A Chain Coupling is a mechanical device used to transmit torque between two shafts while accommodating minor misalignments. It consists of two hubs with sprockets connected by a double-strand roller chain, providing flexibility and durability in various industrial applications.
| Model | Bore Range (mm) | Max Torque (Nm) | Max Speed (RPM) | Weight (kg) |
|---|---|---|---|---|
| CC-100 | 10-25 | 120 | 5000 | 0.8 |
| CC-200 | 20-40 | 350 | 4000 | 1.5 |
| CC-300 | 30-60 | 800 | 3000 | 3.2 |
| CC-400 | 40-80 | 1500 | 2500 | 5.7 |
| CC-500 | 50-100 | 2500 | 2000 | 9.0 |
Proper installation ensures optimal performance and longevity of the chain coupling. Follow these steps:
Chain couplings are widely used in industries such as:
| Coupling Type | Advantages of Chain Coupling |
|---|---|
| Gear Coupling | Lower cost, easier maintenance, and better tolerance for misalignment |
| Elastomeric Coupling | Higher torque capacity and no need for elastic elements that wear out |
| Grid Coupling | Simpler design with fewer parts, reducing failure points |
What is the maximum misalignment a chain coupling can handle?
Chain couplings can typically accommodate up to 0.5 degrees of angular misalignment, 0.015 inches per inch of parallel misalignment, and minor axial movement, but exact values depend on the model and size. Always refer to the manufacturer's specifications for precise limits.
How often should I lubricate the chain in a chain coupling?
Lubrication frequency depends on operating conditions, such as speed, load, and environment. For standard applications, lubricate every 3-6 months with a high-quality, extreme-pressure lubricant. In high-speed or dirty environments, more frequent lubrication may be necessary to prevent wear.
Can chain couplings be used in high-temperature environments?
Yes, but with limitations. Standard chain couplings operate effectively up to 250°F (121°C). For higher temperatures, special materials like heat-treated alloys or stainless steel chains are available. Consult the manufacturer for options suitable above 250°F.
What are the signs that a chain coupling needs replacement?
Common indicators include excessive noise (e.g., grinding or rattling), visible wear or stretching of the chain, corrosion that affects performance, increased vibration, or difficulty in transmitting torque. Regular inspections help identify these issues early.
Is it possible to customize a chain coupling for specific applications?
Absolutely. Many manufacturers offer customizations, including special bore sizes, keyways, materials for corrosive environments, and coatings for high wear resistance. Provide details of your application to get a tailored solution.
How do I select the right size chain coupling for my application?
Consider factors such as torque requirements, shaft sizes, misalignment levels, operating speed, and environmental conditions. Use the manufacturer's selection charts or software, which factor in service conditions and safety margins to ensure optimal performance.
Are chain couplings suitable for reversing or bidirectional applications?
Yes, chain couplings are designed to transmit torque equally in both directions, making them ideal for reversing drives. Ensure proper lubrication and alignment to handle directional changes without issues.
What maintenance tools are required for chain couplings?
Basic tools include wrenches for fastener adjustment, a lubricant gun for chain lubrication, calipers for measuring wear, and alignment tools for periodic checks. Always follow the manufacturer's guidelines for specific tools and procedures.
