Drive system for positioning cabin of large wind generator tower toward the wind

摘要

The cabin (12) is turned and positioned about the vertical axis of the tower (10), using a gear ring (14) fastened to the tower and two or more mutually-angled drive cylinders (16, 18). One section (16a, 18a) of each cylinder is connected to and pivots about a vertical axis fixed to the cabin. The other sections (16b, 18b) are connected through pivots to teeth engaging the gear ring, which transmit the drive force.
