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 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.
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 & electronic system.
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.
DRIVES & DRIVES Roller chain Flexible Couplings are compact, all steel, long lasting flexible couplings, capable of transmitting relatively high torques with minimum of space consumption. Consequently, they provide a most economical means of positive transmission of power from one shaft to another.
The simple design and construction of these couplings make them extremely easy to install and disconnect, providing additional economy of operation.
The sprockets are identical in construction, thus providing a balanced unit in operation and reducing effects of vibration. In addition, the flexibility of roller chain plus clearance between the chain rollers and sprocket teeth allow for slight mis alignment and shaft end float.
Stock Couplings sizes will usually meet most power transmission requirements. However when necessary special couplings can be furnished on a made to order basis to suit a particular application. In such cases, complete information should be given when requesting a recommendation or quotation.This includes horsepower and RPM requirements, hub dimensions, bore and key way sizes, and general operating conditions.
