[0021] Reference Figure 1 , Figure 2 and Figure 3 A pre-finishing rolling group of a high-speed wire rod rolling mill includes a sleeve roller body 1, a mounting bearing 4 and a connecting shaft 5. A mounting hole 2 is opened inside the sleeve roller body 1, and mounting bearings 4 are installed at both ends of the mounting hole 2. The inner rings of the two mounting bearings 4 are fixedly sleeved on the outer surface of the connecting shaft 5, and the connecting shaft 5 penetrates through the sleeve roller body 1. A liquid inlet 6 is fixed at one end of the sleeve roller body 1, and a sealing cover 7 is threadedly sleeved on the liquid inlet 6. A liquid guide channel 8 is opened through the sleeve roller body 1 on the side of the liquid inlet 6, and an outer liquid guide ring 9 is opened inside the sleeve roller body 1 at the end of the liquid guide channel 8 away from the liquid inlet 6, and a diversion channel 13 is symmetrically opened on the inner side of the outer liquid guide ring 9.

[0022] Specifically, when it is necessary to lubricate the inner side of the mounting bearing 4, screw the sealing cover 7, open the liquid inlet 6, and introduce the lubricating oil into the outer liquid guide ring channel 9 through the liquid guide channel 8, and then divert it to the inside of the diversion channel 13 through the outer liquid guide ring channel 9, and then flow into the inside of the inner liquid guide ring 14 through the diversion channel 13. After being discharged through the inner liquid guide ring 14, the inner side of the mounting bearing 4 is lubricated and maintained.

[0023] As an optimization solution, Figure 3As shown, anti-slip sealing rubber sleeves 3 are adhesively fixed to the inner surfaces at both ends of the mounting hole 2, and the inner diameters of the inner circles of the anti-slip sealing rubber sleeves 3 are equal to the outer diameters of the mounting bearings 4. An outer support ring 10 is fixed to the inner side of the middle of the mounting hole 2. The inner diameter of the inner circle of the outer support ring 10 is smaller than the outer diameter of the opening of the mounting bearing 4. The outer diameter of the inner support ring 11 is larger than the inner diameter of the opening of the inner support ring 11. The inner support ring 11 is sleeved inside the outer support ring 10. The inner support ring 11 is arranged in a ring shape for cooperating with the connecting shaft 5. The lengths of the outer support ring 10 and the inner support ring 11 are smaller than the distance between the two mounting bearings 4. The outer surface of the inner support ring 11 is fixedly connected to the inner wall of the outer support ring 10 through a connecting rod 12.

Liquid outlet holes 15 are opened through the inner sides of each inner liquid guide ring 14, and the liquid outlet holes 15 extend to between the outer surface of the inner support ring 11 and the surface of the outer support ring 10.

[0024] Specifically, when the lubricating oil is discharged through the inner liquid guide ring 14, under the guidance of the outer support ring 10 and the inner support ring 11, it can quickly enter the opening of the mounting bearing 4, so as to lubricate the inner side of the mounting bearing 4, ensure the accuracy of lubrication, and the anti-slip sealing rubber sleeve 3 increases the sealing performance between the mounting hole 2 and the mounting bearing 4, avoiding the outflow of the lubricating oil through the mounting hole 2.
