Core pack thrust bearing

Abstract

The invention belongs to the field of bearings, in particular to a core pack thrust bearing, comprising upper and lower thrust bearings arranged on both sides of a flywheel and a core pack containing the flywheel, upper and lower thrust bearings, the core pack includes a core pack The connection sleeve, the upper core base and the lower core base, the upper and lower core bases are arranged on both sides of the flywheel and respectively connected to the two sides of the core sleeve, between the upper core base and the outer cylinder There is a core package support ring between the core package base and the lower core package base and the end cover, and a slidable sliding piece is provided between the upper and lower core package bases and the core package support ring on the same side; the core package on either side The package support ring is embedded with an elastic component that provides pre-tightening force for the slide and abuts against the outer cylinder or the end cap. The present invention can automatically deflect the thrust bearing to adapt to the deflection of the thrust disc when the shaft is deflected and deformed, so as to ensure that the working plane of the thrust bearing pad is always coplanar with the working plane of the thrust disc, thereby ensuring uniform stress on each pad of the thrust bearing.

Description

technical field [0001] The invention belongs to the field of bearings, in particular to a core-wrapped thrust bearing adapted to shaft deflection and deformation. Background technique [0002] see figure 1 , figure 2 , in the existing thrust bearing structure, the plane where the thrust pad is located is fixed. In the vertical unit, the plane where the thrust pad is located is horizontal; in the horizontal unit, the plane where the thrust pad is located is vertical. When shaft 4 deflects and deforms, the flywheel 2 and thrust disc 3 that are shrink-fitted on shaft 4 will be deflected, while the plane where the thrust pad is located remains vertical or horizontal. In this case, the stress uniformity of each pad of the thrust bearing 27 is destroyed, which is easy to cause damage to the thrust bearing 27 . exist figure 2 The deflection of the thrust disc 3 can be clearly seen in , while the working plane of the thrust bearing 27 remains vertical, which will inevitably l...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the service life of the thrust bearing is reduced due to uneven force on each pad when the shaft is deflected and deformed in the existing thrust bearing, the purpose of the present invention is to provide a core-packed thrust bearing
