YL - flange coupling (GB / T 5843-86) ● flange coupling (also known as the flange coupling) is the use of bolt connection flange (flange) disc coupling half, two half coupling key with the shaft connected to the two shaft connected to transmit torque and motion. Flange coupling structure is simple, easy to manufacture, low cost, reliable, easy assembly and disassembly, maintenance than simple transfer torque, to ensure two-axis has a high accuracy, commonly used in the load stable , high-speed or high precision drive shaft drive. Flange coupling does not have to compensate for the performance radial, axial and angular, use if you can not guarantee that connected two-axis accuracy, will reduce the coupling life, driving accuracy and transmission frequency and cause vibration and noise.
