Wind screw for converting kinetic energy of wind into mechanical rotary motion for driving electric generators by wind energy plants or other rotary drives, has rotor shaft rotating around longitudinal axis

摘要

The wind screw (1) has a rotor shaft (2) rotating around longitudinal axis, where a shell-type element is connected to the rotor shaft in torque-proof manner. The wind screw consists of three one-piece shell-type elements (3), where two longitudinally offset driver elements (6) are inserted in a connecting area. The shell-type elements consist of aluminum plate.
