Description
Technical field
The utility model belongs to the aircraft control field, has been specifically related to a kind of electric steering gear based on linear potentiometers position feedback connecting link.
Background technology
In order to adapt to the steering wheel narrow space, the high requirement of steering wheel output shaft operating ambient temperature, steering wheel should have, and heat simple in structure, that the steering wheel axle is suffered is difficult for passing to the characteristics such as steering wheel potentiometer.To be mainly the potentiometer output shaft connected or the clearance elimination gear duplicate invoice connects with the steering wheel output shaft is direct insertion the position feedback link of steering wheel in the past.The steering wheel structure of straight cutting connecting mode is relatively simple, but, due to the impact in direct insertion gap, the position feedback precision of steering wheel is lower, to the servocontrol relative difficult of steering wheel; Connect and eliminated connection gap by the clearance elimination gear duplicate invoice, the servocontrol precision is high, but the space that this connecting mode of this kind needs is large, and complex structure, be unsuitable for the use at the narrow space steering wheel.When the steering wheel narrow space, during work, when the ambient temperature of steering wheel output shaft is very high, the temperature rise of steering wheel output shaft is fast, as adopts direct insertion connection or clearance elimination gear connection mode, the easy heat damage of potentiometer.
The utility model content
The utility model is in characteristics such as the inner space that takes into full account steering wheel and working environments, designed a kind of electric steering gear based on linear pattern potentiometer position feedback link, a steering wheel structure design difficult problem and integrity problem that solution is installed in small space, operating ambient temperature is high.The utility model is achieved in that
A kind of electric steering gear, comprise servomotor, idle wheel, servomotor gear, screw gear, screw mandrel, ut socket, connecting rod, steering wheel the output arm of force, steering wheel output shaft and potentiometer positioner and positioning key.
Servomotor drives screw mandrel to rotate by servomotor gear, idle wheel and screw gear successively; Described screw mandrel one end is fixedly connected with screw gear, and the other end is threaded with ut socket, and described screw mandrel is provided with ball bearing of main shaft, and described ut socket is provided with positioning key; The described ut socket other end is connected with the steering wheel output arm of force by connecting rod; Be fixed with the steering wheel output shaft on the described steering wheel output arm of force; The face that described steering wheel output shaft forms perpendicular to the steering wheel output arm of force and ut socket; Described ut socket is provided with potentiometer positioner and positioning key away from an end of steering wheel output shaft.
Described potentiometer positioner comprises linear potentiometers and potentiometer centre tap, and described potentiometer centre tap is threaded with the tapped bore on positioning key; Wherein, be the preferred WD14-42 type of linear potentiometers linear potentiometers.
Steering wheel adopts linear potentiometers, the potentiometer output shaft does not directly link with output shaft, and directly connect with the ut socket away from the steering wheel output shaft, make the suffered heat of steering wheel output shaft be difficult for being delivered to linear potentiometers in the operational use time at steering wheel, make not heat damage of linear potentiometers, thereby improved the reliability of steering wheel.
The linear potentiometers adapter shaft adopts the centre tap mode, adopts tapped potentiometer length direction installation dimension less, is convenient to be arranged in the steering wheel main casing, makes potentiometer away from steering wheel high-temperature zone (near the steering wheel output shaft).Simultaneously, the linear potentiometers centre tap directly is connected with the positioning key on ut socket, will be than adopting few two gears, the potentiometer locking mechanism etc. used of rotating potentiometer, and mounting structure is simple, and size is little.
The advantages such as the utility model adopts linear potentiometers as the position feedback link, and this kind of potentiometer slides the life-span more than 106, has environmental adaptability strong, and linear output accuracy is high, and volume is little, and mechanical attachment is simple, reliable.Reduced the quantity of driving parts in steering wheel design, reduced the difficulty of steering wheel design, improved the steering wheel reliability, and steering wheel volume, weight are dwindled greatly, thereby the volume, the weight that reduce whole rudder system make it meet technical requirements.
The accompanying drawing explanation
Fig. 1 is the utility model three-dimensional structure diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, in the present embodiment, electric steering gear comprises servomotor, servomotor gear 1, idle wheel 2, screw gear 3, screw mandrel 4, ut socket 5, connecting rod 6, steering wheel the output arm of force 7, steering wheel output shaft 8 and potentiometer positioner and positioning key 9.
During work, servomotor gear 1, idle wheel 2, screw gear 3 form the straight gear speed reduction gearing, and the high speed rotating of servomotor (not shown) is slowed down by motor gear 1, idle wheel 2, screw gear 3 successively; Connect motor gear 1 and screw gear 3 by idle wheel 2, can greatly save taking up room of straight gear speed reduction gearing.Screw gear 3 is fixed on screw mandrel 4 one ends, drives screw mandrel 4 and rotates, and screw mandrel 4 is fixing by ball bearing of main shaft 12 supportings.
The other end of screw mandrel 4 is threaded with ut socket 5, and ut socket 5 is provided with the positioning key 9 that limits its rotation, and positioning key 9 can be arranged in the chute of linear potentiometers 10.Under the restriction of positioning key 9, only allow ut socket 5 along its direction of axis line translation.When servomotor drives screw mandrel 4 rotation by the straight gear speed reduction gearing, screw mandrel 4 is done and is relatively rotated with ut socket 5, by positioning key 9, changes the rotation of screw mandrel 4 parallel motion of ut socket 5 along its axle center into; Here, screw mandrel 4, ball bearing of main shaft 12, ut socket 5 and positioning key 9 have formed the ball-screw retarder, form the second stage and slow down.
The other end of ut socket 5 is connected with the steering wheel output arm of force 7 by connecting rod 6, on the steering wheel output arm of force 7, is fixed with steering wheel output shaft 8; The face that steering wheel output shaft 8 forms perpendicular to the steering wheel output arm of force 7 and ut socket 5.When ut socket 5 translation, drive steering wheel output shaft 8 by connecting rod 6 and the steering wheel output arm of force 7 successively and move reciprocatingly, thereby finally drive steering wheel output shaft 8 as prescribed rotating speeds to realize the angle rotation, and export corresponding torque.
The potentiometer positioner is arranged on the end of ut socket 5 away from steering wheel output shaft 8, comprises WD14-42 type linear potentiometers 10 and potentiometer centre tap 11, and potentiometer centre tap 11 is threaded with the tapped bore on positioning key 9.Ut socket 5 is done drive linear potentiometers centre tap 11 in the straight reciprocating motion process and is done straight reciprocating motion simultaneously, thereby change the numerical value of linear potentiometers, the linear potentiometers motion changes the angular signal of steering wheel output shaft the Voltage-output signal of linear potentiometers into for controlling the angle position of steering wheel output shaft.
