Elign Gear Couplings consists of hubs with multi crowned teeth at Flank, tip and chamfering on teeth.
Flanks of the teeth are crowned so that tooth thickness is greatest at that centre of the tooth.
Tips of teeth are crowned. The crowned tip contacts the root of internal gear teeth in the external sleeve, accurately piloting the sleeve with true concentric ball-and-socket action.
Gear case is of streamlined design, rugged in construction, made of close-grain cast iron.
Faces of the teeth adjacent to the tips are chamfered to eliminate interference with the sleeve tooth fillets.
