Description

Technical Field

[0001] The utility model belongs to the technical field of roller conveyor accessories, in particular to a sprocket wheel used for a roller conveyor. Background Art

[0002] Roller conveyor is a kind of material conveying equipment widely used in industrial production and logistics warehousing. Roller conveyor can play an important role in various production lines, warehouses, port terminals and construction sites. The material can change direction during the conveying process. At the same time, by adjusting the spacing and rotation speed of the rollers, the conveying speed and amount of the material can be accurately controlled. Among them, the sprocket is an indispensable and important component of the roller conveyor. However, in the prior art, the sprocket is easy to over-match with the roller and easy to penetrate into the roller, which is not conducive to the actual use of the user.

[0003] The existing patent literature discloses a utility model patent for a high-seal sprocket wheel (publication number: CN220281532U). Its technical solution records that it includes a wheel body and a main shaft passing through the wheel body. No limiting part is set on the main shaft. During the actual installation process, the above-mentioned problems also exist. It is easy to over-fit with the components and penetrate into the components, which is not conducive to the actual use of the user. Utility Model Content

[0004] The utility model aims to provide a technical solution for a sprocket for a roller conveyor in view of the deficiencies in the prior art. The utility model has strong practicality, stable structure, efficient transportation and high durability. The limiting ring divides the connecting cylinder into two parts to achieve regionalization, which is convenient for the actual installation of the staff and improves the assembly efficiency. The utility model has a stable structure, long service life and high conveying efficiency. At the same time, it can also play a limiting role to avoid over-fitting when the sprocket is connected to the roller.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The sprocket for the roller conveyor includes a connecting tube and a sprocket part. A limiting ring is arranged on the connecting tube. The limiting ring divides the connecting tube into a mounting part and a placement part. The sprocket part is installed on the placement part to realize the installation of the sprocket part on the connecting tube. The limiting ring divides the connecting tube into a mounting part and a placement part, so that the structure of the sprocket is more stable and the material transportation efficiency is high. The mounting part is connected to the outer shell of the roller, and the sprocket part is easy to mesh with the chain, which ensures the continuous and stable operation of the roller conveyor and improves the transportation efficiency.

[0007] Furthermore, the chain tooth portion includes teeth and a disc, and the teeth are evenly distributed on the disc in the circumferential direction, and a tooth pit is formed between two teeth. The disc serves as a supporting structure for the teeth, which increases the overall structural strength. The design of the teeth enables the chain tooth portion to effectively engage and transmit power, thereby improving the transmission efficiency. The circumferentially even distribution of the teeth ensures that the chain tooth portion can maintain a stable operating state during the rotation process, thereby reducing the vibration and noise caused by the uneven distribution of the teeth. The design of the tooth pit helps to ensure the precise engagement between the teeth, improve the accuracy and stability of the transmission, and facilitate the addition of lubricating oil.

[0008] Furthermore, an arc segment is provided between the two teeth, and the inclined segments of the two teeth and the arc segment form a tooth socket, which is an arc-shaped structure. The tooth socket with an arc-shaped structure can better distribute lubricating grease, ensure that the teeth are fully lubricated during rotation and engagement, and can also enhance the anti-fracture ability of the chain tooth part, improve the stability and reliability of the overall structure, and the curvature of the arc-shaped tooth socket can match the contour of the teeth, making the teeth more accurate and stable when engaging.

[0009] Furthermore, the left and right end faces of the teeth are curved segments, the top face of the teeth is a flat segment, and the end of the curved segment close to the disc is bent toward the direction of the curved surface close to the flat segment. The bent structure of the curved segment enables the teeth to better disperse and bear the load when subjected to external forces, and at the same time helps to evenly distribute the lubricating grease between the teeth. The design of the flat segment also facilitates subsequent surface treatment and coating processes, improving the surface quality and wear resistance of the teeth.

[0010] Furthermore, two sprocket parts are provided, and the two sprocket parts are equidistantly distributed on the placement part. By providing two sprocket parts, dual-path transmission can be achieved, thereby improving the overall transmission efficiency. The equidistant distribution helps to reduce vibration and deformation caused by uneven force, and improves the stability and reliability of the system.

[0011] Furthermore, one end of the limiting ring close to the installation part is a smooth surface, and one end of the limiting ring close to the placement part is an arc surface. The design of the smooth surface makes the installation of the sprocket and the roller more secure, ensuring the close fit between the sprocket and the roller, and the arc surface avoids sharp points that may cause damage to workers and other work parts, while also improving the aesthetics.

[0012] Furthermore, an installation channel is provided through the connecting tube, a step groove 1 is formed between one end of the installation channel and the inner wall of the installation portion, and a step groove 2 is formed between the other end of the installation channel and the inner wall of the placement portion. The installation channel facilitates the installation of the rotating shaft, and the design of the step groove 1 and the step groove 2 can ensure the accurate positioning and fixation of the components during the installation process, simplifying the installation steps and improving the installation efficiency.

[0013] Furthermore, the sprocket part and the connecting cylinder are both integrally formed structures, which enhances the strength and stability of the entire structure, prolongs the service life, simplifies the manufacturing process, improves production efficiency and reduces manufacturing costs.

[0014] Furthermore, the connecting tube and the chain teeth are both made of C45 carbon steel, which has high hardness and strength, can effectively withstand large workloads, and maintain stable performance during long-term operation, and has good wear resistance, which can ensure that the chain teeth can maintain a long service life under high-intensity and high-frequency friction conditions.

[0015] Furthermore, the connecting tube is a cylindrical structure with a wide top and a narrow bottom. The wide mouth design makes it easier to align and fix during installation, while the narrow mouth part can be tightly inserted into the corresponding installation hole or component, reducing shaking and looseness, ensuring the stability and reliability of transmission, and having a compact structure and a reasonable shape.

[0016] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0017] The utility model has stable structure, efficient transportation, high durability and strong practicality. The limit ring divides the connecting tube into the installation part and the placement part, making the structure of the sprocket more stable, the material transportation efficiency is high, and the chain tooth part is easy to mesh with the chain, ensuring the continuous and stable operation of the roller conveyor and improving the transportation efficiency. The circumferential uniform distribution of the teeth makes the force distribution of the chain tooth part more uniform when transmitting power, reducing the wear and failure caused by uneven force distribution, improving the stability and reliability of the entire transmission system, ensuring that the chain tooth part can maintain a stable operating state during the rotation process, and reducing the vibration and noise caused by uneven tooth distribution.

DETAILED DESCRIPTION

[0024] like Figures 1 to 4 As shown, the utility model is a sprocket for roller conveyor, including a connecting tube 1 and a sprocket part 2. A limiting ring 3 is arranged on the connecting tube 1. The limiting ring 3 divides the connecting tube 1 into a mounting part 4 and a placement part 5. The sprocket part 2 is installed on the placement part 5 to realize the installation of the sprocket part 2 on the connecting tube 1. The structure is stable, the transportation is efficient, and the durability is strong. The limiting ring 3 divides the connecting tube 1 into the mounting part 4 and the placement part 5, so that the structure of the sprocket is more stable, and it can maintain good performance under high load and long-term operation, has a long service life, and has high material transportation efficiency. The mounting part 4 is connected to the outer shell of the roller, and the sprocket part 2 is easy to mesh with the chain, which ensures the continuous and stable operation of the roller conveyor and improves the transportation efficiency.

[0025] The sprocket part 2 includes teeth 6 and a disc 7. The teeth 6 are evenly distributed on the disc 7 in the circumferential direction, and a tooth socket 8 is formed between two teeth 6. The disc 7 serves as a supporting structure for the teeth 6, which increases the overall structural strength, allowing the sprocket part 2 to withstand a larger load and a higher rotation speed. The design of the teeth 6 enables the sprocket part 2 to effectively engage and transmit power, thereby improving the transmission efficiency. The circumferentially even distribution of the teeth 6 makes the force distribution of the sprocket part 2 more even when transmitting power, thereby improving the stability and reliability of the entire transmission system, and ensuring that the sprocket part 2 can maintain a stable operating state during rotation and avoid noise. The design of the tooth socket 8 helps to ensure accurate engagement between the teeth 6, improve the accuracy and stability of the transmission, and the teeth 6 can smoothly enter and exit the tooth socket 8 during rotation, thereby avoiding errors and deviations caused by inaccurate engagement, and reducing the noise and vibration generated by the teeth 6 during engagement, while facilitating the addition of lubricating oil.

[0026] An arc section is provided between the two teeth 6, and the inclined sections of the two teeth 6 and the arc form a tooth socket 8, and the tooth socket 8 is an arc structure. The tooth socket 8 with an arc structure can better store and distribute lubricating grease, ensure that the teeth 6 are fully lubricated during rotation and engagement, reduce friction and wear between the teeth 6, and increase the service life of the chain tooth part 2. It can also reduce the phenomenon of stress concentration, enhance the anti-fracture ability of the chain tooth part 2, and improve the stability and reliability of the overall structure. The curvature of the arc tooth socket 8 can match the profile of the teeth 6, making the teeth 6 more accurate and stable when engaging, further reducing the gap and misalignment between the teeth 6, improving the accuracy and efficiency of the transmission, and at the same time making the operation of the chain tooth part 2 more stable. The arc tooth socket 8 is relatively simple to manufacture and is also easy to clean and inspect.

[0027] The left and right end faces of the tooth 6 are curved segments 9, and the top face of the tooth 6 is a plane segment 10. The end of the curved segment 9 close to the disc 7 is gathered and bent in the direction of the curved surface close to the plane segment 10. The design of the curved segment 9 enables the tooth 6 to better adapt to and match the tooth shape of the other party when biting, improves the stability and accuracy of the transmission, and reduces the wear and noise caused by poor biting. The gathered and curved structure of the curved segment 9 enables the tooth 6 to better disperse and bear the load when subjected to external force, and at the same time helps to evenly distribute the lubricating grease between the teeth 6. The design of the plane segment 10 also facilitates the subsequent surface treatment and coating process, and improves the surface quality and wear resistance of the tooth 6.

[0028] Two sprocket parts 2 are provided, and the two sprocket parts 2 are equidistantly distributed on the placement part 5. By providing two sprocket parts 2, dual-path transmission can be realized, thereby improving the overall transmission efficiency, being able to better share the load, reducing the wear and failure caused by load concentration, making the transmission more efficient and stable, and the equidistant distribution helps to reduce the vibration and deformation caused by uneven force, improving the stability and reliability of the system, and the two sprocket parts 2 share the load together, and the force condition of each sprocket part 2 is relatively balanced, reducing the wear and damage caused by overload, helping to extend the service life of the sprocket part 2, and improving the durability and reliability of the entire transmission system.

[0029] The end of the limiting ring 3 close to the mounting portion 4 is a smooth surface 11, and the end of the limiting ring 3 close to the placement portion 5 is an arcuate surface 12. The design of the smooth surface 11 makes the installation of the sprocket and the roller more secure, ensures the close fit between the sprocket and the roller, and reduces the risk of loosening or falling off due to improper installation. The limiting ring 3 realizes the connection transition with the placement portion 5 through the arcuate surface 12, and the arcuate surface 12 avoids sharp points that may cause damage to workers and other work parts, while also improving the aesthetics.

[0030] The connecting tube 1 is provided with an installation channel 13, a step groove 14 is formed between one end of the installation channel 13 and the inner wall of the installation portion 4, and a step groove 2 15 is formed between the other end of the installation channel 13 and the inner wall of the placement portion 5. The installation channel 13 facilitates the installation of the rotating shaft, and the design of the step groove 14 and the step groove 2 15 can ensure the accurate positioning and fixation of the components during the installation process, simplify the installation steps, and improve the installation efficiency.

[0031] The sprocket part 2 and the connecting tube 1 are both integrally formed. The integrally formed structure design eliminates potential failure points caused by improper or loose joints, thereby enhancing the strength and stability of the entire structure, with high structural strength and long service life. The integrally formed structure simplifies the manufacturing process and is easy to process without additional connectors or joints, thereby improving production efficiency and reducing manufacturing costs.

[0032] The connecting tube 1, the sprocket part 2 and the limit ring 3 are all made of C45 carbon steel. It has high hardness and strength, can effectively bear large workloads, and maintain stable performance during long-term operation. It also has good wear resistance, can ensure that the sprocket part 2 can still maintain a long service life under high-intensity and high-frequency friction conditions, and is easy to process.

[0033] The connecting tube 1 is a cylindrical structure that is wide at the top and narrow at the bottom. The cylindrical structure that is wide at the top and narrow at the bottom enables the connecting tube 1 to better withstand and disperse the stress from the sprocket part 2. When the sprocket part 2 is working, it will generate a certain amount of tension and pressure. The structural design of wide at the top and narrow at the bottom allows these forces to be evenly distributed on the larger cross-section of the connecting tube 1, reducing stress concentration and improving the overall strength and stability. The wide-mouth design makes it easier to align and fix during installation, while the narrow-mouth part can be tightly inserted into the corresponding installation hole or component to reduce shaking and looseness, ensuring the stability and reliability of the transmission. At the same time, whether it is connected with other components or the overall layout arrangement, it can provide sufficient flexibility and adaptability, making the entire transmission system easier to integrate and deploy.

[0034] The roller is connected to the mounting part 4, and the limiting ring 3 can prevent the connecting tube 1 from excessively penetrating into the interior of the roller, thereby playing a certain limiting role. At the same time, the end of the limiting ring 3 close to the mounting part 4 is a smooth surface 11, which can fit tightly with the roller. The two sprocket parts 2 can realize double-chain transmission, and the installation channel 13 is convenient for the installation and placement of the rotating shaft. The connecting tube 1 is a cylindrical structure that is wide at the top and narrow at the bottom. The wide-mouth design makes it easier to align and fix during installation, while the narrow-mouth part can be tightly inserted into the corresponding mounting hole or component. After the installation is completed, the rotating shaft rotates, and the sprocket part 2 rotates synchronously, thereby driving the rotation of the roller to realize transportation.
