A cogwheel drive mechanism for driving at least one aircraft propeller or helicopter rotor through two transmissions, with two axially displaced transmission-connection shafts and at least one output shaft in the form of a propeller shaft or rotor shaft. The object is to ensure that at least one driven section will remain fully functional between one of the transmissions and one propeller or the other during any conceivable type of malfunction. There are two spatially separated individual drive mechanisms, each of which is accommodated in a separated housing that accommodates sections of one or both of the output shafts and each of which has one of the two connecting shafts.
