Abstract
The utility model discloses a kind of dust-proof wear-resisting chain, including several sleeves, inner plate, bearing pin, outer plate and roller, bearing pin is inserted with the sleeve, the bush outer sleeve is provided with roller, connected by the inner plate between the sleeve, the bearing pin two ends are arranged with outer plate, and the sleeve includes sleeve piece, and the sleeve piece is trapezoidal.The utility model provides a kind of dust-proof wear-resisting chain, and the chain has the advantages that simple structure, reasonable in design, dust-proof, wear-resisting, antiseep, long service life.
Description
Technical field
The utility model belongs to chain technical field, and in particular to a kind of dust-proof wear-resisting chain.
Background technology
Traditional bushed chain generally comprises sleeve, bearing pin, inner plate and outer plate, and roller chain also has roller, one
As situation lower bearing pin overcoat be provided with sleeve, between sleeve and sleeve by inner plate connect, bearing pin two ends outside set outer plate,
Due to its structures shape, it has a following obvious shortcoming：1. lubricant grease is highly prone to the pollution of rainwater and dust, especially
It is the exposed use occasion outside of chain, such as motorcycle chain or the severe driving chain of use condition, lubricating oil
Fat goes bad quickly, loses lubricating and antirust performance；Other grease is easily got rid of in high-speed cruising from the gap of interior outer plate, chain
Bar loses greasy property, and the later stage uses to be needed periodically to add lubricating oil, and can only add the machine oil of mobility, the bad profit of mobility
Lubricating oil cannot be added in chain gap, do not have a lubrication, and the oil of mobility be doomed to be easy in running at high speed by
Get rid of away；2. the silt in the external world is easily accessible between sleeve and bearing pin, increases moving particle abrasion；3. pair of friction components are single, no matter
The abrasion of bushed chain or roller chain, the part of final influence chain length is all sleeve and bearing pin, and current sleeve is
Linear joint form, because air line distance is short, therefore itself and the abrasion of bearing pin, roller are straight line abrasions, and abraded contact area is small,
Anti-wear difference, and because seam crossing is abrasion weak spot, after straight line abrasion, sleeve is easy to damage, and influences the use of chain
Life-span, for these reasons, it is necessary to carry out performance optimization to meet use demand to the chain of prior art.
Utility model content
In view of the shortcomings of the prior art, the utility model provide a kind of dust-proof wear-resisting chain, the chain have simple structure,
Reasonable in design, dust-proof, wear-resisting, antiseep, the advantage of long service life.
To realize utility model purpose, the utility model uses following technical scheme：
A kind of dust-proof wear-resisting chain, including several sleeves, inner plate, bearing pin, outer plate and roller, the sleeve interpolation
Bearing pin is provided with, the bush outer sleeve is provided with roller, is connected by the inner plate between the sleeve, and the bearing pin two ends are arranged
There is outer plate, the sleeve includes sleeve piece, and the sleeve piece is trapezoidal.
Preferably, the sleeve piece is in isosceles trapezoid.
Preferably, the upper base angle of the sleeve piece is 135 °.
Preferably, the inner side of the outer plate sets fluted, and the two ends of the sleeve are extended in groove, the exterior chain
Boss is provided with the outside of plate.
The beneficial effects of the utility model are：The utility model provides a kind of dust-proof wear-resisting chain, and the chain has knot
Structure is simple, reasonable in design, dust-proof, wear-resisting, antiseep, the advantage of long service life.
1st, the trapezoidal design of sleeve piece：Contribute to selection equipment to orient to select, be capable of achieving the assembled orientation technique of sleeve；
The direct abrasion of sleeve piece face and bearing pin is avoided, the anti-wear performance of chain is improved, the service life of chain is extended；
2nd, the extending design of sleeve：Chain link degree of being connected firmly is increased, chain link fatigue resistance is enhanced, chain link is improve
Extrusion pressure；
3rd, the groove design of outer plate：The effective silt for intercepting the external world is entered between sleeve and bearing pin, reduces fortune
Dynamic abrasion of particles；The distance between inner plate and outer plate are reduced, the flatness of chain is improve, sleeve and bearing pin is reduced
Between grease seepage flow, make chain link lubricate more fully, extend chain service life；
4th, the boss design of outer plate：The flow direction of metal and interior tissue is set not to be damaged in outer plate extrusion process used for forming
Wound, improves its mechanical performance；Increase aperture euphotic belt and aperture loaded area in exterior chain panel aperture extrusion process, so as to improve chain
The performance and anti-fatigue performance of bar.

Specific embodiment
The utility model is further described by specific embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of dust-proof wear-resisting chain, including several sleeves 1, inner plate 2, bearing pin 3, outer plate 4
With roller 5, it is inserted with the sleeve 1 outside bearing pin 3, the sleeve 1 and is arranged with roller 5, by described interior between the sleeve 1
Carrier bar 2 is connected, and the two ends of the bearing pin 3 are arranged with outer plate 4, and the sleeve 1 includes sleeve piece 6, and the sleeve piece 6 is in ladder
Shape, the sleeve piece 6 is in isosceles trapezoid, and the upper base angle of the sleeve piece 6 is 135 °, and the inner side of the outer plate 4 is set
Fluted 7, the two ends of the sleeve 1 are extended in groove 7, and the outside of the outer plate 4 is provided with boss 8.
Specific embodiment of the utility model is the foregoing is only, but architectural feature of the present utility model is not limited to
This, the utility model can be used on similar product, any those skilled in the art in field of the present utility model, institute
The change or modification of work are all covered among the scope of the claims of the present utility model.
