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; theindependent 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 bearingsare 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, especially a novel structure used when the load is relatively large, the load is uneven, and the load is uneven. technical background [0002] For the output flange of the vertical gearbox, due to the machining accuracy and placement process, it is generally difficult to ensure absolute balance. It is often necessary to support the output flange through a thrust bearing that can evenly load, especially for large loads, or When the load direction is uncertain, or the load is in an unstable state such as partial load, the support function of the load-sharing thrust bearing is particularly important. At present, the support of the thrust bearing is generally supported by a plane support or a cylinder. During use, the cooling effect of the above two thrust bearings is poor, and the temperature is high, which may easily cause the thrust bearing to burn out and affect the normal operation of the vertical gearbox. ...
