Abstract :
[en] This report presents a program for the complete design of a deep groove ball bearing which is submitted to a plane sollicitation. This programs includes a catalogue consultation and the assessment of the tolerances of both races. For these, the computation is based on the exact nonlinear formulation of the problem, and not on approximate values of the catalogues. In particular, it allows to find the infuence of the clearance on the stiffness of the bearing. The bending moment is taken in account. In order to solve the nonlinear equations of the theory, a Newton-Raphson procedure is introduced. In this problem, a proper choice of the starting point is of paramount importance, as the reference position is stiffness-free. This problem is dicussed in detail. The second part of this report presents the ROULBI program and comments its different steps.
