Oldham Couplings are a 3 piece design comprising of two aluminium hubs press fit onto a centre disk. Torque transmission is accomplished by mating the slots on the centre disk to the drive tenons on the hubs. During operation, the centre disk slides on the tenons of each hub (which are oriented at 90° apart) to transmit torque. While the couplings accommodate a small amount of angular and axial misalignment, they are especially useful in applications with parallel misalignment.
