Flexible couplings are designed to transmit torque from one shaft to another. This is accomplished while compensating for some radial, axial and angular misalignment. They can accommodate varying degrees of angular misalignment and some parallel misalignment. In addition, flexible couplings can also be used for vibration damping or noise reduction. Flexible couplings are designed to transmit torque from one shaft to another. This is accomplished while compensating for some radial, axial and angular misalignment. They can accommodate up to a few degrees of angular misalignment and some parallel misalignment.
