Thrust bearing

Abstract

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.

Description

Technical field [0001] The invention relates to a thrust bearing, in particular to a new structure used when the load is relatively large, the load is uneven, and the load is eccentric. technical background [0002] For the output flange of a vertical gearbox, it is generally difficult to ensure absolute balance due to machining accuracy and placement technology. It is often necessary to support the output flange through a uniformly loaded thrust bearing, especially for large loads, or When the load direction is uncertain, or the load is not stable, the supporting function of the uniform load thrust bearing is particularly important. At present, the support of the thrust bearing generally adopts a plane support or a cylindrical support. In use, the cooling effect of the above two kinds of thrust bearings is poor, and the temperature is high, which easily causes the thrust bearing to burn out and affects the normal operation of the vertical gearbox.
