[0025] Embodiment 1: A fitting device for a bearing end cover, such as Figure 1-Figure 2 As shown, it includes a bearing body 1, and an inner end cover 3 and an outer end cover 2 slidably arranged on both sides of the bearing body 1, a device box 8 is arranged on one side of the inner end cover 3 and the outer end cover 2, and a movable plate 16 is arranged on both sides of the device box 8, and a clamp 18 is fixedly installed on one side of the movable plate 16. After the staff slides the outer end cover 2 and the inner end cover 3 to the bearing body 1, they are placed between the clamps 18, and the two movable plates 16 are moved by the set driving device. By setting the movable plate 16 and the clamp 18 to be fixedly connected, the clamp 18 is driven to move, so that the connection between the outer end cover 2 and the inner end cover 3 and the bearing body 1 can be tighter, and then the set fastening device is connected thereto, so as to avoid the problem that the end cover and the bearing are not tightly fitted due to insufficient operating force of the staff, thereby causing poor sealing.

[0026] like Figure 1-Figure 2As shown, a driving device 9 is fixedly installed at one end of the device box 8, and a rotating shaft 10 is fixedly installed at the output end of the driving device 9. The rotating shaft 10 extends into the device box 8, and a driving tooth 11 is fixedly installed at one end of the rotating shaft 10 away from the driving device 9. The driving tooth 11 is meshingly connected with a driven tooth 12, and a connecting rod 13 is fixedly installed on the driven tooth 12. By setting the driving device 9, and the rotating shaft 10 is fixedly installed at the output end of the driving device 9, and the driving tooth 11 is fixedly installed on the rotating shaft 10, when the staff turns on the driving device 9, the rotating shaft 10 is rotated, thereby driving the driving tooth 11 to rotate, and by setting the driving tooth 11 to mesh with the driven tooth 12, when the driving tooth 11 rotates, the driven tooth 12 is driven to rotate, and by setting the driven tooth 12 to be fixedly connected with the connecting rod 13, when the driven tooth 12 rotates, the connecting rod 13 is driven to rotate.

[0027] Embodiment 2: A fitting device for a bearing end cover, such as Figure 1-Figure 2 As shown, a No. 1 threaded rod 14 is fixedly installed at one end of the connecting rod 13, and a No. 2 threaded rod 15 is fixedly installed at the end of the connecting rod 13 away from the No. 1 threaded rod 14. The No. 1 threaded rod 14 and the No. 2 threaded rod 15 are both threadedly connected with the movable plate 16, and a guide rod 17 is slidably arranged on the movable plate 16. By fixing the No. 1 threaded rod 14 and the No. 2 threaded rod 15 at both ends of the connecting rod 13, and the thread directions of the No. 1 threaded rod 14 and the No. 2 threaded rod 15 are opposite, and at the same time, the No. 1 threaded rod 14 and the No. 2 threaded rod 15 are both threadedly connected with the movable plate 16. The threaded connection allows the connecting rod 13 to rotate, thereby driving the No. 1 threaded rod 14 and the No. 2 threaded rod 15 to rotate, so that the movable plate 16 moves toward or away from each other, thereby driving the clamp 18 to move, thereby making the connection between the bearing body 1, the outer end cover 2 and the inner end cover 3 tighter, thereby achieving a better sealing effect. A guide rod 17 is provided, and the guide rod 17 passes through the device box 8 and extends to the outside of the movable plate 16 at the other end, so that the movable plate 16 can move more smoothly.

[0028] like Figure 1-Figure 4As shown, threaded connection holes 4 are provided on the outer end cover 2 and the inner end cover 3. A protruding block 7 is fixedly installed on one end of the outer end cover 2 close to the bearing body 1. A sealing strip 6 is fixedly installed on the outer side of the protruding block 7. A mounting groove 5 is provided on one end of the inner end cover 3 close to the bearing body 1. A bolt 19 is threadedly connected to the threaded connection hole 4. A nut 20 is threadedly screwed on one end of the bolt 19. The staff inserts the protruding block 7 through the bearing body 1 and fits it into the mounting groove 5. Then, the bearing body 1, the outer end cover 2 and the inner end cover 3 are placed between the clamps 18. By setting the sealing strip 6, which has a certain elastic force, when the clamp 18 moves relatively, It can make the connection between the outer end cover 2 and the inner end cover 3 tighter, and thus the connection between the outer end cover 2 and the bearing body 1 tighter. At this time, the staff will threadably engage the bolt 19 with the threaded connection hole 4 on the outer end cover 2, and the bolt 19 will extend to the outside of the inner end cover 3. The staff will screw the nut 20 on the end of the bolt 19 close to the inner end cover 3, so that the nut 20 and the bolt 19 are threadably engaged, thereby making the connection between the outer end cover 2, the inner end cover 3 and the bearing body 1 tighter and making the sealing better. When the nut 20 is installed, the staff will take it away from the clamp 18.

[0029] Working principle: After the staff slide the outer end cover 2 and the inner end cover 3 to the bearing body 1, they are placed between the clamps 18. The two movable plates 16 are moved by the driving device. The movable plates 16 are fixedly connected to the clamps 18, thereby driving the clamps 18 to move. The outer end cover 2 and the inner end cover 3 can be more tightly connected to the bearing body 1. Then, the fastening device is connected to them, which avoids the problem that the end cover and the bearing are not tightly fitted due to insufficient operating force of the staff, thereby causing poor sealing. A No. 1 threaded rod 14 and a No. 2 threaded rod 15 are fixedly installed at both ends of the connecting rod 13, and the thread directions of the No. 1 threaded rod 14 and the No. 2 threaded rod 15 are opposite. At the same time, the No. 1 threaded rod 14 and the No. 2 threaded rod 15 are threadedly connected with the movable plate 16, so that when the connecting rod 13 rotates, the No. 1 threaded rod 14 and the No. 2 threaded rod 15 are driven to rotate, so that the movable plate 16 moves toward or away from each other, thereby driving the clamp 18 to move, so that the connection between the bearing body 1, the outer end cover 2 and the inner end cover 3 is tighter, so that the sealing effect is better.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
