Abstract
This paper is concerned with the improvement of the load capacity of the hydrostatic journal bearing. The hydrostatic journal bearing with a plane slider added in the recess as a pad is proposed. An analytical approximate solution of the Reynolds equation applied to the slider is presented. Using this solution, the load capacity and the attitude angle of the self-acting bearing constructed by four plane slider and the present hybrid type bearing are calculated, and the following results can be obtained. (1) The plane slider added in the recess is effective to the improvement of the load capacity of the hydrostatic journal bearing and this effect is remarkable in the region of large eccentricity ratio. (2) The attitude angle of the hybrid bearing is smaller than the hydrostatic journal bearing. (3) The proper values of the clearance ratio of the slider to the maximum load capacity of the hybrid bearing are from 1.5 to 1.8. (4) The larger the aspect ratio of the slider becomes, the larger the load capacity becomes.
