Gearbox architecture – the type of gearing used, the overall gear ratio, the number of increaser stages, the number of meshes, the ratio combinations, and the gear proportions-- can have a profound effect on the "package" size of a wind turbine. In this paper the author applies a common set of requirements to a variety of potential gearbox designs for a 2.0 mW wind turbine and compares the resulting "geared component" weights, gearbox envelope sizes, generator sizes, and generator weights. Each design option is also evaluated for manufacturing difficulty via a relative cost estimate.
