What is difference between rigid and flexible coupling?
Rigid couplings provide a rigid connection; the two shafts are firmly connected, and the coupling allows for a smooth transmission of torque throughout the system. Flexible couplings create flexible connections, and the components can lose some of the torque power through the interaction.
Why are rigid couplings used?
Rigid couplings are designed to connect two shafts together so that no relative motion occurs between them (see Fig. 4.16). Rigid couplings are suitable when precise alignment of two shafts is required. If significant radial or axial misalignment occurs, high stresses may result, which can lead to early failure.
What are the two types of couplings?
Following are the different types of coupling:
- Rigid Coupling.
- Sleeve or muff coupling.
- Clamp or split-muff or compression coupling, and.
- Flange coupling.
- Flexible coupling.
- Bushed pin-type coupling,
- Universal coupling.
- Oldham coupling.
How many types of couplings are there?
However there are two main types of couplings (Fig 1) which are (i) rigid couplings, and (ii) flexible couplings. Rigid couplings are used for shafts having no misalignment. Since these couplings cannot absorb any misalignment the shafts to be connected by a rigid coupling must have good lateral and angular alignment.

What is classification of coupling?
Couplings fall into two main categories: Material Flexing and Mechanical Flexing. The material flexible types obtain their flexibility from stretching or compressing a resilient material, such as rubber, or from the flexing of thin metallic discs or grid.
Why are rigid couplings used *?
Rigid couplings are used mainly on low speed or low torque applications where the shafts are an identical size and are not subject to misalignment. Applications which use rigid shaft couplings include: Conveyors. Food processing applications.
What is coupling and different types of coupling?
Types and features of couplings (shaft fittings)
