<p>The device (10) has a connection unit (60) i.e. tube, for connecting a support (20) with a hub (2) of a rotorcraft. A drive shaft (70) and a drive unit (80) i.e. electric motor, rotate with first speed of rotation that is greater than second speed of rotation of the hub. The drive shaft rotates about an axis of rotation (AX1) of the support. The connection unit is connected to the support by a connection part (90) provided with a ball bearing (91), to enable the support to rotate about the axis of rotation relative to the connection unit. An independent claim is also included for a rotorcraft comprising a main rotor.</p> |
