Flexible Couplings - Applications

Flexible couplings are utilized to transmit torque starting with one shaft then onto the next when the two shafts are marginally misaligned.

In simple words, it can be said Flexible couplings are used to transmit torque from one shaft to another when the two shafts are slightly misaligned.

In this example, the test fixture is using a torque transducer as a torque senor for measuring torque. In this example, the flexible couplings are used to connect the motor and torque sensor with the workpiece.

These two couplings need to minimize any misalignment error since the torque sensor needs to lay as flat as possible. They also need to protect the sensor from overloading.

Major characteristics of the flexible couplings are very low or zero backlashes, good torsion rigidity as good lateral, and angular misalignment capabilities making them suitable for various applications.

Applications:

At first, flexible couplings separate into two essential groups, metallic and elastomeric.

Metallic types utilize freely fitted parts that roll or slide against one another or, on the other hand, non-moving parts that bend to take up misalignment.

Elastomeric types, then again, gain flexibility from resilient, non-moving, elastic or plastic elements transmitting torque between metallic hubs.
