Specific embodiment
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, attached drawing will be compareed below
Illustrate specific embodiment of the present utility model.It should be evident that the accompanying drawings in the following description is only the one of the utility model
A little embodiments for those of ordinary skill in the art without creative efforts, can also be according to these
Attached drawing obtains other embodiments.
In the embodiment one of utility model, referring to shown in Fig. 1-3, a kind of transmission for corn harvester header commutates
Device is mainly arranged between the rack of corn picker and the ceding of Taiwan, and specific includes an input sprocket 1 and an output chain
Wheel 2, wherein input sprocket 1 connects a power device, and output chain gear 2 is arranged in the ceding of Taiwan, while input sprocket 1 and output chain
Wheel 2 is attached by a chain 3, to realize power transmission.
In actual use, further further include a pair of tightener sprocket for being used for tension chain 3, and a pair is tensioned chain
It takes turns and is attached with input sprocket 1 by being socketed in the chain 3 in outside, and output chain gear 2 is located at the outside of chain 3, and and chain
Item 3 is connected.The positional relationship for passing through output chain gear 2 and chain 3 in this way makes it through when chain 3 is driven and inputs chain
Wheel 1 is contrary with output chain gear 2, simultaneously because long-time conveyor chain 3 can loosen, so by being set in chain
A pair of of tightener sprocket in 3 carries out tensioning adjustment to it, and design is simple ingenious.
Shown referring to Fig. 3 in the present embodiment one, the output chain gear 2 being provided with is mounted on by an output shaft 21 and is cut
On platform, while output shaft 21 being arranged to certain length.Purpose is further to also set up a tensioner arm 5, will be tensioned
The both ends of arm 5 are attached with a pair of of tightener sprocket, and the axle center of tensioner arm 5 is set in the outside of output shaft 21, makes its structure
It is more compact.It should be noted that in actual use, a pair of of tightener sprocket includes the first tightener sprocket 41 and the second tightener sprocket
42, the both ends of tensioner arm 5 are attached with the first tightener sprocket 41 and the second tightener sprocket 42 respectively in this way, it is therefore an objective to
So that two tightener sprockets set up separately and realize in the two sides of output chain gear 2 and be tensioned simultaneously to the chain 3 of two sides, avoid it is elastic not
One influences using effect.
In the present embodiment one, a fixed frame 6 is further also set up between tensioner arm 5 and the outer wall of output shaft 21,
Fixed frame 6 is mainly used for fixed tensioner arm 5, while tensioner arm 5 being avoided directly to contact with output shaft 21, to influence to export chain
The rotation of wheel 2.So one end of fixed frame 6 is attached with the ceding of Taiwan, and the other end is set on output shaft 21, and with output
There are certain intervals between the outer surface of axis 21.While support to achieve to tensioner arm 5, moreover it is possible to avoid tensioning wall
Rotation affects to output shaft 21.It is ingenious in design reasonable.
In the present embodiment two, referring again to shown in 3, improve on the basis of the above embodiments, and improvements
It is: a bearing shell 7 will be further set between tensioner arm 5 and fixed frame 6, it is therefore an objective to reduce between tensioner arm 5 and fixed frame 6
Frictional force, improve the smoothness of rotation, avoid between the two frictional force it is excessive and cause mutual abrasion, effectively prolong
Long life.Tensioner arm 5 is arranged to carry out 180 ° of rotation simultaneously, the purpose of this setting is to improve to open around fixed frame 6
The tensioning range of tight sprocket wheel.Wherein it should be noted that contact area between the size of bearing shell 7 and tensioner arm 5 and fixed frame 6 and
It is fixed, it is only necessary to be paved with contact area between the two.
It is further on the basis of above-mentioned two embodiment to be improved in the present embodiment three, and the improvement is that:
There are many modes for adjusting tensioner arm 5, further to be arranged a tensioning spring 8 in the present embodiment, while by tensioning spring 8
One end and one end of tensioner arm 5 are attached, and the other end is attached by one rack of an adjusting screw rod, as shown in Figure 1.This
Sample pulls tensioner arm 5 by tensioning spring 8 after adjusting adjusting screw rod 9, when specifically used to pull tightener sprocket
It is rotated, realizes the tensioning to chain 3.
In above three embodiments, it should be noted that power device is engine, there is engine to provide power in this way, drive
Input sprocket 1 is rotated clockwise or counterclockwise, then drives output chain gear 2 to do rotation in contrast by chain 3.Work as length
Chain 3 loosens when time is driven, and at this moment tensioner arm 5 is adjusted by adjusting adjusting screw rod 9, to utilize tightener sprocket pair
Chain 3 is tensioned, and so that it is entirely driven reversing arrangement continuation and is smoothly worked.
It should be noted that above-described embodiment can be freely combined as needed.The above is only the utility model
Preferred embodiment, it is noted that for those skilled in the art, do not departing from the utility model principle
Under the premise of, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the protection scope of the utility model.
