Abstract
The utility model discloses a high-strength steel-based copper alloy shaft sleeve with a flange. The high-strength steel-based copper alloy shaft sleeve comprises a steel-based outer layer; one end of the steel-based outer layer is provided with the flange. A copper alloy layer is combined on the internal surface of the steel-based outer layer by means of atomic exchange; the copper alloy layer continuously extends from the internal surface of the steel-based outer layer to the whole end face of the flange; an axial groove is evenly distributed on the combination face of the steel-based outer layer and the copper alloy layer; an oil groove is arranged on the internal surface of the copper alloy layer; the oil groove is a helix groove; and solid lubricant is embedded into the oil groove. The high-strength steel-based copper alloy shaft sleeve with the flange has the advantages of strong impact resistance of the steel-based outer layer as well as the advantages of the thermal conductivity and the wear resistance of the copper alloy layer; particularly, the high-strength steel-based copper alloy shaft sleeve with the flange has the structure with the oil groove and the embedded solid lubricant, so that when the bearing works, even if the oil is run out, the friction coefficient is reduced due to a layer of shift film formed by the solid lubricant through frictional heat; therefore, the phenomenon of shaft hinge is avoided.
Description
Technical field
The utility model relates to a kind of axle sleeve, relates in particular to a kind of flanged (FLGD) high strength steel base Cuprum alloy axle sleeve.
Background technique
At present, in the mechanical industry at home,, adopt integrated type copper sheathing or integrated type steel bushing usually to guideway that reciprocatingly slides or the axle sleeve that rotates.The thermal conductivity and the antifriction quality of copper sheathing are better, but have bearing capacity poor, the shortcoming of shock resistance difference.Steel bushing is then opposite, and shock resistance is strong, bearing capacity is big, but poor thermal conductivity, and when hardness was higher, as the axle to the mill part, its wearing and tearing were very fast and " sting axle " easily.For this reason, some producer has adopted at the outer field internal surface of base steel, sintering one deck copper powder or be coated with, plate the method for layer of copper.But the axle sleeve that obtains thus, the combination force of steel and copper is very poor, and actual measurement is not more than 16MPa; And the compactness of copper powder layer is poor, and promptly density is low, the anti scuffing ability weak, bearing capacity is little, carries in the machinery of middling speed in therefore can't being applicable to.
Summary of the invention
Problem to above-mentioned existing technology existence; The utility model purpose is to provide a kind of flanged (FLGD) high strength steel base Cuprum alloy axle sleeve; Can keep copper layer low coefficient of friction and wear resistance, advantage that thermal conductivity is good, the base steel skin strong with anti-impact force again, that bearing capacity is big has fabulous combination force.
The technological scheme of the utility model is: a kind of flanged (FLGD) high strength steel base Cuprum alloy axle sleeve; Comprise that an end is provided with the base steel skin of flange; Be combined with copper alloy layer with the atom exchange process on the outer field internal surface of said base steel; Said copper alloy layer extends to the end face of whole flange continuously from the outer field internal surface of base steel, and said base steel junction plane outer and copper alloy layer has equally distributed axial groove, and the internal surface of said copper alloy layer is provided with oil groove; Said oil groove is a helix groove, and said oil groove is embedded with solid lubricant.
As preferably, the thickness of said Cuprum alloy is the 0.3-0.5 millimeter.
As preferably, the degree of depth of said groove is the 0.05-0.1 millimeter.
The beneficial effect of the utility model is: use the atom diffusion principle, the atom on the outer junction plane with copper alloy layer of base steel is exchanged fully, thereby formed powerful metallurgical junction and make a concerted effort; The big advantage of the outer anti-impact force of the existing base steel of this axle sleeve; Have copper alloy layer thermal conductivity, strong point that wear resistance is good again, particularly be shaped on oil groove and be embedded with the structure of solid lubricant, make bearing when work; Even under no oil condition; Because solid lubricant forms one deck transfer membrane through frictional heat, thereby has reduced friction factor, phenomenon that unlikely appearance " is stung axle ".

Among the figure: 1, base steel is outer; 2, flange; 3, copper alloy layer; 4, solid lubricant; 5, groove.
Embodiment
As a kind of mode of execution of the utility model, as depicted in figs. 1 and 2, a kind of flanged (FLGD) high strength steel base Cuprum alloy axle sleeve; Comprise that an end is provided with the base steel outer 1 of flange 2; Be combined with copper alloy layer 3 with the atom exchange process on the internal surface of said base steel outer 1, the thickness of said Cuprum alloy is the 0.3-0.5 millimeter, and said copper alloy layer 3 extends to the end face of whole flange 2 continuously from the internal surface of base steel outer 1; The junction plane of said base steel outer 1 and copper alloy layer 3 has equally distributed axial groove 5; The degree of depth of said groove 5 is the 0.05-0.1 millimeter, and the internal surface of said copper alloy layer 3 is provided with oil groove, and said oil groove is a helix groove; Said oil groove is embedded with solid lubricant 4, and said solid lubricant 4 is a graphite.
The utility model is used the atom diffusion principle, and the atom on the junction plane of base steel outer 1 and copper alloy layer 3 is exchanged fully, thereby has formed powerful metallurgical junction and make a concerted effort; The big advantage of outer 1 anti-impact force of the existing base steel of this axle sleeve; Have copper alloy layer 3 thermal conductivity, strong point that wear resistance is good again, particularly be shaped on oil groove and be embedded with the structure of solid lubricant 4, make bearing when work; Even under no oil condition; Because solid lubricant 4 forms one deck transfer membrane through frictional heat, thereby has reduced friction factor, phenomenon that unlikely appearance " is stung axle ".
