Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a high-efficiency, temperature-resistant bearing. Background Technology

[0002] Bearings are crucial components in modern machinery. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. Simply put, bearings act like the "joints" of machinery, allowing components to rotate smoothly, reducing energy loss and wear, and improving equipment efficiency and lifespan. Based on the shape of the rolling elements, rolling bearings can be broadly classified into ball bearings and roller bearings. Roller bearings can be further categorized by roller shape into cylindrical roller bearings, tapered roller bearings, self-aligning roller bearings, and thrust roller bearings, as well as special-purpose bearings such as magnetic bearings, ceramic bearings, and plastic bearings. These bearings are designed for specific applications and requirements, possessing unique performance and advantages. However, existing bearings suffer from at least the following drawbacks: During operation, the gap between the outer and inner rings allows heat to enter both rings under high temperatures, causing overheating of the rolling elements and leading to bearing deformation and reduced lifespan. Therefore, we have introduced a high-efficiency, high-temperature resistant bearing. Utility Model Content

[0003] The main objective of this invention is to provide a high-efficiency, high-temperature resistant bearing that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-efficiency, high-temperature resistant bearing includes an outer ring, an inner ring disposed within the outer ring, and a plurality of rolling elements disposed between the inner and outer rings. A front protective plate is movably connected to the front end of the outer ring, and a rear protective plate is movably connected to the rear end of the outer ring. Both the rear end of the rear protective plate and the front end of the front protective plate are fixedly connected with a ceramic coating. Four oil injection holes are opened on the outer surface of the outer ring, and the four oil injection holes are evenly distributed.

[0005] Preferably, the front end of the rear protective plate and the rear end of the front protective plate are both fixedly connected with extension rings, and the outer surfaces of the two extension rings are both fixedly connected with clips. The front end of the rear protective plate and the rear end of the front protective plate are both opened with a second through slot.

[0006] Preferably, the diameter of the second slot is larger than the inner diameter of the inner ring.

[0007] Preferably, neither the rear protective plate nor the front protective plate is in contact with the inner ring.

[0008] By adopting the above technical solution, both the rear protective plate and the front protective plate are made of high-temperature resistant materials.

[0009] Preferably, the outer ring has a through slot No. 1, and the front and rear parts of the inner wall of the through slot No. 1 are both provided with arc-shaped grooves.

[0010] Preferably, the card strip engages with the arc-shaped card slot.

[0011] Preferably, neither the extension ring nor the retaining strip contacts the inner ring and the rolling elements.

[0012] This utility model has the following beneficial effects: In this invention, a front protective plate is inserted and connected to the front end of the outer ring, and a rear protective plate is inserted and connected to the rear end of the outer ring. Since both the rear end of the rear protective plate and the front end of the front protective plate are provided with ceramic coatings, and the front protective plate covers the front end of the outer ring while the rear protective plate covers the rear end of the outer ring, the high-temperature resistance of the entire bearing can be improved under the action of the ceramic coating, reducing deformation caused by high temperature. By setting locking strips on the rear and front protective plates and opening an arc-shaped locking groove in the outer ring, the rear and front protective plates are engaged together by the locking strips and the arc-shaped locking groove, making the rear and front protective plates easy to install and improving convenience.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figure 1-4 This utility model provides a technical solution: A high-efficiency, high-temperature resistant bearing includes an outer ring 1, an inner ring 2 inside the outer ring 1, and a plurality of rolling elements 3 arranged between the inner ring 2 and the outer ring 1. A front protective plate 6 is movably connected to the front end of the outer ring 1, and a rear protective plate 4 is movably connected to the rear end of the outer ring 1. Both the rear end of the rear protective plate 4 and the front end of the front protective plate 6 are fixedly connected with ceramic coatings 7. Four oil injection holes 5 are opened on the outer surface of the outer ring 1, and the four oil injection holes 5 are evenly distributed.

[0019] In this embodiment, an extension ring 42 is fixedly connected to the front end of the rear protective plate 4 and the rear end of the front protective plate 6. A retaining strip 41 is fixedly connected to the outer surface of both extension rings 42. A second slot 43 is opened at the front end of the rear protective plate 4 and the rear end of the front protective plate 6, which is through the front and rear. The diameter of the second slot 43 is larger than the inner diameter of the inner ring 2. The rear protective plate 4 and the front protective plate 6 do not contact the inner ring 2. A first slot 12 is opened in the outer ring 1, which is through the front and rear. An arc-shaped retaining groove 11 is opened at the front and rear of the inner wall of the first slot 12. The retaining strip 41 is engaged with the arc-shaped retaining groove 11. The extension ring 42 and the retaining strip 41 do not contact the inner ring 2 and the several rolling elements 3.

[0020] Through the above-described solution, both the rear end of the rear protective plate 4 and the front end of the front protective plate 6 undergo special treatment and are fitted with a high-performance ceramic coating 7. Ceramic coatings are renowned for their excellent high-temperature resistance, maintaining stable physical and chemical properties even at high temperatures. When the bearing is operating at high temperatures, the ceramic coating 7 effectively isolates heat transfer to the bearing's interior, significantly improving the overall high-temperature resistance of the bearing. This greatly reduces bearing component deformation caused by high temperatures, ensuring the bearing maintains precise operating accuracy and stable performance even at high temperatures, extending bearing lifespan, and reducing repair and replacement costs due to high-temperature damage.

[0021] It should be noted that this utility model describes a high-efficiency, high-temperature resistant bearing. At the front end of the outer ring 1, an interlocking connection is cleverly employed to securely install the front protective plate 6. Similarly, at the rear end of the outer ring 1, the same interlocking connection process is used to precisely connect the rear protective plate 4. This design not only enhances the overall integrity of the bearing structure but also lays the foundation for subsequent protective functions. Both the rear end of the rear protective plate 4 and the front end of the front protective plate 6 are specially treated with a high-performance ceramic coating 7. Ceramic coatings are renowned for their excellent high-temperature resistance, maintaining stable physical and chemical properties under high-temperature conditions. When the bearing is operating at high temperatures, the ceramic coating 7 effectively isolates heat transfer to the bearing interior, thereby significantly improving the overall high-temperature resistance of the bearing. This design significantly reduces bearing component deformation caused by high temperatures, ensuring the bearing maintains precise operating accuracy and stable performance even in high-temperature environments. It extends bearing life and reduces repair and replacement costs due to high-temperature damage. Furthermore, for ease of installation, locking strips 41 are meticulously designed on the rear protective plate 4 and front protective plate 6. The dimensions and shapes of these strips are precisely calculated to perfectly match the arc-shaped grooves 11 within the outer ring 1. During installation, simply align the locking strips 41 on the rear and front protective plates 4 and 6 with the arc-shaped grooves 11 within the outer ring 1, and gently push them in for a secure connection. This snap-fit ​​method not only simplifies and speeds up installation, requiring no complex tools or specialized skills and greatly improving installation efficiency, but also ensures a firm connection between the rear protective plate 4 and the front protective plate 6 and the outer ring 1 during subsequent use, preventing loosening and further enhancing the stability and reliability of the bearing structure. By connecting the front and rear protective plates with ceramic coatings to the front and rear ends of the outer ring respectively, and using a snap-fit ​​method with clips and arc-shaped grooves, the high-temperature resistance of the bearing is improved, and the installation process is simplified, providing a strong guarantee for the stable operation of the bearing under various complex working conditions.
