## Abstract

A transmission turbo machine integrates drive units and/or driven units into a machine train via a transmission. The integrated transmission substantially comprises a central large wheel with a shaft and a plurality of pinions with pinion shafts. The large wheel is operatively connected to the pinions, and the ends of the pinion shafts are operatively connected to a drive unit and/or driven unit. The shaft of the large wheel is operatively connected to a drive unit and/or driven unit. The invention is characterized in that the drive unit and/or driven unit is an axial expander which is mounted in a cantilevering manner in one or more stages.
