Beam Coupling

Understanding Beam Couplings

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

Key Advantages:

• Zero Backlash: The single-piece design eliminates any play or backlash, 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 & No Lubrication: Requires no maintenance or lubrication throughout its service 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.
• Cost-Effective Solution: Offers a good balance of performance and cost for suitable applications.

Considerations:

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