Abstract
The utility model provides a kind of trailer coupling, comprising: the first driving wheel, the second driving wheel and driving band; It is characterized in that, this driving band being wrapped on this first driving wheel and the second driving wheel is S-type, makes the direction of rotation of this first driving wheel and this second driving wheel.The trailer coupling that the utility model provides is by S-type by the driving band 30 being wrapped on this first driving wheel 11 and the second driving wheel 12, increase driving band and enclose cornerite degree on driving wheel, thereby increased frictional traction on the basis that does not increase trailer coupling volume.
Description
Technical field
The utility model relates to a kind of trailer coupling.
Background technology
At nonwoven fabrics, weave cotton cloth, in the production process such as compound, the surface treatment of the coiled material such as paper, film, need carry out rolling operation.The trailer coupling of the speed that rolling effect completes and quality and its use is closely bound up.In prior art, trailer coupling mainly comprises the first driving wheel, the second driving wheel and driving band, and driving band is closed ring coated the first driving wheel, the second driving wheel simultaneously, can obtain: S according to Euler's formula
y=S
le
μ α, wherein, S
yfor frictional traction; α is that driving band encloses cornerite degree on driving wheel; S
lfor the tension force of driving band at driving wheel separation point; μ is the friction coefficient between driving band and driving wheel.As can be seen here, increase and to enclose wrap angle sigma and just can increase frictional traction.In prior art, thereby increase and enclose wrap angle sigma and reach the object that increases frictional traction by increasing the area of driving wheel or number.But this kind of mode increased cost, and increased the volume of whole trailer coupling.
Utility model content
Feature and advantage of the present utility model are partly statement in the following description, or can describe obviously from this, or can learn by putting into practice the utility model.
For overcoming the problem of prior art, the utility model provides a kind of trailer coupling, comprising: the first driving wheel, the second driving wheel and driving band; It is characterized in that, this driving band being wrapped on this first driving wheel and the second driving wheel is S-type, makes the direction of rotation of this first driving wheel and this second driving wheel.
Preferably, this first driving wheel is positioned at the top of this second driving wheel; Thereby this driving band forms this S type via the opposed area of this first driving wheel and the second driving wheel around to this first driving wheel upper limb from this second driving wheel lower edge.
Preferably, also comprise the first guide wheel and the second guide wheel, this driving band arrives this second driving wheel lower edge by this first guide wheel, and this driving band laid out and arrives the second guide wheel from this first driving wheel upper limb.
By reading specification sheets, those of ordinary skills will understand feature and the content of these technical schemes better.
Accompanying drawing explanation
Below by describing particularly the utility model with reference to accompanying drawing and in conjunction with example, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explaining to of the present utility model, and do not form the restriction of going up in all senses of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model embodiment trailer coupling.
The specific embodiment
As shown in Fig. 1 Fig. 3, the utility model provides a kind of trailer coupling, comprising: the first driving wheel 11, the second driving wheel 12 and driving band 30; It is characterized in that, the driving band 30 being wrapped on this first driving wheel 11 and the second driving wheel 12 is S-type, makes the direction of rotation of the first driving wheel 11 and the second driving wheel 12.So greatly increase driving band and enclosed cornerite degree on driving wheel, increased frictional traction.
In the present embodiment, the first driving wheel 11 is positioned at the top of the second driving wheel 12; Thereby driving band 30 forms this S type via the opposed area of the first driving wheel 11 and the second driving wheel 12 around to the upper limb of the first driving wheel 11 from the lower edge of this second driving wheel 12.Wherein the lower edge of the second driving wheel 12 comprises the nadir of the second driving wheel 12, and the upper limb of the first driving wheel 11 comprises the vertex of the first driving wheel 11.
In the present embodiment, this trailer coupling also comprises the first guide wheel 21 and the second guide wheel 22, and driving band 30 arrives the lower edge of the second driving wheel 12 by the first guide wheel 21, and this driving band 30 laid out arrival the second guide wheel 22 from the upper limb of the first driving wheel 11.
It should be noted that, when changing the rotation direction of power supplying apparatus (electrical motor, combustion engine etc.) or changing two driving wheels and guide wheel relative position, as long as it is S-type to meet the driving band 30 being wrapped on the first driving wheel 11 and the second driving wheel 12, the direction of rotation of the first driving wheel 11 and the second driving wheel 12 is just all belonged in field of application of the present utility model.
The trailer coupling that the utility model provides is by S-type by the driving band 30 being wrapped on this first driving wheel 11 and the second driving wheel 12, increase driving band and enclose cornerite degree on driving wheel, thereby increased frictional traction on the basis that does not increase trailer coupling volume.
With reference to the accompanying drawings of preferred embodiment of the present utility model, those skilled in the art do not depart from scope of the present utility model and essence above, can have multiple flexible program to realize the utility model.For example, the feature that illustrates or describe as the part of an embodiment can be used for another embodiment to obtain another embodiment.These are only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalence that all utilization the utility model specification sheetss and accompanying drawing content are done changes, within being all contained in interest field of the present utility model.
