A dual electromagnetic clutch rotor electric folding mechanism

Abstract

The utility model discloses a kind of double electromagnetic clutch rotor electric folding mechanism, its folding subassembly includes connecting piece and folding joint, respectively realize and the fixed connection of helicopter hub and blade;Its rotor folding actuator includes driving motor, reduction transfer mechanism, plug-in pin mechanism and folding unfolding mechanism, the input end of reduction transfer mechanism is connected driving motor, the output end of reduction transfer mechanism is connected to plug-in pin mechanism by first electromagnetic clutch transmission, it is connected to folding unfolding mechanism by second electromagnetic clutch transmission, can realize plug-in pin mechanism and the alternative switching of folding unfolding mechanism action.The utility model replaces the complex structure of traditional two sets of independent driving system, using single driving motor combines the design of common reduction transfer mechanism, utilizes double electromagnetic clutch alternative transmission power to plug-in pin mechanism or folding unfolding mechanism, effectively reduce the weight and space occupation of system, fit the stringent requirement of aviation mechanism for light weight and compact.
