Abstract
The invention discloses an aircraft door opening or locking drive mechanism. A drive form of the combination of a worm, a gear and a planetary gear train is adopted; speed reduction is realized by adopting worm gear and worm drive; a drive ratio is adjusted by gear drive; suitable parameters are selected; the planetary gear train is adopted for drive; and the requirement on large torque is met. The mechanism has the advantages that: the number of drive series is less; the number of parts is reduced; and the weight of the used parts is relatively low, which is a primary consideration factor for aircraft performance.
Description
Technical field
Be used for aviation field, be applicable to the occasion of big retarding ratio and force-increasing mechanism, particularly a kind of aircraft door is opened or the locking driving mechanism.
Background technology
What the unlatching that present aircraft door is used and the drive part of retaining mechanism adopted is the driving type of spur gear and planetary gear combination, this type of drive gearratio is less, the gearratio of every grade of gear combination is generally 3-5, if occasion at big speed ratio, used gear number is more, the corresponding increase of connector and support member, weight can increase a lot; Transmission progression is many, and total reliability also is affected, and these shortcomings all are bad factor concerning aircraft.Aircraft door upwardly opens mechanism's motor-driven deceleration force amplifier and partly requires to open about 1 minute about 100 degree, motor speed selects 1500 rpms, speed reducing ratio is greatly about more than 4000 like this, if adopt the combination of planetary gear spur gear and planetary gear to drive type, need at least 6 grades to drive with upper planet wheel, the gear that needs reaches about 30, and transmission sum of series part is many, and weight will increase a lot.
Summary of the invention
The object of the present invention is to provide the big aircraft door of few, the lightweight gearratio of a kind of number of spare parts to open or the locking driving mechanism.
A kind of aircraft door is opened or the locking driving mechanism, is characterised in that the drive form that adopts motor process worm screw and gear, planet circular system combination to slow down, and slows down with one-level worm and gear transmission realization is most of at least earlier; Regulate gearratio by gear drive again; Adopt planet circular system driving moment output shaft at last.
This programme adopts the drive form of worm screw and gear combination, mainly adopts worm speed-down, and requirement that can very fast realization big retarding ratio is accurately slowed down by gear again, just can be easy to reach gearratio more than several thousand.Simultaneously, self has auto-lock function worm screw, and mechanism any position in motion process can stop and latched position, and when being used for the retaining mechanism function, mechanism locking back just can keep locked position by auto-lock function.
The beneficial effect of this mechanism is to compare used spur gear and planetary gear combination driving, adopts main driving mechanism with worm speed-down, and transmission progression is few, and number of spare parts reduces, and used weight is relatively very light, and this is the factor of overriding concern to aeroplane performance.Worm mechanism is simple in structure, compact in design, and used space own is relatively very little, the transmission accuracy height of mechanism own.
Below in conjunction with the embodiment accompanying drawing this application is described in further detail.
Fig. 1 share the driving mechanism of opening in door for adopting two-stage worm screw and one-level planetary gear set.
Fig. 2 share in the tight driving mechanism of door lock for adopting one-level worm screw, one-level spur gear and one-level planetary gear set.
Fig. 3 is that the local A of Fig. 2 is to view.
Fig. 4 is that aircraft door opening mechanism and hatch door drive the force transmission shaft structural representation.
Fig. 5 is that aircraft door retaining mechanism and hatch door drive the force transmission shaft structural representation
1. motors among the figure, 2. worm screw, 3. worm gear, 4. second level worm screw, 5. second level worm gear, 6. planet circular system, 7. moment output shaft, 8. spur gear, 9. hatch door opening mechanism drive part, 10. hatch door retaining mechanism drive part.
The specific embodiment
For the specific design of aircraft door, the hatch door opening mechanism drives as shown in Figure 1, and opening mechanism requires to reach one fen clock time and rotates 100 degree requirements.In the enforcement, motor 1 adopts 1500 rev/mins of motor powers, 0.82 minute used time when output rotation 100 is spent.Concrete transmission process is that motor 1 drives worm screw 2, and worm screw 2 drives worm gear 3, and worm gear 3 drives worm screw 4, and worm screw 4 drives worm gear 5, and worm gear 5 drives planet circular system 6, and planet circular system 6 driving moment output shafts 7 reach the deceleration purpose.Adopt the two-stage worm-drive, because first order transfer torque is less, worm gear 3 numbers of teeth select 80, and number of threads selects 1, and gearratio is 80; Second level transfer torque is 80 times of the first order, and the worm gear diameter can not be too big, and worm gear 5 numbers of teeth 20 connect one group of planetary gear 6 transmission again, and gearratio is 3.5, and then finally reaching gearratio is 80 * 20 * 3.5=5600.Fig. 4 is that aircraft door opening mechanism 9 drives the force transmission shaft structural representation with hatch door, and the moment output shaft 7 that hatch door drives among force transmission shaft and Fig. 1 is a same force transmission shaft.
The hatch door retaining mechanism drives as Fig. 2, Fig. 3, Fig. 5, and the tight mechanism of door lock requires to reach in rotation in 10 seconds 120 degree requirements.Adopt 1500 rev/mins of motor powers, adopt the one-level worm-drive, worm gear 3 numbers of teeth 50, a number selects 1, and gearratio is 50; Spur gear 8 gearratios are 4, and planetary gear 6 gearratios are 5, and then finally reaching gearratio is 50 * 20=1000.12 seconds used time when then final output rotation 120 is spent.Concrete transmission process is that motor 1 drives worm screw 2, and worm screw 2 drives worm gear 3, and worm gear 3 drives straight-tooth wheels 8, and straight-tooth wheels 8 drive planet circular system 6, and planet circular system 6 driving moment output shafts 7 reach the deceleration purpose.Fig. 5 is that aircraft door retaining mechanism 10 drives the force transmission shaft structural representation with hatch door, and the moment output shaft 7 that hatch door drives among force transmission shaft and Fig. 1 is a same force transmission shaft.
