Abstract
A bimetal composite sliding bearing pad comprises a pad body, wherein the pad body comprises a pad outer layer, a pad inner layer, a bearing lining layer and a welding layer; in summary, the invention discloses a bimetal composite sliding bearing tile, which utilizes the difference of different metal expansion rates to realize the controlled change of the curvature radius of the tile at different temperatures, thereby improving the performance of a sliding bearing; the method is mainly used for preparing the tilting pad sliding bearing.
Description
Technical Field
The invention relates to a bimetal composite tile block, in particular to a bimetal composite sliding bearing tile block.
Background
The sliding bearing has the advantages of low noise, long service life, stable and reliable operation, small vibration and the like, and is widely applied to rotating machinery under low-speed heavy-load working conditions and high-speed working conditions. The sliding bearing is used as a main source of rigidity and damping of the bearing-rotor system, and the performance of the sliding bearing influences the stable operation of the rotor-bearing system; after the common tile is manufactured and put into use, if the abrasion and the structural deformation are not considered, the structural parameters of the common tile basically cannot be changed, and the self-adaptive change of the parameters cannot be realized when the working condition is changed or the stability of a bearing-rotor system is changed.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides a bimetal composite sliding bearing pad, when the working condition is changed or the stability of a bearing-rotor system is changed, the temperature of lubricating oil is changed along with the change of the working condition, the self-adaption controllable change of the curvature radius of the pad is realized by controlling the temperature of the lubricating oil and the temperature of the pad through controlling the different expansion rates of different metals at different temperatures, and further, the proper supporting rigidity and damping of the sliding bearing are obtained, and the performance of the sliding bearing is improved.
In order to solve the technical problems, the invention adopts the following technical scheme: the utility model provides a bimetal composite sliding bearing tile, includes the tile body, the tile body includes tile skin, tile inlayer, bearing lining and welded layer, the outer and the tile inlayer of tile utilize the welded layer to combine into an organic whole through the mode of brazing of tile, and the bearing lining forms integratively through centrifugal casting or cladding build-up welding mode and tile inlayer.
The outer layer of the tile is composed of a plurality of outer layer metals of the tile, and a gap is reserved between every two outer layers.
By adopting the technical scheme, the invention has the following beneficial effects: according to the bimetal composite sliding bearing pad, the inner layer and the outer layer of the pad are combined into a whole by means of brazing and the like through the welding layer, the metal materials and the thicknesses of the inner layer and the outer layer of the pad can be changed according to requirements, the curvature radius of the pad can be adaptively and controllably changed by controlling the temperature of lubricating oil and the temperature of the pad, further, the proper supporting rigidity and damping of the sliding bearing are obtained, and the performance of the sliding bearing is improved. Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
As shown in fig. 1, the bimetal composite sliding bearing pad of the invention comprises a pad body, wherein the pad body comprises a pad outer layer 1, a pad inner layer 2, a bearing lining layer 3 and a welding layer 4, the pad outer layer 1 and the pad inner layer 2 are integrated into a whole by the welding layer 4 in a brazing mode, and the bearing lining layer 3 is integrated with the pad inner layer 2 into a whole in a centrifugal casting or cladding surfacing mode; the tile body is not limited to the composition of only two layers of metal, namely an inner layer and an outer layer, the number of the composite layers of the tile can be multiple, and the layers are integrated in a brazing mode; in order to realize a proper deformation rule of the tile, the number of layers of the tile, the material and the thickness of each layer of metal are determined according to specific working conditions; the geometrical shape, geometrical size and other structures of the pad can be changed according to requirements so as to match the tilting pad sliding bearing with different structural parameters.
The outer layer 1 of the tile is composed of a plurality of outer layers 1 of the tile, and a gap is reserved between every two outer layers of the tile so as to prevent the axial bending deformation of the tile caused by different expansion rates of the inner layer and the outer layer of the tile.
In the using process, the temperature of the pad can be controlled by controlling the temperature and the flow of the lubricating oil of the sliding bearing, the self-adaptive controllable change of the curvature radius of the pad is realized, the proper supporting rigidity and damping of the sliding bearing are further obtained, and the performance of the sliding bearing is improved.
The present embodiment is not intended to limit the shape, material, structure, etc. of the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
