Abstract

The invention discloses an aerial propelling device suitable for an amphibious unmanned aerial vehicle. A first blade and a second blade of the propelling device are mounted at two ends of a second flange. A third blade and a fourth blade are mounted at two ends of a first flange. A first bevel gear, a third bevel gear and a fourth bevel gear are connected to a cross shaft through bearings. The second bevel gear is mounted on the first flange. The fourth bevel gear is mounted on the second flange. A blade motor drives a middle shaft to transmit motion to the first flange, the rotation of the first flange drives the first bevel gear to move so as to allow the other three bevel gears to move, and then four blades are moved. The front blade layer and the rear blade layer of the propelling device rotates coaxially, the rotation directions of the front blade layer and the rear blade layer are opposite, and accordingly influence, caused by deflection torque of one-way rotation, on flying attitude of the unmanned aerial vehicle can be balanced, and aerial flight control of the unmanned aerial vehicle is facilitated.

Description

technical field [0001] The present invention relates to an unmanned aerial vehicle, more particularly, refers to an aerial propulsion device for an unmanned aerial vehicle suitable for water-air amphibious survivability. Background technique [0002] UAV is the abbreviation of unmanned aerial vehicle, and the English abbreviation is UAV (Unmanned Aerial Vehicle). [0003] The most important requirement for the design of the UAV is to be as light as possible while the fuselage system is strong enough. However, UAVs under various mission load requirements leave very limited space and quality quotas for motion transmission mechanisms. It is necessary to flexibly and efficiently convert basic engineering driving motions, such as high-speed rotation, into favorable controlled motions. The basic aviation transmission methods include direct drive, proportional amplification drive, electric servo drive and hydraulic servo drive. [0004] UAV is an unmanned aircraft operated by rad...
