Description

Technical Field

[0001] This utility model relates to the field of sprockets, specifically a wear-resistant sprocket. Background Technology

[0002] Traditional sprockets face numerous problems during long-term use. Because the outer ring and teeth of the sprocket frequently come into contact with and rub against the chain or other roller components during operation, wear easily occurs on the outer ring surface and teeth. This wear is particularly severe under high loads, high speeds, and harsh working environments (such as dusty or humid conditions). Excessive wear on the sprocket not only reduces transmission efficiency and causes equipment instability, but can also lead to chain tooth slippage and skipping, seriously affecting normal equipment operation, even causing equipment damage, increasing maintenance costs and downtime.

[0003] To address these issues, various methods have been attempted. For example, using more wear-resistant materials to manufacture the sprockets often significantly increases costs with limited effectiveness. Another approach is to improve the surface hardness of the sprocket through surface heat treatment, but this method still falls short of the required durability for complex operating conditions. Furthermore, existing sprockets have shortcomings in terms of cleaning and maintenance; dirt and debris easily accumulate between the teeth, further accelerating wear, while conventional cleaning methods are cumbersome and ineffective. Therefore, developing a wear-resistant sprocket that effectively improves wear resistance, is easy to clean and maintain, and is cost-effective is of significant practical importance. To this end, we propose a wear-resistant sprocket. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a wear-resistant sprocket, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a wear-resistant sprocket, comprising an inner body and an outer ring rotatably disposed on the outer side of the inner body, wherein the outer ring is integrally formed with teeth, and mounting recesses are provided on the surface of the outer ring and on the corresponding side of two adjacent teeth, and reinforcing blocks are embedded inside the mounting recesses.

[0006] Preferably, an inner annular groove is formed on the inner wall of the outer ring, and an annular protrusion is integrally formed on the inner main body at the position corresponding to the inner annular groove, and the annular protrusion is rotatably connected to the inner annular groove.

[0007] Preferably, the internal body is provided with a cleaning component for cleaning the teeth.

[0008] Preferably, the cleaning component includes L-shaped blocks fixedly installed on both sides of the inner body and a cleaning brush structure disposed between the two L-shaped blocks.

[0009] Preferably, the cleaning brush structure includes a rectangular movable block and a cleaning brush. The cleaning brush is fixedly installed on one side of the rectangular movable block corresponding to the tooth. A pulling component is provided on the L-shaped block. The pulling component is fixedly connected to the rectangular movable block and pulls the rectangular movable block toward the tooth side.

[0010] Preferably, the L-shaped block has a rectangular opening, and the pulling assembly includes a vertical shaft and a tension spring. The vertical shaft is fixedly installed inside the rectangular opening, and the tension spring is sleeved on the vertical shaft.

[0011] Preferably, a protrusion is fixedly installed at one end of the cleaning brush corresponding to the rectangular opening. The protrusion is slidably engaged with the vertical shaft and keeps in contact with the inner wall of the rectangular opening. One side of the protrusion is fixedly connected to a tension spring.

[0012] Compared with the prior art, the present invention provides a wear-resistant sprocket with the following advantages:

[0013] This wear-resistant sprocket offers several significant advantages. In terms of wear resistance, the strength of easily worn areas is greatly enhanced by creating recesses and inserting reinforcing blocks on the outer ring surface and corresponding sides of adjacent teeth. Facing frequent friction with chains or rollers under high loads, high speeds, and harsh operating conditions, it effectively resists wear, significantly extends the sprocket's service life, reduces equipment failures caused by wear, ensures stable equipment operation, and lowers the overall frequency and cost of equipment maintenance.

[0014] In terms of cleaning and maintenance, the cleaning assembly, consisting of L-shaped blocks and a cleaning brush structure located on both sides of the internal main body, is highly effective. The tension spring in the assembly continuously applies force to the rectangular movable block, causing the cleaning brush fixed to one side to remain in constant contact with the outer wall and teeth of the outer ring. During sprocket operation, it automatically and continuously cleans accumulated dirt and debris from the teeth, preventing accelerated wear due to dirt buildup and ensuring the sprocket is always in good working condition. This also reduces the frequency of manual cleaning and lowers maintenance workload.

[0015] From a cost perspective, compared to simply using expensive wear-resistant materials, this sprocket achieves excellent wear resistance and cleaning performance through structural optimization and component design, without requiring high material costs. It solves the problems faced by traditional sprockets while controlling costs while ensuring performance, offering extremely high cost-effectiveness in many fields such as industrial production and transportation. This facilitates widespread application and brings significant economic benefits to enterprises. Attached Figure Description

[0029] Structural Description:

[0030] Internal main body 1: This is the core part of the sprocket, serving to support and connect other components. It is the basic structure of the entire sprocket, around which other components, such as the outer ring 2, are arranged. L-shaped blocks 4 are fixedly installed on both sides of it to support related components of the cleaning assembly. Simultaneously, at the connection point with the outer ring 2, an annular protrusion 12 is integrally formed at the position corresponding to the annular groove 11 on the inner wall, enabling a rotatable connection with the outer ring 2.

[0031] Outer ring 2: Rotatably mounted on the outer side of the inner body 1, its outer side is integrally formed with teeth 3, which is the key part for the meshing and transmission of sprockets and chains. The surface of the outer ring 2 and the corresponding sides of two adjacent teeth 3 are provided with mounting recesses 13 for inserting reinforcing blocks 14 to enhance the strength and wear resistance of the outer wall surface of the outer ring 2 and the sides of the two adjacent teeth 3. In addition, an inner annular groove 11 is formed on the inner wall of the outer ring 2, which is rotatably connected to the annular protrusion 12 of the inner body 1, allowing the outer ring 2 to rotate flexibly relative to the inner body 1.

[0032] Teeth 3: One-piece molded on the outer side of the outer ring 2, these are crucial structures for the sprocket's transmission function, meshing with components such as the chain to transmit power. Adjacent teeth 3 have corresponding mounting recesses 13 on their sides, inlaid with reinforcing blocks 14. The reinforcing blocks 14 improve the strength and wear resistance of the tooth 3's side surface. Because in actual use, the sides of adjacent teeth 3 come into contact with the connected roller portion and frequently rub against each other, the reinforcing blocks 14, embedded in the mounting recesses 13 (located on the corresponding sides of adjacent teeth 3), enhance the strength and wear resistance of the tooth 3's side surface.

[0033] L-shaped block 4: Fixedly installed on both sides of the internal main body 1, it is an important support component of the cleaning assembly. It has a rectangular opening 5 for installing components such as the vertical shaft 6 of the pulling assembly, and cooperates with components such as the rectangular movable block 8 of the cleaning brush structure to achieve the cleaning function of the teeth 3.

[0034] Rectangular opening 5: This opening is located on the L-shaped block 4 and is used to mount components such as the vertical shaft 6, providing installation space for the pull assembly. Simultaneously, the protruding block 9 of the cleaning brush structure remains in contact with the inner wall of the rectangular opening 5 and slides within it, enabling the position adjustment of the rectangular movable block 8 and the movement of the cleaning brush 10.

[0035] Vertical shaft 6: Fixedly installed inside the rectangular opening 5, it is an important component of the pulling assembly. It provides support for the tension spring 7 and slides into the protrusion 9 of the cleaning brush structure, guiding the protrusion 9 to slide within the rectangular opening 5, thereby achieving the position adjustment of the rectangular movable block 8.

[0036] Tension spring 7: Sleeved onto vertical shaft 6, it is a key component of the pulling assembly. One end of it is fixedly connected to protrusion block 9, and the other end is fixed in a suitable position (not described in detail, but can be inferred from the structure). Through its own elastic tension, it pulls rectangular movable block 8, so that cleaning brush 10 always keeps in contact with the outer wall of outer ring 2 and teeth 3, thereby achieving continuous cleaning of teeth 3.

[0037] Rectangular movable block 8: Located between two L-shaped blocks 4, it is an important component of the cleaning brush structure. A cleaning brush 10 is fixedly installed on one side corresponding to the teeth 3. Through connection with the pulling assembly (vertical shaft 6 and tension spring 7), under the pulling force of the tension spring 7, it can approach or fit against the outer wall of the outer ring 2 and the teeth 3 to achieve cleaning.

[0038] Protrusion 9: Fixedly installed at one end of the cleaning brush 10 corresponding to the rectangular opening 5, slidingly engaged with the vertical shaft 6, and kept in contact with the inner wall of the rectangular opening 5. One side of it is fixedly connected to the tension spring 7. Under the tension of the tension spring 7, it drives the rectangular movable block 8 and the cleaning brush 10 to move, so that the cleaning brush 10 can clean the outer wall surface of the outer ring 2 and the teeth 3.

[0039] Cleaning brush 10: Fixedly installed on one side of the rectangular movable block 8 corresponding to the tooth 3, it is the component that directly cleans the tooth 3. Under the tension of the tension spring 7, the cleaning brush 10 can always adhere to the outer wall of the outer ring 2 and the tooth 3, removing dirt, debris and other substances that may be present on the tooth 3, and maintaining the normal operation of the sprocket.

[0040] Inner wall annular groove 11: It is formed on the inner wall of the outer ring 2 and cooperates with the annular protrusion 12 of the inner body 1 to realize the rotational connection between the outer ring 2 and the inner body 1, so that the outer ring 2 can rotate flexibly relative to the inner body 1 to meet the working requirements of the sprocket.

[0041] Annular protrusion 12: integrally formed on the inner body 1 at the position corresponding to the inner wall annular groove 11, and rotatably connected with the inner wall annular groove 11, providing support and guidance for the rotation of the outer ring 2, ensuring the stability and flexibility of the rotation of the outer ring 2.

[0042] Installation recess 13: This recess is formed on the surface of the outer ring 2 and on one side of the two adjacent teeth 3, for inserting reinforcing blocks 14. By inserting reinforcing blocks 14, the strength of the outer wall of the outer ring 2 and the sides of the two adjacent teeth 3 can be increased, improving its wear resistance and extending the service life of the sprocket.

[0043] Reinforcing block 14: Embedded inside the mounting recess 13, its main function is to increase the strength of the outer wall surface of the outer ring 2 and the sides of the two adjacent teeth 3, thereby improving the wear resistance of these parts. In actual use, since the outer wall surface of the outer ring 2 and the sides of the two adjacent teeth 3 are in contact with and frequently rub against the connected roller portion, the presence of reinforcing block 14 can effectively enhance the performance of these parts.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
