AI Technical Summary
The thrust pads on the rotating thrust disc or stationary support ring of existing thrust bearings are fixed pad structures, which are prone to warping and deformation after welding, making it difficult to guarantee the flatness and parallelism of the friction surface. This results in difficult post-processing, and damage to the thrust pads requires replacement of the entire bearing, leading to serious waste of resources and high maintenance costs.
The structure employs a combination of lower and upper embedded shock-absorbing alloy plates, with a composite rubber vibration-damping and energy-absorbing layer between them. The bearing is fixed by bolts to a stepped hole seat with embedded bearings, achieving flexible support and shock absorption.
It effectively reduces wear under high load conditions, increases bearing life, reduces maintenance costs, and reduces resource waste.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of adjustable bearing base technology, and in particular to an adjustable bearing base suitable for high load environments. Background Technology
[0002] The thrust pads on the rotating thrust disc or stationary support ring of a thrust bearing are mostly fixed pad structures, directly installed on the bottom support ring via welding. During the high-temperature welding process, these support rings will warp and deform. After welding, the height difference of the circumferentially distributed pads on the rotating thrust disc or stationary support ring is relatively large, making it difficult to guarantee the flatness and parallelism requirements of the friction surface. Therefore, the entire friction surface formed by the thrust pads or bearing pads needs to be post-processed after welding. Because these pads are made of hard or superhard materials, the post-processing is extremely difficult, and the bearing manufacturing process is complex. Furthermore, if any thrust pad is damaged during use, the bearing must be replaced, resulting in significant resource waste and high bearing maintenance costs.
[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
[0004] An adjustable bearing base suitable for high-load environments includes a base plate with bolted connections and a lower embedded damping alloy plate fixed to the base plate. The upper end face of the lower embedded damping alloy plate is provided with arrayed cones. The base plate also includes an upper embedded damping alloy plate that is embedded with the lower embedded damping alloy plate. The lower end face of the upper embedded damping alloy plate is also provided with arrayed cones. A composite rubber vibration-damping and energy-absorbing layer is bonded between the upper and lower embedded damping alloy plates. A bearing stepped hole seat is fixedly provided on the upper end face of the upper embedded damping alloy plate, and a bearing is embedded and fixedly installed in the bearing stepped hole seat.
[0005] Preferably, the bearing and the bearing stepped bore seat are interference fits.
