The fixed shaft 5 facilitates the connection of the object to be rotated to the rotating bearing 3, the polygonal embedded block 6 facilitates the clamping of the fixed shaft 5 on the rotating bearing 3, and the mounting rod 7 facilitates the reverse screwing and installation of the fixed shaft 5 into the object to be rotated.

[0026] Further, if Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, the rotating bearing 3 includes a bearing fixed inner core 10, a bearing outer ring 11 sleeved on the outside of the bearing fixed inner core 10, and a number of capsule-shaped ceramic rotors 12 evenly distributed and embedded between the bearing fixed inner core 10 and the bearing outer ring 11. The bearing fixed inner core 10 and the bearing outer ring 11 cooperate with each other to facilitate the rotational embedding and limiting of the number of capsule-shaped ceramic rotors 12, and the number of capsule-shaped ceramic rotors 12 facilitate the rotational connection of the bearing fixed inner core 10 and the bearing outer ring 11 together.

[0027] Further, if Figure 1 、 Figure 2 as well as Figure 4As shown, a number of snap-in grooves 13 adapted to the capsule-shaped ceramic rotor 12 are provided on the side of the bearing fixed inner core 10, and a rolling groove 23 adapted to the capsule-shaped ceramic rotor 12 is provided on the inner ring of the bearing outer ring 11.

Because the capsule-shaped ceramic rotor 12 is similar to a medicine capsule, it can be better snap-in and rotated to the side of the bearing fixed inner core 10 without the need for other structures to fix it.

[0028] Further, if Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, a polygonal embedding groove 22 adapted to the polygonal embedding block 6 is provided on one side of the bearing fixing inner core 10, and a hexagonal screwing groove 14 is provided on the other side of the bearing fixing inner core 10. The bearing fixing inner core 10 is provided with an installation connecting ring 15 on the side close to the polygonal embedding groove 22. The polygonal embedding groove 22 cooperates with the polygonal embedding block 6 to facilitate the insertion of the fixed shaft 5 on the bearing fixing inner core 10. The hexagonal screwing groove 14 facilitates the screwing of the bearing fixing inner core 10 together with the fixed shaft 5 fixed on the bearing fixing inner core 10, so that the mounting rod 7 on the fixed shaft 5 is screwed into the object to be rotated and connected. The installation connecting ring 15 facilitates the screwing and installation of the first screw-on fixing sleeve 8 on the bearing fixing inner core 10.

[0029] Further, if Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, a first screw-on groove 16 is provided on the outer side of the mounting connection ring 15, and a second screw-on groove 17 adapted to the first screw-on groove 16 is provided on the inner wall of the first screw-on fixing sleeve 8. The first screw-on groove 16 and the second screw-on groove 17 are rotatably engaged with each other. The first screw-on groove 16 and the second screw-on groove 17 cooperate with each other to facilitate screwing the first screw-on fixing sleeve 8 onto the mounting connection ring 15.

[0030] Further, if Figure 1 、 Figure 2 、 Figure 5 as well as Figure 6As shown, the first screw-on fixing sleeve 8 is screwed and installed on the mounting connection ring 15, and the fixed shaft 5 is fixedly installed on the bearing fixed inner core 10 by bolts. The inner wall of the second screw-on fixing sleeve 9 is provided with a positive direction screw-on groove 24, and the side of the mounting rod 7 is provided with a reverse direction screw-on groove 25. The positive direction screw-on groove 24 and the reverse direction screw-on groove 25 cooperate with each other so that the end of the fixed shaft 5 provided with the mounting rod 7 can be better fixedly connected to the object to be rotatably connected. Because the screwing directions are opposite, the mounting rod 7 and the second screw-on fixing sleeve 9 will restrain each other and will not loosen.

[0031] Further, if Figure 1 、 Figure 2 as well as Figure 5 As shown, the embedded fixing base 1 includes a first fixed limiting card seat 18 and a second fixed limiting card seat 19 installed below the first fixed limiting card seat 18. The first fixed limiting card seat 18 and the second fixed limiting card seat 19 are fixedly connected by bolts. The first fixed limiting card seat 18 and the second fixed limiting card seat 19 cooperate with each other to facilitate the limited fixed embedding of the rotating bearing 3, which can better fix the high-strength combined bearing structure 2 in the specified position.

[0032] Further, if Figure 1 、 Figure 2 ,as well as Figure 4 As shown, the bearing outer ring 11 is provided with a fixed limit block 20, and the inner walls of the first fixed limit seat 18 and the second fixed limit seat 19 are both provided with a fixed limit groove 21 adapted to the fixed limit block 20. The fixed limit block 20 and the fixed limit groove 21 facilitate the first fixed limit seat 18 and the second fixed limit seat 19 to limit and fix the bearing outer ring 11.

[0033] like Figures 1-6 As shown, the principle of the high-strength combined oil-containing bearing provided in this embodiment is as follows: when using the device, the first fixed limit seat 18 and the second fixed limit seat 19 should be removed first, and then the rotating bearing 3 should be removed. The rotating bearing 3 should then be placed into the first fixed limit seat 18 and the second fixed limit seat 19 and locked with bolts;

[0034] At this time, remove the fixed shaft 5 and insert it into the bearing fixed inner core 10. At this time, make sure that the polygonal insert block 6 is inserted into the polygonal insert groove 22, and then screw the first screw-on fixing sleeve 8 on the mounting connection ring 15, and then fix the bearing fixed inner core 10 and the fixed shaft 5 together with bolts.

[0035] At this time, a tool is inserted into the hexagonal screwing groove 14 to screw the bearing fixing inner core 10 to rotate, and then the rotating bearing fixing inner core 10 will rotate with the fixed shaft 5. At this time, the fixed shaft 5 can be screwed and installed in the object to be rotated and connected under the action of the rotating mounting rod 7. Then, the second screwing fixing sleeve 9 is rotated and installed on the object to be rotated and connected. Because the screwing directions of the second screwing fixing sleeve 9 and the mounting rod 7 are opposite, the mounting rod 7 and the second screwing fixing sleeve 9 will restrain each other and will not loosen. Because the fixed shaft 5 and the rotating bearing 3 have a high concentricity, and the rotor is a capsule-shaped ceramic rotor 12, the device has a high operating strength.
