The gearbox and the generator are connected by a flexible shaft. During the operation of the fan, the coupling compensates for the two parallelism deviations and angle errors.In order to reduce the transmission vibration, the coupling needs to have vibration and damping. In order to avoid torsional vibration in the case of deviation, the coupling must also have considerable rigidity.
The coupling must have an impedance greater than or equal to 100M and withstand a voltage of 2KV, which will prevent parasitic current from flowing from the generator rotor to the gear shaft or gearbox through the coupling, which may bring great harm to the gearbox.
The coupling has good axial and angular deviation compensation capabilities, can reach the given maximum compensation value at the same time, and can effectively reduce vibration and noise.
