Abstract:
1. A gearbox test rig for testing first and/or second gearboxes having power ratings of 1 MW or more, the gearbox test rig comprising: a first coupler for coupling a low-speed shaft of a first gearbox to a low-speed shaft of a second gearbox such that forces can be transmitted between the low-speed shafts of the first and second gearboxes; and a second coupler for coupling a high-speed shaft of the first gearbox to a high-speed shaft of the second gearbox such that forces can be transmitted between the high-speed shafts of the first and second gearboxes, wherein the second coupler comprises a hydraulic rotary actuator for regulating a torque which is applied to the high-speed shafts of the first and second gearboxes.
