Abstract
A braking device including a circular rotor coaxially fixed to the shaft of a rotary machine, a brake drum made of a material for elastic deformation and mounted on the rotor, and rollers interposed between the circular rotor and the brake drum. The rollers are adapted for rotation around the axis of the rotor as long as the brake drum maintains circularity, and adapted to be locked between the rotor and the brake drum when the brake drum is caused to deviate from circularity.
