Design and Application of a Planetary Gearbox for Small Wind Turbines

摘要

A planetary gear train consists of a sun gear,planet gears,and a ring gear and these gears are arranged as a concentric circle type.The gearbox proposed in this study arranges the planetary gear type as a double planetary gear train in which the output of the primary gear train is used as an input to the secondary planetary gear for accelerating its speed.In this design,a method that directly connects the input and output sections is introduced to obtain a high acceleration ratio and its applicability is verified for applying it to a small wind turbine through designing and fabricating the planetary gearbox.
