Abstract
The utility model discloses a chain, and includes two inner chain slices, two outer chain slices which are relative to the two inner chain slices, a pin shaft penetrates through the inner chain slices, and connects with the outer chain slices, a lining connected with two inner chain slices and sleeved with the pin shaft, a chain roll sleeved on the outer surface of the lining, a connecting hole that the outer chain slices connect with the pin shaft is a long hole, the shape of the two outer ends of the pin shaft is adapted with the connecting hole of the outer chain slice, the connecting hole that the inner chain slices connect with the lining is a long hole, the shape of the two outer ends of the lining is adapted with the connecting hole of the inner chain slice; thereby the outer chain slice and the pin shaft can not produce rotation, and the inner chain slice and the lining can not produce rotation. Therefore, the pin shaft and the connecting hole of the outer chain slice can not abrade, and lining and the connecting hole of the inner chain slice can not abrade, so as to reduce the extension volume of the chain during application process, then the service life of the chain can be prolonged, the cost can be saved, and the safe and reliable operation of relative driving components can be guaranteed.
Description
Technical field
The utility model relates to a kind of chain, relates in particular to a kind of sleeve roller chain.
Background technique
Chain is widely used in as a kind of driving component flexibly on the power transmission of bicycle, locomotive and machinery, and at present, the revolute pair of employed each chain link of chain is easy to wearing and tearing, makes the chain elongation, has reduced the working life of chain.When on the refiner of textile manufacturing machine, using chain, usually because the wearing and tearing of the revolute pair of chain link, make the chain elongation, not only cause net fail in tension, and cause holder net axle not corresponding with holder net roller pitch, and produce off-axis or disconnected clamp, cause enormous economic loss to production, strengthened workman's workload, manufacturing efficiency is reduced.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of chain is provided, after the revolute pair wearing and tearing that solve chain link, makes the technical problem of chain elongation.
For achieving the above object, the technical solution of the utility model is: chain, comprise the chain link that several are linked in sequence, wherein each chain link comprises two inner chain sheets, each inner chain sheet outside is respectively equipped with an outer chain sheet, pass described inner chain sheet and connect the bearing pin of described outer chain sheet, be connected and be sheathed on the lining of described bearing pin with described two inner chain sheets, the chain that is set on the outer surface of described lining rolls, the attachment hole that described outer chain sheet is connected with bearing pin is a slotted hole, and the shape of the shape of described bearing pin two outer ends and the attachment hole of described outer chain sheet is suitable.
As a kind of improvement, the attachment hole that described inner chain sheet is connected with lining is a slotted hole, and the shape of the shape of described lining two outer ends and the attachment hole of described inner chain sheet is suitable.
Owing to adopt technique scheme, chain, comprise the chain link that several are linked in sequence, wherein each chain link comprises two inner chain sheets, each inner chain sheet outside is respectively equipped with an outer chain sheet, pass described inner chain sheet and connect the bearing pin of described outer chain sheet, be connected and be sheathed on the lining of described bearing pin with described two inner chain sheets, the chain that is set on the outer surface of described lining rolls, the attachment hole that described outer chain sheet is connected with bearing pin is a slotted hole, and the shape of the shape of described bearing pin two outer ends and the attachment hole of described outer chain sheet is suitable; So outer chain sheet and bearing pin can not rotate, thereby can not wear and tear between the attachment hole of bearing pin and outer chain sheet, thereby reduced chain elongation in use, increased the working life of chain, saved cost, improve manufacturing efficiency, guaranteed the safe and reliable operation of corresponding transmission part.
The attachment hole that described inner chain sheet is connected with lining is a slotted hole, and the shape of the shape of described lining two outer ends and the attachment hole of described inner chain sheet is suitable; So inner chain sheet and lining can not rotate, thereby can not wear and tear between the attachment hole of lining and inner chain sheet, thereby reduced chain elongation in use, increased the working life of chain, saved cost, improve manufacturing efficiency, guaranteed the safe and reliable operation of corresponding transmission part.
