[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: A self-lubricating wear-resistant bearing includes:

[0026] Among them, two grease filling grooves 8 are opened on the inner wall of the inner ring 2, an arc-shaped top block 10 is located inside the grease filling groove 8, an arc-shaped filter plate 9 is fixedly connected to the outer wall of the inner ring 2 to extrude the lubricating grease from the inside of the grease filling groove 8, two T-shaped blocks 3 are fixedly connected to the inner wall of the inner ring 2, an arc-shaped mounting block 4 is located on the outer wall of the annular wear-resistant sheet 5, a screw 7 is arranged on the top side of the arc-shaped mounting block 4, the bottom end of the screw 7 is arranged inside the T-shaped block 3, and the arc-shaped top block 10 is arranged on the side of the arc-shaped mounting block 4 away from the annular wear-resistant sheet 5 for fixing the arc-shaped top block 10. The separated sides of the two arc-shaped top blocks 10 are arranged on the adjacent sides of the two arc-shaped filter plates 9 to improve the wear resistance of the bearing;

[0027] Specifically, when adding grease to the bearing, the grease can be first squeezed into the interior of the grease filling groove 8, then the arc-shaped top block 10 is inserted into the interior of the grease filling groove 8, and then the arc-shaped mounting block 4 and the annular wear-resistant sheet 5 are connected between the screw 7 and the T-shaped block 3 to fix the arc-shaped top block 10 in the interior of the grease filling groove 8 by using the arc-shaped mounting block 4. When the arc-shaped top block 10 is inserted into the interior of the grease filling groove 8, the grease inside the arc-shaped top block 10 is extruded from the arc-shaped filter plate 9, and the grease is smeared on the outer wall of the ball 6. Then, by rotating the inner ring 2, the ball 6 with the smeared grease is smeared on the annular raceway 11 on the side close to each other between the outer ring 1 and the inner ring 2, so as to evenly smear the grease on the outer wall of the ball 6 and inside the annular raceway 11, achieving the lubrication of the bearing, improving the lubrication effect of the bearing, avoiding the incomplete lubrication of the bearing when using grease, which may affect the lubrication of the bearing. At the same time, when the grease inside the grease filling groove 8 is extruded by the insertion of the arc-shaped top block 10, the impurities existing in the grease are filtered between the arc-shaped filter plate 9 and the arc-shaped top block 10 through the arc-shaped filter plate 9, preventing the impurities in the grease from contacting the ball 6 and the annular raceway 11 and causing wear to the ball 6 and the annular raceway 11, thus affecting the service life of the bearing.

[0028] Refer to Figures 1 - 3 , wherein there are a plurality of balls 6 arranged inside the annular raceway 11 on the side close to each other between the outer ring 1 and the inner ring 2, which are used for the rotation of the inner ring 2 on the inner wall of the outer ring 1. The annular wear-resistant sheet 5 is made of stainless steel to improve the service life of the bearing;

[0029] Specifically, the balls 6 can provide support for the rotation of the outer ring 1 and the inner ring 2, and the friction can be reduced by the rotation of the balls 6. At the same time, the annular wear-resistant sheet 5 is made of stainless steel. Since stainless steel not only has good corrosion resistance but also can obtain relatively high hardness after appropriate heat treatment, the wear resistance of the bearing can be further improved, which is convenient for extending the service life of the bearing.

[0030] Working principle: First, squeeze the grease into the interior of the grease filling groove 8, then insert the arc-shaped top block 10 into the interior of the grease filling groove 8. Next, connect the arc-shaped mounting block 4 and the annular wear-resistant sheet 5 through the screws 7 and the T-shaped block 3, and use the arc-shaped mounting block 4 to fix the arc-shaped top block 10 inside the grease filling groove 8. Then, filter the impurities in the grease through the arc-shaped filter plate 9 to the space between the arc-shaped filter plate 9 and the arc-shaped top block 10, to prevent the impurities in the grease from contacting the ball 6 and the annular raceway 11 and causing wear to the ball 6 and the annular raceway 11. When the grease is extruded from the arc-shaped filter plate 9, apply the grease to the outer wall of the ball 6. Then, the ball 6 can provide support for the rotation of the outer ring 1 and the inner ring 2. By rotating the inner ring 2, the rolling of the ball 6 inside the annular raceway 11 can be controlled, and the grease adhered to the outer wall of the ball 6 can be evenly applied to the inside of the annular raceway 11, thereby realizing the even application of the grease inside the bearing.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
