Torque Transmission

Flexible couplings are primarily used to transmit torque between two shafts while accommodating misalignments.

Vibration Damping

These couplings help in damping vibrations, ensuring smooth and quiet operation of machinery.

Shock Absorption

Flexible couplings absorb shock loads, protecting connected equipment from damage.

Compensation for Misalignment

They can compensate for angular, parallel, and axial misalignments between connected shafts.

Reduction of Maintenance

By reducing wear and tear on machinery, flexible couplings help in minimizing maintenance requirements and operational downtime.

What are the three types of coupling?

Rigid Couplings

Rigid couplings are used where precise shaft alignment is required. They do not allow for misalignment and are mainly used in applications where shafts are aligned perfectly.

Flexible Couplings

Flexible couplings can accommodate misalignments and are used in applications where flexibility and vibration damping are essential.

Fluid Couplings

Fluid couplings use hydraulic fluid to transmit torque and are commonly used in applications where smooth start-up and overload protection are necessary.

Selecting or Customizing the Right Elastic Coupling

Load Capacity

The load capacity of the coupling must be assessed to ensure it can handle the torque and forces applied during operation.

Environmental Conditions

Consider the environmental conditions such as temperature, humidity, and exposure to chemicals when selecting a coupling.

Misalignment Compensation

Determine the degree of misalignment that the coupling needs to accommodate to ensure optimal performance.

Material Selection

Choose materials that are compatible with the operational environment and provide the necessary durability and flexibility.

Cost and Availability

Evaluate the cost and availability of the coupling, ensuring it meets budgetary constraints and delivery timelines.
