The tooth-shaped chain has the advantages that when in transmission process, two gearing mechanisms, namely an external gearing mechanism and an internal-external compound gearing mechanism, are adopted to form alternate compound gearing tooth-shaped chain transmission in certain order and according to certain rules, shock and vibration are reduced, the noise is reduced, the wear resisting property and the transmission efficiency are improved, and the tooth-shaped chain can satisfy the high performance requirements of different host machines under different working conditions through optimization and adjustment of the arrangement rules.
Description
Technical field
The utility model belongs to silent chain transmission system, is specifically related to a kind of silent chain that is applicable to the variable load variable speed drive, especially is applicable to the silent chain transmission of oil-well rig, metallurgical machinery, chemical machinery, generator set and speed changer, transfer case etc.
Background technique
Silent chain is a kind of widely used important mechanical basic part, and at present, the silent chain that is applicable to high speed driving unit is outer meshing silent chain and interior-outer compound engaging tooth shape chain.When outer meshing silent chain refers to silent chain and sprocket engagement, only have the outside straight-side profile of work carrier bar and the silent chain of sprocket teeth engagement, contact stress is less, positioning stablity, but owing to finish instantaneous the contact location, thereby polygon effect is serious, shock and vibration are larger, and noise is large, and wearing and tearing are heavy, transmission efficiency is lower, and easy-rupturing lost efficacy; In-when outer compound engaging tooth shape chain refers to silent chain and sprocket engagement, the inboard evagination flank profil of its work carrier bar meshes with sprocket teeth first, continuous increase along with corner between the adjacent link, be converted into by outside straight-side profile and sprocket teeth engagement, until realize outer gearing by inboard evagination flank profil gradually.Interior-outer compound engaging tooth shape chain is compared with outer meshing silent chain and more is applicable to high-speed drive, has reduced polygon effect, has reduced shock and vibration, has reduced noise, has improved transmission efficiency.But in heavy duty, at a high speed, under the operating mode of variable load speed change and large centre distance, as: in the chain transmission of oil-well rig, metallurgical machinery, chemical machinery, generator set and speed changer, transfer case etc., noise will strengthen, and wearing and tearing are accelerated, transmission efficiency reduces, and can not satisfy the high performance requirements of main frame.
Summary of the invention
The problems referred to above that exist in order to overcome the prior art field, the purpose of this utility model is, a kind of silent chain that is applicable to the variable load variable speed drive is provided, solves existing silent chain transmission efficiency and reduce, quick abrasion and can not satisfy the problem of main frame high performance requirements.
The silent chain that is applicable to the variable load variable speed drive that the utility model provides, it comprises pair of sprocket, chain, chain and sprocket engagement, described chain comprises outer gearing link set, interior-outer compound engagement link set, two kinds of link set alternative arrangements.The chain link quantitative proportion of the outer gearing link set of described chain and interior-outer compound engagement link set is the outer gearing chain link: interior-outer compound engagement chain link: the outer gearing chain link: interior-outer compound engagement chain link: the outer gearing chain link: interior-outer compound engagement chain link: the outer gearing chain link: interior-outer compound engagement chain link=1: 6: 2: 9: 3: 7: 2: 4.
The silent chain that is applicable to the variable load variable speed drive that the utility model provides, its beneficial effect is, compare with interior-outer compound engaging tooth shape chain with outer meshing silent chain, this silent chain is when transmission, have simultaneously outer gearing and interior-two kinds of mesh mechanisms of outer compound engagement concurrently, and be to arrange the silent chain transmission that alternately mixes engagement that forms with rule in certain sequence, shock and vibration have been reduced, reduced noise, improve its wear-resisting property and transmission efficiency, and can satisfy the high performance demands of different main frames under different operating modes by optimizing and revising its ordered arrangement rule.

Embodiment
With reference to the accompanying drawings, in conjunction with the embodiments, the silent chain that is applicable to the variable load variable speed drive to the utility model provides is described in detail.
Embodiment
With reference to Fig. 1-Fig. 4, the silent chain that is applicable to the variable load variable speed drive of present embodiment, it comprises pair of sprocket 4, chain, chain and sprocket wheel 4 engagements, described chain comprises outer gearing link set, interior-outer compound engagement link set, two kinds of link set alternative arrangements.The chain link quantitative proportion of the outer gearing link set of described chain and interior-outer compound engagement link set is the outer gearing chain link: interior-outer compound engagement chain link: the outer gearing chain link: interior-outer compound engagement chain link: the outer gearing chain link: interior-outer compound engagement chain link: the outer gearing chain link: interior-outer compound engagement chain link=1: 6: 2: 9: 3: 7: 2: 4.
The total joint number of described silent chain is 68 joints, namely formed by 68 chain links, per 34 pitch chains joint is a circulation, chain link is combined into a circulation according to aforementioned proportion, described outer gearing chain link comprises work carrier bar 1, guide plate 3, work carrier bar 1 is connected with guide plate 3 by bearing pin, and described work carrier bar 1 is outer gearing work carrier bar.In described-and outer compound engagement chain link comprises work carrier bar 2, guide plate 3, and work carrier bar 2 is connected with guide plate 3 by bearing pin, and described work carrier bar 2 is interior-outer compound work carrier bar.
During the speed changer running, outer gearing chain link work carrier bar 1 and interior-outer compound engagement chain link working chain plate 2 alternately carry out engagement driving with sprocket wheel, make this silent chain have the advantage of outer meshing silent chain and interior-outer compound engaging tooth shape chain concurrently, both realized that contact stress was less, positioning stablity increases the load of transmission and moment of torsion, reduced again polygon effect, reduce shock and vibration, reduced noise, improved transmission efficiency.Adopt computer simulation technique to simulate under certain condition, namely in load, rotating speed, under the certain condition that variable load speed change and transmission centre distance etc. present, pass through optimal design, find the solution outer gearing work carrier bar 1 and interior-outer compound joggleword carrier bar 2 alternative arrangement combination parameters, and adjust its ordered arrangement rule and satisfy the high performance demands of different speed changers under different operating modes, the permutation and combination form that is to say this silent chain chain link can be according to different customer requirements, adjust, satisfying different clients' individual demand, thereby realized in heavy duty, at a high speed, variable load gear under the operating mode of variable load speed change and large centre distance.
