[0023] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0024] like Figure 1-3 As shown, the utility model includes a connecting sleeve 1, a sprocket 2 and a connecting plate 3 fixed to the connecting sleeve 1, and a mounting hole 4 is provided on the connecting plate 3. In this embodiment, the connecting sleeve 1, the sprocket 2 and the connecting plate 3 are integrally formed. A connecting portion 5 protruding outward is provided on the connecting plate 3, and there are three connecting portions 5. The three connecting portions 5 are distributed in a circular array with the connecting sleeve 1 as the center, and a mounting hole 4 is provided on each connecting portion 5.

[0025] An oil filling groove 6 is arranged on the upper end surface of the connecting sleeve 1, and an opening is arranged inside the oil filling groove 6 and is connected with the inner side of the connecting sleeve 1 through the opening. In the present embodiment, there are three evenly distributed oil filling grooves 6, and an inclined slope surface with a high outer side and a low inner side is arranged on the inner periphery of the upper end surface of the connecting sleeve 1 to guide the lubricating oil.

[0026] An oil storage groove 7 is arranged on the lower end surface of the connecting sleeve 1, and an opening is arranged inside the oil storage groove 7 and is connected with the inner side of the connecting sleeve 1 through the opening. In the present embodiment, there are three evenly distributed oil storage grooves 7, and an inclined slope surface with a lower outer side and a higher inner side is arranged on the inner periphery of the lower end surface of the connecting sleeve 1 to guide the lubricating oil.

[0027] A wear-resistant copper sleeve 8 is arranged inside the connecting sleeve 1. The upper end of the wear-resistant copper sleeve 8 is an oil-conducting inclined surface with a high outer side and a low inner side, and the lower end is an oil-conducting inclined surface with a low outer side and a high inner side.

[0028] In this embodiment, the outer side of the oil filling groove 6 is open to facilitate oil filling, and the outer side of the oil storage groove 7 is blocked to facilitate oil storage.

[0029] When in use, an oil spray head is installed above the upper end surface of the connecting sleeve 1, and oil is sprayed to the upper end surface of the connecting sleeve 1 at any time through the oil spray head, and the lubricating oil flows to the inner side of the wear-resistant copper sleeve 8 through the oil filling groove 6. When the utility model is in a rotating state during operation, the oil spray head will spray oil evenly to the upper end surface of the connecting sleeve 1, and evenly flow into the inner side of the wear-resistant copper sleeve 8 through the three oil filling grooves 6, thereby improving the uniformity of oil filling and being able to fill oil at any time, without stopping the machine for manual oil filling, and convenient operation. The lubricating oil flowing into the inner side of the wear-resistant copper sleeve 8 will flow downward into the oil storage groove 7 for storage, thereby preventing the lubricating oil from flowing away and improving the lubrication effect. The sprocket 2 structure of the utility model ensures that there is always no lack of lubricating oil in the wear-resistant copper sleeve 8, and the lubrication effect is good, thereby extending the service life of the sprocket 2 structure.
