Description
Technical field
This utility model belongs to strength of aircraft design field, particularly relates to a kind of anti-out-of-plane bending connector.
Background technology
The concentrfated load of aircraft widely used auricle type of attachment transmission at present, auricle structure type of attachment is simple,
General bearing plane internal load.As aircraft structure uses auricle bolt to connect transmission concentrated moment, see Fig. 1.
Connector 1' is connected with structural member 4', and connector 1' couple M is passed by bolt 3', auricle 2' contact form
Passing, connector 1' reaches the moment of auricle 2' has two ways to balance: earhole is squeezed by mode one by bolt 3'
The equilibrium of couples that pressure effect counter-force F1-F1 is formed, mode two is by connector 1' and upper and lower auricle extruding force
The equilibrium of couples that F2-F2 is formed, equalising torque schematic diagram is shown in that Fig. 2, auricle stress F1 are tension and compression load in face
Lotus, power F2 is face external applied load for auricle structure.Under F2 effect, auricle root bending stress is the highest.
But certain model limits and special development demand for space, auricle is subjected in face outside tensile load and face
Load, the moment of flexure that face external applied load causes makes auricle local stress significantly improve, for preventing auricle due to intensity
Not enough and destroy, auricle 2' and structural member 4' is forced the heavier of design, and connector 1' is the biggest, pays bigger
Weight cost.
Utility model content
The purpose of this utility model is to provide a kind of anti-out-of-plane bending connector, solves the problems referred to above.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of anti-out-of-plane bending connects
Part, is used for making upper and lower auricle in auricle attachment structure be subjected only to loads in plane, it include auricle, connector,
Connecting bolt and locking nut, be provided with the step of depression, and described ledge surface in the middle part of described connecting bolt
Smooth, connector is placed in described step, and described connecting bolt is through two symmetrical auricles and connector
And lock with locking nut, connector and upper and lower auricle have gap.
Further, described connector includes that body and splice, body and splice all have half slot,
And body and splice splice latter two half slot and are formed in circular hole, the diameter of described circular hole and connecting bolt
Diameter at portion's step is identical, and circular hole coordinates with step, and body is bolted with splice
Connect.
Further, also has changeover portion at described connecting bolt step.
Further, described changeover portion is chamfering.
Further, described chamfering is rounding.
One of the present utility model anti-out-of-plane bending connector is placed in connecting bolt by connector, and makes
Gap it is provided with so that auricle out-of-plane bending load is converted into Tensile or Compressive Loading in face between connector and auricle,
And then load can only reduce structural stress level with the form transmission of tension and compression in face, alleviate construction weight.
