GEAR DEVICE AND WIND ENERGY UTILIZATION DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a gear device capable of extending the lifetime of each tooth of a gear by reducing load distribution to each tooth.SOLUTION: A gear device 11 for transferring rotational power received from a power source side to a drive device driven by the rotational power, distributes the rotational power with a distribution mechanism D which distributes the rotational power received from the power source side into at least two rotational forces with a gear. Rotation shafts transferring respective distributed rotational forces are formed into a pipe shape having a different diameter, and coaxially inserted into each other.
