Abstract
The utility model relates to one and can either substitute Timing Belt and gear, have long service life, meet again the novel inside and outside compound engaging tooth shape chain that motor car engine requires, noise is low, the carrier bar two between cog flank profil inside and outside described in compound engaging tooth shape chain is evagination circular arc flank profil, outside flank profil is straight-side profile.Advantage: one is due to the compatible internal messing of inside and outside compound engaging tooth shape chain, outer gearing, particularly suitable at a high speed and the operating mode of variable load, speed change, reduces polygon effect, reduces shock and vibration, reduce noise, improve transmission efficiency; Two is because interior outer gearing hockets, and makes outside flank profil, bearing pin two side bus, chain-plate pin axis hole alternately carrying in carrier bar, alleviates the wearing and tearing of carrier bar and bearing pin, and also alleviate the wearing and tearing of involute sprocket wheel.
Description
Technical field
The utility model relates to one and can either substitute Timing Belt and gear, have long service life, meets again the timing transmission chain that motor car engine requires, noise is low, belongs to automobile chain and manufactures field.
Background technique
Publication number CN101451451A, title " timing chain of motor ", comprise the carrier bar being connected into chain and the bearing pin being connected each carrier bar, 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, with pinned connection, 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, noise is large.
Model utility content
ifmeter object: avoid the deficiency in background technique, design one can either substitute belt and gear, has again long service life, automotive gasoline engine Tooth Profile chain that noise is little.
Design proposal: in order to realize above-mentioned purpose of design.On the basis of the timing chain of available engine, achieved long lifetime and the low noise of automotive gasoline engine Tooth Profile chain by the further improvement of the profile of tooth to its carrier bar.In structural design, the inner plate profile geometry of inside and outside compound engaging tooth shape chain is inner side flank profil is evagination circular arc flank profil, outside flank profil is straight-side profile, the circular flank profil of evagination is meshed with the sprocket tooth form that the work circular arc between straight-side profile engages with it, chain hinge pin is through stretching out guide plate two ends, as shown in Figure 1, when carrier bar profile of tooth engages with drive sprocket, first the inner side flank profil of evagination realizes the internal messing of gear teeth, along with further engagement, due to relatively rotating of adjacent link, these gear teeth again with the outside profile contact of adjacent link, realize outer gearing, then complete an engagement process, just the opposite when engaging with driven sprocket, the compatible internal messing of inside and outside compound engaging tooth shape chain, the feature of outer gearing, particularly suitable at a high speed and variable load, the operating mode of speed change, reduce polygon effect, reduce to impact, vibration, reduce noise, improve transmission efficiency, because interior outer gearing hockets, make outside flank profil in carrier bar, bearing pin two side bus, chain-plate pin axis hole is carrying alternately, alleviate the wearing and tearing of carrier bar and bearing pin, and the wearing and tearing of involute sprocket wheel are also alleviated.
Technological scheme: a kind of novel inside and outside compound engaging tooth shape chain, the carrier bar two between cog flank profil in described inside and outside compound engaging tooth shape chain is evagination circular arc flank profil, outside flank profil is straight-side profile.
The utility model is compared with background technique, and one is due to the compatible internal messing of inside and outside compound engaging tooth shape chain, outer gearing, and particularly suitable at a high speed and the operating mode of variable load, speed change, reduce polygon effect, reduce shock and vibration, reduce noise, improve transmission efficiency; Two is because interior outer gearing hockets, make outside flank profil, bearing pin two side bus, chain-plate pin axis hole alternately carrying in carrier bar, alleviate the wearing and tearing of carrier bar and bearing pin, and the wearing and tearing of involute sprocket wheel also alleviated, three be that compact structure, transmitted power are high, reliability and wear resistance high; Four is durable in use, non-maintaining throughout one's life, thus the outer meshing silent chain bar reduced because ignoring periodic replacement serious wear and the chain that causes shift to an earlier date the generation of phenomenon of rupture.
