PURPOSE:To enable to make use of the central part of a rotational disk by supplying high pressure oil to the sliding face of a bearing shoe. CONSTITUTION:Several pressure oil pockets 4b are provided on a sliding face 7 of a bearing shoe 1 around the center to be supplied with high pressure oil uniformly distributed by a discharge control valve 9. This construction approximately equalizes the discharge to the peripheral side from each oil pressure pocket 4b and the thickness of oil film on the sliding face 7, and permits to prevent the lowering of capacity caused by uneven thickness of the oil film even if it is adapted to a large-sized bearing. |
