Gear Lubrication: Long-Term Protection for Wind Turbines
behavior of gear oils on gears were performed on a FZG back-to-back gear test rig (Ref. 7; Fig. 6). The FZG back-to-back gear test rig utilizes a recirculating power loop principle — also known as a four-square configu-ration— in order to provide a fixed torque (load) to a pair of test gears. The test gearbox and drive gearbox are connected
