Abstract
A device for measuring horological shakes, including a structure carrying an articulated mechanism with a compliant mechanism having a linear force/stroke characteristic connecting a first fixed element to a second element capable of moving linearly under the effect of an actuator manoeuvring same in a contactless manner in both directions, and a position sensor determining the position of the second element in a direction, and a load sensor determining the variation in the axial pushing or pulling load of the second element carrying a gripper clamping a mobile component, and/or the variation in the gradient of this load, generating a signal for triggering the position measurement during each sudden change in gradient of the load in each direction of running, to determine the shake of the mobile component, by comparing the positions measured during the sudden changes in gradient during the outward and return strokes.
