A kind of unmanned plane inclining rotary mechanism

Technical field

The utility model belongs to air vehicle technique field, and in particular to a kind of unmanned plane inclining rotary mechanism.

Background technology

Miscellaneous unmanned plane occurred one after another in recent years, the main Liang great branches of unmanned plane be multi-rotor unmanned aerial vehicle, Fixed-wing unmanned plane.Multi-rotor unmanned aerial vehicle can require take-off venue low, but the low endurance of speed with VTOL and hovering Short, cruise duration often only has dozens of minutes, it is difficult to meet mission requirements.Fixed-wing unmanned plane possesses faster speed and longer Endurance, but high to takeoff and anding site requirements, runway is often difficult to find.So tilting rotor wing unmanned aerial vehicle in recent years Research and development are also such as emerged rapidly in large numbersBamboo shoots after a spring rain, and various tilting rotor wing unmanned aerial vehicle is also developed in succession.However current inclining rotary mechanism but exists Some defects, common inclining rotary mechanism is servo driving link mechanism or gear set, and since unmanned machine vibration is larger, steering engine holds It is fragile, also easy to produce diastema.Verting for rotor shaft is rotated around its own axis to realize by Servo-controller drive tiliting axis, However, when insufficient torsion or gear slipping occurs in Servo-controller, often fatal, this is likely to result in tiliting axis generation The case where excessively verting, and air crash may be caused, so limiting device is must be provided on inclining rotary mechanism, to limit the angle verted Degree.

A kind of unmanned plane inclining rotary mechanism is proposed thus.

Preferably, the both sides of the tiliting axis are socketed with self-lubricating bearing by axle sleeve, and self-lubricating bearing is installed on bearing In pedestal, two bearings pedestal and No. two speed reducer housings are fixedly connected by screw with mounting plate.

Preferably, on the tiliting axis outlet hole is equipped with positioned at the both sides of No.1 speed reducer housing

The technique effect and advantage of the utility model：

1. being slowed down to stepper motor using turbine and worm combination, worm and gear can be with self-locking so that mechanism can be in office Angle of anticipating realizes self-locking.

2. slowing down using gear set, increase reduction ratio, amplifies torque.

3. being equipped with limiting device, the tilt angle of tiliting axis can be limited, prevents from excessively verting.
