Abstract
The utility model relates to a bushed chain for engine, the chain is formed by the combination of inner link and outer link, inner plate and sleeve formation inner link, outer chain plate and round pin axiform become the outer link, the sleeve passes two inner plates to two outer chain plate departments, the round pin axle passes sleeve and outer chain plate, the sleeve respectively with a round pin axle clearance fit, the sleeve be locating assembly, two oilholes along axial direction point -blank, just two oilholes are about the middle symmetry of sleeve, sleeve internal layout oil duct, the utility model discloses an improve the tube -in -tube structure, add the oilhole on the sleeve, wall cloth office oil duct in the sleeve, sleeve carry out the orientation assembly, have strengthened telescopic lubricating ability, have improved the abrasive resistanc of chain, have strengthened the life -span of chain.
Description
Technical field
The utility model relates to a kind of auto parts machinery, particularly a kind of engine bush(ing) chain.
Background technology
In recent years, due to chain transmission transferring power efficiently, the continuous maturation of high-speed chain drive technology, can reduce simultaneouslyMaintenance cost, therefore chain transmission has been widely used in engine art.
Vehicular engine high speed is high, requires bush(ing) chain to have good greasy property and high-wearing feature, and seamless steel tube lubricating conditionPoor, the sleeve with an oilhole in prior art is lubricated not good, and in order to improve lubricity, oilhole size is larger, and sleeve is resistance toMill property weakens.
Summary of the invention
What the utility model solved is the lubricated insufficient and not wear-resisting technical problem of bush(ing) chain, improves the profit between sleeve and bearing pinSliding ability, has increased sleeve store oil function, has improved the abrasive resistance of chain, the life-span that has strengthened chain.
The technical solution of the utility model is:
A kind of engine bush(ing) chain, chain is combined by inner link and outer link, and inner plate and sleeve form inner link, outerCarrier bar and bearing pin form outer link, and sleeve is through two inner plate to two outer plate places, and bearing pin is through sleeve and outer plate, its featureBe: sleeve has upper and lower two oilholes, sleeve inner is arranged oil duct.
Preferably: sleeve and bearing pin are matched in clearance.
A kind of bush(ing) chain as claimed in claim 1, is characterized in that: two oilholes of sleeve along sleeve axial direction at oneOn straight line, and two oilholes are about sleeve centre position symmetry.
Preferably: sleeve orientation assembling, oilhole is positioned at the offside of bearing pin and sleeve contact-making surface.
Preferably: oil duct is curve, annular or zigzag structure.
Compared with prior art, the utility model, in order to improve the deficiency of above-mentioned bush(ing) chain, arranges two oilholes on sleeve, andIn axial direction point-blank, two oilholes, about sleeve centre position symmetry, are conveniently realized assembled orientation, simultaneously sizeLess than single oilhole, can meet the greasy property of chain, can ensure again the requirement of strength of sleeve. Meanwhile, in order to improve sleeveWith the anti-wear performance of bearing pin, ensure the requirement to the wear-resisting percentage elongation of chain, at sleeve disposed inboard oil duct, version is various,Can be curve, can be annular, can be zigzag.
The utility model, by improving tube-in-tube structure, adds oilhole on sleeve, and at sleeve lining layout oil duct, sleeve is determinedTo assembling, strengthen the lubricating ability of sleeve, improve the abrasive resistance of chain, strengthen the life-span of chain.

Detailed description of the invention
A kind of engine bush(ing) chain, chain is combined by inner link and outer link, and inner plate 2 forms inner link with sleeve 4,Outer plate 1 forms outer link with bearing pin 3, and sleeve 4 is through two inner plate 2 to two outer plate 1 places, and bearing pin 3 is through sleeve 4With outer plate 1, sleeve 4 and bearing pin 3 matched in clearance, sleeve 4 has 5 and 6, two oilholes of upper and lower two oilholes side verticallyTo point-blank, oilhole 5 and 6 is about cover simple centre position symmetry, and oilhole is positioned at the offside of bearing pin and sleeve contact-making surface,Be convenient to assembled orientation, have two fuel feed holes, the oil inlet quantity of sleeve increases, fully lubricated, improves the anti-wear performance of chain, coverCylinder inwall is arranged oil duct, and sleeve inner arranges that the structure of oil duct can be curve 7, can be annular 8, can be zigzag 9,Oil duct can play good store oil effect, forms certain thickness oil pressure film at bearing pin and sleeve contact area, has avoided bearing pinWith the direct contact friction of sleeve, improve the abrasive resistance of chain, the life-span that has strengthened chain.
Claims (5)
1. an engine bush(ing) chain, chain is combined by inner link and outer link, and inner plate and sleeve form inner link,Outer plate and bearing pin form outer link, and sleeve is through two inner plate to two outer plate places, and bearing pin is through sleeve and outer plate, its spyLevy and be: sleeve has upper and lower two oilholes, sleeve inner is arranged oil duct.
2. a kind of engine bush(ing) chain as claimed in claim 1, is characterized in that: sleeve and bearing pin are matched in clearance.
