Usage Example
Wind power generator
Features
This drawing is the planetary gear unit for a wind power generator. Planetary gear units available both for speed up and reduction gears. Input high torque with low speed fan rotation to planetary gear units, and output low torque with high speed revolution power. By revolution coaxial two input shafts in the opposite direction, it is possible to originate higher speeds up ratio.
Rotating ratio of each shaft
NS=i×NC-(i-1)×NI
i=Reduction ratio
[Example]
When i=4.3 NC=1rpm NI=-1
NS=4.3×1-(4.3-1)×(-1)=7.6
