Abstract

The utility model discloses a self-lubricated speed-doubling chain which comprises an outer chain plate, an inner chain plate and a pin shaft. The outer chain plate is arranged on the outer side of the inner chain plate; the pin shaft horizontally penetrates through the inner chain plate and the outer chain plate and is fixed on the outer side of the outer chain plate; the outer side of the pin shaft is provided with a large roller, and two sides of the large roller are respectively provided with small rollers; two sleeves are arranged between the large roller and the pin shaft and are mutually contacted; the outer sidewalls of the other ends of the sleeves are contacted with the inner chain plate; and the sum of the lengths of the two sleeves is equal to the distance between two symmetric inner side faces of the outer chain plate. When the self-lubricated speed-doubling chain is used, dry friction caused by direct contact between the pin shaft and the inner chain plate can be avoided, and the wear resistance of the pin shaft can be improved. Moreover, since the sum of the lengths of the two sleeves is equal to the distance between the two symmetric inner side faces of the outer chain plate, the smoothness of a chain framework can be ensured in a favorable mode, meanwhile, direct contact between the outer chain plate and the inner chain plate can be avoided, and the service life of the chain can be greatly prolonged.

Description

A kind of self-lubricating type double-speed chain
Technical field
The utility model relates to a kind of double-speed chain, relates in particular to a kind of self-lubricating type double-speed chain of chain long service life.
Background technique
At present, be used for the traditional High speed chain on the automation production flow line, formed by six kinds of parts such as inner plate, sleeve, plastics small roller, band step plastics large roller, outer plate, bearing pins mostly, its working principle is: article are placed on the large roller and carry, small roller orbits, drive the large roller motion by small roller and the contact friction of large roller stepped portions, and according to the external diameter of big small roller than playing doubly fast acting on.This double-speed chain need often refuel maintenance, guarantees the working life of chain.If adopt drop lubrication or Sump lubrication, not only increased equipment cost, and the lubricant oil that adheres to thereon can be scattered for four times, in the time of befouling environment, also can increase extra environment maintenance expense.Prior, if lubricant oil enters between the big small roller, will cause small roller and large roller stepped portions to be skidded mutually, can't drive the large roller operation, make to be transferred the effect that article can't reach speedup.
The model utility content
The utility model purpose is the self-lubricating type double-speed chain that a kind of chain long service life is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of self-lubricating type double-speed chain, comprise outer plate, inner plate and bearing pin, and described outer plate is arranged on the outside of inner plate; Described bearing pin crosses inner plate and outer plate, and is fixed on the outside of outer plate; The arranged outside of described bearing pin has large roller, and the both sides of described large roller are respectively arranged with small roller; Be provided with two sleeves between described large roller and the bearing pin, and described sleeve contacts with sleeve; The outer side wall of the described sleeve the other end contacts with inner plate.
Preferably, the length sum of described two sleeves equals two distances between the symmetrical outer plate inner side surface.
Preferably, described large roller and small roller are made of plastics.
` is owing to the utilization of technique scheme, and the utility model compared with prior art has following advantage:
The self-lubricating type double-speed chain of the utility model scheme, because the arranged outside of described bearing pin has large roller, and the both sides of described large roller are respectively arranged with small roller; Be provided with two sleeves between described large roller and the bearing pin, and described sleeve contacts with sleeve; The outer side wall of the described sleeve the other end contacts with inner plate.Self-lubricating type double-speed chain described in the utility model has been avoided directly contacting and dry friction between bearing pin and the inner plate in the process of using, and has improved the wear-resisting property of bearing pin; Simultaneously the length sum of described two sleeves equals two distances between the symmetrical outer plate inner side surface, is conducive to guarantee the stationarity of chain framework, has prevented simultaneously that with it outer plate from directly contacting with inner plate, has improved chain working life greatly.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the partial structurtes schematic representation of self-lubricating type double-speed chain described in the utility model;
Wherein: 1, outer plate; 2, inner plate; 3, bearing pin; 4, large roller; 5, small roller; 6, sleeve.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As accompanying drawing 1 described a kind of self-lubricating type double-speed chain of the present utility model, comprise outer plate 1, inner plate 2 and bearing pin 3, described outer plate 1 is arranged on the outside of inner plate 2; Described bearing pin 3 crosses inner plate 2 and outer plate 1, and is fixed on the outside of outer plate 1; The arranged outside of described bearing pin 3 has large roller 4, and the both sides of described large roller 4 are respectively arranged with small roller 5; Be provided with two sleeves 6 between described large roller 4 and the bearing pin 3, and described sleeve 6 contacts with sleeve 6; The outer side wall of described sleeve 6 the other ends contacts with inner plate 2; The length sum of described two sleeves 6 equals two distances between symmetrical outer plate 1 inner side surface; Described large roller 4 and small roller 5 are made of plastics.
Its sleeve 6 of the described self-lubricating type double-speed chain of model utility is powder metallurgy sleeve.Powder metallurgy sleeve is produced through operations such as batching, press forming, sintering, heat treatment, oilings with metallic dust, contain a certain amount of lubricant oil in the powder metallurgy sleeve of finished product, chain is in running, by sleeve 6 and bearing pin 3, sleeve 6 and large roller 4 these two pairs of friction pairs sleeve 6 is rubbed, oil in the sleeve 6 is sucked out in the chain movement process owing to siphon principle, between two pairs of friction pairs, form oil film, thereby reach self-lubricated purpose.
Self-lubricating type double-speed chain described in the utility model has been avoided directly contacting and dry friction between bearing pin 3 and the inner plate 2 in the process of using, and has improved the wear-resisting property of bearing pin 3; Simultaneously the length sum of described two sleeves 6 equals two distances between symmetrical outer plate 1 inner side surface, is conducive to guarantee the stationarity of chain framework, has prevented simultaneously that with it outer plate 1 from directly contacting with inner plate 2, has improved chain working life greatly.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
