Flexible Gear Couplings


Flexible Gear Coupling 01 Flexible Gear Coupling 02 Flexible Gear Couplings 03

Flexible Gear Couplings Is the result of many years of experience in the field of Mechanical Power Transmission. These Gear Couplings are distinguished by their mechanical flexibility and compensation of Angular, Parallel and Axial misalignments of the connected shafts. They 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. 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 generated to ensure correct profile. The coupling sleeves are joined together with high tensile steel bolts (class 8.8 IS: 1367) fitted using a gasket in between them.

'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 temperature up to 120 C O

SEAL CARRIERS :
Seal carriers have been provided for sizes from FGC 11 to FGC 19 facilitate inspection and replacement of 'O' rings without disturbing the alignment.

POWERRATINGS :
SERVICEFACTOR - 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. 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

LUBRICATION :
The coupling must be filled with grease or oil. It is recommended to use grease where the maximum temperature is within 80 C and for temperature above 80 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.1consistency). When the coupling is to be filled with oil, fill half the coupling with EP Gear Oil.

Custom built Gear Spacer Couplings and Torsion Shaft Gear Couplings are also manufactured & supplied as per requirements. Please contact with all details.
