Abstract：The planetary bearing is one of the most important components for wind turbine gearboxes,due to the complication of the load and the special position.How to analyze the load center becomes the critical job for design engineers.Based on current design specifications,two 3 MW gearboxes with back to back arrange-ment are tested on the 10 MW testing benches,and strain testing is conducted on planetary gears during the ex-periment.For further utilization of these testing results about the strain of the gear,the least square method is taken to precisely estimate the load position of the applied center for the planetary bearings during the develop-ment for the new wind turbine gearbox.
