Abstract
The utility model discloses a chain straining device for harvest machinery, constitute including sprocket A subassembly, chain, take -up pulley fixed plate, adjusting bolt, extension spring, tensioning wheel, sprocket B subassembly, bottom plate and lock nut. Sprocket A subassembly and sprocket B unit mount are on the take -up pulley fixed plate, the chain is installed on sprocket A subassembly and sprocket B subassembly, two tensioning wheel and take -up pulley bolted connection for the fixed plate, the adjusting bolt dress fastens with lock nut on the take -up pulley fixed plate, the extension spring both ends are installed at two adjusting bolt downtheholely respectively, and the take -up pulley fixed plate is fixed on the bottom plate with changeing axle bolt. Two -way tensioning chain is carried out to pretightning force through the adjustment extension spring. Under the pulling force of extension spring, sprocket A subassembly and sprocket B subassembly are when rotating to and the chain break -in is after elongated, CD chain limit and AB chain limit can be simultaneously can the centering tensioning, can remain effective tensioning of chain in addition throughout, and avoid the sprocket to fall the emergence of tooth and jump tooth phenomenon.
Description
Technical field
This utility model relates to a kind of harvest machinery chain tensioning mechanism, belongs to universal machine field.
Background technology
At present, the chain tension mode simple regulating wheel of many employings common on market compresses chain by regulating wheel pretightning force, this mode needs artificial periodic adjustment could realize effective tensioning of chain after chain break-in is elongated, additionally also has a kind of auto-tensioning mode, but artificial change regulating wheel position ability re-tensioning chain, operation inconvenience is needed when sprocket wheel inverts.
Chinese patent literature CN201351717Y discloses one " chain Radspanner ", although being also two-way tensioning, but this structure is only applicable to automobile, bicycle, kart etc., and the stage clip tensioning used, and two regulating wheel must on the same axis, on harvest machinery and inapplicable.
Chinese patent literature CN2859091Y discloses one " chain Radspanner ", although be also two-way tensioning, but this structure but structure are ground with chain all the time mutually because of briquetting, easily wear and tear, and needs periodic replacement, causes the increase of cost from face.
In order to solve the problems referred to above, a kind of harvest machinery chain tensioning mechanism of special invention.
Summary of the invention
The technical problems to be solved in the utility model: for because of chain break-in elongated after, need artificial periodic adjustment could realize the effective tensioning of chain, and can not effectively tensioning when sprocket wheel antiport, and slack list need to artificially change regulating wheel position and could realize effective tensioning, it is the most inconvenient to operate, solve the problem that sprocket wheel reaches coplanar simultaneously, devise a kind of new-type automatic chain tensioning mode for this.
This utility model one harvest machinery chain tensioning mechanism, the technical scheme used: 1, sprocket wheel A assembly, 2, chain, 3, regulating wheel fixed plate, 4, regulation bolt, 5, extension spring, 6, tensioning wheel assembly, 7, sprocket wheel B assembly, 8, base plate, 9, locking nut.Sprocket wheel A assembly and sprocket wheel B assembly are fixed in regulating wheel fixed plate；Chain is arranged on sprocket wheel A assembly and sprocket wheel B assembly；Two tensioning wheel assemblies and regulating wheel fixed plate are bolted in regulating wheel fixed plate；Regulation bolt is contained in regulating wheel fixed plate, fastens with locking nut；Extension spring two ends are separately mounted in two regulation bolts hole.Two-way tension chain is carried out to the certain pretightning force of chain applying by adjusting the nut of regulation bolt.Under the pulling force of extension spring, sprocket wheel A assembly and sprocket wheel B assembly are when rotating, and Hui Xiang center tensioning simultaneously is understood on CD chain limit and AB chain limit, and is the effective tensioning that can remain chain, and avoid sprocket wheel to fall tooth and slippage phenomenon generation.
Adopting the structure can be when chain break-in be elongated, effective tensioning of chain can be remained under the effect of extension spring, and utilize the adjustment of regulation bolt, the pulling force that spring holding is certain can be made, remain able to when sprocket wheel antiport on the premise of need not artificially changing regulating wheel tension position still can effectively tensioning, the sprocket wheel in sprocket wheel A assembly, sprocket wheel B assembly and tensioning wheel assembly the most also can be made to reach coplanar, rational in infrastructure, transmission is relatively reliable, more convenient to operate.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and detailed description of the invention the present invention is described in more detail.
Fig. 1 is a kind of harvest machinery chain tensioning mechanism structural representation；
Fig. 2 is the schematic diagram that tensioning wheel assembly is arranged in regulating wheel fixed plate；
Fig. 3 is that regulation bolt is arranged on the schematic diagram in regulating wheel fixed plate.
In figure: 1, sprocket wheel A assembly 2, chain 3, regulating wheel fixed plate 4, regulation bolt 5, extension spring 6, tensioning wheel assembly 7, sprocket wheel B assembly 8, base plate 9, locking nut.
Detailed description of the invention
About detailed description and the technology contents of utility model, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides reference and purposes of discussion, be not used for the present invention is any limitation as.
First have to adjust by adjusting regulation bolt the pulling force of extension spring, apply certain pretightning force to chain simultaneously and carry out two-way tension chain.Under the pulling force of extension spring, when sprocket wheel A assembly 1 rotates clockwise as drivewheel, band movable sprocket B assembly 7 rotates clockwise, CD limit is the pilled-in selvedge Hui Xiang center tensioning of chain 2, tensioning wheel assembly 6 can rotate centered by O1, and then drive extension spring 5 and another set tensioning wheel assembly 6 to rotate centered by O2 thus remain effective tensioning of chain.And when sprocket wheel antiport, i.e. sprocket wheel A assembly 1 rotarily drives sprocket wheel B assembly 7 counterclockwise and rotates counterclockwise, at this moment AB chain Bian Shi pilled-in selvedge alliance Yang Huixiang center tensioning, tensioning wheel assembly 6 can rotate under chain 2 tensile force effect centered by O2, and then drive extension spring 5 and another set tensioning wheel assembly 6 to rotate centered by O1 thus remain effective tensioning of chain 2.And effective tensioning of chain can be remained, and sprocket wheel is avoided to fall tooth and slippage phenomenon generation.Additionally after chain break-in is elongated, the effect lower chain at tension spring tension equally still can realize effective tensioning.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence change of patent spirit of the present utility model, all should all belong to the scope of the claims of the present utility model.
