[0025] The lap ring 401 is placed on the outside of the inner ring 3, and the gasket 7 is overlapped with the inner ring 3. The lap ring 401, the gasket 7 and the inner ring 3 are fixed by screwing the locking rod 9 and the screw hole 13. At this time, the hollow section 402 and the semicircular ring 403 are respectively placed inside the ladder groove 14 and the circular groove 10, and the hollow section 402 and the ladder groove 14 as well as the semicircular ring 403 and the circular groove 10 are all set at a distance, so as to avoid the subsequent contact and friction between the sealing ring 4 and the outer ring 1. At the same time, the tortuous channel generated by this can effectively isolate the external impurities larger than the bulk from directly invading between the outer ring 1 and the inner ring 3, thereby improving the sealing of the bearing structure. At the same time, the locking rod 9 is used to fix the lap ring 401 and the inner ring 3. On the one hand, the convenience of the overall assembly of the bearing structure is ensured, and at the same time, the sealing ring 4 can be conveniently separated later to clean and maintain the inside of the bearing structure or the tortuous channel.

[0026] Specifically, Figure 2 and Figure 4 As shown, the outer wall of the arcuate end of the outer ring 1 is fixedly connected with multiple groups of mounting plates 2 6, the outer wall of the horizontal end of the inner ring 3 is fixedly connected with multiple groups of mounting plates 1 5, and the inner walls of the multiple groups of mounting plates 1 5 are all screwed together with mounting rods 12, which are used to connect the bearing structure with the external receiving part, and the inner wall of the lap ring 401 is screwed together with a locking rod 9, which is fixedly connected to the inner ring 3 through a screw hole 13, and multiple groups of locking rods 9 and screw holes 13 are provided, and the multiple groups of locking rods 9 and screw holes 13 are distributed in a ring shape, which ensures the convenience of the overall assembly of the bearing structure.

At the same time, the tortuous channel generated by this can effectively isolate the external impurities larger than the bulk from directly invading between the outer ring 1 and the inner ring 3, thereby improving the sealing performance of the bearing structure. The locking rod 9 is used to fix the loop 401 and the inner ring 3, which ensures the convenience of the overall assembly of the bearing structure. At the same time, the sealing ring 4 can be easily separated later to clean and maintain the inside of the bearing structure or the tortuous channel. After the loop 401 and the inner ring 3 are fixed by the locking rod 9, the rubber pad 8 can be inserted into the loop 401. The interference fit ensures the stability of the position of the rubber pad 8 itself. On the one hand, the rubber pad 8 can isolate the locking rod 9 to reduce the risk of rust. On the other hand, it can also limit the loosening of the locking rod 9 by friction, thereby improving the stability of the high-sealing bearing structure.
