Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to a bimetallic gasket with positioning function. Background Art

[0002] Friction and sealing components are often required in mechanical equipment. Currently, both friction and sealing components use single metal gaskets, which are easily worn after long-term use. In addition, the gaskets do not have a positioning function and are not suitable for some scenarios where the gaskets need to remain stationary. Therefore, a bimetallic gasket with positioning is designed. Summary of the invention

[0003] According to an embodiment of the utility model, a bimetallic gasket with positioning is provided, comprising:

[0004] A metal gasket body, wherein a hollow hole is provided in the middle of the metal gasket body;

[0005] A positioning protrusion, which is arranged on the gasket body and protrudes toward one side of the gasket body;

[0006] The metal wear-resistant layer is arranged on the other side of the metal gasket body.

[0007] Furthermore, the material of the metal gasket body is low carbon steel.

[0008] Furthermore, the material of the metal wear-resistant layer is CuSn8Ni.

[0009] Furthermore, the metal gasket body and the positioning protrusion are integrally formed.

[0010] Furthermore, three oil grooves are evenly arranged on the metal wear-resistant layer.

[0011] Furthermore, the thickness of the metal gasket body is 1.4-1.6 mm.

[0012] Furthermore, the thickness of the metal wear-resistant layer is 0.4-0.6 mm.

[0013] A bimetallic gasket with positioning according to an embodiment of the utility model has good wear resistance by providing a metal wear-resistant layer of CuSn8Ni, thereby improving the service life of the gasket, and has a positioning protrusion that can play a role in positioning when the gasket is installed.

[0014] It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the technology as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0019] First, combine Figures 1 to 3 A bimetallic gasket with positioning according to an embodiment of the utility model is described, which is used for friction and sealing and has a wide range of application scenarios.

[0020] like Figures 1 to 3 As shown, a bimetallic gasket with positioning according to an embodiment of the utility model comprises a metal gasket body 1 , a positioning protrusion 3 and a metal wear-resistant layer 2 .

[0021] like Figures 1 to 3 As shown, a hollow hole 11 is provided in the middle of the metal gasket body 1, and the material of the metal gasket body 1 is low carbon steel; the positioning protrusion 3 is arranged on the gasket body and protrudes toward one side of the gasket body; the metal wear-resistant layer 2 is arranged on the other side of the metal gasket body 1, and the material of the metal wear-resistant layer 2 is CuSn8Ni.

[0022] Furthermore, in this embodiment, the metal gasket body 1 and the positioning protrusion 3 are integrally formed to ensure the stability and strength of the structure.

[0023] Further, if Figures 1 to 3 As shown, three oil grooves 4 are evenly arranged on the metal wear-resistant layer 2, which can form an oil layer after the gasket is installed to store oil and reduce friction.

[0024] Furthermore, in this embodiment, the thickness of the metal gasket body 1 is 1.4-1.6 mm, and the thickness of the metal wear-resistant layer 2 is 0.4-0.6 mm.

[0025] Above, refer to Figures 1 to 3 A bimetallic gasket with positioning according to an embodiment of the utility model is described. By setting a metal wear-resistant layer 2 of CuSn8Ni, it has good wear resistance and improves the service life of the gasket. It also has a positioning protrusion 3, which can play a positioning role when the gasket is installed.

[0026] It should be noted that, in this specification, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprises..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
