Full Flexible Gear Couplings

Under the misalignment condition of two shafts of the equipment, the teethcontact in case of straight cut hub will be as minimum as shown in the figure No. 1

Under heavy loads the ends of the hub teeth will get damaged resulting in the excessive play between hub & sleeve. And, therefore, the reduction in life of coupling.

NU-TECK TRIPLE-CROWNED TEETH
The triple crowned teeth hub is manufactured on a fully automatic hobbing machine with built in crowing attachment which is controlled by hydraulic & electronic systems. Under the misalignment condition of two shafts on the equipment, due to the curvature on teeth flank the contact area is much more and therefore, there is increase in life of coupling.

MISALIGNMENT DETAILS : In case of straight tooth gear coupling the maximum allowable anguler misalignment (μ) is 1.1/2 deg. and in case of NUTECK Triple Crowned tooth Gear Coupling the misalignment is 7.1/2 deg.
