YL - flange coupling (GB / T 5843-86) ● flange coupling (also known as the flange coupling) using bolt connection flange (flange) disc coupling half, the two respectively with the key of the coupling half with the two shaft couplings, in order to achieve the two shaft couplings, transmission torque and motion. ● flange coupling structure is simple, easy fabrication, low cost, reliable work, assembly and disassembly, compared with simple maintenance, transmission torque larger, to ensure that the two axes has high accuracy, commonly used in the load smoothly , high-speed or drive high precision shaft drive. ● flange coupling does not have radial, axial and angular compensation performance, when used if you can not guarantee that the two axes are coupled to accuracy, it will reduce the life of the coupling, transmission accuracy, and the drive frequency, and causing vibration and noise. The GYD type (original the YLD-type) - flange coupling (GB / T 5843-86) ● flange coupling (also known as the flange coupling) is the use of bolts join two flanges (flange) disc half coupling, the two coupling halves, respectively, using the key and the two shaft couplings, in order to achieve the two shaft couplings, torque transmission and movement. ● flange coupling structure is simple, easy fabrication, low cost, reliable work, assembly and disassembly, compared with simple maintenance, transmission torque larger, to ensure that the two axes has high accuracy, commonly used in the load smoothly , high-speed or drive high precision shaft drive. ● flange coupling does not have radial, axial and angular compensation performance, when used if you can not guarantee that the two axes are coupled to accuracy, it will reduce the life of the coupling, transmission accuracy, and the drive frequency, and causing vibration and noise
