Rigid coupling is a torsionally rigid coupling, even if it bears a load, there is no slewing backlash, and even when there is a deviation to produce a load, the rigid coupling still transmits torque rigidly.
Rigid couplings are divided into flange couplings, radial key flange couplings, sleeve couplings, shell couplings, and parallel shaft couplings. Flange couplings: use bolts to connect two halves of the coupling The flange of the shaft coupling is used to realize the coupling of the two shafts. The radial key flange coupling: the coupling sleeve that uses the radial key and the ordinary bolt to connect the two halves of the coupling. The coupling: the use of a common sleeve Couplings that couple two shafts in one way or another: Couplings that use two axially split housings to clamp in a certain way to achieve two-axis coupling Parallel shaft couplings: use The intermediate plate passes through the pin to realize the coupling of two parallel shafts.

Disadvantages: Flange couplings have high requirements on the neutrality of the two shafts. When there is relative displacement of the two shafts, it will cause additional loads in the machine and deteriorate the working condition. This is its main disadvantage. Advantages: However, due to the 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 centering is good. Flange couplings (also known as flange couplings) are bolted to two flange (flange) disc half couplings. The two half couplings are respectively connected to the two shafts with keys to achieve two shafts. Coupling, transmitting torque and motion. The flange coupling is simple in structure, convenient in manufacturing, low in cost, reliable in work, simple in assembly and disassembly, and maintenance, and has a large transmission torque, which can ensure high alignment accuracy of the two shafts. It is generally used for stable load. High-speed or high-accuracy shafting transmission is required. Flange couplings do not have radial, axial, and angular compensation performance. If the centering accuracy of the two 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. All bolts on the flange of the rigid coupling can be hinged bolts, or half of the bolts are ordinary bolts.
