Gear Coupling

Understanding Gear Couplings

Gear couplings transmit torque through the meshing of external gear teeth on the hubs with internal gear teeth on the sleeve(s). The curvature (crowning) on the gear teeth allows the coupling to accommodate misalignment. Fully flexible (double engagement) types have two sleeves (or one continuous sleeve engaging two hubs) and accommodate all types of misalignment. Flex-rigid (single engagement) types have one geared hub and one rigid hub, primarily accommodating angular misalignment.

Key Advantages:

• High Torque Density: Can transmit significantly more torque than other flexible couplings of comparable size. Ideal as a high-torque-coupling.
• Excellent Misalignment Capability: Effectively handles substantial angular, parallel (fully flexible type), and axial misalignment.
• Robust Construction: Typically made from high-strength forged or alloy steel, suitable for harsh environments.
• Torsional Stiffness: Relatively high torsional stiffness, though less than disc couplings.

Considerations:

• Lubrication Required: Regular greasing or oil lubrication is essential to prevent wear on the gear teeth. Seals are critical to retain lubricant and exclude contaminants.
• Potential Backlash: Wear on the gear teeth over time can introduce backlash into the system.
