Description
Technical field
The invention belongs to aeronautical and space technology is and in particular to a kind of electric steering engine null setting that can continuously adjust.
Background technology
Electric steering engine is simple due to small volume, light weight, structure, is increasingly used on Aerospace Products.?
In the design process of electric steering engine, and the neutral position length of steering wheel (when steering wheel is in zero-bit, fixing end earrings and outfan earrings
The distance of centre bore) it is an important parameter, designer should be designed according to the theoretical neutral position that user is given.But
When steering wheel is installed, often there is deviation in actual neutrality position with theoretical value, and therefore steering wheel structure allows for adjusting neutral position
Put, referred to as return to zero.In the null setting of conventional electric steering wheel, outfan earrings is connected with take-off lever by screw thread, by rotation
The displacement turning the generation of outfan earrings reaches the purpose adjusting steering wheel neutral position length.Because outfan earrings is limited by bearing
System, during zeroing, steering wheel needs to disassemble from bearing, troublesome poeration；In addition the anglec of rotation of outfan earrings is only
180 ° of integral multiple, leads to return to zero step-length for the 1/2 of connection screw thread pitch, precision is relatively low.
Content of the invention
The technical problems to be solved in the utility model：
Troublesome poeration and precision in order to solve the problems, such as the presence of conventional electric steering wheel null setting are low, and design is a kind of permissible
The mechanism of continuous zeroing is so that electric steering engine is dismantled during zeroing it is not necessary to from bearing, and possesses higher zeroing
Precision.
The technical solution of the utility model：
A kind of electric steering engine null setting that can continuously adjust, including take-off lever 1, outfan earrings 5, zeroing swivel nut 2,
Locking nut A3, locking nut B4, oscillating bearing 6, it is arranged on one end of take-off lever 1 of steering wheel, and outfan earrings 5 passes through
Screw thread is connected with zeroing swivel nut 2 endoporus, and take-off lever 1 is passed through screw thread and is connected with zeroing swivel nut 2 excircle, and locking nut A3 is screwed in tune
On zero swivel nut 2 external peripheral threads, locking nut B4 is screwed on outfan earrings 5 screw thread.Wherein oscillating bearing 6 is arranged on outfan
In earrings 5, take-off lever 1 opposite side is connected with fixing end earrings.
Zeroing swivel nut 2 endoporus and excircle all have screw thread, and the rotation direction of internal and external threads is identical but pitch is different.
In the rotary course of zeroing swivel nut 2, outfan earrings 5 is identical with the direction of motion of take-off lever 1, but displacement
Difference, the displacement difference of both motions is linear with the pitch difference of zeroing swivel nut 2 internal and external threads.
After steering wheel zeroing terminates, locking nut A3 and locking nut B4 twists towards take-off lever 1 and zeroing swivel nut 2 direction respectively
Tightly.
Principle of the present utility model be in traditional null setting increase by one zeroing swivel nut 2, this zeroing swivel nut 2 interior
Screw thread is all had on hole and excircle, the rotation direction of internal and external threads is identical but pitch is different.Outfan earrings 5 first with zeroing swivel nut 2
Female thread connect, then zeroing swivel nut 2 external screw thread be connected with take-off lever 1.Due to internal and external threads rotation direction with and pitch not
With, during rotation zeroing swivel nut 2, outfan earrings 5 and take-off lever 1 will produce displacement difference, and this displacement difference can be used for neutral position
Regulation, thus realizing continuous zeroing.Zero setting accuracy is then determined by the anglec of rotation of zeroing swivel nut 2 and the screw thread difference of internal and external threads
Fixed.
The beneficial effects of the utility model：
Have benefited from double thread structure, in zeroing, outfan earrings 5 does not need to dismantle from bearing steering wheel, only need to rotate tune
Zero swivel nut 2, you can continuous zeroing is realized by the moving displacement difference of swivel nut 2 internal and external threads that return to zero, simple to operate.Due to the spiral shell that returns to zero
Cover 2 anglec of rotation continuously adjustabe, zero setting accuracy is also obviously improved.
Brief description
Fig. 1 is the design structure diagram of this patent；
1- take-off lever, 2- zeroing swivel nut, 3- locking nut A, 4- locking nut B, 5- outfan earrings, 6- oscillating bearing
Specific embodiment
In conjunction with Fig. 1, describe technical solutions of the utility model in detail：
This structure comprises take-off lever 1, outfan earrings 5, zeroing swivel nut 2, locking nut A3, locking nut B4, joint shaft
Hold 6.
Oscillating bearing 6 is arranged in outfan earrings 5, and outfan earrings 5 is passed through screw thread and is connected with zeroing swivel nut 2 endoporus,
Take-off lever 1 is passed through screw thread and is connected with zeroing swivel nut 2 excircle, and locking nut A3 is screwed on zeroing swivel nut 2 external peripheral threads, locking
Nut B4 is screwed on outfan earrings 5 screw thread.
Zeroing swivel nut 2 endoporus mentioned above and excircle all have screw thread, and the rotation direction of internal and external threads is identical but pitch is different.
In the rotary course of zeroing swivel nut 2, outfan earrings 5 is identical with the direction of motion of take-off lever 1, but displacement is different, and two
The displacement difference of person's motion is linear with the pitch difference of zeroing swivel nut 2 internal and external threads.Zeroing swivel nut 2 anglec of rotation is bigger, then
Displacement difference is bigger, and vice versa.Because take-off lever 1 opposite side is connected with fixing end earrings, outfan earrings 5 and take-off lever
The displacement difference that 1 motion produces may serve as the regulation of the neutral position of steering wheel.Theoretically, as long as the rotation of zeroing swivel nut 2
Angle is sufficiently small, and the zero setting accuracy of steering wheel can level off to zero.In practical operation, by reducing zeroing swivel nut 2 internal and external threads
Pitch difference and the anglec of rotation of zeroing swivel nut 2, you can obtain higher zero setting accuracy.After steering wheel zeroing terminates, locking nut
A3 and locking nut B4 tightens towards take-off lever 1 and zeroing swivel nut 2 direction respectively, locking for structure.
