ON THE HYBRID GAS LUBRICATED JOURNAL BEARING

Abstract

The load carrying capacity of an external pressurized gas journal bearing is analyzed including the hydrodynamic effect caused by the rotational speed of the journal. The analysis is an approximate first order perturbation solution, i.e. it assumes small bearing eccentricity ratio. Furthermore, it is assumed that the gas feeding takes place through orifices in the centerplane of the bearing and that the number of feeding oles is sufficiently large to be considered a line source. Results are given for the load carrying capacity and for the attitude angle. In addition an investigation is made of the validity of the approximation used in arriving at the solution.
