, which appears in the bearings with a diametrical game, when the shaft is restored by its coverage by a composite polymer layer. By using the method of incompressible influence elements there were constructed Green’s matrices (GM) for displacements within a polymer composite circular layer with mixed boundary conditions. These GM were applied to solve the static contact problem, when the polymer composite circular layer contacts with a metallic piece. Thus, there were obtained two systems of equations, which permit to determine load capacity and the coverage angle of the compression zone of the polymer composite layer and a diametrical game of bearing. These results can be applied to determine parameters of restored bearings of an agricultural machine mentioned above.
