Rigid coupling, as the name implies, is actually a torsionally rigid coupling. Even when it is under load, there is no backlash. Even when the load is caused by deviation, the rigid coupling still transmits torque rigidly.
Disadvantages: Flange couplings have high requirements for the neutrality of the two shafts. When the two shafts have relative displacement, they will cause additional loads in the machine parts and worsen the working conditions. This is its main disadvantage.
Advantages: However, due to its simple structure, low cost, and large torque transmission, it is often used when the speed is low, there is no impact, the rigidity of the shaft is large, and the neutrality is good.Flange coupling (also known as flange coupling) is the use of bolts to connect two flange (flange) disc type half couplings. The two half couplings are respectively connected with two shafts by keys to realize two shafts. Connect, transmit torque and movement.Flange coupling has simple structure, convenient manufacture, low cost, reliable work, easy assembly and disassembly, and maintenance, and large transmission torque can ensure high centering accuracy of the two shafts. It is generally used for stable load. High-speed or high-precision shafting transmission.Flange couplings do not have radial, axial and angular compensation performance. If the centering accuracy of the two connected shafts cannot be guaranteed during use, it will reduce the service life, transmission accuracy and transmission efficiency of the coupling, and cause vibration And noise.The bolts on the flange of the rigid coupling can be all bolts for reaming holes, or half of them are bolts for reaming holes, and the other half are ordinary bolts.
