The GRC follows a multi-pronged approach based on a collaborative of manufacturers, owners, researchers and consultants. The project combines analysis, field testing, dynamometer testing, condition monitoring, and the development and population of a gearbox failure database. At the core of the project are two 750kW gearboxes that have been redesigned and rebuilt so that they are representative of the multi-megawatt gearbox topology currently used in the industry. These gearboxes are heavily instrumented and are tested in the field and on the dynamometer. This report discusses the bearing calibrations of the gearboxes. 606 $aGearing$xDesign and construction 606 $aWind turbines 615 0$aGearing$xDesign and construction. 615 0$aWind turbines. 700 $aVan Dam$b J$g(Jeroen)$01387705 712 02$aNational Renewable Energy Laboratory (U.S.) 801 0$bSOE 801 1$bSOE 801 2$bSOE 801 2$bGPO 906 $aBOOK 912 $a9910703251803321 996 $aGearbox Reliability Collaborative bearing calibration$93498292 997 $aUNINA
