Main rotor shaft of single rotor unmanned aerial vehicle and processing technology thereof

Abstract

The invention relates to a main rotor shaft of a single rotor unmanned aerial vehicle. The main rotor shaft comprises a main shaft and an auxiliary shaft, wherein the main shaft and the auxiliary shaft are cylindrical; the main shaft comprises a shaft head, a shaft body and a shaft tail; the diameter of the shaft tail is smaller than that of the shaft body; the shaft head and the shaft tail are spline shafts; an inner hole formed along the direction of a central shaft is formed in the main shaft; the auxiliary shaft comprises a body and a connecting part and a fixing part arranged at two endsof the body; the body of the auxiliary shaft is connected to the inner hole in transition fit; the concentricity of the main shaft and the auxiliary shaft is 0.01mm; the fixing part is connected to the inner hole in the shaft tail in transition fit; nitriding layers are arranged on the surfaces of the shaft head and the shaft tail; and chromium coatings are arranged on the surface of the shaft body, the surface of the inner hole and the surface of the auxiliary shaft. The invention provides the main rotor shaft of the single rotor unmanned aerial vehicle simple in structure, high in precisionand impact resistant. Moreover, the main rotor shaft is excellent in processing technology and high in precision and meets the high standard demand.

Description

technical field [0001] The invention relates to the technical field of UAV processing, in particular to a main rotor shaft of a single-rotor UAV and a processing technology thereof. Background technique [0002] The main rotor shaft of the existing UAV is usually processed by a lathe in one piece, and then the corresponding precision requirements are met through finishing machining, and then heat treatment and chrome plating are performed to improve the performance of the main rotor shaft. The performance of the rotor shaft meets the corresponding requirements, but for the main rotor shaft with high standard requirements, when processing the inside of the main rotor shaft with a large diameter, it cannot meet the high standard requirements, and the processing is not complete. , so there are limitations in impact resistance, wear resistance and service life, which will cause safety hazards during use. Contents of the invention [0003] The purpose of the present invention ...
