Self-balancing propeller assembly

A device for self-balancing a rotating part along a given longitudinal axis in plane of rotation of the rotating part, wherein the device is adapted to allow the rotating part freedom to move along the longitudinal axis, and further comprises linkages to move at least one-pair of balancing weights when the rotating part undergoes movement along the longitudinal axis under a force acting generally along the longitudinal axis being caused by an unbalanced mass on the rotating part;

• wherein the device further incorporates at least a single pair of levers comprising a first lever and a second lever, and the first lever and the second lever are arranged transverse to the longitudinal direction of the rotating part on diametrically opposite sides;
• wherein the movement of the pair of balancing weights results in providing a balancing force that neutralizes force caused by the unbalanced mass on the rotating part;
• wherein the freedom to the rotating part for linear movement along the longitudinal axis is provided by a mounting plate that operatively couples the rotating part to a drive shaft for rotation along with the shaft;
• and
• wherein the mounting plate incorporates a square shaft that engages with a slot in a support disc that is fixed to the rotating part to impart rotational movement of the mounting plate to the rotating part.
