[0019] The following will be combined with the drawings in 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 in 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.

[0020] See also Figure 1-4 The utility model provides a technical solution for a wear-resistant aluminum bushing structure:

[0021] according to Figure 1-4 As shown, it includes an aluminum bushing outer ring 1 and a wear-resistant inner ring 3. The wear-resistant inner ring 3 is nested on the inner wall of the aluminum bushing outer ring 1. The inner wall of the wear-resistant inner ring 3 is equidistantly fixed with evenly distributed wear-resistant strips 4. The surface of the aluminum bushing outer ring 1 is fixed with evenly distributed outer fixing rings 2.

[0022] Specifically, the aluminum bushing structure effectively improves the wear resistance of the aluminum bushing through the cooperation of the aluminum bushing outer ring 1 and the wear-resistant inner ring 3, and evenly distributed wear-resistant strips 4 are fixed on the inner wall of the wear-resistant inner ring 3, thereby increasing the service life of the aluminum bushing.

[0023] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an annular flow channel 10 is provided inside the outer fixing ring 2 , an oil injection hole 7 communicating with the annular flow channel 10 is provided on the surface of the outer fixing ring 2 , and a sealing plug 8 is nested inside the oil injection hole 7 .

[0024] Evenly distributed oil seepage holes 9 are provided on both sides of the inner wall of the annular flow channel 10 .

[0025] Specifically, by providing the annular flow channel 10 and the oil seepage holes 9 provided on both sides of the annular flow channel 10, the worn parts can be lubricated, thereby reducing wear and improving the service life.

[0026] The outer wall of the wear-resistant inner ring 3 is fixed with uniformly distributed limiting strips 6 at equal intervals, and the inner wall of the aluminum bushing outer ring 1 is provided with a plurality of limiting grooves 5 matched with the limiting strips 6 at equal intervals, and the limiting strips 6 are nested and connected with the limiting grooves 5 .

[0027] The surface of the limiting strip 6 is provided with uniformly distributed anti-skid patterns. Specifically, the anti-skid patterns provided on the surface of the limiting strip 6 increase the firmness of the nesting of the limiting strip 6 and the limiting groove 5.

[0028] The inner diameter of the aluminum bushing outer ring 1 is adapted to the outer diameter of the wear-resistant inner ring 3. Specifically, by adapting the inner diameter of the aluminum bushing outer ring 1 to the outer diameter of the wear-resistant inner ring 3, the gap at the connection between the aluminum bushing outer ring 1 and the wear-resistant inner ring 3 is effectively reduced.

[0029] Working principle: The utility model has a wear-resistant aluminum bushing structure. When the wear-resistant aluminum bushing structure is used, a wear-resistant inner ring 3 is provided inside the outer ring 1 of the aluminum bushing. The wear-resistant strips 4 arranged on the inner wall of the wear-resistant inner ring 3 increase the wear resistance of the aluminum bushing and the sleeve-mounted parts. At the same time, an annular flow channel 10 is opened in the outer fixing ring 2 outside the aluminum bushing. The oil seepage holes 9 opened on both sides of the annular flow channel 10 can lubricate the worn parts of the aluminum bushing, thereby reducing wear and increasing the service life of the aluminum bushing.
