Rotor wing supporting device of model helicopter

Abstract

The invention provides a rotor wing supporting device of a model helicopter, comprising a rotor wing wheel hub chassis, a bearing cross beam, a motor, a speed reducer and four V-shaped brackets; wherein four bulges are distributed on the outer circle of the rotor wing wheel hub chassis, with a wheel hub central axis as a center, and four round holes are arranged on the upper edges of the bulges and vertical to the tangential directions of a wheel hub axis; each C-shaped bracket is composed of two struts which are connected into a whole at the bottoms, and each V-shaped bracket is provided with two mounting holes at the top and one mounting hole at the bottom, the central axes of the two mounting holes on the top form a 90-degree angle, and the two mounting holes on the top and the connecting rod of each V-shaped bracket form a certain angle; the top of each V-shape bracket is arranged on the two adjacent mounting holes of the rotor wing wheel hub chassis; the mounting hole at the bottom of each V-shaped bracket is arranged on the bearing cross beam of the model helicopter; and the drive motor and the speed reducer are fixed on the rotor wing wheel hub chassis. In the invention, the oscillation generated by the helicopter is absorbed by the V-shaped brackets, which can reduce the trembling of the helicopter body, enhance the maneuverability and simultaneously reduce the damage to a drive shaft transmission shaft.

Description

technical field [0001] The invention relates to a component of a model airplane helicopter, in particular to a supporting device for a rotor system of a model airplane helicopter. Background technique [0002] At present, the rotor damping system of model airplane helicopters is mostly installed inside the rotor system, for example, the damping mechanism ZL: 01103884.5 is installed on the main blade. However, the entire rotor system will also cause greater vibration to the fuselage. Because the rotors of most model aircraft helicopters are directly fixed on the body, if the vibration generated by the rotation of the rotor can be absorbed again through the support device of the entire rotor system, the vibration problem of the model aircraft helicopter will be better solved. [0003] There are generally two ways to fix the rotor system of the model helicopter, one is to fix it on the roof of the model helicopter, and the other is to fix it directly on the load-bearing beam a...

AI Technical Summary

Problems solved by technology

Using the rotor system support method of the above scheme, the rotor will generate a lot of force when the aircraft model helicopter performs some stunts, such as dives, sharp turns, or even rollovers, and the fuselage and the main shaft of the transmission system directly bear these forces , it will cause great damage to the transmission system, and at the same time, it will cause great tremors to the body, and even cause the aircraft model helicopter to fall apart.
