Curved Tooth Flexible Gear Couplings
AGNEE Gear Couplings are distinguished by their mechanical flexibility
and compensation of Angular, Parallel and Axial misalignments of the
connected shafts. Gear Couplings are made for extensive use in Metal
Rolling Mills, Paper Machinery, Cranes, Dredgers, Rubber and Plastic
Industries, Cement Plants, Conveyors and Elevators, Compressors, Fans
and Blowers, Screens and other general industries. Flexible Gear
Couplings basically consist of two hubs, with crowned external teeth and
two outer sleeves with internal spur teeth.

FEATURES: Gear Hubs and the outer sleeves are manufactured from carbon
steel and are hardened to the required degree. They are machined to fine
tolerances for proper meshing of the gears as well as for
inter-changeability.
HUBS : The teeth of Gear Hubs are crowned and are generated by involute
system. The amount of crowning and backlash values are so chosen as to
ensure the best results in torque transmission, greater flexibility and
smooth operations.
SLEEVES : The internal teeth of the sleeves are produced in gear shaper
ensuring the correct profile. These teeth are also generated by involute
system.
The coupling sleeves are joined together with high tensile steel (class
8.8 IS : 1367) fitted bolts.
'O' RINGS : The setting of special 'O' Rings at the ends of coupling
hubs prevents leakage of lubricants and entry of dust. The 'O' rings can
also withstand high degree of O temperature upto 120 C.
POWER RATINGS :The normal power ratings are given in the Table. For
selection of the correct size of couplings, proper service factor
depending on the type of machines and the peak load should be
considered.
SERVICE FACTOR :Generally, for medium duty use a service factor of 1.5.
For heavy duty use a factor of 2 and for extra heavy duty a factor of 3
should be used. For special applications please contact AGNEE with full
details.
LUBRICATION :The coupling must be filled with grease or oil. It is
recommended to use grease where the maximum temperature is within 80
degree C and for temperature above 80 degree C, oil should be used.
When using grease it is suggested to fill the coupling completely
with Lithium based grease with EP additives (NLGI-No.1 consistency).
When the coupling is to be filled with oil, fill half the coupling with
EP Gear Oil.
RECOMMENDATION FOR GREASE & OIL:
Grease : Indian Oil - Servogem - EP 1 or equivalent.
Oil : Indian Oil - Servomesh SP 680 or equivalent.

MISALIGNMENT: The crowing of the teeth
allows the coupling to withstand parallel misalignment upto a
maximum of 10.25 mm and angular misalignment upto a maximum of ±
1.5 per gear mesh. The coupling can also absorb axial displacement
of the shafts upto a maximum of ± 3 mm. |

FOR SELECTION OF THE COUPLINGS, THE FOLLOWING DETAILS ARE
REQUIRED :
1. Type of driven machine.
2. Power absorbed by the driven machine and Peak load.
3. Speed and Diameter of the connecting shafts space available for
accommodating the coupling.
4. Maximum misalignment to be compensated.
5. Surrounding temperature.
6. Any other special feature of the drive.
Example : A gear couplings is required to transmit 250 KW from an
Electric Motor running at 730 rev/min to a Pulper Machine.
Considering the peak load as 180% of full load, the Motor shaft as
100 mm and the Pulper shaft as 110 mm, select a suitable gear
coupling.
a) Service factor : 2 (for heavy duty application)
b) Peak load : 180% of full load.
c) Design power : 250 x 180/100 x 2 = 900 KW
d) Power to be transmitted at 100 rev/min : 900 x 100 / 730 =
123.3 KW
e) Coupling size : By referring to the Table coupling size NGC 5,
has got a rating of 150 KW at 100 rev/min which exceeds the
required power of 123.3KW. The bore range is 60 mm to 110 mm.
Hence, size AGC 5 is selected for the application.
