Patent ID: 8707804

Claim:
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.
