Abstract

The present invention relates to a flexible mechanical power/torque transmitting means for wind turbine. The flexible torque transmitting means allows torque as input at one member of turbine and transfer's to another member of turbine. By considering rotor assembly as one member of the wind turbine, it acts as torque transmitting member during generation mode and torque receiving member during motoring mode. This configuration of flexible torque transmitting means eliminates stress on both members, short coming of rigid connecting member, shifts centre of gravity of turbine to a lower point, structurally isolate the generators, transmit torque alone flexible means from rotor assembly to driving member while power generation, reduce stress and fatigue. The torque transmitting member can be connected with rotor of generator or driving means of plurality of generator or combination thereof.
