Problems solved by technology

When the thrust bearing is working, the thrust pad bears the axial load, but because it is fixedly installed in the bearing housing, the magnitude and direction of the load cannot be adjusted
In actual work, when the axial load is too large, it will have a great impact on the wear of the wear-resistant layer of the working thrust pad. If it is in this situation for a long time, it is easy to cause the working thrust pad to burn due to heat.

Abstract

The invention relates to a thrust bearing for generator set, which comprises a bearing shell and a thrust shoe and an oil seal provided in the bearing shell, wherein the thrust shoe is circumferentially provided at two sides of the shaft shoulder of a rotating shaft and bearing the axial thrust of the rotating shaft, an equalizing device is provided between the thrust shoe and bearing shell and composed of six upper equalizing bridge blocks, eight lower equalizing bridge blocks and an equalizing bridge housing, and the upper and the lower equalizing bridge blocks are in sectoral shape and circumferentially and symmetrically disposed at the two sides of the thrust shoe. The structure has the advantages of stable and reliable operation, long service life of the thrust shoe, and convenient repairing; can prevent thrust shoe burnt phenomenon due to uneven stress; and is easy to spread and apply.

Description

technical field [0001] The invention relates to a bearing, in particular to a thrust bearing structure for a generator set. Background technique [0002] At present, the thrust bearing used in the generator set adopts a fixed thrust shoe. With reference to accompanying drawing 7, the thrust bearing includes a bearing housing (51) with an integrated structure, a positioning shoe (57) and a working shoe (67) with a wear-resistant layer. An oil deflector ring (59), a mounting ring (55) and a measuring ring (60) are provided, and the positioning shoe (57) and the working shoe (67) are connected to the mounting ring (55) and the measuring ring (60) through the pin (52) respectively. Fixed connection. This kind structure positioning tile (57) and work tile (67) are fixed. When the thrust bearing is working, the thrust pad bears the axial load, but because it is fixedly installed in the bearing housing, the size and direction of the load cannot be adjusted. In actual work, when ...
