Oldham coupling

grabcad

Oldham couplings consist of two aluminum hubs press-fitted onto a central disk. The slots on this disk mesh with the drive tenons on the hubs to transmit torque. In operation, the center disk glides along the tenons of each hub, which are positioned at 90° angles, for efficient torque transfer. These couplings can handle slight angular and axial misalignment but excel in applications with parallel misalignment issues.
