Description of Serrated Connection Ring
The Sawtooth Connection Ring is a specialized fastener integral to the robust functioning of mechanical chain connections. Predominantly utilized in the realm of mining equipment, scraper conveyors, and other similar scenarios, this ring facilitates a high-strength lock and steadfast connection. Its secret lies in its uniquely engineered serrated structure. Delve into its comprehensive description below:
1, Basic Definition
The Sawtooth Connecting Ring, also known by its aliases as the saw tooth chain link or saw tooth ring, is an indispensable connecting element in mining circular chains. Primarily appointed for chain connections in scraper conveyors, transfer machines, and an array of equipment, its design mimics the formidable saw blade. This ingenious design ensures load transmission through the harmonious meshing of multiple, equidistant serrations.
2, Structural Design
1. Tooth Profile Characteristics:
The serrated connecting ring is characterized by two semi-circular rings held together with resilient elastic pins. It boasts sharp teeth with minimal spacing, crafting a meshing surface akin to a saw blade, optimized for superior engagement.
Certain models offer the versatility of horizontal or vertical installation, catering to diverse directional requirements in chain connection.
2. Material and Craftsmanship:
Crafted from high-strength alloy steel such as 23MnNiMoCr54, this connecting ring encapsulates toughness and fatigue resistance. Its surface treatment for anti-corrosion ensures it thrives in underground environments.
3, Performance Characteristics
High Locking Force: Thanks to its serrated structure, the ring ensures uniform load dissemination with a remarkable breaking load capacity of up to 1450kN, making it ideal for high-load applications.
Flexible Installation: With no specific directional constraints, this ring is compatible with both horizontal and vertical connections, simplifying the assembly and disassembly process.
Limitations: The compact tooth profile can occasionally induce stress concentration, posing risks of tooth breakage or detachment, necessitating regular inspections and maintenance.
4, Application Scenarios
1. Mining Equipment:
Vital for connecting the mining circular chains of scraper conveyors and transfer machines, it efficiently transmits traction force while bearing substantial impact loads.
2. Industrial Equipment:
An optimal replacement for bolt connections in coal plows and heavy-duty conveying machinery, overcoming challenges related to rust and disassembly.
5, Precautions
1. Matching Requirements:
It is imperative to meticulously match the sprocket and chain sizes to prevent installation deviations, which could lead to wear or breakage.
2. Installation Specifications:
Ensure the contact surface is spotless before installation, void of impurities that might hinder engagement; refrain from inserting additional accessories between connecting rings.
3. Maintenance Inspection:
Conduct thorough inspections for tooth wear and cracks every three months, or following the throughput of 1 million tons of coal, ensuring timely replacement of damaged parts.

6, Compare and Improve Models
1. Comparison with Arc Gear Ring:
The serrated ring, with its acutely pointed teeth, delivers robust locking force but is susceptible to stress concentrations. Conversely, the arc tooth ring features a circular arc tooth surface, promoting a larger contact area and boasting over 50,000 cycles in fatigue life.
2. Comparison with Ladder Gear Ring:
The ladder-toothed ring is an evolution of the serrated design, marked by trapezoidal teeth and curved corners, significantly minimizing stress concentration and enhancing fracture strength.
In summary, the Serrated Connecting Ring, celebrated for its exceptional locking force and versatile installation, stands as a cornerstone in mining machinery chain connections. Yet, for high-impact scenarios, innovation in design—by integrating arc or ladder toothed rings—can substantially bolster reliability.
