Abstract
The utility model relates to a double pin axle tooth-shaped chain. A one hole double axle structure is adopted, two pin axles are arranged in the pin axle holes of an inner piece and a circular arc inner piece, the pin axle is divided into a short pin axle and a long pin axle, the two pin axles are cone equiangular triangle axles with identical cross section; the noncircular pin axle holes of the inner piece and the circular arc inner piece are long oval shaped, the pin axle hole of an outer piece is identical to the cross section of the long pin axle, thus, the long pin axle and the outer piece are not moved relatively, and the working stability of the tooth-shaped chain is increased; the inner piece and the circular arc inner piece are staggered, overlapped and arranged, and the outer pieces are arranged on the both outer sides of the tooth-shaped chain, correspond to the inner piece and are arranged in parallel orderly. When the utility model moves, the circular surfaces of the two pin axle slide, the attrition in the transmission process is effectively reduced, the noise is reduced, the service life is improved remarkably, and the utility model is suitable for a digital machine, a vehicle, a frequent start-up machine and other high-end machines.
Description
Technical field
The utility model relates to a kind of chain, especially a kind of double-pin axle silent chain.
Background technique
In machinery employed mostly in the contact-type silent chain, adopt round pin axle and multi-disc tooth shape chain sheet with the form of the pin hinge pair composition flexible element that is together in series, the shortcoming of this chain be chain enter engagement moment since the internal tooth of chain sheet contact with sprocket wheel, and make the chain sheet that a trend of upwards scurrying be arranged, make chain cause bob, thereby can produce serious impact, vibration and noise at the lower chain that runs up.The patent No. is 03229077.2 the disclosed spacing silent chain of Chinese patent, it is made up of chain sheet and the special-shaped D type pin shaft hole of being located on the chain sheet, be provided with D type bearing pin in the D type pin shaft hole, the chain sheet is divided into two kinds of locate chain sheet and connection chain sheets, each chain link is composed in series with D type bearing pin by one group of overlapping chain sheet, and adjacent two chain sheets are to be staggered with locate chain sheet and connection chain sheet.Two pin shaft holes on the locate chain sheet are the same with the shape of D type bearing pin, D type bearing pin and locate chain sheet do not have relative movement like this, be provided with an angle between two pin shaft holes of connection chain sheet and the D type bearing pin, connection chain sheet and D type bearing pin rotated have directivity and positional.This structure has certain effect on minimizing noise and raising stationarity, but the wearing and tearing in its work are still very big, and working life is undesirable.
Summary of the invention
Wearing and tearing were little when the purpose of this utility model was a kind of work of design, noise is low, the double-pin axle silent chain of long service life, stable working.The technical solution of the utility model is so to realize:
A kind of double-pin axle silent chain, comprise with the chain sheet of special-shaped pin shaft hole (6) and be located at bearing pin in the pin shaft hole (6), described chain sheet is divided into sheet (3) in outer plate (1), interior sheet (2) and the circular arc, described bearing pin is divided into the identical short pin shaft in cross section (5) and has strong market potential axle (4), both are located in interior sheet (2) and the circular arc in the pin shaft hole (6) on the sheet (3) simultaneously, interior sheet (2) and interior sheet (3) staggered overlapping arrangement of circular arc, outer plate (1) is located at two outsides of silent chain, corresponding with interior sheet (2), be arranged in parallel successively.
As preferably, the described short pin shaft (5) and the axle (4) of having strong market potential are conical surface equilateral triangle axle.
As preferably, the shape of the pin shaft hole (6) on the described outer plate (1) is consistent with the sectional shape of the axle (4) of having strong market potential, the pin shaft hole (7) on the interior sheet (3) of interior sheet (2) and circular arc be shaped as oblong.
The utility model adopts the structure of a hole twin shaft, is equipped with two bearing pins in the pin shaft hole (6) of sheet (3) in interior sheet (2) and the circular arc, and bearing pin is divided into a long and short two bearing pin, and both are the identical conical surface equilateral triangle axle in cross section; The special-shaped pin shaft hole (6) of sheet (3) is an oblong in interior sheet (2) and the circular arc, the pin shaft hole (6) of outer plate (1) is consistent with the sectional shape of the axle (4) of having strong market potential, make have strong market potential in the working procedure axle (4) and the no relative movement of outer plate (1) like this, increase the stable working of silent chain; Interior sheet (2) and interior sheet (3) staggered overlapping arrangement of circular arc, outer plate (1) is located at two outsides of silent chain, and is corresponding with interior sheet (2), is arranged in parallel successively.The utility model is that the arc surface of two bearing pins slides when motion, has effectively reduced the wearing and tearing in the transmission process, and noise is reduced, and be significantly improved working life.The utlity model has that wearing and tearing are little, noise is low, the characteristics of long service life, stable working.The utility model is applicable to that numerical controlled machinery, automobile, the contour terminal tool of frequent starting machinery use.

Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is structural representations of sheet in the utility model;
Accompanying drawing 3 is structural representations of the utility model outer plate.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings 1, accompanying drawing 2, accompanying drawing 3, a kind of double-pin axle silent chain, comprise with the chain sheet of special-shaped pin shaft hole (6) and be located at bearing pin in the pin shaft hole (6), the chain sheet is divided into outer plate (1), sheet (3) in interior sheet (2) and the circular arc, bearing pin is divided into the identical short pin shaft in cross section (5) and has strong market potential axle (4), both are conical surface equilateral triangle axle, and be located at simultaneously in the pin shaft hole (6) on the interior sheet (3) of interior sheet (2) and circular arc, the shape of the pin shaft hole (6) on the outer plate (1) is consistent with the shape in single bearing pin cross section, the pin shaft hole (7) in interior sheet (2) and the circular arc on the sheet (3) be shaped as oblong.
Interior sheet (2) and interior sheet (3) staggered overlapping arrangement of circular arc, outer plate (1) is located at two outsides of silent chain, and is corresponding with interior sheet (2), is arranged in parallel successively.
In the working procedure, have strong market potential axle (4) and the no relative movement of outer plate (1) have increased the stable working of silent chain; The transmission of silent chain is that the conical surface of diaxon slides, because be that two circular arcs slide, the wearing and tearing when having effectively reduced transmission reduce noise, make working procedure steady, and have improved working life to a great extent.
