Description
Technical field
The utility model relates to a kind of chain, especially a kind of low-noise chain.
Background technique
Chain transmission is carried out between the sprocket wheel of setting, chain-driven is a kind of non-conjugated engagement driving with middle flexible element, because the engagement of the roller chain and sprocket in the chain-driven is non-conjugated engagement, will inevitably produce vibration and noise at work, thereby its application is subjected to certain limitation.At present, chaindriven noise reduction has been taked various measures both at home and abroad, effect also is not quite similar.Controlling noise can be by changing sprocket wheel or chain structure to slow down the method for mesh impact, Chinese patent ZL01124922.6 discloses a kind of low noise roller chain, its metal rigidity roller and elastic roller join end to end and are fixed on the lining, be that elastic roller is the word arrangement that the longitudinal direction along chain is, vibration damping and the effect that reduces noise are played in being arranged in so to a certain extent, but the cost of wasting time and energy when installing is higher, and the accuracy aspect is installed to acquire a certain degree of difficulty, in addition because elastic material is wrapped in rigidity roller outside, its width will become greatly when stressed in working order, thereby effect and the stable working that reduces noise had certain influence.In sum, the noise how efficiently and effectively reduces in the chain transmission process just seems that realistic meaning is arranged very much.
Summary of the invention
A purpose of the present utility model is exactly on the basis of former invention, makes the work of chain more steady, noise-decreasing better effects if, and the life-span of as far as possible improving chain.The technical solution of the utility model is so to realize:
A kind of low-noise chain, comprise inner link, outside links and the roller assembly of forming by rigidity roller (2) and elastic roller (1) (7), each inner link all has two sleeves (4) and a pair of inner plate (3) interference fit, each outside links all has two bearing pins (5) and a pair of outer plate (6) interference fit, rigidity roller (2) outer peripheral surface is provided with the groove of suit elastic roller (1), and the degree of depth of described groove (12) is 50%～100% of rigidity roller (a 2) wall thickness.
As preferably, the width w of elastic roller (1) accounts for 30%～50% of whole roller assembly (7) width W.
As preferably, the difference of the outside diameter d of the outer diameter D of elastic roller (1) and rigidity roller (2) is 5%～10% of rigidity roller (a 2) outside diameter d.
As preferably, the degree of depth of groove (12) is 100% of rigidity roller (a 2) wall thickness, and promptly rigidity roller (2) is divided into two sections, in the middle of elastic roller (1) places, directly is sleeved on sleeve (4) periphery.
The utility model is primarily aimed at roller assembly (7) and has carried out structure improvement, has designed a kind of new structure that elastic roller (1) is placed rigidity roller (2) centre.Its principle that reduces noise is, when chain and sprocket tooth impact engagement, because the outside dimension of elastic roller (1) is greater than rigidity roller (2), thereby at first contact with the sprocket tooth impact, in impacting contact process, because elastic roller (1) has elasticity, so when being compressed to a certain degree, sprocket tooth just begins to contact with rigidity roller (2), during the elastic roller (1) that contacted earlier of impact cushion, the contact process of sprocket tooth and elastic roller (1) is noise reduction process.In most preferred embodiment, roller surface is divided into three sections, and when middle elastic roller was out of shape in working order, the rigidity roller on both sides had the effect of a restriction to its width, thereby, improve stationarity and durability.Compared with prior art, the utlity model has characteristics such as rational in infrastructure, easy for installation, that use is reliable and stable.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
A kind of structural representation of accompanying drawing 2 the utility model most preferred embodiments.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment 1: with reference to the accompanying drawings 2, and chain comprises inner link, outside links and roller assembly (7).Each inner link all has two sleeves (4) and a pair of inner plate (3) interference fit, and each outside links all has two bearing pins (5) and a pair of outer plate (6) interference fit.Roller assembly (7) comprises the rigidity roller (2) of recessing on the outer peripheral surface (12) and places the interior elastic roller (1) of groove (12), elastic roller (1) is made by abrasive synthetic rubber, they are mounted in pairs on the sleeve (4), the degree of depth of groove (12) is 100% of rigidity roller (a 2) wall thickness, be that rigidity roller (2) is divided into two sections, in the middle of elastic roller (1) places, directly be sleeved on sleeve (4) periphery, with the 08ALN chain is example, elastic roller (1) outer diameter D is 8.15mm, the outside diameter d of rigidity roller (2) is 7.72mm, the difference of the outside diameter d of the outer diameter D of elastic roller (1) and rigidity roller (2) is 5% of rigidity roller (a 2) outside diameter d, the width W of roller assembly (7) is 7.85mm, and elastic roller (1) width w is 2.74mm, and elastic roller (1) width w accounts for 34.9% of roller assembly (7) width W.
During work, because the outside dimension of elastic roller (1) is greater than rigidity roller (2), thereby at first contact with the sprocket tooth impact, in impacting contact process, because elastic roller has elasticity, so when being compressed to a certain degree, sprocket tooth just begins to contact with rigidity roller (2), the elastic roller (1) that contacted earlier of impact cushions during this time, an impulse noise acoustic energy part changes into the heat energy of elastic roller (1), improved lubricating condition to a certain extent, made that the whole more stable work of chain is reliable.
Present embodiment is a most preferred embodiment.
Embodiment 2: with reference to the accompanying drawings 1 and embodiment 1, the degree of depth of the groove (12) of rigidity roller (2) is 60% of rigidity roller (a 2) wall thickness, with the 10ALN chain is example, elastic roller (1) outer diameter D is 10.40mm, the outside diameter d of rigidity roller (2) is 9.85mm, the difference of the outside diameter d of the outer diameter D of elastic roller (1) and rigidity roller (2) is 5% of rigidity roller (a 2) outside diameter d, the width W of roller assembly (7) is 9.40mm, elastic roller (1) width w is 3.12mm, and elastic roller (1) width w accounts for 33.19% of roller assembly (7) width W.
Other reference example 1 is identical with embodiment 1.
