When the oil flows into the inner side of the row hole 32, it will be in contact with the rubber pad 36 under the action of gravity and the support of the partition plate 34, and will push the rubber pad 36 to bend in the direction of the center of the inner wall 10 under the action of gravity, so that one of the rubber pads 36 can drive the embedded pad 38 to move out of the L-shaped groove 37 under the action of external force, so as to open the opening between the two rubber pads 36, so that the oil can flow into the inner side of the ring groove 33 through the row hole 32. When the oil flows back, the rubber pad 36 will bend away from the center of the row hole 32 under the action of external force and the support of the row hole 32, and will be attached to the partition plate 34. At the same time, the embedded pad 38 will be embedded with the L-shaped groove 37, and the elastic properties of the rubber pad 36 and the embedded pad 38 will realize the sealing of the through hole 35, so as to prevent the oil from flowing back to the outside.

[0052] Further, the use method of the nuclear bearing bush is as follows:

[0053] S1, the staff can insert the insertion rod 23 into the inner side of the insertion hole 22 at the corresponding position through the support plate 24 according to the actual needs, then connect the support plate 24 with the fixed plate 6 from the fixed hole 21 with the fixing member, then connect the fixed plate 27 with the fixed hole 8 through the perforated hole 28 with the fixing member, so that the fixed plate 27 can be fixed in the inner side of the gap groove 5 and stably support the top plate 25, then the staff can hang the hook of the hoisting device on the outer side of the U-shaped rod 26, so that the U-shaped rod 26 can be lifted by the top plate 25, the support plate 24, the fixing member and the fixed plate 6 under the action of external force, and then moved to the appropriate position;

[0054] S2, then the staff can use the inner wall 10 to install the upper bush 1 and the lower bush 2 on the working site through the auxiliary bush 9, then connect the fixed hole 8 with the fixing member under the support of the fixed plate 6 and the bottom plate 7 according to the actual needs, so that the upper bush 1 and the lower bush 2 can be connected and fixed at the working site through the screw thread action of the fixed hole 8 and the fixing member;

[0055] S3. Then, the staff needs to add lubricating oil to the inside of the filling port 29 according to the actual needs. The lubricating oil will then flow through the filling port 29 into the inside of the guide groove 30 under the action of gravity, and then flow through the guide groove 30 into the inside of the guide hole 31. Under the guidance of the guide hole 31, it flows into the inside of the drain hole 32, and then flows through the drain hole 32 into the inside of the ring groove 33 to contact the shaft on the inside of the inner shell 10, thereby achieving lubrication of the inside of the inner shell 10.

[0056] S4. Subsequently, the operator needs to hold the sleeve 19 according to the actual situation and push the push ring 17 and push plate 16 to rotate through the push rod 18. Under the action of external force and the support of the support block 13, the push plate 16 drives the threaded rod 14 to rotate around the bearing. At the same time, the sleeve 19 will rotate around the push rod 18 under the action of external force, making it easier to push the push ring 17 to rotate. Meanwhile, the threaded rod 14 will move downward under the action of external force using the thread action with the support block 13. The threaded rod 14 can push the rubber ring 20 downward through the bearing and the bushing 15. Under the action of external force and the support of the support plate 11, the rubber ring 20 squeezes the rubber ring 12. The rubber ring 12 and the rubber ring 20 use their own elasticity to tightly hug the shaft sleeved inside to achieve a sealing effect and prevent lubricating oil leakage.

[0057] Furthermore, it also includes the following steps:

[0058] S31. When lubricating oil flows into the inner side of the drain hole 32, it will pass through the through hole 35 and come into contact with the latex pad 36 under the action of gravity and the support of the partition plate 34. The latex pad 36 will bend towards the center of the inner wall 10 under the action of gravity, so that one of the latex pads 36 can move the fitting pad 38 out of the L groove 37 under the action of external force, thereby opening the opening between the latex pads 36, allowing the lubricating oil to flow into the inner side of the annular groove 33 through the drain hole 32. When there is lubricating oil backflow, the latex pad 36 will bend away from the center of the drain hole 32 under the action of external force and the support of the drain hole 32, and fit against the partition plate 34. At the same time, the fitting pad 38 will fit into the L groove 37, and the elastic properties of the latex pad 36 and the fitting pad 38 will seal the through hole 35, thereby preventing the lubricating oil from flowing back to the outside.

[0059] Working principle: Before using the device, the staff should check whether the device has problems affecting the use. When the staff needs to use the device, the staff should connect the support plate 24 and the fixed plate 27 with the fixed plate 6 and the upper tile 2 according to the actual situation, then use the hooking equipment to hook the U-shaped rod 26 and lift the device to the working place, then put the inner tile 10 on the outside of the shaft, ensure that the upper tile 1 and the lower tile 2 are connected with the positioning hole 3 through the positioning rod 4, fix the fixed plate 6 and the upper tile 2 through the fixed hole 8, finally fill the lubricating oil from the filling port 29, and rotate the threaded rod 14 to prevent leakage.
