Chain Couplings

A chain coupling is a robust power transmission device using two sprockets and a double-strand roller chain to connect shafts, allowing for easy connection/disconnection and accommodating significant shaft misalignment while transmitting torque, suitable for various industrial uses, especially when lubrication is maintained for high speeds. 

Components

Sprockets: Two sprockets with teeth that mesh with the chain, often hardened for durability.

Roller Chain: A strong, double-strand roller chain wraps around both sprockets.

Split Case (Optional): A two-part housing that covers the coupling for protection and lubrication, often with O-rings to retain grease. 

Key Features & Benefits

Easy Connection: A single pin allows for quick assembly and disassembly, reducing downtime.

High Durability: Torque is shared between the chain and hardened sprocket teeth for robust performance.

Misalignment Compensation: Internal clearances absorb parallel, angular, and axial misalignment between shafts.

Compact & Powerful: Offers high torque capacity for its size.

Versatile: Available in various materials (steel, resin) for different environments, from general power transmission to dirty or corrosive conditions. 

Usage Considerations

Lubrication is Crucial: Requires adequate grease within the cover for high-speed operation and long life; poor lubrication can lead to chain breakage.

Installation: Proper alignment of sprockets and shafts is important for optimal performance.
