Rotorcraft rotor with constant velocity joint and a torque-splitting differential

摘要

The rotor engagement system has a rotor shaft (7) and shaft connections. There are two blade retainers. There is a differential mechanism separating static coupling and authorizing relative movement perpendicular to the shaft axis between two units (40,41) of the drive unit. the differential mechanism is made up of three discs (9,10,11) superimposed and coaxial around the shaft axis.
