Abstract
A motor gearbox assembly for an aircraft may comprise a layshaft configured to transmit torque from a rotor to a main power output shaft. The motor gearbox assembly may comprise a gearbox housing, a stator mounted inside the gearbox housing, a rotor rotatably mounted inside the stator on a main power output shaft and a layshaft rotatably mounted in the gearbox housing outside of the stator. The motor gearbox assembly may comprise a first ear reduction between the rotor and the layshaft, and a second gear reduction between the layshaft and the main power output shaft.
Claims15
A motor gearbox assembly, comprising:
- a gearbox housing;
- a motor inside the gearbox housing, the motor comprising a stator and a rotor that is rotatable with respect to the stator;
- a main power output shaft, the rotor being rotatably mounted on the main power output shaft and coupled to a first rotor pinion gear;
- a layshaft rotatably mounted in the gearbox housing outside of the motor;
- a first layshaft gear at a first axial end of the layshaft on a first side of the rotor and the stator, the first layshaft gear being engaged with the first rotor pinion gear;
- and
- a second layshaft gear at a second axial end of the layshaft, the second axial end being on a second side of the rotor and the stator that is opposite the first side, the second layshaft gear being engaged with a power output gear coupled to the main power output shaft.
