What Are The Types Of Coupling?

A chain coupling is a type of flexible coupling that uses interlocking chains to transmit torque between two shafts. It consists of two sprockets with an interconnected roller chain, allowing for slight misalignment and providing mechanical flexibility. Chain couplings are commonly used in applications requiring high torque transmission and the ability to accommodate shock loads and vibrations.

Jaw Coupling:

Jaw couplings are flexible couplings that consist of two hubs connected by an elastomeric element with curved jaws. The hubs have curved slots that interlock with the jaws of the elastomeric element, providing flexibility and torque transmission. Jaw couplings are known for their simplicity, compact design, and ability to dampen vibrations. They are widely used in various industrial applications.

FCL Coupling:

The FCL (Flexible Coupling Inc.) coupling, also known as a flexible control or floating shaft coupling, is a type of flexible coupling that can transmit torque between two shafts while allowing for angular misalignment. It uses a unique membrane design that provides flexibility and compensates for shaft misalignment. FCI couplings are commonly used in applications such as marine propulsion systems and power generation.

NM Coupling:

NM couplings, also known as Lovejoy couplings or jaw couplings, are flexible couplings that use elastomeric spider inserts with curved jaws to transmit torque between two shafts. They provide flexibility and vibration damping. NM couplings are widely used in power transmission applications, such as pumps, conveyors, and compressors.

MH Coupling:

MH couplings, also known as Martin Flex Couplings or three-piece couplings, are flexible couplings that consist of two hubs connected by a flexible center element. The center element can be made of neoprene, urethane, or other elastomeric materials. MH couplings provide torsional flexibility and are used in applications where misalignment, vibration, and shock absorption are factors.

HRC Coupling:

HRC (Highly Resilient Coupling) couplings, also known as elastomeric couplings or tire couplings, are flexible couplings that utilize a rubber tire-like element to transmit torque between two shafts. The tire element is sandwiched between two hubs, and torque is transmitted through the compression of the elastomeric material. HRC couplings provide high torque capacity, shock absorption, and flexibility. They are commonly used in various industries, including mining, agriculture, and automotive applications.
