Planetary gear with sun wheel on central shaft

摘要

The planetary gear with sun-wheel (2), at least one hollow wheel (12) and pinion cage comprise a group of stepped planets with large and small step wheels (4,6;4A,6A). The large step wheels (4,4A) engage with the sun wheel which is radially cantilevered in the meshing with the large step wheels. The number of teeth of the large step wheels cannot be divided into whole numbers by the number of teeth of the small step wheels.
