Description
Technical field
The invention belongs to Inspection Aircraft Wheels design fields, are related to a kind of wheel hub interface structure.
Background technology
With the continuous improvement that modern aircraft wheel life requires, opposite opened structure airplane wheel is increasingly used in
The main wheel of domestic military secret and civil aircraft, especially preceding wheel and civil aircraft mostly uses greatly opposite opened structure.By to domestic a variety of right
The statistics at open type wheel hub fatigue fracture position finds most opposite opened structure wheel hub fracture locations in wheel
At the bolt of wheel hub.Further analysis finds that the country uses the airplane wheel wheel hub interface of opposite opened structure flat for two
Face connects, and two planes are bonded completely, simple in structure.
Invention content
The purpose of the present invention is：For the fatigue strength for improving at existing opposite opened structure airplane wheel boss bolt aperture,
The fatigue stress reduced at boss bolt aperture is horizontal, and the present invention proposes a kind of airplane wheel wheel hub docking of low stress level
Face structure.
The technical scheme is that：A kind of wheel hub interface structure, including interior half wheel hub interface, outer half wheel hub
Interface and to connecting bolt；Half wheel hub interface is a concave ball surfaces in described, is that half wheel hub docks in plane in routine
A spherical surface is formed by mechanical processing at bolt hole；Outer half wheel hub interface is also a concave ball surfaces, is docked with interior half wheel hub
Face structure is identical；Interior half wheel hub interface and outer half wheel hub interface are full symmetric, are bolted to form one by docking
A enclosed construction.
Further, the spherical radius be SR200~300mm, spherical surface docked with wheel hub plane knuckle for R10~
R15mm.Global minima is H0.5~1mm at a distance from docking plane.
When beneficial effects of the present invention：The portion that the present invention passes through one major diameter of processing inside and outside half boss bolt aperture
Bulb separation face makes to become contactless state from original contact condition inside and outside half boss bolt aperture.Reduce tools for bolts ' pretension
When, the stress level at bolt fillet is horizontal to reduce fatigue stress inside and outside half boss bolt aperture, carries
The high bulk life time of wheel hub.
Description of the drawings
Fig. 1 is a kind of wheel hub interface structural schematic diagram；
Fig. 2 is interior half wheel hub interface structural schematic diagram；
In figure：
Half wheel hub in 1.；2. outer half wheel hub；3. pair connecting bolt.
Specific implementation mode
The specific implementation mode of the present invention is described further below in conjunction with the accompanying drawings.
This example is used for aircraft wheel assemblies.
As shown in Figure 1, interior half wheel hub 1 and outer half wheel hub 2 that the present embodiment proposes are to be assemblied in one by connecting bolt 3
It rises, interior half wheel hub, 1 interface and outer half wheel hub, 2 interface form an enclosed construction by being connected to connecting bolt 3.
As shown in Fig. 2, interior half wheel hub interface shape is a concave ball surfaces, concave ball surfaces radius SR is 200mm, spill ball
Between face minimum point docks plane with wheel hub distance H be 0.5mm, concave ball surfaces dock plane with wheel hub between knuckle R
For 10mm.
As shown in Figure 1, outer half wheel hub interface is also a concave ball surfaces, it is identical with interior half wheel hub interface structure.
It is bolted to form an enclosed construction by docking.
It is big straight by processing one inside and outside half boss bolt aperture when tools for bolts ' pretension and wheel bear fatigue load
Diameter spherical surface makes have original contact condition to become contactless state inside and outside half boss bolt aperture, reduces tools for bolts ' pretension
When, the stress level at bolt fillet, to reduce the fatigue stress inside and outside half boss bolt aperture.Certain type flies
After machine is by wheel hub interface structural modification, fatigue lives of wheel assemblies rises and falls raising to 6000 or more by 2000
It falls, shows that the structure can improve the fatigue life at bolt, and then improve the fatigue life of wheel hub.
