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
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.
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
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
