Core pack thrust bearing

Abstract

The invention belongs to the field of bearings, and particularly relates to a core pack thrust bearing. The core pack thrust bearing comprises an upper thrust bearing body, a lower thrust bearing body and a core pack, wherein the upper thrust bearing body and the lower thrust bearing body are arranged on two sides of a flywheel; the core pack accommodates the flywheel, the upper thrust bearing body and the lower thrust bearing body; the core pack comprises a core pack connecting sleeve, an upper core pack pedestal and a lower core pack pedestal; the upper core pack pedestal and the lower core pack pedestal are arranged on two sides of the flywheel and are respectively connected with two sides of the core pack connecting sleeve; core pack supporting rings are respectively arranged between the upper core pack pedestal and an outer barrel and between the lower core pack pedestal and an end cap; and slidable sheets are respectively arranged between the upper core pack pedestal and the core pack supporting ring which are positioned on the same side and between the lower core pack pedestal and the core pack supporting ring which are positioned on the same side. An elastic component which provides a pretightening force for the corresponding slidable sheet and is abutted to the outer barrel or the end cap is inlaid in the core pack supporting ring on the optional side. When a shaft flexibly deforms, the thrust bearing can deflect automatically to adapt to deflection of a thrust plate, the working plane of a thrust bearing pad can be always coplanar with the working plane of the thrust plate, and therefore, uniform stress of various pads of the thrust bearing is guaranteed.

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
