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 to the two shafts with a key to realize the connection of the two shafts and transmit the torque. And sports.The flange coupling is simple in structure, convenient to manufacture, low in cost, reliable in operation, easy in assembly and disassembly and maintenance, and has a large transmission torque, which can ensure high centering accuracy of the two shafts. It is generally used for stable load. High-speed or high-precision shafting transmission.
Flange coupling is a rigid coupling. It connects two flanged half couplings to the two shafts with ordinary flat keys, and then connects the two half couplings into one body with bolts to transmit motion And torque.This kind of coupling has two main structural forms: ①The reaming hole uses bolts to realize the centering of the two shafts and the bolt rod to withstand extrusion and shear to transmit torque; ②Rely on a half coupling The shoulder is aligned with the groove on the other half coupling to be centered.The bolts connecting the two half-couplings can be ordinary bolts of grade A and B, and the torque is transmitted by the frictional moment of the joint surface of the two half-couplings.
Flange couplings are divided into three types: GY-basic type, GYS-centering tenon type, and GYH-centering ring type.
