Abstract
The invention discloses silent chain outer plate piece type structure designs, including silent chain outer plate ontology, the silent chain outer plate ontology lower end is at ellipse arc, it is arc-shaped at left and right sides of the silent chain outer plate ontology upper end, one group of arc-shaped centre is connected by excessive arc, and a pair of of pin hole is symmetrically provided on the silent chain outer plate ontology.The beneficial effects of the invention are as follows, improve the intensity of silent chain outer plate, it is more smooth with chain interoperation when gear operation, it changes outer plate inside edge and scratches or block the phenomenon that hindering by engine gear crown, reduce engine noise, the service life of chain is improved, and has the characteristics that lightweight, it is highly practical.
Description
Technical field
The present invention relates to machine components equipment design fields, especially silent chain outer plate piece type structure design.
Background technology
Silent chain is also known as silent chain（Silent Chain）, belong to a kind of form of transmission chain.The national standard in China is：
GB/T10855-2003《Tooth form chain and sprocket》.Silent chain is a kind of widely used important mechanical basic part, is used primarily in height
Speed, heavy duty, low noise, big centre-to-centre spacing operating mode under, transmission performance is passed better than tooth form V belt translation, gear drive and roller chain
It is dynamic, to become numerous industry first choices to one of driving form, internal messing silent chain, external toothing tooth form can be divided into mesh form point
Chain and inside and outside compound engaging tooth shape chain, wherein the noise of inside and outside compound engaging tooth shape chain is minimum, using also most extensive.
And existing silent chain outer plate（As shown in Figure of description 2-4）After being assembled with chain, chain engages biography with gear
Dynamic operating, engine gear is non-coplanar, and crown is easy to scratch or card hinders the (shade as shown in Figure of description 2-4 on the inside of outer plate
Place), to which engine can be made to generate abnormal sound, reduce the service life of chain.
Invention content
The purpose of the present invention is to solve the above problems, devise silent chain outer plate piece type structure design.
Realize above-mentioned purpose the technical scheme is that, silent chain outer plate piece type structure design, including silent chain outer plate
Ontology, at ellipse arc, the silent chain outer plate ontology upper end left and right sides is circular arc for the silent chain outer plate ontology lower end
Shape, one group of arc-shaped centre are connected by excessive arc, and a pair of of pin hole is symmetrically provided on the silent chain outer plate ontology.
The arc-shaped radian is 210 degree of 180 degree-.
The arc-shaped radian is 200 degree.
The cross section of the pin hole is circle.
The cross section of the excessive arc is arc-shaped.
The silent chain outer plate piece type structure design made using technical scheme of the present invention, waist width are widened, and tooth form is improved
The intensity of chain outer plate engages point of penetration diminution with gear, more smooth with chain interoperation when making its gear operation, changes in outer plate
Lateral edges scratch or block the phenomenon that hindering by engine gear crown, reduce engine noise, improve the service life of chain,
And have the characteristics that lightweight, it is highly practical.

Specific implementation mode
It should be noted that：Similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined, then it further need not be defined and explained in subsequent attached drawing in a attached drawing.
In the description of the present invention, it should be noted that the orientation or position of the instructions such as term "upper", "lower", "left", "right"
Set relationship be based on the orientation or positional relationship shown in the drawings or the invention product using when the orientation or position usually put
Relationship is set, is merely for convenience of description of the present invention and simplification of the description, device is not indicated or implied the indicated or element is necessary
With specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
The present invention is specifically described below in conjunction with the accompanying drawings, as shown in figs. 1-7, silent chain outer plate piece type structure design,
Including silent chain outer plate ontology（1）, the silent chain outer plate ontology（1）Lower end is at ellipse arc（2）, the silent chain outer plate sheet
Body（1）It is arc-shaped at left and right sides of upper end（3）, described one group arc-shaped（3）Centre passes through excessive arc（4）It is connected, the tooth
Shape chain outer plate ontology（1）On be symmetrically provided with a pair of of pin hole（5）；It is described arc-shaped（3）Radian be 210 degree of 180 degree-；The circle
Arc（3）Radian be 200 degree；The pin hole（5）Cross section be circle；The excessive arc（4）Cross section be it is arc-shaped.
The characteristics of the present embodiment is that silent chain outer plate ontology lower end engages point of penetration diminution with gear at ellipse arc,
It is more smooth with chain interoperation when making its gear operation, it changes outer plate inside edge and scratches or block wound by engine gear crown
Phenomenon reduces engine noise, improves the service life of chain, is circular arc at left and right sides of silent chain outer plate ontology upper end
Shape, one group of arc-shaped centre are connected by excessive arc, and waist width is widened, and the intensity of silent chain outer plate is improved.
In the present embodiment, multiple silent chain outer plate ontologies are connected in turn by pin hole when use, excessively
The wide increasing of waist formed between arc and ellipse arc, improves the intensity of silent chain outer plate when in use, and lower end uses elliptic arc
Shape, which is reduced, engages point of penetration with gear, more smooth with chain interoperation when gear operation in use, reduces in outer plate
Lateral edges scratch or block the phenomenon that hindering by engine gear crown, to improve the service life of chain, and reduce
Engine noise, and have the characteristics that lightweight, it is highly practical.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of which part may be made, belongs to the scope of protection of the present invention it
It is interior.
