Description
Technical field
The utility model relates to a kind of power transmission sleeve roller chain, especially a kind of dust seal chain.
Background technique
It is solid that sleeve roller chain by inner plate, outer plate, sleeve, pin shaft, roller forms single-row or multiple row structure, pin shaft
It is scheduled on outer plate, sleeve is fixed on inner plate, is respectively formed between sleeve and pin shaft between roller and sleeve coaxial rotatable
Connection structure, chain is mainly rolling friction with engaging for sprocket wheel, thus bushroller chain is light-weight, the service life is long, at low cost,
It is widely used in power transmission, such as existing motorcycle and bicycle are usually all using the chain of single-row bushroller chain and chain crop rotation
For power transmission members.Chaindriven failure mode mainly has carrier bar fatigue rupture；The impact fatigue of roller, sleeve is destroyed, is sold
The gluing of axis and sleeve, chain hinge pin abrasion, overload are broken.Since chaindriven meshing impact is held by roller and sleeve first
By.Under repeated multiple times impact, by certain cycle-index, impact fatigue destruction may occur for roller, sleeve.And it wears
It is mechanically operated inevitable phenomenon, however the gap generated after being worn between roller and sleeve and sleeve and pin shaft, it exacerbates
Impact influences, and apparent noise occurs；And the consequence impacted also results in abrasion aggravation.Especially in exposed drive, use
When harsh environmental conditions and insufficient lubrication, chain link is elongated after chain abrasion, is also easy to cause to jump tooth or de- chain, thus sharply
Reduce the service life of chain.The chain conveyer of existing motorcycle belongs to typical exposed drive, and use environment inclement condition, profit
The sliding grease only injected before chain factory is supported, after long-time use, lubrication exists serious bad.To ensure that chain has reason
The lubricant effect thought has had already appeared a kind of sealed chain using 0 type sealing ring, by the inside of roller end face and inner plate
Between face, alternatively, 0 type sealing ring is arranged, between inner plate and outer plate simultaneously to form end face seal.It is this to use 0 type
The sealing structure that circle forms end face seal is mainly used for static seal, and there are the resistances of motion to occur greatly and easily for dynamic sealing
Sealing ring early damage phenomenon.However, between roller and inner plate, alternatively, belonging to the structure of relative motion between interior outer plate
Part.Therefore, this chain in actual use, early period service stage, transmission efficiency was low, and it is old the abrasion of 0 type circle then occur
There is the defect of the rupture of 0 type circle, significant sealing affection decline after reusing a period of time in the slag-off phenomenon of change.For this reason, it may be necessary into
One step is improved.
Summary of the invention
The purpose of the present invention is to the low deficiencies of existing bushroller chain sealing structure service life, provide a kind of anti-
Dirt sealed chain, the chain is by being arranged gasket at least one side of inner plate, with effective seal sleeve and roller
Between, and/or, the lubricant grease between sleeve and pin shaft to effectively prolong the service life, and can reduce noise.And structure
Simply, the assembling work of chain production is convenient, and manufacturing cost is low.
To realize foregoing purpose, the utility model adopts the following technical solution.
A kind of dust seal chain, including inner plate, outer plate, sleeve, pin shaft and roller, in the inside of the inner plate
And/or outside is equipped with gasket seal, which is equipped with corresponding two perforation across the sleeve or pin shaft.
Using the utility model of preceding solution, due to being equipped with gasket at least one side of inner plate
Piece is made between inner plate and roller end face using the sealing characteristics of gasket, and/or, the interior outer plate of sleeve end face periphery it
Between formation sealing structure, between effective seal sleeve and roller, and/or, the lubricant grease between sleeve and pin shaft extends
Service life, and noise can be reduced.Obviously, in the technical solution of the equal gasket seal in inner plate two sides, between sleeve and roller,
And sealing structure has been respectively formed between sleeve and pin shaft, the lubricant grease both having can effectively protect therebetween is non-leakage, it is ensured that lubrication
Effect can also effectively prevent the intrusion of the solid impurities such as dust, silt wherein, by preventing wear medium from invading, keep good
Relative motion environment.In addition, the roller that can effectively prevent is disengaged with the sprocket of sprocket wheel since gasket seal leans against roller end face
Inertia rotation afterwards, from the fretting wear reduced between roller and sleeve on the other hand.And structure is simple, production item assembly
Increase the operation for placing gasket seal, a small amount of increased costs in the process.
Preferably, the peripheral profile of the gasket seal is identical as the peripheral profile of the inner plate.To keep and tradition
Bushroller chain no significant difference in shape, forms the protection to gasket using carrier bar.
Preferably, the gasket seal with a thickness of 0.50~1.50mm.The spacer thickness is poor because of material difference
It is different, suitable relatively thin, the higher material of hardness such as plastics, reinforced plastics, nylon for rubber type of material lower for hardness
Or non-ferrous metal etc. is preferably relatively thick is preferred, and both to have enough sealings and vibration absorbing performance, and is able to maintain longer life.Work as material
When material is using plastics or reinforced plastics, thickness is best with the 0.80mm 0.10mm that floats up and down.
Preferably, the gasket seal is formed by rubber, plastic layer or nylon injection-molding.To utilize maturation in the prior art
Process and technological means, it is ensured that product quality improves production efficiency, reduces manufacturing cost.
Preferably, the gasket seal is punched by non-ferrous metal forms.To utilize process mature in the prior art
And technological means, it is ensured that product quality improves production efficiency, reduces manufacturing cost.Wherein, coloured technology includes brass, red copper
Deng.
Experiments verify that the utility model is compared with using the sealed chain of 0 shape sealing ring, service life can be improved 20%
Left and right, noise can reduce by 3~5 decibels, and comprehensive production cost can reduce by 10% or so.In the actual observation hair to operational process
Existing, moment pauses after roller disengages sprocket wheel, noninertia rotation.
The utility model has the beneficial effects that being located at the gasket seal of inner plate side, sealing function is both played, is also had
Vibration-absorbing denoising effect, long service life, noise are small, use cost is low.
