Abstract
The present disclosure relates to a load bench for applying on the rotary shaft of a device to be tested, such as an actuator or the like, radial loads and variable torques provided by controlled reproduction means. Advantageously, the controlled reproduction means include two identical reproduction modules arranged in parallel and symmetrically relative to the rotary shaft to be tested, each of which comprises a torque motor, a torsion rod, and a connecting rod-crank connection connecting the torsion rod to the rotary shaft of the mechanism to be tested.
Claims10
A dynamic load bench adapted for applying, on the rotary shaft of a mechanism to be tested, such as an actuator or the like, radial loads and variable torques provided by controlled reproduction means, said controlled reproduction means of said radial loads and said variable torques including two identical reproduction modules, arranged parallelly and symmetrically relative to said rotary shaft to be tested, wherein each module comprises:
- a torque motor with a driving shaft parallel to said shaft to be tested, said torque motors of said two modules rotating in the same direction;
- a coaxially integral torsional rod, through one of its ends, with said driving shaft of the torque motor;
- and
- a connecting rod-crank connection connecting the other end of said torsional rod to said shaft to be tested in a plane perpendicular to the latter and to said driving shafts, so that, in said perpendicular plane, said connecting rods of the two modules are parallel and symmetrically offset by 180° from each other relative to the shaft to be tested and to their respective driving shafts by said cranks.
