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.
