Description

Technical Field

[0001] The invention relates to the technical field of sprockets, in particular to a quenched and hardened wear-resistant sprocket. Background Art

[0002] Quenching and hardening wear-resistant sprockets, as a key transmission component, are widely used in various types of mechanical equipment, especially in situations where they need to withstand high loads, high speeds and harsh working environments. Their performance directly affects the efficiency and stability of the entire transmission system. The quenching and hardening treatment is to heat the sprocket to a specific temperature and then quickly cool it to form a uniform and dense hardened layer inside the material, thereby significantly improving the hardness, wear resistance and fatigue resistance of the sprocket. The design of the wear-resistant sprocket further enhances the durability of the sprocket under long-term, high-intensity working conditions, reducing the decrease in transmission efficiency and the increase in failure rate due to wear. Therefore, quenching and hardening wear-resistant sprockets have become an important choice for improving the transmission performance of mechanical equipment and extending its service life.

[0003] Traditional sprocket manufacturing technology has many shortcomings in quenching hardening treatment and wear-resistant design. On the one hand, it is often difficult to accurately control the cooling rate and temperature distribution of traditional quenching processes, resulting in uneven stress distribution inside the sprocket, which is prone to deformation and cracks, affecting the dimensional accuracy and overall performance of the sprocket. Under high-speed operation or heavy load conditions, thermal stress concentration is easy to cause cracks or fractures in the teeth, shortening the life of the sprocket. At the same time, under high-speed operation or heavy load conditions, thermal stress concentration is easy to cause cracks or fractures in the teeth, shortening the life of the sprocket. On the other hand, traditional wear-resistant design mostly relies on the hardness improvement of the material itself or simple surface coating treatment, which is difficult to maintain long-term and stable wear resistance under complex working conditions. In addition, traditional sprockets lack modular design, and the transmission system needs to be disassembled as a whole for maintenance, which is time-consuming and labor-intensive, and the cost of downtime maintenance is high. These shortcomings not only limit the application of sprockets in high-end equipment and extreme working conditions, but also increase the maintenance cost and downtime of the equipment, which has a negative impact on production efficiency and economic benefits. Therefore, developing a quench-hardened wear-resistant sprocket that can effectively disperse quenching stress, improve wear resistance and is easy to manufacture and maintain has become a key issue that needs to be urgently solved in the current field of transmission components. For this reason, we propose a quench-hardened wear-resistant sprocket. Summary of the invention

[0015] Compared with the prior art, the present invention provides a quenched and hardened wear-resistant sprocket, which has the following beneficial effects:

[0016] 1. The quenched and hardened wear-resistant sprocket adopts a segmented design. The female section wheel and the male section wheel are precisely fitted inside, effectively dispersing the thermal stress. During the quenching and hardening process, this design can reduce the overall deformation of the sprocket and ensure the dimensional accuracy. In contrast, traditional sprockets are prone to deformation due to stress concentration during quenching, affecting the transmission accuracy. This device solves this problem through an optimized structural design, enabling the sprocket to maintain high-precision dimensions during manufacturing and use, and improving the overall performance of the transmission system.

[0017] 2. The quenched and hardened wear-resistant sprocket realizes the convenient installation and disassembly of the sprocket through the fitting design of the locking seat and the second locking seat, as well as the quick connection structure of the quick connector and the quick connection seat. When maintaining or replacing the sprocket, it can be quickly completed without complex tools and operations. The installation and disassembly of traditional sprockets are often cumbersome, time-consuming and laborious. The design of this device greatly shortens the maintenance time, reduces the maintenance cost, and improves the availability of the equipment.

[0018] 3. The quenched and hardened wear-resistant sprocket enhances the connection strength and stability between sprockets through the precise cooperation of components such as the locking seat bolts, the meshing tooth grooves of the connecting shaft, and the locking cover. During the transmission process, all components can cooperate closely to reduce failures caused by loosening or falling off. Traditional sprockets often have deficiencies in terms of connection strength and stability, which are prone to cause transmission failures. The application of this device improves the reliability of the transmission system and ensures the normal operation of the equipment.

[0019] 4. The quenched and hardened wear-resistant sprocket fully considers the usage requirements under harsh working conditions. For example, the application of sandblasting and film coating not only improves the hardness and wear resistance of the sprocket surface, but also enhances its corrosion resistance. In humid, dusty or corrosive environments, this sprocket can maintain stable performance and extend its service life. Traditional sprockets are easily damaged under harsh working conditions, affecting the service life and transmission performance. The design of this device enables the sprocket to adapt to a wider range of working environments and improves the adaptability and durability of the equipment.

[0020] 5. The design of the limiting groove, the second limiting groove, the connecting groove, and the second connecting groove of the quenched and hardened wear-resistant sprocket provides precise positioning and connection for components such as the connecting shaft and the locking cover, ensuring the stability and precision of the sprocket during operation. The locking cover is tightly connected to the locking seat and the second locking seat through the connecting rubber ring and the limiting block, preventing the connecting shaft from loosening or falling off during operation, and improving the safety and reliability of the sprocket.

[0021] 6. The quenched and hardened wear-resistant sprocket fully considers the actual requirements of the transmission system in its structural design. Through various methods such as segmented design, fitting structure, and threaded connection, it realizes the high strength, high wear resistance, high stability, and convenient maintenance and replacement of the sprocket. This optimized structural design enables the sprocket to adapt to a wider range of working environments and improves the adaptability and durability of the equipment.

When disassembly is required, simply rotate the locking wrench 29 to easily separate the quick connector 23 from the quick connection seat 27 to achieve quick disassembly.

[0042] Further, a sandblasted film 30 is coated on the outer walls of the female section wheel 1 and the male section wheel 2 away from the locking seat 5. The presence of the sandblasted film 30 effectively protects the surface of the sprocket from wear and corrosion, extends the service life of the sprocket. At the same time, by increasing the friction between the sprocket and the chain, the transmission efficiency is improved, energy loss is reduced, thereby improving the performance of the entire transmission system.

Sandblasting and film coating 30: Improves the hardness and wear resistance of the sprocket surface, enhances the friction between the sprocket and the chain, and improves the transmission efficiency and stability; is coated on the outer walls of the female section wheel 1 and the male section wheel 2 on the side away from the locking seat 5.

[0074] Working principle: First, the female segment wheel 1 and the male segment wheel 2 are the main parts of the sprocket. Through the precise fitting design on their inner sides, seamless splicing is achieved, and they jointly form a complete sprocket tooth profile. This segmented design not only facilitates the manufacturing and maintenance of the sprocket, but more importantly, during the quenching and hardening process, the female segment wheel 1 and the male segment wheel 2 can independently bear the thermal stress, effectively disperse the thermal stress, reduce the overall deformation, and thus improve the dimensional accuracy and stability of the sprocket. When the chain meshes with the sprocket, the tooth profiles of the female segment wheel 1 and the male segment wheel 2 act on the chain together to achieve efficient power transmission. The fixing groove 3 opened on the outer wall of one side of the female segment wheel 1 and the male segment wheel 2, and the fixing ring 7 provided on one side of the inner wall of the fixing groove 3, through the threaded connection of the bolt 8 and the threaded hole 4, realize the stable fixation of the sprocket and the transmission system. This design not only improves the installation efficiency of the sprocket, but also ensures the stability and reliability of the sprocket during the transmission process. The tight fitting of the fixing ring 7 and the firm connection of the bolt 8 jointly constitute a solid bridge between the sprocket and the transmission system. The locking seat 5 and the second locking seat 6 are respectively arranged on the outer walls of the female segment wheel 1 and the male segment wheel 2 close to the fixing groove 3. Through their fitting design, the precise positioning of the female segment wheel 1 and the male segment wheel 2 is realized. The locking seat thread groove 11 and the second locking seat thread groove 12 opened on the inner walls of the locking seat 5 and the second locking seat 6, and the threaded connection of the locking cover 19 through the locking seat bolt 22 further enhance the connection strength and stability between the female segment wheel 1 and the male segment wheel 2. At the same time, the meshing connection between the meshing tooth groove 18 opened on the outer wall of one end of the connecting shaft 17 and the inner walls of the tooth groove 9 and the second tooth groove 10 realizes the power transmission between the connecting shaft 17 and the female segment wheel 1 and the male segment wheel 2, ensuring the smoothness and accuracy of the sprocket rotation. The quick connector 23 movably connected to the outer wall of one side of the locking cover 19, through the coordinated use of its unique guide groove 24, annular locking groove 25, limiting strip 26, as well as the quick connection seat 27 and the locking wrench 29, realizes the quick connection and disassembly between the sprocket and the transmission system. This design not only improves the installation and maintenance efficiency of the sprocket, but also ensures the tightness and stability of the connection part. When disassembly is required, simply rotate the locking wrench 29 to easily separate the quick connector 23 from the quick connection seat 27 to achieve quick disassembly. The sandblasting coating film 30 applied to the outer walls of the female segment wheel 1 and the male segment wheel 2 away from the locking seat 5 not only improves the surface hardness and wear resistance of the sprocket, but also enhances the friction between the sprocket and the chain, thereby further improving the transmission efficiency and stability of the sprocket. The presence of the sandblasting coating film 30 enables the sprocket to maintain stable performance during long-term and high-load transmission processes, extending the service life of the sprocket.
