Description
Technical field
The utility model relates to chain drive component, particularly a kind of for powerdriven sleeve roller chain.
Background technique
Sleeve roller chain forms single-row or multiple row by inner plate, outer plate, sleeve, bearing pin, roller, outer plate is fixed on bearing pin, inner plate is fixed on sleeve, coaxial rotating linkage structure is all formed between roller and sleeve and between sleeve with bearing pin, chain is mainly rolling friction with engaging of sprocket wheel, thus bush roller chain is lightweight, the life-span is long, cost is low, be widely used in power transmission, if existing motorcycle and bicycle are all adopt the chain of single-row bush roller chain and sprocket wheel to carry out power transmission usually.Chaindriven failure mode mainly contains carrier bar fatigue ruption; Gummed, the chain hinge pin of the impact fatigue destruction of roller, sleeve, bearing pin and sleeve wear and tear, transship and break.Because first chaindriven meshing impact is born by roller and sleeve.Under repeated multiple times impact, through certain cycle-index, impact fatigue may occur for roller, sleeve destroys; And wearing and tearing are mechanically operated inevitable phenomenons, when exposed drive, Environmental Conditions inclement condition and insufficient lubrication, after chain wearing and tearing, chain link is elongated, easily causes and jumps tooth or de-chain, thus sharply reduce the working life of chain.The Chain conveyer of motorcycle belongs to typical exposed drive, and there is Environmental Conditions inclement condition and insufficient lubrication, therefore, failure mode be mainly manifested in chain link plate wearing and tearing and roller, sleeve impact fatigue destroy.When riding at upward slope and rugged section, these failure mode general performances are chain breakage, easily cause motorcycle glide or topple over, bring potential safety hazard to bicycler.For this reason, need to improve, to improve working life and the load capacity of existing motorcycle chain, effectively reduce riding safety hidden danger.
Summary of the invention
The purpose of this utility model is exactly the deficiency for existing bush roller chain, provides a kind of sleeve roller chain, and this chain is by the improvement to conventional sleeve roller chain, and its load capacity is strong, transmission efficiency is high, long service life.
For achieving the above object, the utility model adopts following technological scheme:
A kind of sleeve roller chain, comprise inner plate, outer plate, sleeve, bearing pin and the first roller, described sleeve has the extension of stretching out inner plate outer side surface described in both sides; Pin shaft hole medial extremity for being fixedly connected with described bearing pin on described outer plate is formed with expanding hole section, and this expanding hole section is formed with the corresponding extension of described sleeve and is rotatably connected.
Adopt the utility model of preceding solution, because sleeve has the extension of stretching out inner plate outer side surface described in both sides; Pin shaft hole medial extremity for being fixedly connected with described bearing pin on described outer plate is formed with expanding hole section, and this expanding hole section is formed with the corresponding extension of described sleeve and is rotatably connected.Therefore, this chain operationally, not only comprise the revolute pair formed between bearing pin and sleeve, also between outer plate and sleeve, form revolute pair, and the cylndrical surface of this revolute pair is sleeve outer diameter, the transmission of power between outer plate and inner plate is made not only to comprise traditional bearing pin and sleeve transmits, also add the transmission of outer plate directly and between sleeve, add power transmission link and increase transferring structure size, and the structure of this augmenting portion forms solid construction by the appropriate section of sleeve and bearing pin, significantly improve the load capacity of chain; Simultaneously, increase the revolute pair length between bearing pin and sleeve when identical roller length, improve abrasion resistance therebetween, extend working life, and delay the chain link elongated time by slowing down wearing and tearing, thus delay the speed of chain transmission decrease in efficiency.If suitably increase the thickness of outer plate, also significantly can promote aforementioned advantages, be specially adapted to the update to the chain of corresponding specification in existing machinery equipment.
Preferably, the expanding hole segment length on described outer plate is more than or equal to the extension length of described sleeve.To ensure the reasonable clearance between outer plate and inner plate, interior outer plate does not laterally channel bit, and runs without jam, guarantees chain transmission efficiency further.
Preferred further, described outer plate is made up of the first outer plate and the second outer plate, and the first outer plate is positioned at outside the second outer plate; The aperture section that described pin shaft hole coordinates with described bearing pin be clear opening structure be arranged on the first outer plate; Described expanding hole section is also clear opening structure and is arranged on the second outer plate.Process in the stamping-out carrier bar mode adopting manufacturing efficiency high, reduce manufacture cost.
Further preferred, the thickness of described second outer plate equals the length of extension on described sleeve.With while ensureing the reasonable clearance between outer plate and inner plate, the cylndrical surface length of thread engagement taken into account between the second outer plate and sleeve maximizes, and guarantees chain load ability and working life further.
Through experimental verification, the bush roller chain of the two outer plate of employing of the present utility model is compared with the bush roller chain of conventional construction same size, and its load capacity can improve 70 ~ 100%, under the same load, its life-span can improve nearly one times, effectively can reduce user cost.
The beneficial effects of the utility model are, by the powerdriven reallocation of internal outer plate, slow down the connection wearing and tearing of chain, significantly improve the load energy of bush roller chain, extend working life, and then reduce user cost.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but be not therefore limited among described scope of embodiments by the utility model.
See Fig. 1, Fig. 2, a kind of sleeve roller chain, comprise inner plate 1, outer plate, sleeve 3, bearing pin 4 and the first roller 5, described sleeve 3 has the extension of stretching out inner plate 1 outer side surface described in both sides; Described outer plate forms by by the first outer plate 21 and the second outer plate 22, and the first outer plate 21 is positioned at outside the second outer plate 22; Pin shaft hole medial extremity for being fixedly connected with described bearing pin 4 on outer plate is formed with expanding hole section; Wherein, the aperture section that pin shaft hole coordinates with described bearing pin 4 be clear opening structure be arranged on the first outer plate 21; Expanding hole section is also clear opening structure and is arranged on the second outer plate 22, thus the thickness forming the second outer plate 22 equals the length of extension on described sleeve 3; This expanding hole section is formed with the corresponding extension of described sleeve 3 and is rotatably connected.
In the present embodiment, the second outer plate 22 suitably can be greater than the length of expanding hole section, can improve two degree of compacting between outer plate and inner plate, guarantee that transmission efficiency is high; Certainly, two outer plates also can only as one, when the two is integrated, although increase manufacture difficulty, its load capacity, transmission efficiency and working life aspect effect can be more remarkable.
