POWER GEARING SYSTEM FOR A WIND TURBINE

摘要

A power transmission system 10 of a wind turbine has a main shaft 16 configured to be driven by the rotor 6 and a support structure 60, a gearbox 25 having a gearbox housing 24,30 rigidly coupled to the support structure 60 and a planet carrier 26. A coupling member 50 connects the planet carrier 26 to the main shaft 16. The main shaft 16 is associated with a set of teeth 74 projecting radially outward, the planet carrier 24 is associated with a set of teeth projecting radially inward 76, the coupling member comprises a radially inward projecting set of teeth 78 engaging with the set of teeth 74 associated with the main shaft 16, and the coupling member further comprising a radially outward projecting set of teeth 79 engaging with the set of teeth 76 associated with the planet carrier 16.
