Roller Chain Coupling

Understanding Roller Chain Couplings

A roller chain coupling works on the principle of connecting two shaft-mounted sprockets with a double-strand roller chain. The inherent clearances between the chain pins, bushings, rollers, and sprocket teeth allow for slight shaft misalignment while transmitting torque.

Key Advantages:

• High Torque Capacity: Can transmit high torque relative to their physical size due to the strength of the chain and sprockets.
• Simple Construction: Consists of only three main parts: two sprockets and one chain.
• Ease of Assembly/Disassembly: The chain can be easily connected or disconnected using a connecting link, simplifying installation and maintenance.
• Cost-Effective: Generally less expensive than other high-torque flexible coupling types.
• Misalignment Accommodation: Tolerates small amounts of angular and parallel misalignment.
• Compact Design: Offers a relatively small diameter for its torque rating.

Components:

• Sprockets (Hubs): Two identical sprockets, typically made of steel with hardened teeth for wear resistance, bored and keyed to fit the shafts.
• Duplex Roller Chain: A standard double-strand roller chain wraps around both sprockets to transmit power.
• Cover (Optional but Recommended): A split cover (aluminium or plastic) is often used to retain lubricant (grease) and act as a safety guard.
