YL type flange coupling

description: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 shafts are connected as a whole to transmit movement and torque.

Detailed introduction:

YL type flange couplingReferred to as flange coupling, it 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 a whole with bolts. Transfer movement and torque.The bolts connecting the two half couplings can be used with ordinary bolts of grade B, and the torque is transmitted by the frictional moment of the joint surface of the two half couplings.

Flange couplings have high requirements for the neutrality of the two shafts. When the two shafts have relative displacement, they will cause additional load in the machine parts and worsen the working conditions. This is its main disadvantage.However, due to its simple structure, low cost, and large torque transmission, it is often used when the speed is low, there is no impact, the shaft is rigid, and the neutrality is good.

YL type flange coupling has two main structural forms:

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.

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.
