Description of serrated connection ring
The sawtooth connection ring is an advanced fastener crafted for the robust mechanical chain connections, predominantly utilized in mining machinery, scraper conveyors, and other demanding applications. With its innovative serrated design, it ensures high-strength locking and unwavering stability. Explore its comprehensive attributes below:
1, Basic Definition
The sawtooth connecting ring, also known as the saw tooth chain link or saw tooth ring, is an integral connecting element for mining circular chains. Primarily employed in the assembly of scraper conveyors, transfer machines, and related equipment, its distinctive saw blade-like tooth configuration efficiently transmits load through precisely arranged, equidistant serrations.
2, Structural Design
1. Tooth profile characteristics:
This ingeniously designed serrated connecting ring features two semi-circular rings held together by resilient elastic pins. The finely sharpened teeth and closely spaced structure create a meshing surface akin to a saw blade, providing remarkable mechanical interlocking.
Select models are engineered for versatile installation, accommodating horizontal or vertical orientations to meet diverse directional chain connection requirements.
2. Material and craftsmanship:
Constructed from high-strength alloy steel, such as 23MnNiMoCr54, the ring boasts exceptional toughness and fatigue resistance. Its surface is available with anti-corrosion treatment, ensuring durability in the subterranean environments.
3, Performance characteristics
Unparalleled locking force: Thanks to its serrated structure, it ensures uniform load distribution and can withstand an incredible breaking load of up to 1450kN, making it ideal for high load applications.
Effortless installation: With no stringent directional constraints, it seamlessly supports both horizontal and vertical connections, facilitating swift and easy assembly or disassembly.
Considerations: The compact tooth profile may lead to stress concentration, potentially causing tooth breakage or detachment. Routine inspection and maintenance are advised to avert such issues.
4, Application scenarios
1. Mining equipment:
Integral in connecting mining circular chains for scraper conveyors and transfer machines, it effectively transmits traction forces and withstands impact loads.
2. Industrial equipment:
Acts as an innovative alternative to bolt connections in coal plows and heavy-duty conveying machines, solving rust-related issues and simplifying disassembly processes.
5, Precautions
1. Matching requirements:
Ensure precise matching of sprocket and chain sizes to eliminate installation deviations that might lead to wear or breakage.
2. Installation specifications:
Thoroughly clean the contact surfaces prior to installation to remove impurities that could hinder engagement; refrain from inserting external accessories between the connecting rings.
3. Maintenance inspection:
Conduct inspections for tooth wear and cracks every three months or after a throughput of 1 million tons of coal, promptly replacing any damaged parts.

6, Compare and improve models
1. Comparison with arc gear ring:
Serrated ring: Features sharp tooth tips and exceptional locking force, albeit with potential stress concentration; The arc tooth ring, with its circular arc tooth surface, provides a larger contact area, enhancing fatigue life to surpass 50,000 cycles.
2. Comparison with ladder gear ring:
The ladder toothed ring refines the serrated design with optimized trapezoidal teeth and smooth corners, significantly diminishing stress concentration and boosting fracture strength.
In conclusion, the serrated connecting ring stands as an essential component for mining machinery chain connections, celebrated for its formidable locking force and adaptable installation. Nonetheless, for high-impact settings, it is imperative to enhance the design by integrating arc toothed or ladder toothed rings to bolster reliability.
