Multi-shaft turbomachine drive with sun wheel and hollow pinions

摘要

Turbo-stages are driving, or driven, via the hollow pinion (4) outer toothing and via epicyclic drives in the hollow pinions. The turbo-stages are located on the same output shaft with the sun wheels of the epicyclic drivers with stationary planetary gears. One or more intermediate gears (3) are incorporated between the centre sun wheel (2) and the outer toothings of the hollow pinions. Pref. the sun wheel, the intermediate gears, and the hollow pinion outer toothings have an identical module. The intermediate gear may mesh with two coaxial, separate outer toothings.
