<p>The device for calibrating torquemeters (100) fitted with a hollow twistable shaft (101) and with a torsion sensor (102), comprises a drive shaft (20) which penetrates inside the hollow twistable shaft (101) and is driven by a low-power motor. The drive shaft (20) is fitted with a hydraulic actuator (30) supplied with hydraulic fluid at a controlled static pressure (Ps). The actuator (30) consists of a first part (31) comprising at least one cylinder (53) linked in rotation with a first end (111) of the twistable shaft (101) and with a second part (32) fitted with at least one piston (54) linked in rotation with a second end (112) of the twistable shaft (101). <IMAGE></p> |
