Meet, it is and simple in construction, improve the integral rigidity of depopulated helicopter.
The technical solution of the utility model is：The rack construction of small-sized single rotor unmanned helicopter, including base plate, support are erected
Plate, gearbox lower plate and upper cover of speed changing box；
Base plate is located at the lower section of gearbox lower plate, and support riser lower end is connected with base plate, and upper end is connected with gearbox lower plate；
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；
Base plate is provided with water pump mounting hole, battery mounting hole and engine fixed screw holes；Gearbox lower plate is provided with
Electrically activate motor mounting hole, engine positioning 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 chamber connection 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.
The further technical scheme of the utility model is:Base plate includes plate A and plate B, and plate A and plate B are used by supporting riser
Bolt connection is integrated；Water pump mounting hole, battery mounting hole and engine fixed screw holes are respectively positioned on plate A.
Further technical scheme is the utility model:Electrically activate motor mounting hole, engine positioning hole, primary axis axle
Bearing bore A and propeller shaft bearing hole A arrange successively side by side in gearbox lower plate.
The utility model has the following advantages that compared with prior art：
1st, the inner chamber between the cavity of drive disk assembly, i.e. upper cover of speed changing box and gearbox lower plate can be installed by being carried in frame.
Without additionally installing gearbox, the overall weight of depopulated helicopter is alleviated.
2nd, simple in construction using tower structure, assembling is easy.Set and can be seen that from the hole position of gearbox lower plate
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.
The utility model is further described below in conjunction with figure and embodiment.
