Rigid coupling purchase instructions

Rigid coupling is a big category of coupling, previously known as fixed rigid coupling, is composed of rigid force transfer parts, the connection between the relative motion, so does not have the ability to compensate for the two axis relative offset, only applicable to be connected to the two axes in the installation can be strictly, do not produce two axes relative offset occasions, flange coupling elastic components, It does not have the function of damping and buffering, and is generally only suitable for the working conditions of stable load and no impact vibration.

Including flange coupling, radial key flange coupling, open shaft coupling, shell coupling, sleeve coupling, etc.

The rigid coupling is generally simple in structure and low in manufacturing cost. When choosing rigid coupling, the error of the axis of the connected two axes should be minimized. In order to reduce the influence 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 the use of bolts to connect two flanges (flanges) disc half coupling

There are two main forms of rigid coupling construction:

(1) By reaming holes with bolts to achieve two-axis neutralization by the bolt rod to bear extrusion and shear to transfer torque;
The convex shoulder on one half coupling is matched with the groove on the other half coupling. The bolts connecting two half couplings may be class A and class B ordinary bolts. Torque is transmitted by the friction torque of the joint surfaces of the two half couplings. The material of rigid coupling can be gray cast iron or carbon steel, and cast or forged steel is used when the heavy load is applied or the circumference velocity is greater than 30 m/s.
