Flange Couplings

GY type flange coupling is a rigid coupling, which uses two flange half couplings to connect two shafts with ordinary flat keys, and then connect the two half couplings with bolts to transmit motion and torque.

There are two main types of such coupling structures:

① Relying on the hinge hole with bolt to achieve the centering of the two shafts, and the torque is transmitted through the extrusion and shearing of the bolt rod;

② Align the shoulder of one coupling half with the groove on the other coupling half. The bolts connecting the two half-couplings can use ordinary A- and B-grade bolts, and the torque is transmitted through the frictional moment on the surfaces of the two half-couplings.
