A theoretical investigation of the effect of inlet pocket size on the performance of hole entry hybrid journal bearings employing capillary restrictors

Abstract A theoretical analysis of hole entry hybrid bearings employing capillary restrictors is presented. The Reynolds equation was solved using finite difference techniques, replacing the negative pressure by P = 0 for the cavitation region. Results are presented for bearings with various pocket sizes at the outlet from the restrictors into the bearing. The results show that the load capacity of this type of bearing is greatly affected by the pocket size at zero speed and at high speed.
