All About Gear Couplings
Gear couplings are popular form of flexible coupling in mechanical power transmission. Suitability to wide application areas, usability & easiness in installation has made them one of the most preferred types of mechanical power transmission couplings. Basically, they form a mechanical device that has high capacity of transmitting 'torque' between two connected shafts, which are not collinear. 1. Considered as torsionally rigid in performance, their basic design can be divided into two major types: 2. Full Flexible Type Semi Flexible type or Flexible-Rigid connection. A full flexible type coupling consists of two external gear hubs with finished bore & keyway, mounted on connecting shafts. Teeth of these hubs engage with internal teeth of a common, which forms a spline like joint for power transmission. A semi-flexible coupling primarily comprises of 2 halves, flexible & rigid. Rigidity on one end does not accommodate parallel displacement of shafts but sin
