Description
Technical field
The present invention relates to a kind of chain, more particularly to a kind of dust-proof chain.
Background technology
Cement chain is generally used for conveying ore, coal, the material such as cement medium, cement chain working environment not only with
Strong impact and with substantial amounts of dust, working environment is very severe.Because work material and a large amount of dust easily immerse chain
In the hunting link of bar, cause to fill substantial amounts of exotic between chain hinge pin and sleeve in original running clearance, cause to turn
Dynamic gap shrinks, the resistance increase relatively rotated between bearing pin and sleeve, so as to increase the abrasion between bearing pin and sleeve, when
When filler reaches a certain amount of, the stuck of chain is may result in, make chain that kaka sound is sent when running and finally result in chain breakage
Failure.In order to prevent dust from entering in sleeve, we devise a kind of dust-proof chain with ring structure.
Can effectively prevent dust from entering sleeve using dust-proof chain disclosed by the invention, effectively improve dust
Aggravate the abrasion between bearing pin and sleeve after into guide, substantially increase the service life of chain.
The content of the invention
It is existing to solve it is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of dust-proof chain
Chain in technology, is especially applied in the adverse circumstances containing a large amount of dust, and dust is easily accessible in chain barrel
So as to cause the technical problem that chain anti-wear performance is poor, service life is short.
The present invention is achieved by the following technical solutions：It is by including the invention discloses a kind of dust-proof chain
The loop configuration of multiple chain link head and the tail connection compositions, chain link includes the outer curved attached plate of macropore, aperture outer curved attached plate, inner link, bearing pin
Only lock pin, the outer curved attached plate of macropore and the outer curved attached plate of aperture are respectively positioned at the both sides of inner link, curved attached plate and interior chain outside large and small hole
Section is connected by bearing pin, and the bottom of bearing pin is provided with lockhole, and the axis of lockhole intersects and vertical with the axis of bearing pin, only lock pin insertion
Lockhole；Inner link is fixed with two sleeves by two pieces of inner plates being oppositely arranged and constituted, and two are respectively provided with every piece of inner plate
Bore, sleeve is inserted in the bore being oppositely arranged respectively, and chain link also includes sealing ring, and the both ends of the surface of sleeve exceed in two pieces respectively
Plane where carrier bar outside, the two ends of sleeve are cased with sealing ring respectively；Can be by sleeve and the outer curved attached plate of macropore by sealing ring
And the outer curved attached plate of aperture is sealed, and prevents dust from entering the endoporus of sleeve.
Further, annular deep gouge, the axle of deep gouge are additionally provided with order to sealing ring is fixed, on the outside of inner plate
Line overlaps with the axis of sleeve, and the diameter of deep gouge is equal in magnitude with the external diameter of sealing ring, and during installation, the bottom of sealing ring is arranged on
In deep gouge, top and the inner side of curved attached plate outside macropore or the interior side contacts of the outer curved attached plate of aperture of sealing ring, this makes it possible to say
Sealing ring is fixed installation.
Further, in order to improve sealing effectiveness, more preferable robust seal circle, the outer curved attached plate of macropore and the outer curved attached plate of aperture
Inner side be respectively provided with two v-depressions of annular shape, the top of sealing ring is located in v-depression, when fixed, the axle of sleeve
The ring heart of the annulus that line is formed through v-depression, prevents sealing ring installation deviation from causing sealing not good.
Further, in order to increase the elasticity of sealing ring and improve service life, the material that sealing ring is selected is fine for fourth
Rubber.
Further, sealing ring is installed for convenience, there is provided installing space and raising sealing, the two ends of sleeve
Length of the face respectively beyond plane where two pieces of inner plate outsides is identical, and the end face of sleeve is beyond plane where inner plate outside
Length is the 1/2~3/4 of sealing ring thickness.
Further, in order to preferably prevent dust from entering the gap of bearing pin and outer curved attached plate, the outer curved attached plate of macropore and small
Curved attached plate is L-shaped outside hole.
Can effectively prevent dust from entering sleeve the invention discloses a kind of dust-proof chain, be made using nitrile rubber
It is sealing ring material, it has Wear-resistant, high-temperature resistant and rich very strong elasticity, this elasticity is solved because carrier bar thickness of slab is missed very well
Difference causes the problem that sealing ring can not be compacted completely.Inner link middle sleeve assembling protrusion inner plate certain altitude is (to appear
Amount), height of appearing is generally higher than the half thickness of sealing ring one, can effective fixed seal ring, curved attached plate design V-type outside large and small hole
Slot structure, can effectively compress sealing ring, and inner plate is designed with deep gouge, can effective fixed seal ring outer ring movement track；The present invention
Effectively improve dust and enter the abrasion aggravated between bearing pin and sleeve after guide, substantially increase the service life of chain.
