This shows a drawing of planetary speed-up gear unit for a wind power generator.
Planetary gear units are available both for speed up and reduction gears. Inputs high torque with low speed fan rotation to a planetary gear unit, and output low torque with high speed revolution power. By revolving coaxial two input shafts in the opposite direction, it is possible to originate higher speed-up ratio.
