Applications
 
 
 
Under the misalignment condition of two shafts of the equipment, the teeth contact 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 and sleeve. And, therefore, the reduction in life of coupling. GREAVES TRIPLE-CROWNED TEETH The triple crowned teeth hub is manufactured on a fully automatic hobbing machine with built in crowning attachment which is controlled by hydraulic and electronic systems.
Due to misalignment condition the curvature of 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 GREAVES Triple Crowned Tooth Gear Coupling the misalignment is 7.1/2 deg.
