[0002] In the existing transmission process, in order to prevent the transmission member from directly contacting the fixed frame, a gasket is usually placed on the transmission member to prevent the transmission member from being damaged by friction with the fixed frame. However, the current gaskets have poor wear resistance and need to be replaced frequently. Summary of the invention

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

[0004] A metal gasket body, wherein the middle portion of the metal gasket body is hollowed out;

[0005] PTFE layer: The PTFE layer covers one side of the metal gasket body and serves as the friction surface of the planetary gasket.

[0006] Furthermore, the material of the metal gasket body is low carbon steel.

[0007] Furthermore, four installation grooves are provided on the middle inner wall of the metal gasket body, and the installation grooves are connected with the middle hollow part.

[0008] Furthermore, four mounting grooves are arranged in a circular array on the middle inner wall of the metal gasket body.

[0009] Furthermore, the thickness of the PTFE layer is 0.4 to 0.6 mm.

[0010] Furthermore, the thickness of the metal gasket body is 1.4-1.6 mm.

[0011] According to a planetary gasket of an embodiment of the utility model, a wear-resistant PTFE layer is arranged on one side of the metal gasket body as the friction surface of the planetary gasket, thereby effectively solving the problem of poor wear resistance of existing gaskets. When in use, it does not need to be replaced frequently and is only arranged on the friction surface, saving costs.

[0012] 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

[0019] Specifically, Figures 1 to 3 As shown, the middle part 11 of the metal gasket body 1 is hollowed out, and the material of the metal gasket body 1 is low-carbon steel; the PTFE layer 2 covers one side of the metal gasket body 1, serving as the friction surface of the planetary gasket to increase the service life of the gasket.

[0020] Further, if Figures 1 to 3 As shown, four mounting grooves 3 are provided on the middle inner wall of the metal gasket body 1, and the mounting grooves 3 are connected to the middle hollow 11. The four mounting grooves 3 are arranged in a circular array on the middle inner wall of the metal gasket body 1, and the setting of the mounting grooves 3 is used for positioning during installation.

[0021] Furthermore, in this embodiment, the thickness of the PTFE layer 2 is 0.4-0.6 mm, and the thickness of the metal gasket body 1 is 1.4-1.6 mm, so as to ensure strength and reliability.

[0022] Above, refer to Figures 1 to 3 A planetary gasket according to an embodiment of the utility model is described, in which a wear-resistant PTFE layer 2 is arranged on one side of a metal gasket body 1 as the friction surface of the planetary gasket, thereby effectively solving the problem of poor wear resistance of existing gaskets. When in use, it does not need to be replaced frequently, and is only arranged on the friction surface, saving costs.

[0023] 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.
