[0032] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the specific embodiment of the present invention, see Figure 1-Figure 6 , a piston guide ring, comprising:

[0034] The guide ring body 1 is provided with a cutout 11. Figure 1 ;

[0035] In order to improve the wear resistance of the piston guide ring, a protective layer is also provided;

[0036] See Figure 6 , the protective layer is a dipped fiber cloth 5;

[0037] See Figure 3 The protective layer is provided on both the inner and outer sides of the guide ring body 1, wherein the dipped fiber cloth on the inner side forms a high-load supporting layer 2, and the dipped fiber cloth on the outer side forms a protective layer 3, thereby enhancing the anti-wear performance of both the inner and outer sides of the guide ring body.

[0038] In the specific embodiment of the present invention, see Figure 1-Figure 6 The dipped fiber cloth 5 includes a colloid and a fiber cloth 4, the fiber cloth 4 is dipped in the colloid, and the fiber cloth structure is shown in FIG. Figure 4 and Figure 5 ;

[0039] The fiber cloth in the high-load support layer is different from the fiber cloth in the protective layer;

[0040] The fiber cloth in the high-load support layer is made of glass fiber, and the impregnation is thermosetting resin and additives, and the additives are auxiliary agents; the characteristics are strong rigidity, relatively high friction coefficient, and insufficient wear resistance;

[0041] The fiber cloth in the protective layer is made of polyester fiber, cotton fiber, linen fiber, aramid fiber, etc. (excluding glass fiber), and the impregnation is thermosetting resin and additives, and the additives are self-lubricants or auxiliary agents; the friction coefficient is extremely low and the wear resistance is excellent, but the rigidity is not strong.

[0042] In the specific embodiment of the present utility model, see Figure 5 The fiber cloth 4 includes a first texture 41 and a second texture 42, wherein the first texture and the second texture intersect each other;

[0043] Ensure the wear resistance and stability of the fiber cloth 4.

[0044] In the specific embodiment of the present utility model, see Figure 1-Figure 6 , see Figure 1 , Figure 4 , Figure 5 , the inclination angle of the one-way texture relative to the horizontal plane when the guide ring body is placed horizontally is the same as the inclination angle of the cutout of the guide ring body;

[0045] The supplementary angle of the inclination angle is greater than 90°;

[0046] The angle setting of the texture along the way is intended to reduce friction;

[0047] This is not a high requirement for high-load support layers.

[0048] In the specific embodiment of the present utility model, see Figure 1-Figure 6 , the second texture 42 has the same inclination direction as the first texture 41;

[0049] The inclination angle of the second-path texture 42 relative to the horizontal plane when the guide ring body 1 is placed horizontally is smaller than the inclination angle of the first-path texture 41 relative to the horizontal plane when the guide ring body 1 is placed horizontally;

[0050] That is, the first texture 41 and the second texture 42 are in the same inclination direction as the cutout, which can effectively reduce friction;

[0051] For the high-load supporting layer 2, this requirement is not so high.

[0052] In the specific embodiment of the present utility model, see Figure 1-Figure 6 , see Figure 6, the inner and outer sides of the guide ring body 1 are both provided with numerous first anti-slipping textures 101, and the numerous first anti-slipping textures have the same inclination angle;

[0053] A first anti-slip groove 102 is formed between adjacent first anti-slip textures 101;

[0054] On one side of the dipped fiber cloth 5 connected to the inner circumference of the guide ring body 1 or the outer circumference of the guide ring body 1, numerous second anti-stripping textures 501 are provided, and the numerous second anti-stripping textures 501 have the same inclination angle;

[0055] A second anti-slip groove 502 is formed between adjacent second anti-slip textures 501;

[0056] The second anti-stripping texture 501 has the same inclination angle as the first anti-stripping texture 101;

[0057] The first anti-slip texture 101 cooperates with the second anti-slip groove 502;

[0058] The second anti-slip texture 501 cooperates with the first anti-slip groove 102;

[0059] The first anti-slip texture 101 and the second anti-slip groove 502 and the first anti-slip groove 102 and the second anti-slip texture 501 are arranged to cooperate with each other, which can effectively increase the connection area between the guide ring body 1 and the protective layer and improve the stability of the connection;

[0060] The height of the first anti-shedding texture and the second anti-shedding texture is relatively small, for example, 0.01 mm;

[0061] Similarly, the depths of the first anti-slip groove and the second anti-slip groove are relatively small, such as 0.01 mm.

[0062] The second anti-slipping texture and the second anti-slipping groove on the dipped fiber cloth on the inner and outer sides of the guide ring body are arranged in opposite positions, that is, the production processes of the inner and outer dipped fiber cloths are different. When the dipped fiber cloths are placed horizontally and the texture directions are the same, the dipped fiber cloth used on the inner side of the guide ring body is provided with the second anti-slipping texture and the second anti-slipping groove on the upper surface, and the fiber cloth used on the outer side of the guide ring body is provided with the second anti-slipping texture and the second anti-slipping groove on the lower surface.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
