Embodiment
A kind of embodiment of 1, the 2 description present invention below in conjunction with the accompanying drawings.
For double remaining dynamoelectric accelerograph mechanisms in automatic control system, there is housing 1 and mounting seat 6, the housing 1 by
Upper shell 2, main casing 3 and lower house 4 form and housing 1 is flexible even in band damping by bikini damper 5 and mounting seat 6
Connect, bikini damper 5 can be reduced and angular movement is added caused by vibration, and double remaining motors, double remainings are provided with the housing 1
Angular transducer and clutch 9, and gear I 10 and gear II 11 are equipped with the output shaft of double remaining motors, specifically, described
Double remaining motors include brushless electric machine 7 and brush motor 8, and the gear I 10 and gear 11 II are separately fixed at brush motor 8
On the output shaft of brushless electric machine 7, the gear I 10 and gear II 11 are respectively by crossing gear train I 12 and crossing gear train II 13
It is connected with the backgear circle 15 on clutch 9 and nipper wheel rim 16, the backgear circle 15 and nipper wheel rim 16 are fastened on respectively
On the rear tooth disk 17 and preceding fluted disc 18 of clutch 9, the output shaft of active toothed disk 19 and harmonic speed reducer 20 on the clutch 9 connects
Connect and active toothed disk 19 is placed between rear tooth disk 17 and preceding fluted disc 18, harmonic speed reducer 20 is fixedly mounted on main casing 3 by screw
Locating surface on, and clutch location-plate is arranged on main casing 3, to the bearing holder (housing, cover) of fixed rear tooth disk 17, the preceding fluted disc
18 are provided with permanent magnet.Preceding axle envelope 21 and rear shaft seal 22 are separately fixed on lower house 4 and mounting seat 6, and preceding axle envelope 21 is with after
Axle envelope 22 is connected with shaft coupling prosthomere 23 and shaft coupling deutomerite 24 respectively, the shaft coupling prosthomere 23 and shaft coupling deutomerite
Shaft coupling coupler 25 and shaft coupling prosthomere 23 is provided between 24, shaft coupling deutomerite 24 and shaft coupling coupler 25 is serially connected in output shaft 14
On.The preceding axle envelope 21 and rear shaft seal 22 are that resistant to elevated temperatures polytetrafluoroethylene (PTFE) is made and preceding axle envelope 21 and rear shaft seal 22 are built-in with footpath
The spring turned to the thin slice of pretightning force, it can maintain to seal and provide wear-compensating.The clutch 9 is that dibit toothed disc type is high
Fast Miniature clutch.
This structure electric accelerator mechanism mainly includes brushless electric machine 7, brush motor 8, clutch 9, the and of harmonic speed reducer 20
Double remaining angular transducers, used suitable for unmanned plane, when being such as used for manned, then concatenation one is low on output campaign part
Speed is carried and electromagnetic clutch and definite value friction slip clutch, as pilot steering and the switching of automatic Pilot, in operation, when
When brushless electric machine 7 is detected faulty, instruction is sent by control system, clutch is powered, brushless electric machine 7 is released, and connects
Standby motor is that brush motor 8 is operated, and the angle displacement of accelerator mechanism is by the output shaft of harmonic speed reducer 20 in this structure
Realize, because brushless electric machine 7 and the small volume rotating speed of brush motor 8 are higher, and the output of accelerator mechanism is dead slow speed rotation, between
Speed reducing ratio mainly realized by harmonic speed reducer 20.The output shaft angle precision of harmonic speed reducer 20 is very high, and error is generally small
In 6 jiaos points and it is easily achieved 3 jiaos points, is strict with and can be achieved to be less than 1 jiao point.And gear reduction unit, only final-stage gear sideshake
Caused by idle running error, usually 30~40 jiaos points.The not only small volume of harmonic speed reducer 20, for ambient vibration, it does not ring
Structure is answered, also not transferring structure, but realize dissipative structure, it is in light weight, and because work faying face is big, movement parts quality
It is small, under the conditions of high vibration, stronger absorption and dissipation effect is presented to being harmful to energy, therefore, vibration resistance is strong, due to work
Make contact surface makes stress value low and is evenly distributed greatly, therefore wear-resistant long lifespan；Because angular transducer belongs to winding
Electromechanical compo, compared with mechanical part, reliability is relatively low.Therefore using double remaining angular transducers.Electric throttle actuating mechanism
In, all electric insulations and sealing and nonmetal parts have all selected exotic material, can be at 220 DEG C and short-term with long-term work
300 DEG C, thus suitable for this product is nearby worked mounted in engine；To adapt to the high vibration environment near engine, this knot
The core of structure by support on the built-in damper with very high flexibility and with frictional damping, meanwhile, output shaft 14 and quilt
Between the connection of control throttle, have six from degree shaft joint, it is one of free to accommodate the motion of the mutual dislocation under vibrational state
Spend for angle displacement.
To adapt to work under judder occasion, core component brushless electric machine 7, the harmonic reduction of 8 clutch of brush motor 9
Device 20, double remaining angular transducers all in the housing 1 with some strength of sealing, vibrate relative position in order to tolerant
Moving, output shaft 14 concatenates shaft coupling prosthomere 23, shaft coupling coupler 25 and the shaft coupling deutomerite 24 of six degree of freedom, one of them is certainly
Angle displacement is rotated by spending.Shaft joint prosthomere 23 coordinates with preceding axle envelope 21, between keep rotatable sealing state, front axle
On the lower house 4, shaft joint deutomerite 24 coordinates envelope 21 with rear shaft seal 22, between keep rotatable sealing state, rear shaft seal 22
In mounting seat 6, when in judder state, vibration displacement together with output displacement under the conditions of six degree of freedom is tolerant,
Make bump stress will not occur between each parts, and to output corner without idle running error.Brushless electric machine 7 and brush motor 8
It is separately mounted to the diverse location of main casing 3, gear I 10 and gear II 11 on the output shaft of brush motor 8 and brushless electric machine 7
