Specific implementation mode
Below in conjunction with the utility model embodiment attached drawing, the technical scheme in the embodiment of the utility model is carried out clear
It removes, be fully described by, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole realities
Apply example.Based on the embodiments of the present invention, those skilled in the art are obtained without making creative work
The other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, be one preferred embodiment of the utility model, the embodiment provide a kind of transmission belt of transmission system from
Dynamic tensioning apparatus, wherein transmission system include transmission belt 4, and transmission belt automatic tightener includes tensioner 3, elastic component 1, installation
Frame and the swing component 2 on the mounting bracket；Elastic component 1 connects swing component 2, to adjust the amplitude of fluctuation of swing component 2；It swings
Part 2 connects tensioner 3, to adjust the position of tensioner 3 according to the slackness of transmission belt 4；Tensioner 3 connects transmission belt 4, uses
To compress transmission belt 4 so that transmission belt 4 is in tensioning state.
Specifically, elastic component 1 connects swing component 2, and the elasticity tension of elastic component 1 directly acts on swing component 2；Swing component 2
One end be fixed on mounting bracket, the other end connects tensioner 3；Tensioner 3 is in direct contact with transmission belt 4, when pine occurs in transmission belt 4
When relaxation phenomenon, under the action of the elasticity tension of elastic component 1, swing component 2 is moved along the direction of elasticity tension, tensioner 3 to
The direction of transmission belt 4 is moved, until transmission belt 4 is tightened.It should be noted that if transmission belt 4 is in over-tension state,
Mobile object is transmitted on transmission belt 4 and just will appear wild effects such as " playing bullet ", is unfavorable for being smoothed out for transmission process；It wants
Avoid above-mentioned phenomenon, elastic component 1 or/and transmission belt 4 should have certain spring-back effect, and spring-back effect depend on elastic component 1,
The performance of the material of transmission belt 4 itself.
In the present embodiment, swing component 2 is double yokes, which includes a fixed arm 21 and a lever arm 22；It is fixed
Arm 21 is fixed on mounting bracket；One end of lever arm 22 is connected and fixed arm 21, and the other end of lever arm 22 connects tensioner 3.
Specifically, lever arm 22 can also can be jointly socketed on a certain component with fixed arm 21 by articulated connection,
As long as realizing that lever arm 22 can be swingable at once relative to the connection end point；In practical application, lever arm 22 and fixed arm 21 it
Between constitute a link mechanism, lever arm 22 does not require dimensionally symmetrically with fixed arm 21, and lever arm 22 is as movable part
Part, length can be slightly long relative to fixed arm 22, in favor of improving the sphere of action of lever arm 22, enhancing tensioner 3 and transmission
With the relative motion amplitude between 4.
In the present embodiment, lever arm 22 is made of strip boards.
Specifically, lever arm 22 is effectively equivalent to one that length-width ratio is more than 1 in shape without any restrictions
" pole "；In view of the processability of lever arm 22,22 preferred column of lever arm or square shape or similar to column or the structure of square shape；
Lever arm 22 can be hollow can also be it is solid, but lightweight be often conducive to reduce power consumption and improve it is movable flexibly
Degree, therefore, preferred hollow-core construction；Lever arm 22 can be real for lightweight and economy by preparations such as bamboo wood, timber, metal and alloys
It considers, lever arm 22 is preferably made of bamboo wood or timber；In conjunction with above-mentioned each factor, and the portion needed for Layout processing on plank
Part is relatively convenient, and lever arm 22 is made of strip boards in the present embodiment.
In the present embodiment, elastic component 1 is torsional spring, and one end of torsional spring is connected and fixed arm 21, and the other end connection of torsional spring is lived
Swing arm 22.
Specifically, torsional spring is mounted on swing component 2, directly controls the movement of lever arm 22；The effect of torsional spring is by right
Lever arm 22 applies outside tension and tensioner 3 is made to compress belt always；Torsional spring itself has certain pre- deformation angle, no
The pre- deformation angle of same specification or the torsional spring of different model is different, when selecting torsional spring, needs first to determine turning for lever arm 22
Dynamic angle；In order to enable tensioner 3 to compress transmission belt 4, the rotational angle of lever arm 22 needs to be less than the pre- deformation angle of torsional spring；
In addition, 1 long-time of elastic component is in deformed state, service life is relatively low, and the frequency for replacing failure elastic component 1 is also high,
Select torsional spring as elastic component 1, one of reason is that installation torsional spring is easier here.
In the present embodiment, tensioner 3 is circular belt pulley or sprocket wheel.
It should be noted that circular belt pulley or sprocket wheel are mostly standard components, selectivity is larger, when needing replacing
It is more convenient.
In another optional embodiment, tensioner 3 is elliptic wheel, and the long axis of the elliptic wheel is parallel with transmission belt 4.
Specifically, since lever arm 22 drives the movement of tensioner 3 to be happened on the direction for being parallel to transmission belt 4, in conjunction with
Fig. 2, when relaxation occurs in transmission belt 4, tensioner 3 can be directly perpendicular to the movement of transmission belt 4, itself can also occur to turn
It moves, or vertical movement and own rotation occur simultaneously；When tensioner 3 is that long axis is parallel to the elliptic wheel of transmission belt 4,
Tight 3 rotation of of part itself can tighten transmission belt 4.
In the present embodiment, transmission belt automatic tightener further includes the rotatable shaft on mounting bracket, and shaft connects
Swing component 2 and tensioner 3 are connect, swing component 2 drives pivot, shaft that tensioner 3 is driven to move.
As shown in Fig. 2, being one preferred embodiment of the utility model, which provides a kind of transmission system, the power train
System includes the transmission belt automatic tightener of transmission belt 4, straining pulley 5, driving device and any of the above-described, transmission belt 4, straining pulley
5 and driving device be set on mounting bracket, straining pulley 5 and transmission belt automatic tightener are respectively arranged on the two opposite sides of transmission belt 4
On face, driving device is driving straining pulley 5 and transmission belt 4 to move.
In the present embodiment, the quantity of straining pulley 5 is at least one.
It should be noted that when the quantity of straining pulley 5 is only one, one end of transmission belt 4 is placed on straining pulley 5, another
End is connected to remaining rotatable components；Straining pulley 5 uses generally in the form of wheel group, including a driving wheel and a driven wheel.
In the present embodiment, transmission belt 4 is belt or chain.
To sum up, a kind of transmission belt automatic tightener of transmission system includes tensioner, elastic component, mounting bracket and is set to this
Swing component on mounting bracket；Elastic component connects swing component, to adjust the amplitude of fluctuation of swing component；Swing component connects tensioner,
To adjust the position of tensioner according to the slackness of transmission belt；Tensioner connects transmission belt, to compress transmission belt so that passes
