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.
Claims20
A dynamic load bench adapted for applying radial loads and variable torques on a rotary shaft of a mechanism to be tested, said dynamic load bench comprising two identical reproduction modules arranged generally parallel and generally symmetrical 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 and rotatable in a first direction;
- a torsional rod coaxially positioned with said driving shaft of the torque motor, said torsional rod comprising two ends;
- and
- a connecting rod and a crank connecting one of the ends of the torsional rod to said shaft to be tested, said connecting rod defining a plane generally perpendicular to an axis defined by said shaft to be tested and to said driving shaft of said torque motor so that, in said plane, said connecting rods of the two modules are parallel and symmetrically offset from each other relative to the shaft to be tested.
A dynamic load bench adapted for applying radial loads and variable torques on a rotary shaft of a mechanism to be tested, said dynamic load bench comprising a first reproduction module and a second reproduction module, each with a housing being spaced from the other, and wherein each module comprises:
- a torque motor with a driving shaft positioned to be parallel to said shaft to be tested, said torque motor of rotatable in a first direction;
- a torsional rod coaxially positioned with said driving shaft of the torque motor;
- and
- a crank having an input end rotatably coupled to said torsional rod for rotating by said torsional shaft and an output end coupled to a connecting rod;
- said connecting rod movable by said crank along a generally vertical plane, which is generally perpendicular to an axis defined by a rotary shaft to be tested and an axis of the driving shaft;
- wherein the output end of the crank connected to the first reproduction module is positioned at 180° offset relative to the output end of the crank connected to the second reproduction module.
