Flexible vs Rigid Couplings

1. Couplings Couplings are mechanical devices used to connect two rotating shafts for power transmission.

2. What is a Coupling? A coupling is a mechanical device used to connect two rotating shafts, allowing the transfer of torque and power from one shaft to another. It plays a vital role in ensuring smooth and efficient power transmission in various industrial applications. Rathi Couplings, a trusted name in the power transmission industry, offers a wide range of high-quality couplings designed to handle misalignment, absorb shocks, and reduce wear on machinery. Their precision-engineered products are used across industries such as manufacturing, power generation, mining, and more—helping businesses achieve reliable and long-lasting mechanical performance.

3. What is the Role of Couplings? Power Transmission Misalignment Compensation Efficiently transfers rotational force and torque between connected shafts, ensuring optimal energy delivery throughout mechanical systems. Accommodates angular, parallel, and axial misalignment between shafts, protecting equipment from premature wear and failure. Vibration Dampening Overload Protection Absorbs shock loads and reduces vibration transmission, extending component life and improving overall system reliability. Provides safe disconnection during overload conditions, preventing costly damage to motors, gearboxes, and connected machinery.

4. How It Works Couplings Couplings are mechanical devices used to connect two shafts together to transmit power and torque while accommodating some degree of misalignment or movement. They help in reducing shock loads, compensating for shaft misalignment, and protecting connected equipment from damage. Couplings come in various types—like rigid, flexible, and fluid—each designed for specific applications, ensuring smooth operation, efficiency, and longevity of machinery.

5. Types of Couplings Rigid Couplings Gear Couplings: consist of two hubs with external and internal gear teeth that mesh, allowing torque transmission with minimal backlash in tightly aligned shafts. Flange Couplings: use two flanges bolted together, creating a strong, rigid connection ideal for high-torque applications requiring accurate shaft alignment. Jaw Couplings: have interlocking jaws on two hubs connected by an elastomeric spider, providing a rigid connection that also absorbs slight shock but still requires good alignment. Flexible Couplings Fluid Couplings: Use a hydraulic fluid to transmit torque smoothly, providing slip protection and cushioning against shock loads. Disc Couplings: Utilize flexible metal disc packs to deliver zero-backlash precision, accommodating misalignment in high-speed applications. Jaw Couplings: Feature an elastomer insert that provides excellent vibration dampening and shock absorption while allowing slight misalignment.
