Why Gear Coupling ?


A Gear Coupling is used to join two rotating shafts for efficient transmission of mechanical power. Although the shafts are accurately aligned at the time of installation, it is likely that during the operation the alignment may get disturbed due to setting of foundation, thermal expansion, shaft deflection, wearing out of other parts, improper maintenance and many more reasons. Due to this unavoidable misalignment occurring during the operation a gear coulping provides a better solution to compensate or minimise the effect of misalignment.


The gear Couplings are therefore idealy suited for wide range of application in the entire field of drive technology.


Misalignment


The main function of any Gear coupling is not only to connect two rotating shafts but also to accommodate mis-alignments of the connecting shafts ELIGN Gear coupling accommodates the following three types of misalignment.

 

A. RADIAL

When axes of connected shafts are parallel but not in the same straight line

B. ANGULAR

When axes of connected shafts intersect at center point of coupling but not in the same straight line.  

C. COMBINED RADIAL & ANGULAR When the axes of connected shafts do not intersect at point of coupling and are not parallel. 


Besides above three types of misalignment, the ELIGN Gear coupling also permits axial movement of the shaft.

 

CAUTION :


Normally permissible angular mis-alignment of ELIGN gear coupling is 0.75 for each half. However, it does not mean that the misalignment should be permitted to this limit from the initial installation. Since in case of misalignment occurring during operation the Elign gear coupling takes care of it without undue damage to the connected equipment, however the coupling’s life may reduce due to relative motion between hub teeth and housing teeth causing fast wearing out of teeth. It is therefore extremely important to align the interconnecting shafts precisily during initial installation.

Fenner Curved Tooth Flexible Gear Couplings are 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.
