[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and in the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0020] For example, Figure 1 and Figure 2As shown, the application provides a wear-resistant filter bushing, which comprises a body 1, an oil groove is formed in the body 1, and lubricating oil is added in the bushing, most of the lubricating oil is in the oil groove, and a contact part 3 is formed in the center of the oil groove. When the bushing is used, the inner side surface of the body 1 and the surface of the contact part 3 are in contact with the shaft, and the inner side surface of the body 1 and the surface of the contact part 3 are provided with a wear-resistant coating. In this embodiment, the wear-resistant coating is selected to be a GT700 wear-resistant and corrosion-resistant coating, so that the wear resistance and service life of the bushing are improved.

[0021] As shown in Figure 1 and Figure 2 The contact part 3 and the side wall of the oil groove form a containing opening 4, a plurality of through holes 5 are arranged on the contact part 3 in a spaced manner, the through holes 5 penetrate the contact part 3 and are in communication with the containing opening 4, and a plurality of flow guide protrusions 6 are arranged on the side wall of the oil groove in a spaced manner with the body 1 as the center. Part of the flow guide protrusions 6 is located outside the containing opening 4, and the other part is located inside the containing opening 4. A sponge pad 7 is arranged in the containing opening 4, and the sponge pad 7 is inserted between the contact part 3 and the flow guide protrusion 6 in a squeezed and deformed manner until the sponge pad 7 completely enters the containing opening 4. The sponge pad 7 is reset and abuts against the flow guide protrusion 6 and the side wall of the containing opening 4, so that the sponge pad 7 remains in the containing opening 4. At the same time, a notch 8 is formed on one side of the sponge pad 7 close to the flow guide protrusion 6 for inserting the flow guide protrusion 6. The cooperation of the notch 8 and the flow guide protrusion 6 can increase the position stability of the sponge pad 7 in the containing opening 4.

[0022] As shown in Figure 1 and Figure 2 The flow guide protrusions 6 are arranged in an inclined manner, and the inclination direction is consistent with the rotation direction of the bushing. When the lubricating oil flows in the oil groove due to gravity, the lubricating oil is guided by the flow guide protrusions 6 and flows into the containing opening 4, so that the lubricating oil passes through the sponge pad 7. The impurities in the lubricating oil are blocked by the sponge pad 7, thereby filtering the lubricating oil. The flow rate of the lubricating oil is slowed down by the sponge pad 7, and part of the filtered lubricating oil flows out of the containing opening 4 and the sponge pad 7 under the action of gravity and participates in lubrication again. This can reduce the probability of impurities in the lubricating oil contacting the bushing again, increase the wear resistance of the bushing, and improve the lubrication effect.

[0023] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the scope of the present application are also within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application are also considered as the protection scope of the present application.
