摘要： A precessing fan system includes a fan blade connected to a precessing drive train. The precessing drive train is connected to a first support at one end and pivotably connected to a second support at another end. The precessing drive train includes a single motor having a drive shaft driving both the fan blade and orbital gearing. The orbital gearing causes precession of the drive shaft and is connected to the first support. The orbital gearing includes a gear reduction that is coupled to the drive shaft, a pinion that is coupled to the gear reduction and a ring gear coupled to the pinion. The ring gear is connected to the first support. A planetary gearing system is used for the pinion and the ring gear.
