- 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
