Accompanying drawing explanation
By the detailed description of the invention part provided referring to the drawings, this be will be more readily understood
The feature and advantage of utility model, in the accompanying drawings:
Fig. 1 is the side view according to tensioner of the present utility model.
Fig. 2 is the sectional view according to the A-A along the line of tensioner as shown in Figure 1 of the present utility model.
Detailed description of the invention
With reference to the accompanying drawings illustrative embodiments of the present utility model is described in detail.To showing
The description of example embodiment is merely for the sake of demonstration purpose, and is definitely not this utility model and answers
With or the restriction of usage.
The utility model proposes a kind of tensioner 10, this tensioner 10 include tension pulley support 12,
The sleeve pipe 16 that is arranged on tension pulley support 12 by bolt 14 and be rotatably disposed at sleeve pipe 16
On regulating wheel 18, as depicted in figs. 1 and 2.The side plate of tension pulley support 12 is provided with through hole,
Bolt 14 is located in through hole, and through the endoporus of sleeve pipe 16, by being arranged on the end of bolt 14
The nut 142 in portion makes sleeve pipe 16 be connected with being relatively fixed with tension pulley support 12.Regulating wheel 18 is permissible
It is rotatably disposed on the periphery of sleeve pipe 16 by bearing 182.After regulating wheel 18 setting is put in place,
Can by need the belt of tensioning or chain around the home in the outside of regulating wheel 18, thus to belt or chain
Play tension.
Further, also include being arranged on tension pulley support 12 according to tensioner 10 of the present utility model
And the tensioning reinforcing plate 20 between sleeve pipe 16.Tensioning reinforcing plate 20 can provide tension pulley support 12 with
The frictional force of the increase between sleeve pipe 16, so that sleeve pipe 16 can be arranged in more firm mode
On tension pulley support 12.
In order to improve the frictional force between sleeve pipe 16 and tension pulley support 12 further and thus make sleeve pipe
16 are more securely disposed at tension pulley support 12 during the use of tensioner 10, add in tensioning
It is provided with the first friction structure on the surface contacted with tension pulley support 12 of strong plate 20.Rub by first
Wipe structure and the frictional force of the increase between tensioning reinforcing plate 20 and tension pulley support 12 can be provided, and then
There is provided the sleeve pipe 16 frictional force relative to the increase of tension pulley support 12 so that sleeve pipe 16 can be relative
Arrange more securely in tension pulley support 12.Advantageously, the first friction structure can be the first dentation
Structure 202.It is of course also possible to use the other kinds of structure improving frictional force, such as tensioning is added
The surface configuration contacted with tension pulley support 12 of strong plate 20 becomes the form of little concaveconvex structure.
It is likewise possible to be provided with on the surface contacted with tensioning reinforcing plate 20 of tension pulley support 12
Second friction structure.Tensioning reinforcing plate 20 and tension pulley support 12 can be provided by the second friction structure
Between the frictional force increased further, and then provide sleeve pipe 16 to enter one relative to tension pulley support 12
The frictional force that step increases so that sleeve pipe 16 can be arranged more securely relative to tension pulley support 12.
Advantageously, the second friction structure can be the second dentalation 122.It is of course also possible to use raising to rub
The other kinds of structure of wiping power, such as by the table contacted with tensioning reinforcing plate 20 of tension pulley support 12
Face is arranged to the form of little concaveconvex structure.It can be advantageous to strengthen at tension pulley support 12 and tensioning
Frictional force that is identical and that can be engaged with each other is set on the surface contacted with each other of plate 20 and increases structure.
During the use according to tensioner 10 of the present utility model, when regulating wheel 18 is tensioned to need
During the tension position wanted, on the first dentalation 202 of tensioning reinforcing plate 20 and tension pulley support 12
Second dentalation 122 engages each other together, and this structure utilizes the feature of dentalation to increase set
Friction area between pipe 16 and tension pulley support 12, thereby increases regulating wheel 18 relative to tensioning
The friction area of wheel support 12, therefore adds frictional force.Dentalation itself also is able to offset one
Say good-bye clamp force so that regulating wheel 18 can bear bigger tensile force, greatly strengthen making of regulating wheel 18
With life-span and tension so that the drive mechanism using this tensioner 10 is more firm, transmission
Reliability is higher.
In farm machinery, using V belt translation or chaindriven drive mechanism more, therefore, this practicality is new
Type also protects the agricultural machinery using tensioner 10 as above, advantageously, this agricultural machinery
For combined harvester.Similarly use the combined harvester according to tensioner 10 of the present utility model also
There is advantage as above, i.e. can be greatly improved V belt translation or chaindriven by tensioner 10
Transmission efficiency, and this tensioner 10 will not deform or displacement in long use process,
So that tensioner 10 can be transmission band or the transmission of combined harvester within considerable time
Chain provides satisfactory tension, and without tensioner 10 being adjusted frequently or tieing up
Protect.Therefore, the working performance energy of the combined harvester according to tensioner 10 of the present utility model is used
Enough greatly improve.
Although this utility model being described with reference to illustrative embodiments, but it is to be understood that
This utility model is not limited in literary composition the detailed description of the invention describing in detail and illustrating, without departing from
In the case of claims limited range, those skilled in the art can be to described exemplary
Embodiment makes various improvement or modification.
