Abstract
The invention discloses a model airplane glider propeller folding and unfolding system, and relates to the field of machinery. The system comprises a propeller clamp fixing base speed reduction drive mechanism, a power drive mechanism, a propeller clamp fixing base slide mechanism, a propeller clamp fixing base position sensing mechanism, a propeller clamp folding and unfolding mechanism and a propeller, wherein the propeller clamp fixing base speed-reduction drive mechanism is formed by connecting a speed reduction system base, a reduction gearbox motor, a small reduction gear, a large reduction gear, a reduction gearbox gear cover, a lead screw and a lead screw bearing, the power drive mechanism is formed by connecting a power motor, a transmission shaft connector and a hexagonal prism transmission shaft, the propeller clamp fixing base slide mechanism is composed of a folding and unfolding system base, a left slide guide rail and a right slide guide rail, the propeller clamp fixing base position sensing mechanism is composed of a front microswitch and a rear microswitch, and the propeller clamp folding and unfolding mechanism is formed by connecting a nut, a nut fixing base, a bearing tablet, a bearing, a propeller clamp fixing base, a propeller clamp connector and a propeller clamp. After the glider power motor is turned off, the propeller can be completely folded in the glider nose cover, wind resistance is reduced, and meanwhile the appearance vividness of a model airplane glider is improved.
Description
【Technical field】 [0001] The invention relates to the mechanical field, in particular to a propeller retractable system on a model airplane glider. 【Background technique】 [0002] In the prior art, the model airplane glider is not towed by the front machine during the lift-off process, and needs to rely on its own power to reach the gliding height. Therefore, the model airplane gliders in the prior art are all provided with power motors and auxiliary propellers, and start the auxiliary propellers during take-off to help the model airplane glider reach the gliding height or enter the updraft. Turn off the power motor to realize unpowered gliding flight. However, during unpowered gliding flight, the propellers will be folded and attached to both sides of the nose, which will increase wind resistance and generate turbulence, which will affect the gliding performance, reduce the hang time of the glider, and affect the appearance of the model glider. 【Content of invention】 ...
