Thrust bearing for centrifugal compressor

Abstract

The thrust bearing comprises a bearing body, thrust pads, a fixing ring, level blocks, adjusting gaskets, screws, O-shaped rings and pins, the thrust pads are installed in a groove of the fixing ring at equal intervals, the level blocks are arranged in the fixing ring, one end of each level block makes contact with the spherical surface of the corresponding thrust pad, and the other end of each level block makes contact with the spherical surface of the corresponding adjusting gasket. Grooves for installing O-shaped rings are formed in the outer rings of the fixing rings and the outer rings of the thrust pads, through holes for installing pins are designed in the positions, corresponding to the thrust pads, of the inner rings of the fixing rings, and pin holes are designed in the positions, corresponding to the same angles of the through grooves of the fixing rings, of the inner rings of the thrust pads. The thrust bearing disclosed by the invention has the first advantage that if a horizontal subdivision compressor and a vertical subdivision compressor exist on a user site, the thrust bearing has the same size, and the tile of the thrust bearing can replace any damaged tile in the two products in a maintenance process, so that the cost and the time caused by various reasons are saved for a user.
