All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The present invention relates to a self-aligning roller bearing, comprising an inner bearing ring 1, a cage 2 provided on the outer side of the inner bearing ring 1, eight mounting grooves 3 evenly provided on the front and rear sides of the cage 2, and cylindrical rollers 4 installed inside the mounting grooves 3, with the outer side of the cylindrical rollers 4 in contact with the inner wall of the inner bearing ring 1. A left bearing outer ring 5 and a right bearing outer ring 6 are symmetrically arranged on the outer side of the cage 2, and the outer side of the cylindrical rollers 4 is in contact with the inner walls of the left bearing outer ring 5 and the right bearing outer ring 6. An adjusting connection assembly 7 is installed between the top and bottom ends of the side of the left bearing outer ring 5 and the right bearing outer ring 6 that are close to each other.

[0022] The adjusting connection assembly 7 includes a connecting seat 8, one side of which is fixedly connected to the side of the left bearing outer ring 5 near the right bearing outer ring 6. The top and bottom of the connecting seat 8 are arc-shaped surface structures adapted to the outer and inner walls of the left bearing outer ring 5. A connecting groove 9 is provided inside the end of the connecting seat 8 away from the left bearing outer ring 5. Threaded grooves A10 are symmetrically provided at the top of the connecting groove 9, and these grooves are 180-degree arc-shaped grooves. A strip seat 11 is provided on the side of the connecting seat 8 away from the left bearing outer ring 5, and the side of the strip seat 11 away from the connecting seat 8 is fixedly connected to the side of the right bearing outer ring 6 near the left bearing outer ring 5. The top and bottom of the strip seat 11 are arc-shaped surface structures adapted to the outer and inner walls of the right bearing outer ring 6. A connecting block 12 is fixedly installed on the side of the strip seat 11 away from the outer ring 6 of the right bearing. The top of the connecting block 12 is symmetrically provided with threaded grooves B13, and the threaded grooves B13 are 180-degree arc groove structures. The threads inside the threaded grooves B13 match the threads inside the threaded grooves A10. A connecting screw 14 is threaded between the threaded grooves A10 and B13. A circular end 15 is fixedly installed at one end of the connecting screw 14. A cross-shaped groove 16 is provided on the side of the circular end 15 away from the connecting screw 14. Circular grooves 17 are provided at the top and bottom of the sides of the left bearing outer ring 5 and the right bearing outer ring 6 that are close to each other. The circular end 15 is located inside the circular groove 17. The thickness of the circular end 15 is the same as the depth of the circular groove 17.

[0023] The connecting seat 8 has symmetrically opened positioning grooves 18 on the top side of the side near the strip seat 11. The strip seat 11 has symmetrically fixedly installed positioning blocks 19 on the top side of the side near the connecting seat 8, and the positioning blocks 19 are movably inserted into the inside of the positioning grooves 18. The connecting block 12 has symmetrically opened positioning holes 20 on the side away from the strip seat 11. The inner wall of the connecting groove 9 has symmetrically fixedly installed positioning posts 21, and the positioning posts 21 are movably inserted into the inside of the positioning holes 20.

[0024] During use, the interaction of the inner bearing ring 1, cage 2, mounting groove 3, cylindrical roller 4, left bearing outer ring 5, right bearing outer ring 6, and adjusting connection assembly 7 facilitates the disassembly and assembly of the outer shaft ring of the self-aligning roller bearing, reducing the limitations of its use and thus achieving better practicality. Furthermore, the positioning holes 20 and their interaction enable the connecting block 12 to achieve better positioning within the connecting groove 9, thereby ensuring the stable operation of the adjusting connection assembly 7.

[0025] Working principle: During operation, insert the Phillips screwdriver into the Phillips groove 16 and rotate the round end 15. The round end 15 drives the connecting screw 14 to rotate between the threaded groove A10 and the threaded groove B13. The connecting screw 14 moves while rotating. After the connecting screw 14 moves to disengage from the threaded grooves A10 and B13, pull out the connecting screw 14 to release the fixation between the connecting seat 8 and the connecting block 12. Then, pull the outer ring 6 of the right bearing to move the strip seat 11. The strip seat 11 drives the positioning block 19 to disengage from the positioning groove 18. At the same time, the strip seat 11 drives the connecting block 12 to disengage from the connecting groove 9. The connecting block 12 drives the positioning hole 20 to disengage from the positioning post 21, thus completing the disassembly between the outer ring 5 of the left bearing and the outer ring 6 of the right bearing, thereby completing the disassembly of the outer ring of the self-aligning roller bearing.

[0026] When installing the outer ring of the self-aligning roller bearing, place the left bearing outer ring 5 outside the cage 2, ensuring the inner wall of the left bearing outer ring 5 contacts the outer side of the cylindrical roller 4. Then align the two ends of the right bearing outer ring 6 with the two ends of the left bearing outer ring 5, and insert the connecting block 12 into the connecting groove 9. The connecting block 12 causes the positioning hole 20 to fit onto the outside of the positioning post 21, simultaneously inserting the positioning block 19 into the positioning groove 18. At this point, the thread groove A10 aligns with the thread groove B13. Then... The connecting screw 14 is threaded into the space between the threaded groove A10 and the threaded groove B13 via the circular groove 17, and the connecting screw 14 is tightened. After the circular end 15 is completely moved into the interior of the circular groove 17, the installation between the outer ring 5 of the left bearing and the outer ring 6 of the right bearing is completed, thus completing the installation of the outer shaft ring of the self-aligning roller bearing. This makes it easier to disassemble and assemble the outer shaft ring of the self-aligning roller bearing during use, reducing the limitations of the self-aligning roller bearing in use, and thus achieving better practicality.
