What is a Coupler?
A coupler is a device used to connect two shafts at their ends to circulate power. The primary purpose of couplers is to join two pieces of rotating equipment. The coupler is a parallel thread mechanical splicing system designed for the connection of concrete reinforcing bars. In this method, two fibres are aligned and held together within a tube and the index matching gel creates the bond. Another mechanical splice method is V-groove.
Why do we use Couplers?
- It reduces the material cost.
- It saves time for designers.
- No calculation for lapping reinforcements.
- It improves structural durability.
- Reduce the construction time.
- Reduce the reinforcement choking.
- No reinforcement cranks.
- It is technically more advance.
- Improves the quality of construction work.
Disadvantages of Mechanical Couplers →
- It is unable to absorb shocks or vibrations during power delivery.
- It cannot tolerate any misalignment in the axis of the shafts.
- Difficult to assemble as the sleeve has to be shifted over a shaft or shaft ends.
- Technical knowledge is required on the subject.
- Poor quality joints may lead to structural failure.
- High attention is mandatory with proper supervision of the work.
Types of Couplings →
Coupling is mainly divided into two categories:
- Material Flexing Couplings
- Mechanical Flexing Couplings
