Abstract
The present invention provides a kind of small displacement lightweight oil seal chain, is formed with outer single-unit, interior single-unit and sealing ring, and sealing ring is located between inside and outside single-unit contact surface；Interior single-unit is made up of sleeve, inner plate, set of rollers assembling conjunction；Outer single-unit is made up of the bearing pin being set in sleeve with outer plate using interference fit, and outer plate is provided with lightening hole；Sealing ring is shaped as lip type.The technical program improves the tensile strength of chain, fatigue strength, extends chain service life, and with excellent reliability.
Description
Technical field
The present invention relates to a kind of chain, more particularly to a kind of small displacement lightweight oil seal chain.
Background technology
With the development growth in the living standard of society, small displacement (150CC) following vehicle is gradually developed cross-country contour
Vehicle is held, mill run can not meet the performance requirement of first kind locomotive.
The content of the invention
In order to break through this present situation, oiling chain is exempted from it is an object of the invention to provide a kind of suitable below 150CC locomotives
Bar.
Technical scheme is as follows：
A kind of small displacement lightweight oil seal chain, is formed with outer single-unit, interior single-unit and sealing ring, and sealing ring is located inside and outside
Between single-unit contact surface；Interior single-unit is made up of sleeve, inner plate, set of rollers assembling conjunction；Outer single-unit is by the pin that is set in sleeve
Axle is constituted with outer plate using interference fit；Sealing ring is shaped as lip type, and the section of lip type is the semi arch and X of common O-ring
The Half-edge Structure of type circle.The technical program injects special lubricant grease in sleeve, is sealed up for safekeeping in the presence of special seal circle
In sleeve, lubricant grease reduces bearing pin and sleeve friction, reduction in sleeve and pin slide contact surface formation current lubrication oil film
Localized hyperthermia of the chain under the state of running at high speed, so as to reduce the abrasion of chain, therefore chain operationally can be in order to avoid refuel.
Sealing ring is under the effect of inside and outside single-unit pressure, and firmly patch and inside and outside single-unit contact surface, prevent the entrance of foreign, press down simultaneously
During high-speed cruising processed junction grease overflow, it is ensured that hinged place fully and long-acting lubrication.
Using lip-shaped sealed ring (such as Fig. 3), sealing ring is deformed upon under the effect of interior outer plate, and reference view 4 is realized
The oil sealing of chain.Contact area after lip type cast becomes is smaller than common O-ring by 50%, increases than common O-ring pocketed oil groove, together
Etc. under abrasive conditions, anti-wear performance improves 50% than common O-ring.
To ensure that interior outer plate and sealing ring keep enough contacts area, outer plate, inner plate are used with piece shape, wide waist
Structure, interior outer plate is equipped with lightening hole to mitigate weight, be easy to lubricate, be easy to blowdown mud triple role.The bearing pin is used
Large scale superior alloy steel, which makes, has high-end tension and fatigue strength, and bearing pin two ends are used after being each passed through sleeve and outer plate
Cubic die is locked.Whole piece chain strip adoption vacuum oiling method, it is ensured that lubricant grease is sufficiently injected in every pitch chain bar, chain
Run after assembling using potent prestretching and technique is in 60% Breaking load pretension and holding acts on 30s on chain, it is ensured that chain
Intensity and fatigue behaviour.The technical program improves the tensile strength of chain, fatigue strength, extends chain service life,
And with excellent reliability.
Preferably：Sealing ring material is nitrile rubber or hydrogenated butyronitrile glue.

Embodiment
A kind of small displacement lightweight oil seal chain, is formed with outer single-unit, interior single-unit and sealing ring 6, and sealing ring 6 is located at interior
Between outer single-unit contact surface；Interior single-unit from sleeve 4, inner plate 1, roller 3 assemble with constitute；Outer single-unit is by being set in sleeve 4
Interior bearing pin 5 is constituted with outer plate 2 using interference fit；Sealing ring 6 is shaped as lip type:Outer plate 2, inner plate 1 use same piece
Shape, wide waist structure, interior outer plate are all provided with lightening hole 7 to mitigate weight chain.Bearing pin 5 is made using large scale superior alloy steel.
The two ends of bearing pin 5 are passed through after sleeve 4 and outer plate 2, are locked using cubic die.The material of sealing ring 6 is nitrile rubber or hydrogen
Change NBR.This chain has high tensile strength, fatigue strength, wearability.The motor automobile oil being made of such scheme
Chain is sealed, tensile strength can reach 24kN, and fatigue strength circulates 5,000,000 times, anti-wear performance≤0.3% under 23% load.
