The flange coupling is classified as which type of mechanical coupling?

Flange couplings are classified as rigid mechanical couplings because they are designed to connect two shafts that must be aligned precisely and transmit torque without allowing for any misalignment or movement between the connected shafts. These couplings are typically made from materials such as steel or iron to ensure durability and strength.

In a rigid coupling, the shafts are fixed together, which ensures that they rotate in unison. This characteristic makes them ideal for applications where alignment can be maintained, and there is little to no relative motion between the shafts.

The nature of flange couplings means that they do not accommodate any angular misalignment or axial movement, emphasizing their classification as rigid. This distinction is crucial in applications where precision and reliability are essential, as any misalignment could lead to increased wear, vibration, and potential failure of the connected equipment.
