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 utility model relates to a bimetal composite tile, concretely relates to bimetal composite sliding bearing tile.
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 utility model discloses a solve the weak point among the prior art, provide a bimetal composite sliding bearing tile fragment, when the operating mode changes or bearing-rotor system stability changes, the temperature of lubricating oil can change thereupon, utilizes the expansion ratio of different metals different under the different temperatures different, through control lubricating oil temperature and flow control tile fragment temperature, realizes the controllable change of tile fragment curvature radius self-adaptation, and then obtains suitable sliding bearing support rigidity and damping, improves sliding bearing's performance.
In order to solve the technical problem, the utility model 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.
Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: a bimetal composite sliding bearing tile, tile inlayer and tile are outer utilizes the welding layer to combine into an organic whole through modes such as brazing, and tile inlayer and the outer metal material of tile and thickness can change according to the demand in addition, through control lubricating oil temperature and flow control tile temperature, realize the controllable change of tile curvature radius self-adaptation, and then obtain suitable sliding bearing support rigidity and damping, improve sliding bearing's performance.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the utility model discloses a bimetal composite sliding bearing tile, including the tile body, the tile body includes tile outer 1, tile inlayer 2, bearing lining 3 and welding layer 4, tile outer 1 utilizes welding layer 4 to combine into an organic whole with tile inlayer 2 through the mode of brazing, and bearing lining 3 forms an organic whole with tile inlayer 2 through centrifugal casting or cladding build-up welding 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 form, and all of the technical matters of the present invention belong to the protection scope of the present invention to any simple modification, equivalent change and modification made by the above embodiments.
Claims (2)
1. The utility model provides a bimetal composite sliding bearing tile, includes the tile body, its characterized in that: the tile body includes that the tile is outer, tile inlayer, bearing lining and welded layer, the tile is outer to utilize the welded layer to combine to become an organic whole through the mode of brazing with the tile inlayer, and the bearing lining forms an organic whole through centrifugal casting or cladding build-up welding mode and tile inlayer.
2. A bi-metallic composite plain bearing pad according to claim 1, wherein: 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.
