Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a metallurgical bearing based on high-carbon steel forgings. Background Technology

[0002] In the metallurgical industry, bearings are key components of metallurgical equipment, playing a vital role in supporting rotating parts and transmitting power. Metallurgical processes are typically accompanied by harsh conditions such as high temperatures, high loads, high dust levels, and significant impacts, which place extremely high demands on bearing performance.

[0003] Currently, traditional metallurgical bearings, when made of ordinary steel, often lack sufficient hardness, wear resistance, and high-temperature resistance. Under the long-term influence of heavy loads, high-speed rotation, and high-temperature environments in metallurgical equipment, they are prone to premature wear, deformation, and even failure. In terms of structural design, many traditional bearings have poor sealing performance, allowing dust, metal shavings, and other impurities from the metallurgical environment to easily penetrate the bearing interior, exacerbating wear between the rolling elements and the inner and outer rings. Simultaneously, the wear-resistant structural design of traditional bearings is inadequate, lacking effective wear-resistant components to cope with continuous friction. This results in a short bearing lifespan, and frequent replacements not only increase production costs for metallurgical enterprises but also affect production efficiency due to equipment downtime. Utility Model Content

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a metallurgical bearing based on high carbon steel forging, comprising: a bearing housing assembly, an outer ring fixedly installed on the outer surface of the bearing housing assembly, a washer fixedly installed inside the bearing housing assembly, a rolling element rotatably installed at the axial center of the bearing housing assembly, and a wear-resistant component sleeved on the outer surface of the rolling element;

[0005] The bearing housing assembly includes a bearing seat, a bearing cover fixedly mounted on the surface of the bearing seat, an outer ring on the surface of the bearing cover, a through hole inside the bearing cover, and a gasket fixedly mounted on the inner wall of the bearing seat. The bearing cover, through the through hole and other structures, mates with the bearing seat, encapsulating and protecting the internal rolling elements and wear-resistant components, preventing the intrusion of harmful media from the metallurgical environment, and protecting the internal parts. Simultaneously, the gasket and washer provide buffering and sealing between the bearing cover and the bearing seat, and between the gasket and the adjacent surfaces of the bearing cover, reducing the entry of dust and impurities from the external metallurgical environment into the bearing, and mitigating impacts between components. An outer ring fixed to the outer surface of the bearing housing assembly further enhances the structural stability of the bearing housing assembly, enabling it to better withstand external forces during the metallurgical process.

[0006] Preferably, the bearing housing is fixedly connected to the metallurgical equipment, the outer ring is disposed on the outer surface of the rolling element and is rotatably adapted to the rolling element, and the washer is disposed between the adjacent surfaces of the washer and the bearing cap.

[0007] Preferably, the rolling element includes a shaft, a collar is fixedly installed on the side of the outer surface of the shaft, and an inner ring is formed on the surface of the shaft near the collar. Balls are rotatably mounted on the surface of the inner ring. During the metallurgical process, the bearing housing is fixedly connected to the metallurgical equipment, providing a stable mounting foundation for the entire bearing, ensuring the bearing is fixed in position on the metallurgical equipment and can withstand various external forces during metallurgical operations. The shaft, as the core component of the rolling element, begins to rotate under the power transmission of the metallurgical equipment. When the shaft rotates, the balls on its outer surface roll between the inner ring of the shaft and the outer ring of the bearing cap, converting sliding friction into rolling friction, greatly reducing frictional resistance, allowing the shaft to rotate more smoothly, while reducing wear between components and improving the transmission efficiency and durability of the bearing. The collar acts as a limiter for the balls and other components, ensuring that the balls roll within a designated area and maintaining the normal operating order of the bearing.

[0008] Preferably, the ball is rotatably adapted to the outer ring via a shaft, the shaft extending through the wear-resistant component into its cavity.

[0009] Preferably, the wear-resistant component includes a sleeve shaft, the outer surface of which is fitted with an isolation cover. A locking block is fixedly installed on the inner wall of the isolation cover. Several locking blocks are provided, and each locking block has a wear-resistant block fitted on its surface. A reinforcing pad is fixedly installed on the surface of each wear-resistant block. The wear-resistant component is fitted onto the outer surface of the shaft. As the shaft rotates, the isolation cover, sleeve shaft, etc., also rotate. With the locking blocks fixed in place, the wear-resistant blocks, together with the reinforcing pads, continuously withstand friction with the isolation cover, sleeve shaft, and other components. The wear-resistant blocks and reinforcing pads can withstand long-term friction, effectively resisting the large amount of friction generated by rotation during the metallurgical process, protecting the sleeve shaft, isolation cover, and other components, significantly extending the overall service life of the bearing, and reducing equipment downtime and maintenance frequency due to bearing wear.

[0010] Preferably, the sleeve is fitted onto the outer surface of the shaft, the snap-fit ​​block is fixedly connected to the outer surface of the sleeve, and the wear-resistant block and reinforcing pad are disposed between the isolation cover and the opposite surfaces of the sleeve.

[0011] This invention provides a metallurgical bearing based on a high-carbon steel forging. It has the following advantages:

[0012] (I) This metallurgical bearing based on high-carbon steel forgings provides a stable mounting foundation for the entire bearing by fixing the bearing housing to the metallurgical equipment during the metallurgical process. This ensures the bearing is fixed in position on the metallurgical equipment and can withstand various external forces during metallurgical operations. The shaft, as the core component of the rolling elements, begins to rotate under the power transmission of the metallurgical equipment. When the shaft rotates, the balls on its outer surface roll between the inner ring of the shaft and the outer ring of the bearing cap, converting sliding friction into rolling friction. This greatly reduces frictional resistance, allowing the shaft to rotate more smoothly, while also reducing wear between components and improving the bearing's transmission efficiency and durability. The bearing collar acts as a limiter for the balls and other components, ensuring that the balls roll within a designated area and maintaining the normal operating order of the bearing.

[0013] (II) This metallurgical bearing based on high-carbon steel forgings, through a bearing cap and through-holes, mates with the bearing housing, encapsulating and protecting the internal rolling elements and wear-resistant components. This prevents harmful media from the metallurgical environment from entering and protects the internal parts. Simultaneously, washers and gaskets between the bearing cap and bearing housing, and between the gasket and the adjacent surfaces of the bearing cap, provide buffering and sealing, reducing the entry of dust and impurities from the external metallurgical environment into the bearing and mitigating impacts between components. An outer ring fixed to the outer surface of the bearing housing further enhances the structural stability of the bearing housing assembly, enabling it to better withstand external forces during the metallurgical process.

[0014] (III) This metallurgical bearing based on high-carbon steel forgings is fitted onto the outer surface of the shaft via wear-resistant components. As the shaft rotates, the isolation cover, sleeve shaft, etc., also rotate. With the fixing of the snap-fit ​​block, the wear-resistant block, together with the reinforcing pad, continuously withstands friction with the isolation cover, sleeve shaft, and other components. The wear-resistant block and reinforcing pad can withstand long-term friction, effectively resisting the large amount of friction generated by rotation during the metallurgical process, protecting the sleeve shaft, isolation cover, and other components, significantly extending the overall service life of the bearing, and reducing equipment downtime and maintenance frequency due to bearing wear.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] First embodiment, such as Figures 1 to 5 As shown, this utility model provides a technical solution: a metallurgical bearing based on high carbon steel forgings, comprising: a bearing housing assembly 2, an outer ring 1 fixedly installed on the outer surface of the bearing housing assembly 2, a washer 4 fixedly installed inside the bearing housing assembly 2, a rolling element 3 rotatably installed at the axis of the bearing housing assembly 2, and a wear-resistant component 5 sleeved on the outer surface of the rolling element 3.

[0023] The bearing housing assembly 2 includes a bearing seat 21, on which a bearing cover 22 is fixedly mounted. The bearing cover 22 has an outer ring 25 on its surface and a through hole 23 inside. A gasket 24 is fixedly mounted on the inner wall of the bearing seat 21. The bearing cover 22, through the through hole 23 and other structures, cooperates with the bearing seat 21 to encapsulate and protect the internal rolling elements 3 and wear-resistant components 5, preventing the intrusion of harmful media from the metallurgical environment and protecting the internal parts. Simultaneously, the gasket 4 and gasket 24, between the adjacent surfaces of the bearing cover 22 and the bearing seat 21, and between the gasket 24 and the bearing cover 22, provide buffering and sealing effects, reducing the entry of dust and impurities from the external metallurgical environment into the bearing and mitigating impacts between components. An outer ring 1 is fixed to the outer surface of the bearing housing assembly 2, further enhancing the structural stability of the bearing housing assembly 2 and enabling it to better withstand external forces during the metallurgical process.

[0024] The bearing housing 21 is fixedly connected to the metallurgical equipment. The outer ring 25 is disposed on the outer surface of the rolling element 3 and is rotatably adapted to the rolling element 3. The washer 4 is disposed between the adjacent surfaces of the washer 24 and the bearing cover 22.

[0025] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 2 , Figure 3 and Figure 5As shown, the rolling element 3 includes a shaft 33, with a collar 31 fixedly installed on the side of the outer surface of the shaft 33. An inner ring 34 is formed on the surface of the shaft 33 near the collar 31, and balls 32 are rotatably mounted on the surface of the inner ring 34. During the metallurgical process, the bearing housing 21 is fixedly connected to the metallurgical equipment, providing a stable mounting base for the entire bearing, ensuring the bearing is fixed in position on the metallurgical equipment and can withstand various external forces during metallurgical operations. The shaft 33, as the core component of the rolling element 3, begins to rotate under the power transmission of the metallurgical equipment. When the shaft 33 rotates, the balls 32 on its outer surface roll between the inner ring 34 of the shaft 33 and the outer ring 25 of the bearing cover 22, converting sliding friction into rolling friction, greatly reducing frictional resistance, allowing the shaft 33 to rotate more smoothly, while reducing wear between components and improving the transmission efficiency and durability of the bearing. The collar 31 acts as a limiter for the balls 32 and other components, ensuring that the balls 32 roll within a designated area and maintaining the normal operating order of the bearing.

[0026] The ball bearing 32 is rotatably adapted to the outer ring 25 via the shaft 33, which extends through the wear-resistant component 5 into its cavity.

[0027] The wear-resistant component 5 includes a sleeve shaft 52, with an isolation cover 51 fitted on the outer surface of the sleeve shaft 52. A locking block 53 is fixedly installed on the inner wall of the isolation cover 51. Several locking blocks 53 are provided, and each locking block 53 has a wear-resistant block 55 fitted on its surface. A reinforcing pad 54 is fixedly installed on the surface of each wear-resistant block 55. The wear-resistant component 5 is fitted onto the outer surface of the shaft 33. As the shaft 33 rotates, the isolation cover 51, sleeve shaft 52, etc., also rotate. With the locking blocks 53 fixed in place, the wear-resistant blocks 55, together with the reinforcing pads 54, continuously withstand friction with the isolation cover 51, sleeve shaft 52, and other components. The wear-resistant blocks 55 and reinforcing pads 54 can withstand long-term friction, effectively resisting the large amount of friction generated by rotation during the metallurgical process, protecting the sleeve shaft 52, isolation cover 51, and other components, significantly extending the overall service life of the bearing, and reducing equipment downtime and maintenance frequency due to bearing wear.

[0028] The sleeve 52 is sleeved on the outer surface of the shaft 33, the snap-fit ​​block 53 is fixedly connected to the outer surface of the sleeve 52, and the wear-resistant block 55 and the reinforcing pad 54 are disposed between the isolation cover 51 and the opposite surface of the sleeve 52.

[0029] During use, in the metallurgical process, the bearing housing 21 is fixedly connected to the metallurgical equipment, providing a stable mounting foundation for the entire bearing and ensuring that the bearing is fixed in position on the metallurgical equipment and can withstand various external forces during metallurgical operations. The shaft 33, as the core component of the rolling element 3, begins to rotate under the power transmission of the metallurgical equipment. When the shaft 33 rotates, the balls 32 on its outer surface roll between the inner ring 34 of the shaft 33 and the outer ring 25 of the bearing cover 22, converting sliding friction into rolling friction, greatly reducing frictional resistance, allowing the shaft 33 to rotate more smoothly, while reducing wear between components and improving the transmission efficiency and durability of the bearing. The collar 31 acts as a limiter for the balls 32 and other components, ensuring that the balls 32 roll within a designated area and maintaining the normal operating order of the bearing.

[0030] The bearing cap 22, through structures such as the through hole 23, mates with the bearing housing 21, encapsulating and protecting the internal rolling elements 3 and wear-resistant components 5, preventing the intrusion of harmful media from the metallurgical environment and protecting the internal parts. Simultaneously, the gasket 4 and shim 24, located between the bearing cap 22 and the bearing housing 21, and between the shim 24 and the adjacent surfaces of the bearing cap 22, provide buffering and sealing effects, reducing the entry of dust and impurities from the external metallurgical environment into the bearing and mitigating impacts between components. The outer ring 1, fixed to the outer surface of the bearing housing assembly 2, further enhances the structural stability of the bearing housing assembly 2, enabling it to better withstand external forces during the metallurgical process.

[0031] Wear-resistant component 5 is sleeved on the outer surface of shaft 33. As shaft 33 rotates, isolation cover 51, sleeve shaft 52, etc. also rotate. Under the fixation of snap-fit ​​block 53, wear-resistant block 55 works together with reinforcing pad 54 to continuously withstand friction with components such as isolation cover 51 and sleeve shaft 52. Wear-resistant block 55 and reinforcing pad 54 can withstand long-term friction, effectively resisting the large amount of friction generated by rotation during metallurgical process, protecting components such as sleeve shaft 52 and isolation cover 51, significantly extending the overall service life of bearings, and reducing the number of equipment downtimes and maintenance caused by bearing wear.
