Blade setting mechanism for the rotor blades of a windmill.

摘要

Blade setting mechanism for rotor blades of a windmill. The mechanism comprises a spindle shaft which is coaxially arranged in a hollow rotor shaft, and setting means which are displaced by the rotation of the spindle shaft relative to the rotor shaft. On the one side the spindle shaft can be fixedly connected by means of an electro-magnetic clutch with the rotor shaft, on the other is connected to a stationary rotation motor. Using an auxiliary shaft the spindle shaft can optionally be driven with lower or higher speed and that of the rotor shaft.
