Component is also being continuously improved.
Standard bicycle chain is connected in series in the form of kinematic pair by the identical or identical inner link in interval and outer link
Sub-assembly suffer from and be widely applied in each field due to the characteristics of having gear drive and V belt translation concurrently.Existing chain exists
When contacting with bicycle gears during use, it can occur to deviate relatively at the roller in chain link, to the roller part of chain
It causes to wear, it usually needs artificial oil is maintained, and the service life of chain otherwise can be reduced because of oil starvation, while also can shadow
Ring the reliability of chain drive.
Utility model content
Roller part can be avoided to wear needs in order to solve the above technical problems, the purpose of this utility model is to provide one kind
The long-life chain of hand oiling maintenance.
The technical solution of the utility model is as follows：
A kind of long-life chain that can avoid abrasion, including multiple outer links (1) and inner link (2)；The outer link
(1) include outer plate (11), the both ends of the outer plate (11) are arranged with cylindricality counter sink (12), inner link (2) packet
Include inner plate (21), sleeve (22) and roller (23), inner plate (21) both ends are arranged with through-hole, the sleeve (22) with
The inner plate (21) is arranged by interference connection in the through-hole, and the roller (23) is arranged around the sleeve (22),
Its center is equipped with cricoid limiting groove (231), and outside is equipped with wearing layer (24)；The sleeve (22) and the cylindricality counter sink
(12) diameter is identical, and the outer link (1) and inner link (2) are by running through the cylindricality counter sink (12), sleeve (22)
Axis pin (3) is connected in the form of hinges, is arranged around the axis pin (3) between the outer plate (11) and inner plate (21)
There is bearing (4).
Further, the both ends of the axis pin (3) are equipped with flange (31), and the flange is arranged in the cylindricality counter sink
(12) in.
Further, the wearing layer (24) is ceramic material.
Further, the bearing (4) is deep groove ball bearing.
According to the above aspect of the present invention, the beneficial effects of the utility model are：
(1) center portion of roller is equipped with cyclic annular limiting groove in the present apparatus, can make to contact more between chain and gear
Add reliably, avoiding shifting between chain and gear occurs chain phenomenon, ensures traveling reliability；
(2) it is equipped with ceramic wearing coat on the outside of roller, the abrasion of gear mesh roller can be effectively reduced, reduces manually to chain
Maintenance, extend the service life of chain；
(3) deep groove ball bearing is set between inner link and outer link outside axis pin, radial load can not only be born, also may be used
Certain axial load is born, when opposite offset occurs between chain and gear, can effectively cut down radial and axial load,
Reduce the abrasion at axis pin in chain, extends chain service life.
The utility model is designed reasonably, it is simple in structure, chain phenomenon can not only be effectively avoided, ensures bicycle running
Reliability, while the abrasion of chain hinge pin and roller can be effectively avoided, extend the service life of product.
Description of the drawings
