A number of balls 3 are rollingly assembled between the two concave circular grooves;

[0030] It further includes: a cover component for preventing foreign objects from entering between the inner ring 1 of the bearing and the outer ring 2 of the bearing. The cover component is located on the top of the outer ring 2 of the bearing;

[0031] A bottom support component for protecting the bottom of the inner ring 1 of the bearing and the outer ring 2 of the bearing. The bottom support component is located at the bottom of the inner ring 1 of the bearing;

[0032] Auxiliary adhesion component, used to improve the connection strength between the inner ring 1 of the bearing and the outer ring 2 of the bearing and the ceramic.

[0033] The outer ring 2 of the bearing and the inner ring 1 of the bearing are distributed in a staggered up-and-down manner. A cage 4 is also slidably assembled between the inner ring 1 of the bearing and the outer ring 2 of the bearing. The cage 4 is used to evenly distribute a number of balls 3 in a circumferential equidistant manner, avoiding wear between the inner ring 1 of the bearing and the cover plate 5, and between the outer ring 2 of the bearing and the lower support plate 8 during the use of the bearing assembly. The cage 4 can evenly distribute the balls 3 between the inner ring 1 of the bearing and the outer ring 2 of the bearing.

[0034] The cover component includes a cover plate 5 fixedly covering the central hole at the upper end of the outer ring 2 of the bearing. The upper end face of the inner ring 1 of the bearing does not contact the lower end face of the cover plate 5. The function of the cover plate 5 is to prevent foreign impurities or glue from entering between the inner ring 1 of the bearing and the outer ring 2 of the bearing when the bearing assembly is combined and assembled with the ceramic.

[0035] The lower end face of the inner ring 1 of the bearing is fixedly provided with a lower support plate 8, and the upper end face of the lower support plate 8 does not contact the lower end face of the outer ring 2 of the bearing. The lower support plate 8 also serves to prevent the ceramic material from directly contacting the bearing assembly.

[0036] The auxiliary adhesion component includes fastening parts 7 distributed on the lower end face of the lower support plate 8, the outer side wall of the lower support plate 8, the upper end face of the outer ring 2 of the bearing, and the outer side wall of the outer ring 2 of the bearing.

The design of the through hole 6 facilitates ventilation during adhesive fixation and avoids the accumulation of air bubbles.

[0039] The outer diameter of the lower support plate 8 is the same as the outer diameter of the outer ring 2 of the bearing.

[0040] Working principle:

[0041] When the user makes the lid of the gaiwan using the bearing assembly described in this solution, first, the lid, the upper lid that can rotate later, and the sculpture are shaped from clay. After firing and forming, first, the lower support plate 8 of the bearing assembly is bonded to the bottom center of the lid base. The bonding is done through AB glue. The AB glue mixed in a certain proportion is coated on the bottom and its outer periphery of the lower support plate 8. The AB glue is pressed by a coating tool so that the AB glue can fill the buckle grooves distributed on the lower support plate 8. Finally, the lower support plate 8 is pressed on the upper center of the lid's upper lid, and the bottom of the lower support plate 8 and the lid's upper lid are adhered together by the glue.

[0042] Then, the sculpture is bonded to the top of the bearing outer ring 2. AB glue is coated on the bottom surface of the sculpture, the upper end of the bearing outer ring 2, and the upper end of the cover plate 5, and the AB glue can fill the inside of the buckle grooves distributed on the bearing outer ring 2. The bottom surface of the sculpture, the bearing outer ring 2, and the upper end surface of the cover plate 5 are bonded together through the AB glue.

[0043] After completing the above assembly, wait for the AB glue to completely cure. After curing, a finished product, a rotatable lid, can be obtained. The manufacturing method in this solution compared with the prior art: The ceramic is more firmly connected to the bearing outer ring 2 and the bearing inner ring 1, and the yield rate is higher. It can effectively avoid the situation that the teacup lid and the sculpture are skewed and wobbled after the AB glue cures.

[0044] Embodiment 2: This embodiment is another implementation manner of Embodiment 1. The fastening part 7 is a buckle convex ring. The buckle convex ring is in the shape of a cone or a cylindrical ring, and several slot holes are provided on the outer surface of the buckle convex ring.

[0045] In this embodiment: The protruding buckle convex ring is assembled in a wrapped manner through AB glue. When the glue cures, the ceramic will wrap the buckle convex ring inside, and the design of the slot holes can allow the glue to enter. When the glue cures, a small part of the glue will be trapped in the slot holes, thereby further improving the fastening between the ceramic and the bearing assembly.
