Description
Technical field
The utility model belongs to technical field of aircraft structure design, and in particular to a kind of structure group that can eliminate gap automatically
Component.
Background technology
Monaural auricle, ears auricle and bearing pin are the common structures of fixed mechanism and motion on connection aircraft.So
And the fit precision between fixed mechanism and motion is more demanding：Interference volume is too big during cooperation, easily generates additional curved
Square；Clearance fit can make monaural auricle double swerve again.At present, it is typically all by improving zero to solve such installation matching problem
The part accuracy of manufacture, part manufacturing cost are high.
The content of the invention
The utility model passes through in order to solve the above technical problems, a kind of structural assemblies that can eliminate gap automatically of offer
The distance between bushing and single ears auricle are adjusted to ensure the installation accuracy between structure, is not only able to protection bearing pin, and
And gap can be eliminated automatically, and it is easy to operate, it is easy for installation.
The technical issues of in order to solve the utility model, the utility model are achieved through the following technical solutions：It is a kind of
The structural assemblies in gap can be eliminated automatically, including ears auricle 1, bushing A2, bushing B3, bushing C4, bushing D5, bushing E6,
Bearing pin 7, monaural auricle 8, adjusting gasket 9 and nut 10, the ears auricle 1 include the first auricle 11 and the second auricle 12,
The bushing A2 and bushing B3 is arranged between first auricle 11 and monaural auricle 8, and the bushing C4 and bushing D5 are set
Between 8 and second auricle 11 of monaural auricle；The bushing E6 is arranged between second auricle 11 and bearing pin 7,
The bearing pin 7 pass sequentially through bushing E6, the second auricle 12, bushing D5, bushing C4, monaural auricle 8, bushing B3, bushing A2 and
First auricle 11, the bearing pin 7 by the adjusting gasket 9 and nut 10 by the ears auricle 1, bushing A2, bushing B3,
Bushing C4, bushing D5, bushing E6 and monaural auricle 8 fasten；Gap L 1 is left between first auricle 11 and the bushing A2,
Ensure that ears auricle 1, bushing A2 and bushing B3 are compressed completely；Gap L 2 is left between the bushing B3 and bushing C4, ensures lining
B3, monaural auricle 8 and bushing C4 is covered all to compress；Gap L 3 is left between the bushing E6 and the second auricle 12, when bearing pin 7
When tightening, the gap L 3 between bushing E6 and the second auricle ensures bearing pin 7, bushing E6, ears auricle 1, bushing D5, bushing
C4 is compressed completely.The design of gap L 1, gap L 2 and gap L 3 ensures the cooperation essence of entire single ears auricle and bearing auricle
Degree.
Compared with prior art, the advantageous effect of the utility model acquisition is：
The utility model discloses a kind of structural assemblies that can eliminate gap automatically, passes through L1, gap L 2 and gap L 3
Design ensures entire ears auricle, the fit precision of monaural auricle and bearing auricle.By gap L 1, ensure bushing A and ears
Auricle compresses, and gap L 2 ensure that bushing B and bushing C will not cause auricle not press tightly axially because of interference.It is tightened in bearing pin
During, rigging error, by leaving gap L 3, ensures that bushing E and bushing D is held out against completely in order to prevent.Pass through bushing
It holds out against layer by layer, ensure that single ears auricle compresses completely, can not only transfer axle power, but also can solve opposite fortune with Transfer of Shear
The friction problem of movable property life.

Specific embodiment
Below in conjunction with the accompanying drawings, embodiment is described in detail.
Referring to attached drawing 1 and attached drawing 2, a kind of structural assemblies that can eliminate gap automatically, including ears auricle 1, bushing A2,
Bushing B3, bushing C4, bushing D5, bushing E6, bearing pin 7, monaural auricle 8, adjusting gasket 9 and nut 10, the ears auricle 1
Including the first auricle 11 and the second auricle 12, the bushing A2 and bushing B3 are arranged on first auricle 11 and monaural auricle 8
Between, the bushing C4 and bushing D5 are arranged between 8 and second auricle 11 of monaural auricle；The bushing E6 is arranged on institute
State between the second auricle 11 and bearing pin 7, the bearing pin 7 pass sequentially through bushing E6, the second auricle 12, bushing D5, bushing C4,
