[0029] Example, see Figure 1~Figure 2 , which is an embodiment of the utility model, proposes an oil and gas improvement device for the degreasing roller of a reversible rolling mill, including a roller shaft 1, a roller 2, and a bearing 3. The roller 2 is coaxially arranged with the roller shaft 1 and is located on the periphery of the roller shaft 1; the bearing 3 is arranged between the roller shaft 1 and the roller 2, and the roller 2 is rotatably connected to the roller shaft 1 by means of the bearing 3. An inner oil and gas hole 4 is provided on the inner side wall of the bearing 3, and an inner oil and gas channel 5 is provided on the end face of the roller shaft 1. The inner oil and gas channel 5 is connected to the inner oil and gas hole 4.

[0030] In this embodiment, bearings 3 are disposed between each end of the roller shaft 1 and the roller drum 2. Both ends of the roller shaft 1 are exposed outside the roller drum 2. Internal oil and gas passages 5 are located on each end surface of the roller shaft 1. One end of an internal oil and gas hole 4 communicates with the inner end of the internal oil and gas passage 5, while the other end of the internal oil and gas hole 4 extends between the inner and outer rings of the bearing 3. Connecting the outer end of the internal oil and gas passage 5 to an oil and gas delivery device allows the oil and gas delivered by the oil and gas delivery device to pass through the internal oil and gas passage 5, enter the internal oil and gas hole 4, and then reach between the inner and outer rings of the bearing 3, thereby lubricating the bearing 3. This effectively prevents damage to the bearing 3 due to insufficient lubrication, reduces maintenance costs, minimizes downtime for repairs, and improves production efficiency.

[0031] Further, such as Figure 1 and Figure 2 As shown, the outer wall of the bearing 3 is provided with an external oil and gas hole 6, and the end surface of the roller 2 is provided with an external oil and gas channel 7, which is connected to the external oil and gas hole 6. This allows oil and gas to enter the external oil and gas hole 6 from the external oil and gas channel 7 and then reach between the inner and outer rings of the bearing 3. In combination with the internal oil and gas hole 4, this can further enhance the lubrication effect of the bearing 3, provide more comprehensive lubrication for the bearing 3, and prevent the bearing 3 from being damaged due to insufficient lubrication.

[0032] Further, such as Figure 3 As shown, the roller 1 further includes a connector 8, one end of which is disposed at the end of the roller 1 and contacts the end surface of the roller 2. The other end of the connector 8 has an oil and gas delivery groove 9, and a delivery channel 10 is provided on the connector 8. One end of the delivery channel 10 is connected to the oil and gas delivery groove 9, and the other end of the delivery channel 10 is connected to the internal oil and gas channel 5. The connector 8 serves as a bridge, facilitating the connection between the roller 1 and the oil and gas delivery equipment. The oil and gas from the oil and gas delivery equipment are concentrated in the oil and gas delivery groove 9, and then accurately delivered to the internal oil and gas channel 5 through the delivery channel 10, ensuring that the oil and gas can smoothly reach the space between the inner and outer rings of the bearing 3, providing comprehensive lubrication for the bearing 3 and effectively preventing damage to the bearing 3 due to insufficient lubrication. This can reduce maintenance costs, reduce the number of downtimes for maintenance, and improve production efficiency. The oil and gas delivery groove 9 of the connector 8 has threads on the sidewall, which can be threadedly connected to the oil and gas delivery equipment. The connection is firm and reliable, and assembly and disassembly are convenient and quick, saving time and effort.

[0033] Further, such as Figure 1 and Figure 2As shown, the circumferential surface of the roller shaft 1 has a retaining groove located outside the bearing 3. It also includes an internal retaining spring 11, which engages with the retaining groove and contacts the bearing 3. The internal retaining spring 11 axially positions the bearing 3, preventing axial movement of the bearing 3 on the roller shaft 1. This ensures the stability of the bearing 3 during operation, ensures its normal operation, reduces damage caused by unstable bearing position, and reduces maintenance costs.

[0034] Further, such as Figure 1 and Figure 2 As shown, a transparent cover 12 is also included. This cover is positioned between the roller shaft 1 and the drum 2 and outside the bearing 3. This protects the bearing 3 by preventing foreign matter from entering the bearing 3. Its transparency also allows operators to observe the operating status of the bearing 3 and identify potential problems. When an inner retaining spring 11 is present, the transparent cover 12 is positioned outside the inner retaining spring 11.

[0035] Further, such as Figure 1 and Figure 2 As shown, the inner wall of the end face of the roller 2 has a receiving groove 13, and the transparent cover 12 is engaged with the receiving groove 13. The roller 2 also includes a retaining ring 14 and an external retaining spring 15. The retaining ring 14 is arranged on the periphery of the roller shaft 1 and located within the receiving groove 13. The inner end face of the retaining ring 14 contacts the transparent cover 12. The external retaining spring 15 is located within the receiving groove 13 and is engaged between the retaining ring 14 and the roller 2. The retaining ring 14 and the external retaining spring 15 cooperate to fix the transparent cover 12, ensuring that the transparent cover 12 is stable and will not shift due to factors such as vibration generated by the operation of the equipment, thereby ensuring that the transparent cover 12 can continue to effectively protect the bearing 3 and facilitate observation.

[0036] Further, such as Figure 1 and Figure 2 As shown, the inner wall of the roller 2 is provided with a limiting groove, and the external retaining spring 15 is engaged with the limiting groove, which can further enhance the fixing effect of the external retaining spring 15, prevent the external retaining spring 15 from being displaced during operation, and ensure the fixing effect of the retaining ring 14 on the transparent cover 12, thereby ensuring the stability of the entire structure.

[0037] Further, such as Figure 1 and Figure 2 As shown, the inner end of the transparent cover 12 has a protruding inner retaining ring 16. The inner retaining ring 16 is located inside the receiving groove 13, and the outer wall of the inner retaining ring 16 contacts the inner wall of the roller 2. The inner retaining ring 16 increases the contact area between the transparent cover 12 and the roller 2, thereby enhancing the stability of the connection between the transparent cover 12 and the roller 2 and preventing the transparent cover 12 from shifting in the radial direction. It also provides a certain sealing effect, reducing the possibility of external impurities entering.

[0038] Further, such as Figure 1and Figure 2 As shown, the outer wall of inner stop ring 16 has a sealing groove and a sealing ring 17 disposed in the sealing groove of inner stop ring 16. Sealing ring 17 further enhances the sealing performance, effectively preventing oil and gas leakage and external impurities from entering the bearing 3 area, providing a clean and sealed working environment for bearing 3 and extending the service life of bearing 3.

[0039] Further, such as Figure 1 and Figure 2 As shown, the outer end of the transparent cover 12 has a protruding outer retaining ring 18, and the retaining ring 14 is mounted on the outer periphery of the outer retaining ring 18. The outer retaining ring 18 provides an accurate installation position for the retaining ring 14, ensuring that the retaining ring 14 can be stably mounted on the outer end of the transparent cover 12. Together with the inner retaining ring 16, it can enhance the stability of the transparent cover 12 from both the inside and the outside, thereby better protecting the bearing 3.
