Purpose:

Torque Transmission:
It efficiently transfers the stepped-up rotational torque from the gearbox to the generator, enabling smooth electricity generation.

Misalignment Compensation:
The coupling accommodates radial, axial, and angular misalignments between shafts, preventing damaging stresses caused by dynamic operational factors.

Vibration & Shock Damping:
It acts as a buffer, absorbing and dampening vibrations and torque spikes from dynamic wind conditions, protecting sensitive drivetrain components.

Electrical Insulation:
The coupling provides electrical insulation to prevent stray currents from the generator from damaging gearbox bearings and gear teeth.

Overload Protection:
Some designs include features like torque limiters to prevent catastrophic drivetrain failure during extreme overloads.

Facilitates Installation & Maintenance:
Its flexible and often maintenance-free design simplifies installation and reduces upkeep in remote turbine environments.
