Beam Coupling

Understanding Beam Couplings

Beam couplings achieve flexibility through one or more helical slots machined into a single piece of material. This allows the coupling to bend, accommodating misalignment between connected shafts while transmitting torque with high torsional stiffness. The absence of moving parts ensures inherent zero backlash.

Key Advantages:

• Zero Backlash: The single-piece design eliminates any play, crucial for precise motion control and positioning.
• Single Piece Construction: Simple, robust design with no assembly required and no parts to fail or wear independently.
• Maintenance-Free: Requires no lubrication or servicing throughout its operational life.
• Low Inertia: Lightweight design (especially Aluminium versions) results in low inertia, beneficial for dynamic applications.
• Misalignment Accommodation: Capable of handling moderate levels of angular, parallel, and axial shaft misalignment.

Considerations:

• Lower Torque Capacity: Generally suited for lower torque applications compared to disc or gear couplings.
• Torsional Stiffness: Can be less stiff than some other metallic coupling types, depending on the cut pattern and material.
• Fatigue Potential: Subject to fatigue failure if operated beyond its specified misalignment or torque limits.
