Couplings are essential components in mechanical systems, facilitating the transmission of torque between shafts while accommodating misalignments and reducing vibrations. Rathi Group, a leading manufacturer in India, offers a comprehensive range of couplings tailored to diverse industrial applications. This article delves into the major types of couplings, highlighting their features and applications.​

Types of Couplings
Couplings are broadly categorized into two main types:​

Material Flexing Couplings: These couplings derive flexibility from the deformation of a resilient material, such as rubber or thin metallic discs. They typically do not require lubrication, except for specific types like grid couplings.​

Material Flexing Couplings
Jaw Couplings
Jaw couplings transmit torque through an elastomeric element positioned between two interlocking jaws. They are designed to accommodate misalignments and dampen vibrations, making them suitable for low-torque, general-purpose applications.​

Sleeve Couplings
Sleeve couplings consist of an elastomeric insert with splines that mate with corresponding hub splines. They handle moderate misalignments and provide torsional damping, ideal for low to medium torque applications.​

Tyre Couplings
Tyre couplings feature an elastic element connected to two hubs, transmitting torque in shear. They offer high misalignment capacity and are easy to assemble without moving connected equipment. These couplings are suitable for moderate to high-speed operations.​

Disc Couplings
Disc couplings transmit torque through flexing disc elements arranged in a pack. They accommodate angular, parallel, and axial misalignments, providing a zero-backlash design suitable for high-speed applications.​

Diaphragm Couplings
Diaphragm couplings utilize one or more flexible diaphragms to transmit torque. They accommodate angular, parallel, and high axial misalignments, making them ideal for high-torque, high-speed applications.​

Gear Couplings
Gear couplings consist of two hubs with external gear teeth that mesh with internal teeth of flanged sleeves. They transmit high torque in a compact design and accommodate angular and axial misalignments through the rocking and sliding of gear teeth. Proper lubrication is essential for their longevity.​
