Abstract
The utility model relates to one and has heat-resisting, wear-resisting, anti-oxidant, corrosion resistant vanadinizing 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 layer, 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 vanadinizing 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 vanadinizing chain hinge pin.
Design proposal: in order to realize above-mentioned purpose of design.The design of chain hinge pin workpiece surface diffusion metallizing layer is technical characteristics of the present utility model.The object of such design is: infiltrated by metallic atom in the surface layer of steel, it can be make the surface of bearing pin form alloy-layer, bearing pin workpiece surface is made to have the characteristic of some alloyed steel, special steel, as heat-resisting, wear-resisting, anti-oxidant, corrosion-resistant etc., thus drastically increase heat-resisting, wear-resisting, anti-oxidant, the corrosion resistance of bearing pin.
Technological scheme: a kind of vanadinizing chain hinge pin, chain hinge pin is GCr15 bearing pin and GCr15 bearing pin surface layer is diffusion metallizing layer.
The utility model is compared with background technique, and one is the design adopting GCr15 material to make bearing pin and diffusion metallizing layer, makes chain hinge pin have heat-resisting, wear-resisting, anti-oxidant, the corrosion-resistant several times that obtain and improves, the working life of bearing pin 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 design of bearing pin metallic cementation layer, bearing pin tensile strength is made to reach 6.0-7.0kN, 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 vanadinizing 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 Vanadized layer, and this Vanadized layer has highly reliable heat-resisting, wear-resisting, anti-oxidant, rotproofness, can adapt to different surrounding mediums respectively, 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.
