Flexible Couplings

by Smriti G. Technical Consultant

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

Flexible couplings can oblige fluctuating degrees of misalignment up to 3° and some parallel misalignment. Likewise, they can also be utilized for vibration damping or noise reduction.

A coupling intended to permit a constrained precise movement between the axis of two waveguides.

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.
