Description

Technical Field

[0001] This utility model relates to the field of industrial chain technology, specifically a high-strength, wear-resistant industrial chain. Background Technology

[0002] In the vast field of industrial production, industrial chains, as core components for material transportation and mechanical transmission, are widely used in various production lines. They play an indispensable role in industries such as automobile manufacturing, food processing, mining, and metallurgy. In the automobile manufacturing sector, industrial chains bear the heavy responsibility of accurately transporting parts to various workstations to ensure the smooth operation of the production line. In the mining sector, chains need to operate for long periods of time in harsh environments to drive conveying equipment and complete the transportation of ore.

[0003] However, traditional industrial chains have revealed many problems in actual use. Under high-friction conditions, most wear is caused by insufficient lubrication between chain components, leading to increased dry friction. As a result, the chain structure is prone to wear, deformation, and even breakage. This not only shortens the chain's service life but also leads to frequent downtime for maintenance and replacement, seriously affecting production efficiency and increasing the company's operating costs. Furthermore, if the chain fails during operation, it is highly likely to cause equipment failure, resulting in production accidents and threatening the lives of operators. Therefore, we propose a high-strength, wear-resistant industrial chain. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-strength, wear-resistant industrial chain, solving the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a high-strength wear-resistant industrial chain, comprising an inner link, a roller, an outer link, an outer link plate, a fixing member, and a fixing bolt. The inner link has two axially symmetrically distributed sleeves inside. Rollers are fitted around the outside of the sleeves, and the rollers are rotatably connected to the inside of the sleeves. An outer link and an outer link plate are located on one side of the inner link's shaft end. The outer link and the outer link plate are rotatably connected around the sleeves. A fixing member is located on the side of the outer link plate opposite to the outer link, and the fixing member is correspondingly attached to the side wall of the outer link plate. A fixing bolt is radially located on the side of the fixing member opposite to the outer link plate, and the fixing bolt fixes the outer link and the fixing member.

[0006] Preferably, the inner link has two sleeves arranged symmetrically inside, and the shaft ends on both sides of the sleeves have mating blocks arranged symmetrically. A set of curved plates is provided on the opposite side of the two mating blocks, and a sealing groove is provided on the outer side of the curved plates. Two sets of cross-wound lubricating oil grooves are provided on the cylindrical outer side of the sleeves, and an oil inlet hole is provided at the center of the circular sidewall of the mating block. The oil inlet hole is connected to the shaft end on one side of the lubricating oil groove.

[0007] Preferably, the outer link sidewall is provided with two axially symmetrically distributed pins, and the pins are rotatably connected to the inside of the sleeve. The pin ends are connected to the outer link plate, and a fixing hole is radially opened on the pin ends. The fixing hole passes through the pin and is connected to a fixing bolt.

[0008] Preferably, the roller has a set of two curved plates distributed symmetrically at its two opposite shaft ends. The two curved plates are connected to the first curved plate in a cross-fitting manner, and a sealing groove is formed on the outer side of the two curved plates.

[0011] Compared with the prior art, this utility model provides a high-strength, wear-resistant industrial chain with the following advantages:

[0012] 1. This high-strength, wear-resistant industrial chain significantly improves wear resistance. Through its unique lubrication groove design, the industrial chain continuously lubricates the friction surfaces of the rollers and bushings, effectively reducing dry friction and greatly improving wear resistance. With its excellent lubrication system, this chain can operate stably for a long time, greatly extending its service life, reducing the frequency of chain replacement, lowering equipment maintenance costs, and improving production efficiency.

[0013] 2. This high-strength, wear-resistant industrial chain is adaptable to harsh environments and ensures safe operation. The chain employs a curved oil seal structure and sealing rubber rings, giving it strong environmental adaptability and excellent sealing performance. Under harsh conditions such as high temperature, high pressure, and dust, the curved oil seal effectively prevents impurities from entering the chain, while reducing frictional wear and ensuring stable chain operation. This not only reduces the risk of equipment failure and production accidents caused by chain failure, protecting the lives of operators, but also ensures the continuity of industrial production, avoiding production stoppages due to equipment failure, and providing strong support for the safe production and stable operation of enterprises.

The fixing bolt 6 fixes the outer link 3 and the fastener 5.

[0024] Furthermore, the inner link 1 has two axially symmetrically distributed sleeves 7 inside, and axially symmetrically distributed mating blocks 8 on both sides of the shaft end of the sleeves 7. A set of curved plates 10 is provided on opposite sides of the two mating blocks 8, and a sealing groove 11 is opened on the outer side of the curved plates 10. Two sets of cross-wound lubricating oil grooves 9 are opened on the cylindrical exterior of the sleeves 7, and an oil inlet hole 12 is opened at the center of the circular sidewall of the mating block 8. The oil inlet hole 12 communicates with the shaft end of one side of the lubricating oil groove 9. The roller 2 is sleeved on the sleeve... After the roller 2 is mounted on the sleeve 7, appropriate lubricating oil is injected through the oil inlet 12 and flows into the two sets of cross-wound lubricating oil grooves 9. The oil inlet 12 is sealed by a specific pin to prevent lubricating oil leakage. The two sets of cross-wound lubricating oil grooves 9 can store a large amount of lubricating oil. The two ends of the two sets of cross-wound lubricating oil grooves 9 are connected, and the lubricating oil can flow freely in the lubricating oil grooves 9, effectively preventing the generation of dry friction, reducing the friction between the inside of the roller 2 and the sleeve 7, and greatly improving the overall wear resistance.

[0025] Furthermore, the outer link 3 has two axially symmetrically distributed pins 13 on its side wall, and the pins 13 are rotatably connected to the inside of the sleeve 7. The end of the pin 13 is connected to the outer link plate 4, and a fixing hole 14 is radially opened on the end of the pin 13. The fixing hole 14 passes through the pin 13 and is connected to the fixing bolt 6. The pin 13 serves to connect the inner link 1, the outer link 3, and the outer link plate 4.

[0026] Furthermore, the roller 2 has a set of axially symmetrical curved plates 15 at its two opposite shaft ends. The curved plates 15 are cross-fitted with the curved plates 10. A sealing groove 16 is formed on the outer side of the curved plates 15. The curved plates 15 are cross-fitted with the curved plates 10 to form a curved oil seal. The curved oil seal is a non-contact sealing method, which makes the roller 2 shaft end and the mating block 8 almost frictionless during operation. This not only reduces energy loss but also greatly extends its service life, eliminating the need for frequent replacement. Moreover, the curved oil seal is highly adaptable to the working environment and can maintain good sealing performance under harsh conditions such as high temperature, high pressure, and dust.

[0027] Furthermore, the second sealing groove 16 corresponds to the first sealing groove 11, and a sealing rubber ring 19 is provided between the second sealing groove 16 and the first sealing groove 11, which further improves the overall sealing performance.

[0028] Furthermore, the fastener 5 has a mating hole 17 inside, which corresponds to the outer side of the pin 13. The fastener 5 also has a through-hole 18 on the side away from the outer chain plate 4. The second fixing hole 18 is concentrically fitted with the first fixing hole 14 by the fixing bolt 6. The fastener 5 ensures the overall connection is stable and is easy to disassemble and assemble.

Rollers 2 are fitted onto the two sleeves 7 of the inner link 1, allowing relative rotation between the rollers 2 and sleeves 7. During installation, lubricating oil is injected into the lubrication grooves 9 of the sleeves 7 through the oil inlet 12. Then, a specific pin seals the oil inlet 12 to prevent lubricating oil leakage. The lubrication grooves 9 are arranged in two sets of cross-winding patterns, capable of storing a large amount of lubricating oil, and are connected at both ends, allowing the lubricating oil to flow freely and continuously provide lubrication to the friction surfaces between the rollers 2 and sleeves 7, effectively reducing dry friction and improving wear resistance. The outer link 3 is rotatably connected to the sleeves 7 of the inner link 1 via a pin 13, and is also connected to the outer link plate 4. The pin 13 not only serves a connecting function, but its fixing hole 14 at the shaft end also connects to the fixing bolt. The bolt 6 securely connects the outer link 3, outer link plate 4, and fixing component 5. The fixing component 5 is sleeved on the outside of the pin 13 through the mating hole 17, and its fixing hole 18 is concentrically mated with the fixing bolt 6, further enhancing the overall connection stability of the chain and facilitating disassembly and assembly. The curved plate 15 at the shaft end of roller 2 cross-fits with the curved plate 10 on the mating block 8 of inner link 1 to form a curved oil seal structure. The curved oil seal adopts a non-contact sealing, with almost no friction when the shaft end of roller 2 works with the mating block 8. This not only reduces energy loss but also adapts to harsh working environments such as high temperature, high pressure, and dust, maintaining good sealing performance. The sealing rubber ring 19 set between the sealing groove 16 and the sealing groove 11 further improves the sealing performance, preventing external impurities from entering the chain and affecting its normal operation. In this way, the tight cooperation of each component ensures the efficient and stable transmission of the chain in industrial production.
