Abstract
The utility model provides an unmanned helicopter transmission, includes the engine pivot, driving gear, toothed belt, clutch, driven gear and screw pivot. The engine pivot is connected with the engine of unmanned helicopter. Clutch and initiative gear connection are passed through in the engine pivot. The driving gear passes through toothed belt and is connected with driven gear. Driven gear is connected with the screw pivot. Driving gear and driven gear's drive ratio is 1: 4. The utility model discloses simple structure is convenient for maintain, has reach the best drive ratio through a large amount of calculation and experiment moreover, and through the control of clutch, ability output torque when making the engine reach higher revolution can the energy saving to extension unmanned aerial vehicle's operating time.
Description
Technical field
The utility model relates to a kind of driving device, and especially a kind of depopulated helicopter driving device, belongs to unmanned air vehicle technique field.
Background technology
The structure of depopulated helicopter is fairly simple, price is also cheaper, and do not need emission coefficient, can also vertical takeoff and landing, more can freely hover, the flight alerting ability that gets up is quite superb, available various speed, flies with the air route of various flight profile, mission profile, is therefore applied in military affairs, the every field such as civilian widely.The transmission structures more complicated of existing depopulated helicopter, transmitting ratio is not quite reasonable, general employing belt-driving, if and depopulated helicopter will take off, need the revolution of screw propeller more than 400 revs/min, driving engine need slow speed of revolution gradually carrying screws rise to high rotating speed, like this with regard in vain waste a lot of energy.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides that a kind of structure is simple, transmitting ratio more reasonably depopulated helicopter driving device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of depopulated helicopter driving device, comprises engine shaft, driving gear, odontoid belt, power-transfer clutch, driven gear and screw propeller rotating shaft.Engine shaft is connected with the driving engine of depopulated helicopter.Engine shaft is connected with driving gear by power-transfer clutch.Driving gear is connected with driven gear by odontoid belt.Driven gear is connected with screw propeller rotating shaft.The transmitting ratio of driving gear and driven gear is 1:4.
Preferably, over cap is provided with in the upper end of driving gear.
The utility model structure is simple, is convenient to safeguard, and has drawn best transmitting ratio by a large amount of calculating and experiment, by the control of power-transfer clutch, just output torque when making driving engine arrive higher revolutions, can economize energy, thus extends the work-hours of unmanned plane.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of driving gear.
Fig. 3 is the structural representation of driven gear.
Detailed description of the invention
As shown in Figure 1-Figure 3: a kind of depopulated helicopter driving device, comprises engine shaft 5, driving gear 4, odontoid belt 3, power-transfer clutch 6, driven gear 1 and screw propeller rotating shaft 2.Engine shaft 5 is connected with the driving engine of depopulated helicopter.Engine shaft 5 is connected with driving gear 4 by power-transfer clutch 6.Driving gear 4 is connected with driven gear 1 by odontoid belt 3.Driven gear 1 is connected with screw propeller rotating shaft 2.The transmitting ratio of driving gear 4 and driven gear 1 is 1:4.Over cap 7 is arranged on the upper end of driving gear 4.
When car bonnet revolution reaches more than 300 revs/min time, power-transfer clutch adhesive, driving gear is engaged with engine shaft, and output torque is to screw propeller.
