Nu-Teck manufactures straight tooth Gear Coupling and Tripple Crowned Teeth Gear Coupling.
Under the misalignment condition of two shafts of the equipments, the teeth contact in case of straight cut hub will be as minimum as shown in the fig No.1Under 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
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 angular misalignment ( ) is 1.1/2 deg. and in case of NU-TECK Triple Crowned tooth Gear Coupling the misalignment is 3.1/2 deg.
