Description
Technical field
The present invention relates to torsion component, and in particular to a kind of unmanned plane oar folder connection torsion piece component.
Background technology
It is many excellent that plant protection unmanned plane has exclusive low cost, low-loss, zero injures and deaths, reusable and height motor-driven etc.
Gesture, is agriculturally playing huge effect, for example：Sowing, sprinkling, insect prevention etc..The rotor part of plant protection unmanned plane is for nobody
The important component of helicopter, existing plant protection unmanned plane oar folder with Zhu Jiang bindiny mechanisms is passed through respectively using two of axle
Bearing and oar are pressed from both sides axial restraint by bearing with bolt again, and this structure has following defect：
1）Tensile strength is low, and the produced huge centrifugal force in flight course of aircraft has the risk for coming off by oar folder；
2）Fatigue resistance is low；
3）It is antitorque using bearing, it is less economical.
The content of the invention
Goal of the invention：In view of the shortcomings of the prior art, the present invention provides a kind of unmanned plane oar folder connection torsion piece component, tool
There are stronger tension, anti-twisting property.
Technical scheme：Unmanned plane oar of the present invention folder connection torsion piece component, including some groups be cascading
Torsion piece and torsion piece pad；The torsion piece is included located at middle for connecting the first through hole of unmanned owner's oar, located at two
Two sections of list structures for connecting the second through hole of unmanned plane oar folder and be connected between first through hole, the second through hole are held,
The second through hole center deviation first through hole center at the torsion piece two ends causes that the second through hole is connected with the center of first through hole
Line has deflecting angle relative to first through hole central horizontal line, and the number of degrees of deflecting angle are 0.8 ° ~ 2.2 °；The first of the torsion piece
Through hole, the second through hole are correspondingly provided with the torsion piece pad.The V-type angle of torsion piece is that angle is determined by many factors
Fixed, such as aircraft deadweight, engine power and aircraft blade takes off the centrifugal force of generation, is drawn a conclusion through test of many times, company
The deflecting angle for connecing oar folder torsion piece used is the controllable angle scope of aircraft stabilized flight at 0.8 ° ~ 2.2 °, if deflecting angle is small
In 0.8 °, then the shearing force increase suffered by the transverse axis of torsion piece is carried, while transverse axis has risk of breakage, if deflecting angle is more than
2.2 °, then the load increase that engine bears, aircraft load-carrying reduction.And 1.6 ° is then best angle, suffered by balance torsional piece
Optimal state is reached during the load of shearing force and engine.
Above-mentioned technical proposal is further improved, the first through hole, the second through hole are tapped through hole, by bolt and institute
Unmanned owner's oar, unmanned plane oar folder is stated to be respectively connected with.Normally make by the torsion piece component bolt is fixed with oar folder, main oar
With, it is easy for installation, it is simple using process.
Further, the torsion piece pad is and the tapped through hole structure identical thin rounded flakes.
Further, the thickness of the torsion piece is 0.05mm ~ 0.2mm.Further preferably, the thickness of the torsion piece
It is 0.1mm.
Further, the thickness of the torsion piece pad is 0.05mm ~ 0.2mm.Further preferably, the torsion piece pad
Thickness be 0.1mm.
Further, the torsion piece and torsion piece pad are made of 304 stainless steels, with antitorque and anti-well
Fatigue behaviour,
Beneficial effect：Compared with prior art, advantages of the present invention：Using the present invention connection oar press from both sides and main oar, with compared with
Strong tension, anti-twisting property, main oar can be resisted in the flight course of unmanned plane and rotates the powerful pulling force come to oar entrainment；Together
When in the lifting process of unmanned plane, after oar folder rotates a certain angle, under the control without external force, it is automatic that torsion piece can allow oar to press from both sides
Return, with it is antitorque the characteristics of, without increasing a set of oar folder return control system；It is the stainless steel thin slice of 0.1mm to use thickness
It is made, with good antitorque and anti-fatigue performance；Unmanned plane is born by torsion piece and torsion piece pad stacked combination to fly
Pulling force during row, modulability is high, presss from both sides the maximum centrifugal force for rotating by unmanned plane oar to judge to need how many groups of torsion pieces and torsions
Power piece pad, without redesigning overall structure, effectively save cost.

Specific embodiment
Technical solution of the present invention is described in detail below by accompanying drawing.
Embodiment 1：Unmanned plane oar folder connection torsion piece component as shown in Figures 1 to 4, including 30 groups be cascading
Torsion piece 1 and torsion piece pad 2, every group includes a torsion piece 1 and three torsion piece pads 2；Torsion piece 1 is for thickness
0.1mm thick thin slice, is provided with first through hole 12, two ends and is provided with the second through hole 11 therebetween, the center deviation of the second through hole 11 the
The center of one through hole 12 causes the central junction line of the second through hole 11 and first through hole 12 relative to the central horizontal line of first through hole 12
With deflecting angle, the number of degrees of deflecting angle are 1.6 °.First through hole 12, the second through hole 11 are tapped through hole, torsion piece pad 2 with
First through hole 12, the structure of the second through hole 11 are identical and are correspondingly arranged therewith.Torsion piece pad 2 is that thickness is the circular thin of 0.1mm
