Abstract
The utility model relates to one and has heat-resisting, wear-resisting, anti-oxidant, corrosion resistant a kind of aluminising chain hinge pin, and chain hinge pin is GCr15 bearing pin and GCr15 bearing pin surface layer is diffusion metallizing layer.Advantage: adopt GCr15 material to make the design of bearing pin and diffusion metallizing, make chain hinge pin have heat-resisting, wear-resisting, anti-oxidant, the corrosion-resistant several times that obtain and improve, working life is multiplied.
Description
Technical field
The utility model relates to one and has heat-resisting, wear-resisting, anti-oxidant, corrosion resistant aluminising chain hinge pin, belongs to chain hinge pin and manufactures field.
Background technique
CN101644308A, title " a kind of chain hinge pin and manufacture method thereof ", successively through cutting print, punching, cut-out, 2/4 take all of, 3/4 take all of, 4/4 take all of and full circle processing, and the jointed chain hinge pin of band obtaining rolling after enhancement process, surface finishing and cleaning, this bearing pin is hollow structure, and seam crossing has at least one oil permeable hole.Its deficiency: heat-resisting, wear-resisting, anti-oxidant, corrosion-resistant.
Model utility content
Purpose of design: avoid the deficiency in background technique, if one has heat-resisting, wear-resisting, anti-oxidant, corrosion resistant aluminising chain hinge pin.
Design proposal: in order to realize above-mentioned purpose of design.Chain hinge pin workpiece surface adopts the technological design of diffusion metallizing thermo-chemical treatment, is technical characteristics of the present utility model.The object of such design is: infiltrated by metallic atom in the surface layer of steel, and it can be the surface layer alloyage making bearing pin, makes bearing pin workpiece surface have the characteristic of some alloyed steel, special steel, as heat-resisting, wear-resisting, anti-oxidant, corrosion-resistant etc.The utility model adopts aluminising to carry out chemical heat treatment process in chain hinge pin manufacture process, aluminum metal atom is made to infiltrate in bearing pin metal workpiece top layer, be placed on containing infiltrating in the penetration enhancer of aluminum metal element by bearing pin, be heated to uniform temperature, after keeping appropriate time, the active atomic of the infiltration metallic element that penetration enhancer thermolysis produces just is adsorbed to bearing pin workpiece surface, and diffuses into bearing pin workpiece surface, thus changes chemical composition, the structure and properties of bearing pin workpiece surface.
Technological scheme: a kind of aluminising chain hinge pin, chain hinge pin is GCr15 bearing pin and GCr15 bearing pin surface layer is diffusion metallizing layer.
The utility model, compared with background technique, adopts GCr15 material to make the design of bearing pin and diffusion metallizing, and make chain hinge pin have heat-resisting, wear-resisting, anti-oxidant, the corrosion-resistant several times that obtain and improve, working life is multiplied; Two is the shear strengths strengthening bearing pin; By gear piece aperture extruding resiliently deformable, improve aperture fatigue strength, reduce the wearing and tearing in bearing pin and gear piece aperture, improve whole chain working life and static strength; Three is the designs of bearing pin metallic cementation, makes tensile strength reach 6.0-7.0KN, and can meet the demand of high speed variable load many impacts motor, gear piece aperture extruding resiliently deformable completely, the friction pair formed with bearing pin improves fatigue strength, improves polishing machine.
Accompanying drawing explanation
Fig. 1 is the end-face structure schematic diagram of chain hinge pin.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of aluminising chain hinge pin, chain hinge pin is GCr15 bearing pin 1 and GCr15 bearing pin surface layer is diffusion metallizing layer 2.Described bearing pin tensile strength is 6.0-7.0KN.
Embodiment 2: on the basis of embodiment 1, and described diffusion metallizing layer 2 is aluminized coating, and this aluminized coating has highly reliable heat-resisting, wear-resisting, anti-oxidant, rotproofness, makes obtain the raising of several times the working life of chain hinge pin.
It is to be understood that: although above-described embodiment to be contrasted detailed text description to mentality of designing of the present utility model; but these text descriptions; just the simple text of the utility model mentality of designing is described; instead of the restriction to the utility model mentality of designing; any do not exceed the utility model mentality of designing combination, increase or amendment, all fall in protection domain of the present utility model.
