Flexible coupling: gear coupling
Cross & Morse
Coupling types GFA and GFAS are designed for heavy industrial applications, providing a torsionally stiff connection of shafts which can accommodate angular and parallel misalignment and axial movement. The GFA gear coupling consists of two hardened steel hubs with external crowned and barrelled gear teeth, connected by a hardened steel sleeve with matching gear teeth. High torque capacity coupling for medium speed applications, up to 6,000 rpm. Torsionally stiff. Require good alignment for long service life. The GFAS gear coupling has only one hub with external teeth, which connects to a sleeve with integral hub, to reduce weight and inertia. This series provides a stiffer connection, particularly suited to cardan shaft applications.
Use Gear couplings:-
* For high torque reversing drives on Cranes, Rolling Mills
* For high shock load applications, Crushers, Rubber Mills
* Large Motor Gearbox connection
* Drives requiring torsional stiffness
