YLD type 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 keys to achieve The two shafts are connected to transmit torque and movement. YL flange coupling can be made of gray cast iron or carbon steel, and cast steel or forged steel should be used for heavy loads or when the peripheral speed is greater than 30 m/s. The YL flange coupling has high requirements for the neutrality of the two shafts. When the two shafts have relative displacement, it will cause additional loads in the machine parts and worsen the working conditions.
YL type flange coupling has two main structural forms:
1. It is centered by matching the convex shoulder on one half coupling with the groove on the other half coupling.
2. Rely on reamed holes and bolts to achieve two-axis alignment and rely on bolt rods to bear extrusion and shear to transmit torque;
The bolts on the YLD (YL) flange coupling can be all bolts for reaming holes, or half of them are bolts for reaming holes, and the other half are ordinary bolts.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.There are two main structural forms of this coupling:
1. Rely on reamed holes and bolts to achieve two-axis alignment and rely on bolt rods to bear extrusion and shear to transmit torque;
2. It is centered by matching the convex shoulder on one half coupling with the groove on the other half coupling.The bolts connecting the two half-couplings can be grade B ordinary bolts, and the torque is transmitted by the frictional moment of the joint surface of the two half-couplings.
YL type flange coupling is abbreviated as "flange coupling", which 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 with bolts. The coupling is connected as a whole to transmit movement and torque.The bolts connecting the two half-couplings can be grade B ordinary bolts, and the torque is transmitted by the frictional moment of the joint surface of the two half-couplings.
