Description

Hydraulic couplings consist of two-bladed wheels that face each other, but that is not in physical contact. The pump wheel, or driving turbine, is connected to the driving machine. The turbine wheel is connected to the driven machine.

Power is transmitted hydraulically in a wear-free manner. The higher the input speed, the greater the amount of mechanical energy transmitted from the blades on the pump wheel to the blades on the turbine wheel.

With fluid couplings, the only connecting element between the two-bladed wheels is the fluid in the working circuit.

During machine startup, the amount of fluid in the coupling can be varied to control the machine startup behavior and the amount of power transmitted. By dampening torsional vibration and driveline shock, hydrodynamic devices can help extend equipment life.

Changing the fill level in fluid couplings also allows the speed of the driven machine to be controlled. Additionally, hydrodynamic couplings protect the drive and the machine against damaging torque spikes. If necessary, the slip can reach 100%, meaning that the motor can continue to run in a stable machine range.

Characteristic

1.Used to connect shafts of units that are manufactured separately such as a motor and generator.
2.For the misalignment of the shafts.
3.For mechanical flexibility.
4.Absorbs the transmission of shock loads from one shaft to another shaft.
5.Protection against overloads.
