Description
Technical field
A kind of auto parts machinery is the utility model is related to, more particularly to a kind of automobile engine bush(ing) chain.
Background technology
At present, Chain conveyer has been widely used for car engine timing by advantages such as its high reliability, low costs
In the systems such as chain, oil pump chain, but fatigue behaviour, anti-wear performance are still the two big technological difficulties for restricting industry development.
Chain subjects from alternate load effect caused by pilled-in selvedge and slack list repeatedly in actual moving process, along with
Carrier bar and firmness caused by bearing pin, sleeve interference fit（Extrusion pressure）Decay, occur between the part of interference fit relative
Loosen, produce Relative friction so that carrier bar endoporus region of stress concentration is cracked, ultimately results in chain fatigue fracture.Chain
Anti-wear performance is then embodied on elongation, in high engine speeds operating, due to the reason such as fuel feeding deficiency between sleeve, bearing pin, is made
Sharp wear is produced into both, bearing pin is produced flexural deformation by the effect of tension, causes chain to be failed because of overlength.
Traditional automobile using bushed chain, processing of not appeared between sleeve and inner plate, the fillet of sleeve end face and footpath
Contracting has seriously undermined the firmness of inner link, and supply capability is poor between sleeve, bearing pin, and abrasion is more serious.
The content of the invention
In view of the shortcomings of the prior art, the utility model proposes a kind of belt for scraper chain oil duct sleeve chain structure, solves sleeve
Extrusion pressure deficiency between carrier bar, the insufficient technical problem of chain greasisng, it is antifatigue, wear-resisting fundamentally to enhance chain
Performance.
The technical solution of the utility model is：A kind of automobile engine bush(ing) chain, including inner plate are matched somebody with somebody with sleeve interference
Close inner link, outer plate and the bearing pin formed and be interference fitted the outer single-unit to be formed, wherein bearing pin passes through sleeve, and forms gap and match somebody with somebody
Close, realize that inner link, outer link are interlaced and mutually embedding be combined into whole chain；In the inner link structure, sleeve passes through inner plate, and
The amount of appearing is the 1.5%-4% of sleeve outer diameter.
Outer plate disposed inboard lubricating oil oil guide groove, oil groove avoid region of stress concentration on the inside of chain plate hole.
Lubricating oil oil guide groove type is trapezoidal, arc or V-type, oil groove starting point（Inner port edge）Groove width increase gradual change extremely
Terminal groove width.
Lubricating oil oil guide groove path is wall scroll or a plurality of linear pattern, shaped form structure, and on carrier bar transverse direction, longitudinal center
Line is symmetrical.
Technical characteristics of the present utility model and effect are：Chain strip adoption sleeve is appeared processing, and the amount of appearing is outside sleeve
The 1.5%-4% in footpath, inner link extrusion pressure is increased 40%-60%, effectively prevent the relative slip between two parts of interference fit,
Improve chain anti-fatigue ability.In addition, in order to solve the insufficient problem of chain greasisng, led in outer plate disposed inboard lubricating oil
Oil groove, while effectively mitigating inner link axial float, the lubricity between sleeve diameter and bearing pin is improved, is effectively reduced set
Abrasion between cylinder and bearing pin, the performance of chain is improved on the whole.

Embodiment
The utility model is described in further detail for explanation and embodiment below in conjunction with the accompanying drawings：
A kind of automobile engine bush(ing) chain, including inner link, the outer plate 1 that inner plate 2 is formed with the interference fit of sleeve 4
The outer single-unit formed with the interference fit of bearing pin 3, wherein bearing pin 3 pass through sleeve 4, and form gap cooperation, realize inner link, exterior chain
Save and interlaced mutually embedding be combined into whole chain.Inner link middle sleeve passes through inner plate, and the amount of appearing is equal to the 1.5%- of sleeve outer diameter
4%, the conventional structure of inner link 5 is converted to interior single-unit structure 6 after improving, on the inside of outer plate lubricating oil oil guide groove path 7 be wall scroll or
A plurality of linear pattern, shaped form oil guide groove, and it is symmetrical on carrier bar transverse direction, longitudinal centre line.Sump type be trapezoidal 8, arc 9 or
Person's V-type 10, oil groove starting point（Inner port edge）Groove width 11 increase gradual change groove width 12 to terminal.
Embodiment 1
Current pitch is 9.525mm, and sleeve internal-and external diameter is respectively that 4.51mm, 6.35mm automobile bush(ing) chain carry out experiment and tested
Card, the sleeve amount of appearing are set as 0.12mm, and outer plate disposed inboard path is the lubricating oil oil guide groove of straight line, and sump type is chosen
It is trapezoidal.
It in dynamic loading be 1.64KN to improve front and rear by chain, and in the presence of dead load is 2.0KN, progress 5 times is tired respectively
Labor verification experimental verification, conventional sleeve chain do not pass through 3 × 106Secondary fatigue and cyclic, wherein inner plate fracture failure 4 times.After improvement
Bush(ing) chain passes through 4 × 106Do not occur carrier bar fatigue failure phenomenon yet.
It is steamboat Z1=19 in experimental condition, bull wheel Z2=38, oil jet lubrication, small 3800 revs/min of wheel speed, unilateral of chain
Verified under conditions of power 750N, power 8.64KW by 300h comprehensive performance tests.Chain elongation rate is 0.311% before improvement, is changed
Chain elongation rate of dealing with problems arising from an accident is 0.037%, effectively increases chain anti-wear performance.
