Abstract

863,046. Wind motors. ROTAX Ltd. Oct. 2, 1959 [July 23, 1958], No. 23651/58. Class 110 (3). A wind motor for driving an alternating electric current generator having a plurality of radial blades 10 angularly adjustable about their radial axes comprises in combination with a rotor-driven spindle 20, a differential mechanism 22, 27, 24 interconnecting the spindle with a surrounding hollow spindle 25 having a gear 26 formed thereon or secured thereto, at least one non-rotatable and axially movable screw 37, a rotatable nut 36 mounted on the screw, gearing 34, 35 driven by the hollow spindle 25 for rotating the nut, an axially movable member 19 operable by axial movement of the screw 37 for imparting angular regulating movements to the rotor blades 10, a friction clutch 23, 30, 31 for controlling the action of the differential mechanism 22, 27, 24 on the hollow spindle 25 and speed-responsive centrifugal means 44 for controlling the clutch so that variations of the air speed or the load are accompanied by compensatory angular adjustment of the rotor blades. To counteract the centrifugal forces on the blades, the stub axle 12 of each blade carries a blade actuating pin 16 having a partspherical portion 17 which bears against an abutment 15. Three non-rotatable screws 37 may be provided and each screw carries two adjustable nuts 39 situated on either side of a flange 40 connected to a sleeve 29 forming part of the friction clutch. The arrangement is such that at speeds below a given speed, the flange 30 is moved by the springs 42 into contact with the clutch member 23 so causing the worm 26 to be rotated in one direction. At higher speeds, the centrifugal masses 44 cause the flange 30 to be moved into contact with the fixed component 31 so causing the worm 26 to be rotated in the opposite direction. Rotation of the worm 26 causes axial movement of the screws 37 which cause the member 19 to impart angular movements to the rotor blades 10. If the axial movements of the screws 37 is such that the nuts 39 engage the flange 40, the movable flange 30 will be disengaged from the component 31 or component 23 respectively and the centrifugal mechanism rendered ineffective. In a modification, Fig. 3 (not shown), the worm wheel 26 is replaced by a spur gear which drives the nuts through a compound gear train and the screw threads on the screws 37 are replaced by re-circulating ball threads. A plurality of flyweights are also provided to balance the centrifugal forces on the rotor blades.
