First cylinder lower surface is provided with a ramped shaped support member.
In above-mentioned body aluminium casting bearing, the base, frame and pillar are multiple by 3-d braided fiber/aluminium alloy
Condensation material is made.
Because the density of aluminium alloy is low, intensity is high, plasticity is good, so base, the frame of body aluminium of the present invention casting bearing
It is made with pillar of aluminum alloy materials and can solve the problem of traditional body aluminium casting bearing volume and weight is big, makes machine
Body aluminium casts bearing more lightweight, uses and carries and be more convenient.Moreover, aluminium alloy is cheap, body aluminium of the present invention can be reduced
Cast the production cost of bearing.
In addition, the present invention 3-d braided fiber preform is also pre-formed with aluminum alloy materials, using preform as
Enhancing skeleton forms a kind of laminated composite, is remarkably improved the performances such as intensity, the rigidity of aluminium alloy, has composite
Excellent shock resistance damage performance, mechanical property and ablation resistance, high comprehensive performance.
So base of the present invention, frame and pillar are made of 3-d braided fiber/Al alloy composite, can
To obtain high comprehensive performance, and the body aluminium casting bearing that light weight, cost are low.
In above-mentioned body aluminium casting bearing, 3-d braided fiber in the 3-d braided fiber/Al alloy composite
Percent by volume be 10-20%.Content is excessive or very few in the composite for 3-d braided fiber, does not have preferable increasing
Use is pretended, the combination property of composite is difficult to effectively improve.Therefore the present invention adds 10- based on aluminium alloy
20% 3-d braided fiber forms the preferable 3-d braided fiber/Al alloy composite of combination property, and for this is made
Invention body aluminium casts base, frame and the pillar of bearing, so as to obtain the product of excellent combination property.
In above-mentioned body aluminium casting bearing, the 3-d braided fiber is by carbon fiber, glass fibre, quartz fibre, height
One or more woven through three-dimensional full five-direction in silica fiber, aramid fiber forms.Three-dimensional full five-direction braiding refers in three-dimensional
Five increase axial yarn to the empty place of braiding preform, can so effectively eliminate the presence in axial room, manufactured three-dimensional
Full five-direction woven fibre material can effectively make up three-dimensional four-way, three-dimensional five to woven fibre material on axial property not
Foot.
In above-mentioned body aluminium casting bearing, the braid angle of the three-dimensional full five-direction braiding is 10-15 degree.The braiding of fiber
Angle is smaller, is more advantageous to the improvement of material property, and the braid angle of 10-15 degree can obtain 3-d braided fiber material in the present invention
Obtain the performances such as preferable bending strength.

The present invention with the addition of micro Sc elements in aluminium alloy, and Sc elements are both rare earth element and magnesium-yttrium-transition metal,
Its purification alloy in aluminium alloy with rare earth element, improve the effect of ingot structure and tying again for transiting group metal elements
Brilliant inhibitor effect, and action effect is more preferably.In addition, Sc elements can also form Al in aluminium alloy3Sc coherent precipitates have
There is extremely strong strong age-hardening effect.Therefore, addition Sc elements can improve the intensity of aluminium alloy, toughness, heat resistance, resistance to comprehensively
The performances such as corrosion.
In addition, the present invention also added Zr and Ti elements, Zr and Ti elements fall within transiting group metal elements, to aluminium alloy
The effect of structure refinement is only second to Sc, and still, price is cheaper than Sc, and compound addition can effectively reduce the cost of aluminium alloy.
Moreover, the Sc elements and Zr elements of the compound above-mentioned content of addition, especially, Zr and Sc mass percent sum 0.2%-
It is more strong that Zr-Sc cell configuration segregations are formed when 0.35%, Sc and Zr mass ratio ＜ 2, in aluminium alloy, easily separate out segregation
Particle, so as to be become apparent to matrix Al Grain Refinement Effects.
Further, since strong affinity between Mg and Ag be present, Ag of the present invention addition can improve the hard of aluminium alloy
Degree and intensity, while improve the plasticity of aluminium alloy, and delay the generation of overaging.But in the quality without Mg or Mg and Ag
Than not within the above range when, reinforcing effects of the addition Ag to aluminium alloy is smaller.Therefore, the control of Mg and Ag of the present invention mass ratio
Make extremely important.
