Power-split transmission for use in wind power plant, has central wheel staying in tooth engagement with planetary teeth of uniformly shaped planetary shafts such that central wheel provides output of transmission

摘要

The transmission (1) has multiple uniformly shaped planetary shafts (30) rotatably radially outwardly arranged around other uniformly shaped planetary shafts (20). The former shafts include planetary teeth, where two teeth of the planetary teeth stay in tooth engagement with planetary teeth of the latter shafts. A central wheel (40) is rotatably mounted radially inward of the former shafts coaxial to a drive shaft (10). The central wheel stay in tooth engagement with other planetary teeth of the former shafts such that the central wheel provides an output of the transmission.
