ABSTRACT:
Conventionally, a main shaft of the wind turbine apparatus has awkward such as heaviness or difficulties of assembling, since the length of the main shaft must be long to support a generator rotor. It is requested originally to light heaviness of a wind turbine apparatus, since it supports a wind wheel and a generator etc. on a tower at prescribed height. A hub29supported on the one side of the main shaft10, a generator rotor12supported on the other side of the main shaft10, the main shaft housing40and the generator housing20are combined, the generator rotor12having a backward opening is fixedly provided on the rear end of the main shaft10, the main shaft10and the generator rotor12are detachably fixed through the opening, and a rotational fitting (rod bearing33) for a pitch control shaft37is at least disposed at the rear space of the generator housing20.
