Thrust bearing

The invention relates to a thrust bearing, which is characterized by comprising 6 to 24 thrust bearing pad groups; each thrust bearing pad group comprises thrust bearing pads and a supporting pad; the independent thrust bearing pad groups are evenly distributed on a same ring-shaped plane; a supporting block is arranged between the thrust bearing pads and the supporting pad; the lower-part end surface of the supporting pad is a spherical cambered surface; and the radial central line of each supporting block lags behind the geometric central line of the corresponding thrust bearing pads. The thrust bearing has the advantages that as a plurality of groups of thrust bearing pads and the supporting block of the spherical cambered surface are adopted, the stress surfaces of the thrust bearings are even; stop pins effectively control the radial swinging width of the thrust bearing pads; as the radial central line of the supporting block lags behind the geometric central line of the thrust bearing pads, and due to wedge-shaped lubricating oil inlets, oil films are easily formed on the surface of the thrust bearing pads so as to reduce the temperature of touching surfaces; both the supporting block and the stop pins can prevent the thrust bearing pads and the supporting pad from being deviated; among a plurality of independent thrust bearing pads, individual thrust bearing pad can be replaced separately, and therefore the maintenance cost is reduced.
