Abstract
The utility model relates to one can meet high-power, high moment of torsion, again can under the operating mode of high speed, variable load, realize long lifetime, motorcycle engine timing system drive chain that noise is little, its comprises the guide plate of inside and outside staggered mutual embedding one-tenth chain, carrier bar and bearing pin, and described Chain-plate Shaped is profile of tooth and profile of tooth engagement cambered surface is shaggy tooth Surface of action.Advantage: one is be specially adapted at a high speed and the operating mode of speed change, variable load, reduces polygon effect, reduces shock and vibration, reduces noise, improves transmission efficiency.Simultaneously, due to the transition gradually of 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; Two is fundamentally significantly reduce noise, not only achieves the purpose of design of silent chain, and greatly extends the working life of chain.
Description
Technical field
The utility model relates to one can meet high-power, high moment of torsion, again can at a high speed, under the operating mode of variable load, realize long lifetime, motorcycle engine timing system drive chain that noise is little, belong to motorcycle engine special chain drive and manufacture field.
Background technique
CN101101049A, title " high speed transmission toothed chain and sprocket ", comprise silent chain chain and sprocket wheel, it is characterized in that the interior outside of two-sided engagement carrier bar wide all with the gear teeth meshing of sprocket wheel, when silent chain chain and the sprocket engagement of two-sided engagement, inside carrier bar, first flank profil engages with sprocket teeth, with the rotation of sprocket wheel, to be progressively transitioned into inside carrier bar flank profil and outside flank profil simultaneously and sprocket engagement, until outside flank profil is positioned on the gear teeth of sprocket wheel.Its deficiency: this high speed transmission toothed chain and sprocket due to the design of chain board size unreasonable, cause at high-power, high moment of torsion, at a high speed, under the operating mode of variable load, its noise be large.
Model utility content
Purpose of design: avoid the deficiency in background technique, if one can meet high-power, high moment of torsion, again can at a high speed, under the operating mode of variable load, realize long lifetime, motorcycle engine timing system drive chain that noise is little.
Design proposal: in order to realize above-mentioned purpose of design.What 1, silent chain adopted is the design of inside and outside compound engaging tooth shape chain, is one of technical characteristics 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.2, 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 two 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 motorcycle engine timing system drive chain, its comprises the guide plate of inside and outside staggered mutual embedding one-tenth chain, carrier bar and bearing pin, and described Chain-plate Shaped 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 be specially adapted at a high speed and the operating mode of speed change, variable load, reduces polygon effect, reduces shock and vibration, reduces noise, improves transmission efficiency.Simultaneously, due to the transition gradually of 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; 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.

Embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of motorcycle engine timing system drive chain, its comprises the guide plate 3 of inside and outside staggered mutual embedding one-tenth chain, carrier bar 1 and bearing pin 2, and described carrier bar 1 shape is profile of tooth and profile of tooth engagement cambered surface is shaggy tooth Surface of action 4.Tooth-shape angle in carrier bar 1 is 60 °.Carrier bar is provided with two chain pin axis holes and chain plate hole heart distance is 6.27-6.29mm.Carrier bar width is 11.94-12mm, and Link plate height is 6.66-6.70mm, and thickness of link plates is 1-1.03mm, and roughness is Ra1.6.Described carrier bar heat treatment hardness is 50-54HRC.Motorcycle engine timing system drive chain formula: 1. the hole heart is apart from a=p-Δ, p-Δ represents that the chain plate hole heart is apart from deducting carrier bar and bearing pin gap, and 2. apothem f=0.40p, p represent chain plate hole heart distance, and 3. standard pitch diameter is 68.82mm, and 4. modulus is 2.021.
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.
