[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively exclusive of other embodiments.

[0028] Embodiment 1

[0029] As Figure 1 - Figure 5 shown, this is the first embodiment of the present utility model. This embodiment provides a zirconia ceramic structural part, which includes an outer ring 1 of the ceramic part and an inner ring 2 of the ceramic part. The inner cavity of the outer ring 1 of the ceramic part is fixedly installed with the inner ring 2 of the ceramic part. A ceramic cage 3 is fixedly installed between the outer ring 1 of the ceramic part and the inner ring 2 of the ceramic part. The inner cavity of the ceramic cage 3 is fixedly installed with ceramic rolling elements 4. A plurality of heat dissipation holes 5 are opened around the outer wall of the outer ring 1 of the ceramic part, and reinforcing ribs 6 are arranged on both sides of the heat dissipation holes 5.

[0030] As Figure 1 , Figure 2 and Figure 5 shown, the ceramic rolling elements 4 are sequentially installed in the grooves of the ceramic cage 3, and then the whole is placed between the outer ring 1 of the ceramic part and the inner ring 2 of the ceramic part. Heat is generated during the rotation of the outer ring 1 of the ceramic part and the inner ring 2 of the ceramic part. The heat dissipation holes 5 provide a channel for this heat. The heat generated inside the structural part is transferred to the external environment through the heat dissipation holes 5, enabling the structural part to maintain good performance even in a high-temperature environment.

[0031] Embodiment 2

[0032] Refer to Figure 1 , Figure 4And Figure 5 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0033] In this embodiment, the reinforcing ribs 6 are evenly distributed along the outer wall of the outer ring 1 of the ceramic part, there are two groups of heat dissipation holes 5, the outer shape of the heat dissipation holes 5 is funnel-shaped, and the diameter of the heat dissipation holes 5 on the side close to the inner ring 2 of the ceramic part is larger than the diameter of the other side of the heat dissipation holes 5.

[0034] Such as Figure 1 , Figure 4 And Figure 5 As shown, by setting the heat dissipation holes 5 in a funnel shape, not only can the heat inside the structural part be transferred to the external environment, but also the air will accelerate when passing through, so that the heat can be more effectively discharged from the heat dissipation holes 5. In addition, the funnel-shaped design can also reduce the entry of dust and other particulate matters into the interior of the structural part, thereby protecting the internal components and extending the service life of the device.

[0035] Embodiment 3

[0036] Referring to Figure 2 , Figure 3 And Figure 5 , which is the third embodiment of the present utility model, and this embodiment is based on the previous two embodiments.

[0037] In this embodiment, end cap grooves 7 are opened on both the left and right sides of the outer ring 1 of the ceramic part. A number of mounting holes one 8 are respectively opened around the end cap grooves 7. A left end cap 9 is fixedly installed on the left side of the outer ring 1 of the ceramic part, and a right end cap 10 is fixedly installed on the right side of the outer ring 1 of the ceramic part. A number of mounting holes two 11 are opened on the peripheries of the surfaces of the left end cap 9 and the right end cap 10. The positions of the mounting holes one 8 and the mounting holes two 11 correspond to each other. End cap bolts 12 are fixedly installed in the inner cavities of the mounting holes one 8 and the mounting holes two 11. A through hole 13 is opened in the inner cavity of the inner ring 2 of the ceramic part, and a clamping groove 14 is opened on the inner wall of the through hole 13.

[0038] Such as Figure 2 , Figure 3 And Figure 5 As shown, the end caps on both sides can protect the interior of the structural part from the intrusion of external impurities. At the same time, they can also play a sealing role to prevent the leakage of lubricant.

[0039] In use, first connect the inner ring 2 of the ceramic part to other structures through the through holes 13 and the clamping grooves 14. Then, fix the left end cover 9 and the right end cover 10 on both sides of the outer ring 1 of the ceramic part through the end cover bolts 12. Heat is generated during the rotation of the outer ring 1 and the inner ring 2 of the ceramic part. The heat dissipation holes 5 provide a channel for this heat. The heat generated inside the structural part is transferred to the external environment through the heat dissipation holes 5. When the air drives the heat to flow, it will accelerate at the funnel-shaped heat dissipation holes 5, and more efficiently discharge the heat from the inside of the structural part. The reinforcing ribs 6 on the outer ring 1 of the ceramic part can improve the strength and stiffness of the structure, prevent deformation or fracture under external forces, and improve the load-bearing capacity of the structural part.

[0040] In summary: By providing a plurality of heat dissipation holes 5 on the surface of the outer ring 1 of the ceramic part, it can better help the zirconia ceramic structural part dissipate heat during use, increase the contact area between the ceramic part and the surrounding environment, thereby improving the heat dissipation efficiency. The funnel-shaped heat dissipation holes 5 also help to guide the flow of hot air, promote heat convection, further accelerate the heat dissipation speed, reduce heat stress concentration, improve the thermal cycle stability of the structural part, and extend the service life.
