2results about How to "Optimize the power transmission path" patented technology

This application relates to the field of unmanned aerial vehicle (UAV) technology, and particularly discloses a propeller clamping device and a UAV. The propeller clamping device includes a propeller blade, a propeller clamping seat, a vibration damping mechanism, and a base assembly. The propeller clamping seat has a first clamping portion and a second clamping portion, symmetrically arranged on both sides of the propeller clamping seat along a first direction. The first clamping portion clamps one propeller blade, and the second clamping portion clamps another propeller blade. The vibration damping mechanism includes a first shim and a second shim. Along a second direction, two first shims are respectively disposed on both sides of the propeller blade and located between the propeller blade and the first clamping portion, and two second shims are respectively disposed on both sides of another propeller blade and located between the propeller blade and the second clamping portion. The propeller clamping seat is mounted on the base assembly. Through the above structure, the first shims and the second shims can improve the force transmission path between the propeller blade and the first and second clamping portions, absorb the vibration and impact force in the rotational axis when the propeller blade rotates, reduce friction and wear between the propeller blade and the propeller clamping seat, and extend service life.
