Abstract (en)
[origin: WO2006082319A1] The invention relates to a device for braking the rotation of a drive shaft of the leaf of a high-speed door. The inventive device consists of a flange (17) which is rotated by a shaft comprising several cavities (19), each of said cavities being equipped with a wall which supports a flyweight (18) in the operating condition and which is inclined in relation to the axis of rotation of the flange by an angle of less than 90°. Moreover, each cavity comprises a proximal end which is located close to the axis of rotation of the flange and a distal end which is located at a distance from said axis of rotation. According to the invention, each flyweight (18) moves in a cavity between a position whereby the shaft operates at normal speed, in which the flyweight is disposed in a zone comprising the proximal end of the cavity (19), and a position whereby the operating speed of the shaft (4) exceeds a pre-determined threshold, in which the flyweight (18) is disposed in a zone comprising the distal end of the cavity and actuates means for braking the rotation of the shaft.
