Unmanned plane tail rotor

Abstract

The invention discloses an unmanned plane tail rotor, which comprises a rotating tail shaft, a paddle clamping shaft, a damping material, paddle clamps, tail rotor head deep groove ball bearings, thrust bearings and a fixing element, wherein one end of the rotating tail shaft is vertically arranged on a tail paddle fixing seat of an unmanned plane; a tail rotor head is fixed and installed on the other end of the rotating tail shaft through the fixing element; the paddle clamping shaft is arranged on the tail rotor head and is vertical to the axial direction of the rotating tail shaft; the damping material is arranged on the tail rotor head, and is installed and fixed in a way of being matched with the outer wall of the paddle clamping shaft; two ends of the paddle clamping shaft are respectively connected with the paddle clamps; the deep groove ball bearing is arranged on each paddle clamp; in addition, the thrust bearings and the paddle clamps are installed on the paddle clamping shaft through fastening screws. The unmanned plane tail rotor has the advantages that the structure is simple; the assembly is convenient; the flight of the unmanned plane can be stable; in addition, the service life of the unmanned plane can be effectively prolonged.

Description

technical field [0001] The present invention relates to UAV parts, in particular, to UAV tail rotor. Background technique [0002] At present, the commonly used UAV tail rotor usually installs the paddle clamp shaft on the rotating tail shaft through a fixed pin. During the forward flight of the man-machine, the tail of the UAV vibrates a lot, which will affect the movement of the tail rotor, and the rigid connection between the paddle clamp shaft and the head and tail of the tail rotor will not reduce the vibration, which will cause the UAV to fly incorrectly. Stable, and the wear speed of the parts on the UAV is accelerated, and it is prone to breakage between the rotating shaft and the connecting shaft of the blades. It is difficult for the UAV to meet the requirements of precise control of flight. [0003] Therefore, there is an urgent need to provide a UAV tail rotor with reasonable design, simple assembly, stable flight of the UAV, and effective prolongation of the se...
