Abstract: A rotor shaft system for a vehicle includes a rotor shaft having a first shaft end opposite a second shaft end. The rotor shaft has a first segment and a second segment defined between the first shaft end and the second shaft end. The rotor shaft system includes a shaft gear coupled to the rotor shaft between the first shaft end and the first segment, and a shaft sleeve coupled to the first segment so as to surround a portion of the shaft gear. The rotor shaft system includes a lubrication system defined at least partially through the rotor shaft and the shaft sleeve. The lubrication system is to supply a fluid to at least a portion of the rotor shaft and the shaft sleeve.
