Abstract
The present invention relates to a kind of leading edge safeguard structure of alloy matrix aluminum blade, the leading edge of alloy matrix aluminum blade is provided with protection groove, shelter-clad is bonded with protection groove, and the thickness of shelter-clad is identical with protecting the depth of groove so that does not form protrusion relative to the blade page in blade leading edge.The present invention reduces the maintenance times of blade, the service life of blade is improved.
Description
Technical field：
The invention belongs to Design of Mechanical Structure, is related to the blade leading edge safeguard structure impacted 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, intense impact and abrasion are produced 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 more than 4mm.It must adopt an effective measure, to improve blade leading edge
Anti- sandstone, the impact of seawater, abrasive capacity.
The content of the invention
The purpose of the present invention is：The protection of blade leading edge is improved, strengthens the anti-exotic impact capacity of blade, so as to improve aluminium paddle
The service life of leaf.
Technical scheme：
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
Groove, is bonded with shelter-clad on protection groove, and the thickness of shelter-clad is identical with protecting the depth of groove so that
Blade leading edge does not form protrusion relative to the blade page.
Further, be bonded with rubber layer between the protection groove and 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 gross thickness of preventing rubber layer and nickel shelter-clad
Depth with protecting groove is identical so that does 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 blade tip always from blade root.
Further, the nickel shelter-clad covering 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 added
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.

Embodiment
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
Groove, is bonded with shelter-clad on protection groove, and the thickness of shelter-clad is identical with protecting the depth of groove so that
Blade leading edge does not form protrusion relative to the blade page.
Further, be bonded with rubber layer between the protection groove and 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 gross thickness of preventing rubber layer and nickel shelter-clad
Depth with protecting groove is identical so that does 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 blade tip always from blade root.
Further, the nickel shelter-clad covering 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.
