CENTRIFUGAL REGULATOR OF WINDWHEEL ANGLE OF BLADE Russian patent published in 2013 - IPC F03D7/02 

FIELD: power engineering.

SUBSTANCE: centrifugal regulator of a windwheel angle of blade comprises centrifugal mechanisms of working and reversible modes, comprising centrifugal weights and springs of working and reversible modes, providing for the possibility of their serial connection into operation. The regulator is installed on bearing plates that form a windwheel hub, between which there are windwheel blades in rotary bushings, and is equipped with a unit of synchronisation of angles of blades and transfer of motion from blades to centrifugal mechanisms of working and reversible modes, installed between bearing plates with the possibility of displacement relative to them. On one of the plates there is a spring of the working mode and a fixed body of the centrifugal mechanism of reversible mode so that the spring of the reversible mode covers the spring of the centrifugal mechanism of the working mode. Centrifugal weights are arranged along the circumference that is concentric with the longitudinal axis of the regulator and are connected with the movable casing of the centrifugal mechanism of the reversible mode with provision of its action at the unit of synchronisation and transfer of motion from the blades to the centrifugal mechanisms of the working and reversible modes.

EFFECT: increased reliability and increase of its resource with reduction of requirement to precision of units and parts manufacturing.
