Abstract

The mechanism has a central gearwheel, meshing with several pinions each driving coaxial compressor rotors. The pinion shafts are each equipped with thrust rings, which can be used to transmit the thrust loads to the thrust bearing of the gearwheel. The gear teeth can be single helical, and the driven shafts can be so spaced about the gearwheel that the resultant transverse forces cancel out. Lubricating out consumption for th drive unit is reduced by approx. 30%.
