Abstract

Device for maintaining constant the angular velocity of a rotary element, axis of rotation is mounted in a frame subjected to angular accelerations, a device characterized in that it comprises a stabilizing rotating element (4) kinematically linked to the rotating element that has been stabilize (1), that is, the element whose angular velocity must be kept constant and which rotates in the opposite direction; being the ratio between the moments of inertia (I2, I1) with respect to the axes of the stabilizing element (4) and the element to be stabilized (1) equal to the reciprocal of the transmission ratio (T) between the element to be stabilized (1), considered a driver, and the stabilizing element (4), considered driven.
