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.

Abstract: A torque or force calibration device is for a unit intended to measure or to apply a torque or a force respectively. The device includes a first part, a second part, and at least one flexible element linking the first part to the second part. The second part is mounted to be mobile in rotation or in translation relative to the fixed first part. The device includes an abutment which limits the displacement of the second part and thereby sets the maximum torque or the maximum force of the calibration device.
