Gearbox failures are caused by various reasons, for example, absolute gear rating, bad load distribution across teeth and between planets, uncontrolled power input, rotor loads imposed on gear case etc. To reduce in these failures, it is important to define concept design robust. During the concept design, components layout which includes demanded torque, type of gearbox for torque split, calculation of power flows, gear sizing with K&C factor, bearing selections with bearing catalog and gearbox suspension systems to support the gearbox. To be optimized gear design, mechanism of flexible pin concept which can be approached by gear test of analytical method is introduced. This paper introduces concept design procedure of the wind turbine gearbox. Some kinds of design parameter are introduced and compared initial concept design with final concept design of gearbox system.
