Description
Technical field
The present invention relates to rack construction, the gearbox in small-sized single rotor unmanned helicopter frame is especially integrated in.
Background technology
Depopulated helicopter has a maneuverability, and landing is convenient, can hovering, the advantages of flying speed is controllable, extensively should
For the field such as military, agriculture and civilian.
Sheet material case structure being used current small-sized single rotor unmanned helicopter frame, it has the following disadvantages more：1、
Gearbox is separate with frame, and gearbox is connected in frame by connector, causes depopulated helicopter weight overweight, increases
The flight stress of depopulated helicopter.2nd, the frame integral rigidity of plank frame is poor, and Integral low-frequency vibrations are larger during flight, deposit
Interference is produced in potential safety hazard and to electronic equipment (gyroscope or flying control equipment).
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, and provides one kind and be integrated in small-sized single rotor unmanned helicopter
Gearbox in frame, gearbox combination in frame, is effectively reduced the weight of depopulated helicopter, when reducing flight by it
Engine meets, and simple structure, improves the integral rigidity of depopulated helicopter.
The technical scheme is that：It is integrated in the gearbox in small-sized single rotor unmanned helicopter frame, including speed change
Case lower plate and upper cover of speed changing box；
Upper cover of speed changing box is arranged on the upper end of gearbox lower plate, and gear box is combined into gearbox lower plate；
Gearbox lower plate is provided with and electrically activates motor mounting hole, engine location hole, primary axis bearing hole A, propeller shaft
Bearing hole A, tensioning wheel axis hole and tail pipe seat fixed screw holes；Upper cover of speed changing box is provided with propeller shaft bearing hole B and primary axis
Bearing hole B；
Primary axis bearing hole A, propeller shaft bearing hole A, propeller shaft bearing hole B and primary axis bearing hole B are and speed change
The inner space of box body；Primary axis bearing hole A is corresponding with primary axis bearing hole B location, propeller shaft bearing hole A and propeller
Axle bearing hole B location correspondence.
Further technical scheme is the present invention:The side of gearbox lower plate is provided with multiple locating slots.
Further technical scheme is the present invention:Electrically activate motor mounting hole, engine location hole, primary axis bearing hole
A and propeller shaft bearing hole A arrange successively side by side in gearbox lower plate.
The depopulated helicopter frame that the present invention is assembled has the following advantages that：
1st, with the cavity that can install drive disk assembly, i.e. inner chamber between upper cover of speed changing box and gearbox lower plate in frame.
Without additionally installing gearbox, the overall weight of depopulated helicopter is alleviated.
2nd, using tower structure, simple structure, assembling is easy.Set from the hole position of gearbox lower plate and can be seen that
Engine, one-level speed change, two stage speed change laid out in parallel, improve the integral rigidity of frame, reduce vibrations during flight, improve
The job stability and reliability of electronic equipment.
Below in conjunction with figure, the invention will be further described with embodiment.
