THEORETICAL INVESTIGATION OF GAS INERTIA EFFECTS ON PARAMETERS OF A BEARING WITH CURVILINEAR SURFACES

摘要

Based on a first-order perturbation solution in a modified Reynolds number an analysis is presented to determine the effect of the inertial forces of an isothermal gas lubricant film on pressure distribution and other parameters of a bearing with curvilinear surfaces. The corrections to the pressure distribution are found to be small, but noticeable. It is also found that these corrections in the case of only rotational inertia forces are significant. Numerical results for thrust bearings with a constant film thickness are given in graphical form.
