Rigid coupling is composed of rigid force transmission parts, and the connecting parts cannot move relative to each other. Therefore, it does not have the ability to compensate for the relative deviation of the two axes. It is only suitable for the strict alignment of the connected two shafts during installation. When there is no relative deviation between the two shafts, the flange coupling has no elastic elements, and does not have the function of damping and buffering. Generally, it is only suitable for working conditions with stable load and no shock and vibration.
Rigid couplings were also called fixed rigid couplings in the past, including flange couplings, radial key flange couplings, open shaft couplings, clamp couplings, sleeve couplings Wait.Rigid couplings are generally simple in structure and low in manufacturing cost.When selecting a rigid coupling, the axis alignment error of the connected two shafts should be minimized. In order to reduce the impact of additional load on the coupling, the distance between the coupling and the bearing should be minimized.Flange coupling (also known as flange coupling) is a half-coupling that connects two flanges (flanges) with bolts.
Rigid couplings have two main structural forms: ①rely on reamed holes and bolts to realize the two-axis alignment and rely on the bolt rod to bear extrusion and shear to transmit torque; ②rely on the convex half of the coupling The shoulder is centered by matching the groove on the other half coupling.The bolts connecting the two half-couplings can be ordinary bolts of grade A and B, and the torque is transmitted by the frictional moment of the joint surface of the two half-couplings.
