Description
Technical field
Shaft core technical field is the utility model is related to, specially a kind of corrosion-resisting aluminium shaft core.
Background technology
Shaft core is commonly used in rotating machinery, and he can ensure the coaxial relation of connected part well, and due to shaft core
End is locked when having screw thread or screw hole to connect shaft core, the shaft core and be preferably to protect the advantages of set that it is connected than part
The concentric of part that be connected is demonstrate,proved, but because shaft core is usually overall transmission moment of torsion, therefore shaft core can not transmit too big moment of torsion, easy damage
Bad, the necessary hardness of shaft core material is strong, the shaft core for using aluminium to form, if less strict to aluminium requirement for anticorrosion, aluminium
Just there is layer protecting film once producing surface, general protective effect but strict to aluminium requirement for some can be played,
But if using precision, that must just carry out fine processing so that the fine and close protective layer of aluminium generation, shaft core be protected
Shield.
Utility model content
The purpose of this utility model is to provide a kind of corrosion-resisting aluminium shaft core, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of corrosion-resisting aluminium shaft core, including shaft core master
Body, connection end, aluminium core, back-up coat and fixed end, the shaft core main body are made up of aluminium core and back-up coat respectively from inside to outside,
And aluminium core both ends are respectively fixed with connection end and fixed end, the connection end other end is welded with connection anti-drop block, and
Anti-slip veins are provided with outside connection end, the fixed end top is provided with fixing groove, and is offered inside fixed end solid
Determine hole, insoluble network layers altogether are provided with outside the connection end, aluminium core, back-up coat and fixed end, and outside insoluble common network layers
Portion is provided with anodic oxide coating, covered with electrophoretic painting layer outside the anodic oxide coating.
Preferably, the connection end, back-up coat and fixed end are made of aluminum component.
Preferably, the connection end and fixed end with aluminium core by being welded and fixed.
Preferably, internal thread is offered in the fixing hole.
Compared with prior art, the beneficial effects of the utility model are：Shaft core main body is made up overall strong of aluminum core material
Degree is high, and back-up coat can increase shaft core bulk hardness, service life length, and the fixing groove in fixed end and fixing hole are by shaft core master
Body is fixed on rotating mechanism, and rotating mechanism drives shaft core body rotation, by anti-slip veins outside connection end with being connected anticreep
Block makes that connection end connection is compact, and stability is high, prevents from coming off, outside connection end and fixed end, aluminium core and back-up coat according to
Insoluble network layers, anodic oxide coating and the electrophoretic painting layer altogether of secondary setting make possess high anti-corrosive properties outside aluminium shaft core, anti-corrosive properties effect
It is good, increase shaft core main body service life.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is top view of the present utility model.
