Power-split transmission for use in wind power plant, has drive tooth formed at drive-sided shaft, and planetary gearings engaged with output tooth over respective coupling shafts, where coupling shafts run coaxial to drive-sided shaft

摘要

The transmission (10) has a rotatably supported drive-sided shaft (11), and a drive tooth (12) formed at the shaft. An output tooth (14) is formed at an output-sided shaft (13). First and second planetary gearings (17, 18) are formed at a set of planetary shafts (15). Third and fourth planetary gearings (21, 22) are formed at another set of planetary shafts (16). The first and third planetary gearings are engaged with the drive tooth. The second and fourth planetary gearings are engaged with the output tooth over respective coupling shafts (26, 27) that run coaxial to the drive-sided shaft.
