Know Everything about Gear Couplings

In mechanical power transmission gear coupling is a popular form of flexible coupling. What has made them one of the most preferred types of mechanical power transmission couplings is their suitability to a wide application like usability, areas & easiness in installation. Basically, between two connected shafts, they form a mechanical device that has a high capacity of transmitting 'torque', which is not collinear.

In performance they are considered as torsional rigid, their basic design can be divided into two major types:

Two external gear hubs are present in a fully flexible type coupling usually with finished bore & keyway mounted on connecting shafts. With internal teeth of common teeth are engaged in these hubs, which form a spline-like joint for power transmission.

2 halves, rigid and flexible are therein a semi-flexible coupling primarily. One end rigidity does not accommodate the parallel displacement of shafts but since it has flexible members; it surely does accommodate angular misalignment. This type of coupling is primarily employed in floating shaft applications.

In finished bore usually, a gear coupling from gear coupling supplier is supplied & installed & keyway conditions with specified dimensions against the requirement of the application.

What makes them suitable for a wide range of mechanical power transmission applications is the flexibility to absorb misalignment between 2 shafts, torsional rigidity, ease in installation & maintenance & most importantly high torque transmission capacity at low vibrations.

In design gear, teeth of the coupling is crowned which gives you the scope for absorbing angular misalignment while the scope for adjusting the linear misalignment is provided by the backlash between the mating teeth, which in turn makes the join, vibration-free during rotation.

Seals, machines, bearings, and shafts are therefore not subjected to the additional forces as large axial moments are avoided, sometimes of considerable magnitude.

There is extensive use of the gear couplings from gear coupling manufacturer in majority application areas such as heavy gearboxes, transmission drives, engines, fluid couplings similar where high torque transmission capacity along with torsional rigidity is required.
