Understanding of flange coupling: Flange coupling is a mechanical manufacturer standardized production of transmission products, we all in the choice of coupling transmission parts at the beginning of the stage, we need to understand the standard, machine industry standard of coupling transmission products in line with the need to use the type. If this type of coupling cannot be found, you can contact the manufacturer to design the coupling product by yourself. When the shaft and shaft to be connected to convey power, generally useful pulley or gear to do connection, but if the two shafts to be in a straight line and require constant speed rotation, you need to use coupling to connect. The main structure of flange coupling: For the flange coupling transmission parts, machinery manufacturers all year round production, our manufacturers in the process of production constantly improve the production technology, for every user to provide reliable quality coupling transmission parts. The coupling transmission parts have two main structural forms in the process of production: (1) by reaming holes with bolts to achieve two shaft alignment and by the bolt rod to bear the 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 the two half couplings can be ordinary bolts, and the torque is transmitted by the friction torque of the joint surface of the two half couplings. To sum up: Flange coupling because of the processing precision and shaft heat expansion or operation of the shaft bending force, if the coupling transmission parts between the concentricity change, so the flexible coupling as a bridge to maintain the power transmission between the two shafts, and to absorb the radial, Angle and axial deviation between the two shafts, and then extend the life of machinery, improve the quality of machinery.
