The invention belongs to the technical field of unmanned aerial vehicles and discloses a multi-rotor gear reversing mechanism and an unmanned aerial vehicle. The multi-rotor gear reversing mechanism comprises: an intermediate reverser including a first box, a large bevel gear rotationally disposed in the first box and at least three small bevel gears engaged with the large bevel gear, wherein thesmall bevel gears are not engaged with one another, and at least one small bevel gear is a power input source; rotor reversers in one-to-one correspondence with the small bevel gears, wherein each rotor reverser includes a second box, a rotor bevel gear rotationally disposed in the second box, an input bevel gear engaged with the rotor bevel gear, and the input bevel gear is driven to rotate by the corresponding small bevel gear. With the intermediate reverser and the rotor reverser for two-stage reversing, the multi-rotor gear reversing mechanism has the advantages that the traditional reversing structure is simplified, the structural weight is reduced, and transmission efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor gear reversing mechanism and an unmanned aerial vehicle. Background technique [0002] With the development of UAV technology, it has played an indispensable role in aerial photography, detection, stability maintenance, investigation, rescue, plant protection, etc., and has occupied an extremely important position in both civilian and military fields. In recent years, multi-rotor UAVs have gradually become the mainstream in the field of UAVs, and multi-rotor UAVs of various styles and functions have appeared in the market. [0003] Most of the existing multi-rotor UAVs are powered by electric motors, but the energy density of batteries is far lower than that of fuel, so most of the existing multi-rotor UAVs have the disadvantages of small load capacity and short battery life. Seriously restrict the development of multi-rotor UAV. The oil-powered m...
