Abstract

The invention relates to a brake device of an unmanned aerial vehicle rotor wing. The brake device comprises a drive shaft, a concentric drive gear, a brake disc A, a driven shaft, a concentric driven gear and a brake disc B. The concentric drive gear is fixedly connected to the output end of the drive shaft, the brake disc A is arranged on the drive shaft, the concentric driven gear is fixedly connected to the input end of the driven shaft, and the brake disc B is arranged on the driven shaft. The rotor wing comprises a rotor wing head and a main shaft, and a concentric main shaft gear is arranged on the main shaft. A brake component A is arranged on the brake disc A of the brake device, and a brake component B is arranged on the brake disc B. The drive gear and the driven gear are symmetrically arranged in a concentric mode, the main shaft gear is respectively meshed with the drive gear and the driven gear, and the main shaft gear, the drive gear and the driven gear are spiral beveled gears. In the prior art, when the main shaft gear brakes for deceleration, abrasion, caused by relative torsion and stress concentration, to the main shaft gear is reduced, and stability is improved when the rotor wing decelerates for transmission.

Description

technical field [0001] The invention belongs to the technical field of braking devices, and in particular relates to a braking device applied to the rotor of an unmanned aerial vehicle. Background technique [0002] With the development of UAV technology, especially the rapid development of unmanned helicopters, its application is becoming wider and wider, and it is indispensable in both civilian and military fields. However, when the unmanned helicopter is operating in the air, the engine drives the rotor to rotate extremely fast, the sweeping area of ​​the rotor is relatively large, and the inertia of the fuselage and the rotor is relatively large during motion. When the rotor is out of control, if it cannot be braked in time, its powerful destructive force may cause great harm to the ground crowd or buildings. [0003] Chinese patent CN203009640U discloses a braking device for an unmanned rotor helicopter in the air. Its structure is: a cavity is provided inside the conc...
