Abstract
The utility model is related to a kind of leading edge safeguard structures of alloy matrix aluminum blade, the leading edge of alloy matrix aluminum blade is provided with protection groove, it is bonded with shelter-clad on protection groove, and the thickness of shelter-clad is identical as the protection depth of groove so that does not form protrusion relative to the blade page in blade leading edge.The utility model reduces the maintenance times of blade, improves the service life of blade.
Description
Technical field：
The invention belongs to Design of Mechanical Structure, it is related to the blade leading edge safeguard structure struck by strong sandstone.
Background technology：
In a kind of propeller aluminium alloy blade of line, the particularity used due to it：High temperature, high humidity, high salt fog,
High rotating speed (linear velocity at blade tip position reaches 237.5m/s), and larger centrifugal force is born, what is blown afloat when propeller rotates is a large amount of
Silt particle and seawater generate intense impact and abrasion to blade leading edge.After using more than 100 hours, blade leading edge is different degrees of
Presence corrosion and injure, leading edge protection stainless steel bound edge there is partial disengagement, pit, blade tip position stainless steel bound edge, rubber
Cloth is worn, and damages serious phenomenon, and most deep pit depth reaches 4mm or more.It must adopt an effective measure, to improve blade leading edge
Anti- sandstone, the impact of seawater, abrasive capacity.
Invention content
The purpose of the present invention is：The protection of blade leading edge is improved, enhances the anti-exotic impact capacity of blade, to improve aluminium paddle
The service life of leaf.
Technical scheme of the present invention：
There is provided a kind of leading edge safeguard structure of alloy matrix aluminum blade, it is recessed that the leading edge of alloy matrix aluminum blade is provided with protection
Slot is bonded with shelter-clad on protection groove, and the thickness of shelter-clad is identical as the protection depth of groove so that
Blade leading edge does not form protrusion relative to the blade page.
Further, be bonded with rubber layer between protection groove and the shelter-clad, below preventing rubber layer face with
Groove bonding is protected, it is Nian Jie with nickel shelter-clad above rubber layer, and the overall thickness of preventing rubber layer and nickel shelter-clad
It is identical as the protection depth of groove so that not form protrusion relative to the blade page in blade leading edge.
Further, the shelter-clad material is stainless steel, nickel or titanium alloy.
Further, the protection groove reaches always blade tip from blade root.
Further, the nickel shelter-clad covers blade tip.
Further, the leaf tip is rounding shape, and protective cover is arc shape in leaf tip.
Further, the thickness of the rubber layer is 0.6~2.2mm.
Further, the thickness of the shelter-clad is 0.3~0.6mm.
The present invention operation principle be：The protection of aluminium blade leading edge is improved, while using high impact resistance and with elasticity
Rubber combined with metal hemming edge, improve the impact of blade leading edge anti-sandstone, abrasive capacity.
The advantages of the present invention：In the case where not changing thickness, the bullet of blade leading edge nickel bound edge is increased
Property, that is, increase its impact resistance.The further shape for optimizing blade blade tip, reduces the maintenance times of blade, improves
The service life of blade.

Specific implementation mode
The present invention is described in further details below.
There is provided a kind of leading edge safeguard structure of alloy matrix aluminum blade, it is recessed that the leading edge of alloy matrix aluminum blade is provided with protection
Slot is bonded with shelter-clad on protection groove, and the thickness of shelter-clad is identical as the protection depth of groove so that
Blade leading edge does not form protrusion relative to the blade page.
Further, be bonded with rubber layer between protection groove and the shelter-clad, below preventing rubber layer face with
Groove bonding is protected, it is Nian Jie with nickel shelter-clad above rubber layer, and the overall thickness of preventing rubber layer and nickel shelter-clad
It is identical as the protection depth of groove so that not form protrusion relative to the blade page in blade leading edge.
Further, the shelter-clad material is stainless steel, nickel or titanium alloy.
Further, the protection groove reaches always blade tip from blade root.
Further, the nickel shelter-clad covers blade tip.
Further, the leaf tip is rounding shape, and protective cover is arc shape in leaf tip.
Further, the thickness of the rubber layer is 0.6~2.2mm.
Further, the thickness of the shelter-clad is 0.3~0.6mm.
