Disc Coupling

Understanding Disc Couplings

Disc couplings are a type of flexible shaft coupling that transmits torque via one or more thin metal disc packs bolted between driving and driven hubs. The flexibility of these discs allows the coupling to accommodate angular, parallel (with double disc pack designs), and axial misalignment between connected shafts.

Key Advantages:

• Zero Backlash: The metallic disc packs provide a backlash-free connection, essential for precise motion control applications like servo systems (ideal as a servo-coupling).
• High Torsional Stiffness: Disc couplings offer high resistance to twisting, ensuring accurate torque transmission with minimal angular wind-up. This makes them a torsionally-stiff-coupling choice.
• High Speed Capability: Their balanced, all-metal construction allows operation at high rotational speeds without significant vibration.
• Misalignment Accommodation: Effectively compensates for angular, axial, and (with double disc packs) parallel shaft misalignments.
• Maintenance-Free: Require no lubrication and have no wearing parts under normal operating conditions.
• Temperature Resistance: All-metal construction generally allows for operation over a wider temperature range compared to couplings with elastomeric elements.

Common Configurations:

• Single Disc Pack: Accommodates angular and axial misalignment.
• Double Disc Pack (with Spacer): Accommodates angular, axial, AND parallel misalignment. The spacer length can be customized.
