Description

Technical Field

[0001] This utility model belongs to the field of steel roller technology, and specifically relates to a high-load-bearing heat-resistant steel roller with stable rotation. Background Technology

[0002] During use, steel rollers may experience centrifugal force unevenness due to material inhomogeneity, manufacturing defects, or uneven wear, causing a shift in their center of gravity during rotation. This unevenness can trigger vibration, reduce operational stability, and even damage connected mechanical components. Simultaneously, bearings are prone to wear and aging under prolonged rotational loads, leading to increased clearance and reduced support accuracy of the steel roller, further exacerbating vibration. Insufficient installation accuracy is often caused by environmental factors, improper installation processes, or a lack of necessary alignment tools, resulting in lateral deviations during rotation and unstable operation.

[0003] Traditional solutions to these problems include regular inspection and maintenance, replacing worn bearings, and improving accuracy by adjusting the mounting angle. However, these methods have drawbacks: regular maintenance and bearing replacement are costly, especially in large production lines where prolonged downtime leads to decreased production efficiency. Furthermore, while adjusting the mounting can improve stability to some extent, it does not fundamentally solve the problem of unevenness in the manufacturing process. Relying on these traditional methods in the long term is insufficient to completely resolve the issue of smoothness in steel roll rotation. Therefore, we aim to design a steel roll with a novel structure to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-load-bearing heat-resistant steel roller with smooth rotation, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a high load-bearing heat-resistant steel roller with stable rotation, comprising: a steel roller assembly and a roller body, wherein an outer sleeve for supporting materials is installed on the outside of the steel roller assembly, and a leveling component for adjusting the rotational balance of the entire steel roller is installed on the steel roller assembly.

[0006] The leveling assembly includes a central shaft for fixing and screws for leveling. Multiple screws for leveling are welded to the outer wall of the central shaft, and each screw is threaded with an anti-loosening nut.

[0007] In a preferred embodiment, the steel roller assembly includes a water conveying shaft for connection with an external rotary joint. The inner end of the water conveying shaft is provided with a fixing plate 1 and a fixing plate 2. The fixing plate 1 is located outside the fixing plate 2 and is used to fixally connect with the fixing plate 3 at the end of the outer sleeve.

[0008] In a preferred embodiment, the left and right ends of the outer sleeve are respectively provided with a boss in the shape of a ring. The left and right sides of the outer sleeve are respectively fixed with a fixing plate three through a boss. The inner diameter of the boss is larger than the diameter of fixing plate one and fixing plate two. Fixing plate one and fixing plate two can fix the water conveying shaft and can also be connected to the roller body to ensure the stability of the entire device.

[0009] In a preferred embodiment, an end plate is provided at the left and right ends of the roller body, and the diameter of the end plate is larger than the diameter of the second fixed plate. The end plate is sealed and fixedly connected to the second fixed plate. The water conveying shaft is provided with a connecting hole radially inward at the part between the first fixed plate and the second fixed plate. The connecting hole allows the cooling water between the first fixed plate and the second fixed plate to be connected to the external rotary joint through the water conveying shaft, thereby enabling water supply and drainage to the outside of the roller body.

[0010] In a preferred embodiment, the edges of the end plates on both sides extend away from the roller body to form multiple equally spaced relief grooves. The relief grooves are connected to the space between the first fixed plate and the second fixed plate. The relief grooves allow the cooling water on the outside of the roller body to be connected to the space between the first fixed plate and the second fixed plate.

[0011] In a preferred embodiment, the outer wall of the roller is spirally welded with spiral blades for guiding water, and the height of the upper end of the spiral blades is flush with the height of the upper side of the end plate.

[0012] In a preferred embodiment, the roller body has an installation cavity inside, and a central shaft is fixed inside the roller body through the installation cavity. The two ends of the central shaft are respectively inserted and abutted against the inner end of a water conveying shaft.

[0013] In a preferred embodiment, the screw is provided in multiple sets, and each set is provided with three screws arranged in three equal parts. The outer wall of the screw is provided with an external thread that matches the anti-loosening nut.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are: 1. By setting an outer sleeve and a steel roller body, and welding spiral blades on the outer wall of the roller body, the cooling water moves around the outer wall of the roller body according to the spiral structure of the spiral blades, thereby cooling the outer sleeve and the steel roller assembly, which helps to ensure the cooling performance of the steel roller assembly. Furthermore, since the height of the upper end of the spiral blades is flush with the height of the upper side of the end plate, the spiral blades can support the outer sleeve, thereby ensuring the load-bearing capacity of the outer sleeve.

[0015] 2. By setting up a leveling component, if the roller body deflects during rotation, the degree of deflection determines which side of the roller body has a stronger circumferential centrifugal force. Then, remove the fixing plate three and take out the leveling component installed inside the roller body. Then, adjust the position of the anti-loosening nut on the screw, that is, the distance close to the central shaft, thereby adjusting the stability of the centrifugal force when the entire roller body rotates, so that the roller body is more stable when rotating.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a high load-bearing heat-resistant steel roller with stable rotation, including: a steel roller assembly 200 and a roller body 250. An outer sleeve 100 for supporting materials is installed on the outside of the steel roller assembly 200, and a leveling component 300 for adjusting the rotational balance of the entire steel roller is installed on the steel roller assembly 200.

[0026] The leveling assembly 300 includes a central shaft 310 for fixing and screws 320 for leveling. Multiple screws 320 for leveling are welded to the outer wall of the central shaft 310, and each screw 320 is threaded with an anti-loosening nut 330.

[0027] Please see Figures 1 to 3 The steel roller assembly 200 includes a water conveying shaft 210 for connection with an external rotary joint. The inner end of the water conveying shaft 210 is provided with a fixing plate 220 and a fixing plate 2. The fixing plate 220 is located outside the fixing plate 2 and is used to fix the fixing plate 3 at the end of the outer sleeve 100.

[0028] The left and right ends of the outer sleeve 100 are respectively provided with a ring-shaped boss. The left and right sides of the outer sleeve 100 are respectively fixed with a fixing plate 3 through a boss. The inner diameter of the boss is larger than the diameter of fixing plate 1 220 and fixing plate 2. Fixing plate 1 220 and fixing plate 2 can fix the water conveying shaft 210 and can also be connected to the roller body 250 to ensure the stability of the entire device.

[0029] The left and right ends of the roller body 250 are respectively provided with an end plate 230. The diameter of the end plate 230 is larger than the diameter of the second fixed plate. The end plate 230 is sealed and fixedly connected to the second fixed plate. The water conveying shaft 210 located between the first fixed plate 220 and the second fixed plate has a connecting hole radially inward. The connecting hole allows the cooling water between the first fixed plate 220 and the second fixed plate to be connected to the external rotary joint through the water conveying shaft 210, thereby enabling water supply and drainage to the outside of the roller body 250.

[0030] The edges of the end plates 230 on both sides extend away from the roller body 250 to form multiple equally spaced relief grooves 231. The relief grooves 231 are connected to the space between the first fixed plate 220 and the second fixed plate. The setting of the relief grooves 231 allows the cooling water on the outside of the roller body 250 to be connected to the space between the first fixed plate 220 and the second fixed plate.

[0031] The outer wall of the roller body 250 is spirally welded with spiral blades 240 for guiding water. The height of the upper end of the spiral blades 240 is flush with the height of the upper side of the end plate 230.

[0032] As the first embodiment of this utility model, in actual use, cooling water is transported to the space between the first fixed plate 220 and the second fixed plate through the water conveying shaft 210 on one side of the roller body 250, and then enters the space between the outer sleeve 100 and the outer wall of the roller body 250 through the relief groove 231 on the end plate 230. The outer wall of the roller body 250 is welded with spiral blades 240, so that the cooling water moves around the outer wall of the roller body 250 according to the spiral structure of the spiral blades 240, thereby cooling the outer sleeve 100 and the steel roller assembly 200, which helps to ensure the cooling performance of the steel roller assembly 200. Since the height of the upper end of the spiral blades 240 is flush with the height of the upper side of the end plate 230, the spiral blades 240 can support the outer sleeve 100, thereby ensuring the load-bearing capacity of the outer sleeve 100.

[0033] Please see Figure 4 The roller body 250 has an installation cavity inside, and a central shaft 310 is fixed inside the roller body 250 through the installation cavity. The two ends of the central shaft 310 are respectively inserted and abutted to the inner end of a water conveying shaft 210.

[0034] The screw 320 is provided in multiple sets, and each set is provided with three screws 320 arranged in three equal parts. The outer wall of the screw 320 is provided with external threads that match the anti-loosening nut 330.

[0035] As a second embodiment of this utility model, in actual use, since there are multiple sets of screws 320, and each set has three screws 320 arranged in three equal parts, the outer wall of the screws 320 is provided with external threads that match the anti-loosening nuts 330. If the roller body 250 deflects when rotating, the degree of deflection determines which side of the roller body 250 has a stronger circumferential centrifugal force. Then, the fixing plate three is removed, and the leveling component 300 installed inside the roller body 250 is taken out (if it is not taken out, first mark which side of the anti-loosening nuts 330 on the screws 320 needs to be adjusted). Then, the position of the anti-loosening nuts 330 on the screws 320 is adjusted, that is, the distance close to the central shaft 310, thereby adjusting the centrifugal force stability when the entire roller body 250 rotates, so that the roller body 250 is more stable when rotating.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
