Description
Technical field
The invention belongs to aero-engine structure-design technique fields, and in particular to one kind is spiraled suitable for circular arc end gear
Turn the simplification connection structure of experiment.
Background technology
The experiment of aero-engine wheel disc is carried out mostly on spin test facility, it is desirable that each connector of wheel disc testpieces should
Connection is reliable, centering is good.At present, it when aero-engine circular arc end tooth wheel disc makees rotation test, needs through band circular arc end tooth
The group section of coupling structure is connected thereto, and realizes circumferential torsion pass and radial centering effect.But there are techniques for circular arc end tooth processing
It is required that the features such as high, the process-cycle is poor so that the processing cost and time cost of group section are higher, are brought to wheel disc rotation test
It is difficult.
Invention content
Goal of the invention：The present invention proposes new structural solutions for circular arc end tooth wheel disc, by being set in Coupling Shaft
Count two radial direction seam allowances so that circular arc end tooth wheel disc radial positioning, then by elastic component axial compression so that circular arc end tooth wheel disc
Axially position and circumferential torsion pass are reliable, so as to ensure that rotation test of the circular arc end tooth wheel disc on spin test facility is able to smoothly
Implement.
Technical solution：The present invention realizes the linkage function of testpieces and slewing, structure of the invention by Coupling Shaft
It is made of Coupling Shaft 1, circular arc end tooth wheel disc 2, elastic component 3, big nut 5 and locking plate 6；Coupling Shaft 1 designs two radial direction seam allowances,
Circular arc end tooth wheel disc 2 is made to be limited by the first Coupling Shaft seam allowance 1a centering and the second Coupling Shaft seam allowance 1b, by 5 compression axis of big nut
Locked to positioning, and with locking plate 6, ensure that axial connection is reliable axially through the flexible deformation of elastic component 3, reach it is simple, can
The connection structure leaned on.
Further, the parameter of the first Coupling Shaft seam allowance 1a totally 2：Diameter phi A, length E, positioned at circular arc end gear
The inside of 2 seam allowance of disk, the first Coupling Shaft seam allowance 1a are designed as being interference fitted so that circular arc end tooth wheel disc 2 is in rotation test process
It still can effective position.
The parameter of the second Coupling Shaft seam allowance 1b shares 4：Diameter phi B, depth C, thickness D and angle [alpha], positioned at wheel disc
The outside of circular arc end tooth structure, the second Coupling Shaft seam allowance 1b is designed as clearance fit, first, can improve the work of circular arc end tooth wheel disc 2
It feels relieved, second is that the vibration stress of entire rotor can be reduced.
In order to which power that elastic component 3 is transferred to big nut 5 is uniform, pressing plate 4 is set therebetween, being transmitted with dispersion should
Power.
Again by adjusting the rigidity of elastic component, decrement is rationally set so that circular arc end tooth wheel disc turns in entire experiment
Axial compression in fast range, and there is no critical speeds, are smoothly completed with guarantee test.
Advantageous effects
The present invention realizes circular arc end tooth wheel disc radial positioning, then by elastic component axis by two radial direction seam allowances of Coupling Shaft
It realizes that axially position and circumferential torsion pass are reliable to compressing, ensures that the rotation test of circular arc end tooth wheel disc is smoothly implemented.This hair
It is bright to be especially used in the common circular arc end tooth wheel disc of aero-engine.By the switching Axile connection structure of this design, avoid
The problems such as period of Machining Arc end tooth Coupling Shaft is long, of high cost also solves the unreliable caused vibration of Coupling Shaft positioning and asks
Topic.

Specific embodiment
Referring to attached drawing 1-3, structure of the invention is by Coupling Shaft 1, circular arc end tooth wheel disc 2, elastic component 3, pressing plate 4, big spiral shell
Mother 5 and locking plate 6 form.Coupling Shaft 1 designs two radial direction seam allowances, and circular arc end tooth wheel disc 2 is made to determine by the first Coupling Shaft seam allowance 1a
The heart and the second Coupling Shaft seam allowance 1b limitings compress axially position, locking plate locking, axially through the bullet of elastic component 3 by big nut
Property deforms guarantee, and axially connection is reliable, reaches simple, reliable connection structure.
By 2 structural parameters of circular arc end tooth wheel disc, the diameter A of Coupling Shaft 1, the basic size of diameter B, C, E can be obtained,
Its fit tolerance is determined further according to the requirements such as reliable, well-located are connected, and the size of D, a is by experiment spin load and Coupling Shaft
Safety etc. is comprehensive to be determined.By determining 2 parameters of the first Coupling Shaft seam allowance 1a and limiting the second Coupling Shaft seam allowance 1b's
4 parameters so that circular arc end tooth wheel disc 2 had not only been avoided that vibrated big problem under rotation test, but also will not increase additional load,
Under the stress distribution for not influencing circular arc end tooth wheel disc 2, really play the role of limiting, ensure that circular arc end tooth wheel disc 2 revolves
Turn the accuracy of experiment.
Again by adjusting the rigidity of elastic component, decrement is rationally set so that circular arc end tooth wheel disc turns in entire experiment
Axial compression in fast range, and there is no critical speeds, are smoothly completed with guarantee test.
The present invention realizes the connection of testpieces and testing equipment by the Coupling Shaft of two radial direction seam allowances of band, so as to ensure to justify
Rotation test of the arc end tooth wheel disc on spin test facility is smoothly implemented.The structure has novelty, during structure design
Not only simplified the connection of Coupling Shaft and circular arc end tooth wheel disc, but meet wheel disc rotation test part connection it is reliable, centering is good,
Many requirements such as the operation is stable.At present, which has applied the excess revolutions bursting strength test of Mr. Yu's engine high pressure turbine disk, examination
Verify that the bright designing scheme is feasible.
