Abstract
The utility model discloses an aerial secondary starting drive of unmanned aerial vehicle engine, including first gear, second gear, third gear, fourth gear, motor, one -way bearing, engine main shaft, first gear is installed on the engine main shaft through one -way bearing, first gear and the 2nd gear engagement, the second gear is all installed in the pivot with the third gear, install the fourth gear on the motor, fourth gear and the 3rd gear engagement, the motor links to each other with protection device. The utility model discloses use miniature big torsion DC Brushless motor as power resources, through two -stage 9.7: 1 reducing gear drive the main shaft of engine. And installing the biggest one -level gear on the engine main shaft through one -way bearing, after the engine was started, the rotational speed was higher than the rotational speed that the motor produced, in gear wheel separation, motor stop work thereupon under the effect of one -way bearing.
Description
[technical field]
The utility model relates to the technical field of small unmanned vehicle, particularly the technical field of restarting device.
[background technology]
At present for unmanned plane and the small unmanned vehicle of agricultural production, due in order to promote, universal, so structure is simple, cost relative moderate.While reduction cost, there are this some labile factors in the major part driving engine of unmanned plane, owing to have employed the driving engine of double stroke Manufacturing Technology for Carburetors, makes driving engine under working long hours, there will be job insecurity, the phenomenons such as idling flameout.If run into misfiring condition awing, just need restarting driving engine aloft.Because driving engine exists higher compression ratio, so need the actuating device providing quite large torsion.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes the aerial restarting device of a kind of unmanned vehicle engine, and restarting when can make engine off, improves larger torsion.
For achieving the above object; the utility model proposes the aerial restarting device of a kind of unmanned vehicle engine; comprise the first gear, the second gear, the 3rd gear, the 4th gear, motor, unilateral bearing, engine spindle; described first gear is arranged on engine spindle by unilateral bearing; first gear and the second gears meshing; described second gear and the 3rd gear are installed in rotating shaft; described motor is provided with the 4th gear; 4th gear and the 3rd gears meshing, described motor is connected with fender guard.
As preferably, described motor is miniature large torsion DC brushless motor.
As preferably, the ratio of number of teeth of described first gear and the second gear is 9.7:1, and the ratio of number of teeth of described 3rd gear and the 4th gear is 9.7:1.
As preferably, described unilateral bearing is locked on the first pinion rotation direction.
The beneficial effects of the utility model: the utility model provides larger torsion source by the mode be combined with the 4th gear by miniature large torsion DC brushless motor; First gear and the second gears meshing, the 4th gear and the 3rd gears meshing, the second gear and the 3rd gear are installed in rotating shaft and realize large torsion ratio, finally provide larger torsion; Unilateral bearing is locked on pinion rotation direction ensure that the first gear can drive engine spindle to rotate when driving engine does not start, and engine start rear engine can be separated with the first gear; Driving engine is separated rear self-con-tained unit and sends stoppage in transit signal with big gear wheel, motor is out of service.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the front view of the aerial restarting device of a kind of unmanned vehicle engine of the utility model;
Fig. 2 is the birds-eye view of the aerial restarting device of a kind of unmanned vehicle engine of the utility model.
In figure: 1-first gear, 2-second gear, 3-the 3rd gear, 4-the 4th gear, 5-engine spindle, 6-motor, 15-unilateral bearing, 23-rotating shaft, 61-self-con-tained unit.
[detailed description of the invention]
Consult Fig. 1 and Fig. 2, the aerial restarting device of a kind of unmanned vehicle engine of the utility model, comprise the first gear 1, second gear 2, the 3rd gear 3, the 4th gear 4, motor 6, unilateral bearing 15, engine spindle 5, described first gear 1 is arranged on engine spindle 5 by unilateral bearing 15, first gear 1 engages with the second gear 2, described second gear 2 and the 3rd gear 3 are installed in rotating shaft 23, described motor 6 is provided with the 4th gear 4,4th gear 4 engages with the 3rd gear 3, and described motor 6 is connected with self-con-tained unit 61; Described motor 6 is miniature large torsion DC brushless motor; The ratio of number of teeth of described first gear 1 and the second gear 2 is 9.7:1, and the ratio of number of teeth of described 3rd gear 3 and the 4th gear 4 is 9.7:1; Described unilateral bearing 15 is locked in the first gear 1 rotation direction.
Utility model works process:
In a kind of unmanned vehicle engine of the utility model aerial restarting device busy process, when engine off, self-con-tained unit 61 sends actuation signal, motor 6 starts, by the engagement of the 4th gear 4 and the 3rd gear 3, the coaxial rotation of the 3rd gear 3 and the second gear 2, the engagement of the second gear 2 and the first gear 1, large torsion is provided, drive engine spindle 5 to rotate by unilateral bearing 15, engine start the most at last, engine start rear engine is separated with the first gear 1, at this moment self-con-tained unit 61 sends stoppage in transit signal, and motor 6 is out of service.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
