Abstract
The invention discloses a copper sleeve which comprises a copper sleeve body. The copper sleeve body is of a cylindrical structure. A through hole is formed in the middle of the copper sleeve body in the axial direction. The copper sleeve body is composed of an inner layer and an outer layer. The inner layer is made of copper alloy materials, and the outer layer is made of steel materials. The copper sleeve is simple in structure and easy to achieve. The copper sleeve is composed of the inner layer and the outer layer, the inner layer is made of the copper alloy and the outer layer is made of the steel materials, so that compared with a pure copper sleeve, requirements for wear resistance and various properties are met, raw copper materials are saved, and production cost is effectively reduced.
Description
Technical field
The present invention relates to a kind of copper sheathing.
Background technique
Copper sheathing as a kind of component, extensive use in mechanical field, it is used as axle sleeve, and that rotating shaft can be made to coordinate with bearing, frame etc. is compacter, can be good at protection rotating shaft simultaneously, the working life of raising rotating shaft; But metallic copper is as a kind of non-renewable resources, day by day deficient, be the less rare heavy metals of reserves, price is higher, and existing copper sheathing is all be made up of Cuprum alloy, and production cost is higher.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of copper sheathing is provided, to solve the higher problem of existing copper sheathing cost of production.
The object of the invention is to be achieved through the following technical solutions:
A kind of copper sheathing, comprise copper sheathing body, described copper sheathing body is cylindrical structural, and its middle axially has through hole, and copper sheathing body is made up of internal layer and skin, and described internal layer is made up of Cu alloy material, and described skin is made up of Steel material.
Further, described skin is made up of stainless steel material.
Further, described internal layer and skin fuse into integrative-structure by sintering.
Beneficial effect of the present invention is, described a kind of copper sheathing structure is simple, be easy to realize, it is made up of internal layer and skin, and internal layer is made up of Cuprum alloy, and skin is made up of Steel material, compared with existing fine copper cover, both met the requirement in wear-resisting and various performance, and in turn saved copper raw material, effectively reduce cost of production.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of copper sheathing of the present invention.
In figure:
1, outer; 2, internal layer.
Embodiment
Technological scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of a kind of copper sheathing of the present invention; In the present embodiment, a kind of copper sheathing, comprise copper sheathing body, described copper sheathing body is cylindrical structural, its middle axially has through hole, and copper sheathing body is made up of internal layer and skin, and described internal layer is made up of Cu alloy material, described skin is made up of stainless steel material, and described internal layer and skin fuse into integrative-structure by sintering.
The present invention is rational in infrastructure, and its internal layer is made up of Cu alloy material, stable performance, can meet usage requirement, and its outer stainless steel material that adopts is made, and reduces cost of production, can replace existing fine copper cover, economical and practical.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention does not limit by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
