Toothed wheel gear unit for a compressor system

摘要

A toothed wheel gear unit for a compressor system includes a central wheel gear (5) which drives output shafts (9) connected with one or more compressors by way of pinions (7) on the output shafts (9). On at least one of the output shafts (9a) the pinion forms the sun gear of a planetary gear (15). The planet carrier (23) of the planetary gear (15) is held stationary, and the ring gear (17) of the planetary gear (15) has outer teeth (27) in engagement with the central wheel (5) and inner teeth meshing with the planet gears (21) rotatably supported on the planet-carrier (23).
