Coupling

Flexible coupling is a mechanical device used to connect two rotating shafts while accommodating misalignment (angular, parallel, or axial), absorbing shock/vibration, and transmitting torque between them. It allows for angular, radial, or axial deviations that may occur due to manufacturing tolerances, installation errors, or operational deflections, preventing excessive stress on connected components. Unlike rigid couplings, flexible couplings incorporate elastic elements (such as elastomers, metal flexures, or springs) or articulated designs to absorb vibrations, dampen shocks, and ensure smooth power transmission.

 

Various Couplings Types Available:

• Jaw Couplings(e.g., Lovejoy): Elastic spider for vibration damping.
• Beam Couplings(helical cut): High flexibility for precision motion.
• Gear Couplings: High torque with angular/parallel flexibility.
• Oldham Couplings: Accommodates large parallel misalignment.
• Torsional Spring Couplings: Coil springs between hubs to absorb shocks and provide flexibility.

 

Metallic Materials:

• Steel: High strength and torque capacity. Requires lubrication; prone to corrosion if uncoated.
• Stainless steel: Corrosion-resistant for harsh environments (food, marine, chemical industries).
• Aluminum: Lightweight for high-speed applications. Lower torque capacity than steel.

 

Elastomeric Material:

• Polyurethane (PU):Good shock absorption and wear resistance. Limited temperature range (-30°C to +90°C).

 

Key Features:

• Torque Transmission: Efficiently transfers rotational power while handling peak torque and cyclic loads.
• Compact and lightweight: Space-saving designs suitable for constrained installations.
• Speed and temperature adaptability: Handles high RPMs (balanced designs) and operates across a wide temperature range.
• Vibration and shock damping: Absorbs torsional vibrations and dampens impact loads (e.g., elastomeric inserts in jaw couplings). Improves system stability and longevity.
• Misalignment Compensation: Accommodates angular, parallel, and axial misalignment between connected shafts. Reduces stress on bearings and machinery.
• Safety Features:  Designed to fail safely (e.g., torque-limiting mechanisms) in overload situations, preventing damage to critical components.

 

Simple Structure:

Easy to install, easy to assemble and disassemble. Simplified assembly and disassembly reduce downtime and labor costs.

 

Application Scope:

Pumps, compressors, conveyors, servo motors, and wind turbines where flexibility and reliability are critical.
