ECCENTRIC TOOTHED ROTOR SET HAVING PLANETARY GEARS ON THE INNER ROTOR

摘要

The invention relates to a toothed rotor set for a pump or a motor. Said set consists of a rotatable outer rotor which is provided with an approximately star-shaped bore having a fine inner toothing and an inner rotor that is accommodated in the bore in an excentrical manner. Said inner rotor is provided with bearing pockets for planetary gears that are provided with a fine toothing by means of which said gears unwind in the fine toothing of th e outer rotor. The planetary gears produce a toothing which forms an outer toothing that is provided with one tooth less than the inner toothing of the outer rotor.
