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.
Claims19
A torque or force calibration device for a unit intended to measure or to apply a torque or a force respectively, said device comprising:
- a first part, a second part, and at least one flexible element linking the first part to the second part, the second part being mounted to be mobile in rotation or in translation relative to the fixed first part, the device comprising an abutment that limits the displacement of the second part and thereby sets the maximum torque or the maximum force of the calibration device,
- wherein the first part and the second part are each formed by a planar base topped by an upright onto which is fixed an end of the flexible element, the first part and the second part being disposed head to tail with the base of the first part forming the support of the device and the base of the second part forming the portion to which the torque or the force is applied during the calibration of the unit.
A torque or force calibration device for a unit intended to measure or to apply a torque or a force respectively, said device comprising:
- a first part, a second part, and at least one flexible element linking the first part to the second part, the second part being mounted to be mobile in rotation or in translation relative to the fixed first part, the device comprising an abutment that limits the displacement of the second part and thereby sets the maximum torque or the maximum force of the calibration device,
- wherein the flexible element is formed by a blade or a sectional bar.
A torque or force calibration device for a unit intended to measure or to apply a torque or a force respectively, said device comprising:
- a first part, a second part, and at least one flexible element linking the first part to the second part, the second part being mounted to be mobile in rotation or in translation relative to the fixed first part, the device comprising an abutment that limits the displacement of the second part and thereby sets the maximum torque or the maximum force of the calibration device,
- wherein an envelope of the device forms a straight prism with square or rectangular base having no dimension exceeding 5 cm.
