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.
CN101451451A, title " timing chain of motor ", comprise the chain sheet being connected into chain and the pin being connected each chain sheet, every section of chain is combined by chain sheet arranged side by side, the chain sheet of each section of adjacent chain is staggered embedding mutually, connect with pin, the inner side of chain sheet is shaped with involute sprocket, chain is embedded in rubber tape, an entirety is made with rubber tape, the flank of tooth of sprocket is equal with the inner side toothed surface of rubber tape, in rubber tape, the outer fix of chain is embedded with tyre cord, and rubber tape material adopts nitrile rubber or fluorine rubber.Its deficiency: working life is short.
Model utility content
Purpose of design: avoid the deficiency in background technique, if one can either substitute belt and gear, have heat-resisting, wear-resisting, anti-oxidant, corrosion-resistant, long service life again, a kind of motor vanadinizing timing chain that motor height rotating speed, variable load, many impacts etc. require can be met again.
Design proposal: in order to realize above-mentioned purpose of design.1, the design of chain hinge pin workpiece surface diffusion metallizing layer is one of technical characteristics of the present utility model.The object of such design is: form metal alloy layer in surface layer metallic atom being infiltrated steel, make bearing pin workpiece surface have the characteristic of some alloyed steel, special steel, as heat-resisting, wear-resisting, anti-oxidant, corrosion-resistant etc.What 2, silent chain adopted is the design of inside and outside compound engaging tooth shape chain, is technical characteristics two of the present utility model.The object of such design is: when the structural type of this New Silent Chain and novel tooth form determine engaging-in with drive sprocket in silent chain transmission process, what first the inside curve flank profil of evagination realized is the internal messing with an one gear teeth, engaging-in further along with these gear teeth, due to relatively rotating between adjacent link, then these gear teeth gradually with the outside profile contact of the work carrier bar of adjacent link, achieve outer gearing, until the outer gearing of work carrier bar is positioned on sprocket indentations, complete an engaging-in process.When being nibbled out by driven sprocket, being but be transitioned into internal messing gradually by outer gearing with engaging of sprocket tooth, thus completing a process of nibbling out.3, Chain-plate Shaped is profile of tooth and profile of tooth engagement cambered surface is the design of shaggy tooth Surface of action, is technical characteristics three of the present utility model.The object of such design is: because concavo-convex Surface of action decreases engagement surface of contact, and the tooth of concavo-convex engaging tooth in concavo-convex Surface of action is along being arcuate structure, contact points is made again to form arc engagement, fundamentally significantly reduce at high-power, high moment of torsion, noise at a high speed, under variable load operating mode, not only achieve the purpose of design of silent chain, and greatly extend the working life of chain.
Technological scheme: a kind of motor vanadinizing timing chain, comprises engine timing chain, the chain hinge pin in described engine timing chain is GCr15 bearing pin and GCr15 bearing pin surface layer is diffusion metallizing layer; Chain-plate Shaped in described engine timing chain is profile of tooth and profile of tooth engagement cambered surface is shaggy tooth Surface of action.
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 transition gradually due to medial and lateral engagement, make the alternately carrying of the inside and outside survey flank profil of chain sheet and bearing pin two side bus, chain sheet pin shaft hole both sides, not only alleviate the wearing and tearing of silent chain chain sheet and bearing pin, and make sprocket teeth alternately carrying, alleviate the wearing and tearing of sprocket teeth; Four or two be fundamentally significantly reduce at high-power, high moment of torsion, noise at a high speed, under variable load operating mode, not only achieve the purpose of design of silent chain, and greatly extend the working life of chain; Five is that bearing pin adopts GCr15 material surface diffusion metallizing enhancement process, tensile strength is generally 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.
