Abstract
The utility model discloses a sprocket tension device of a chain transmission mechanism, which is characterized in that the sprocket tension device of the chain transmission mechanism comprises a slider, a slide rail and a power oil cylinder, wherein the slider is fixedly connected with a sprocket, the slide rail is used to slide the slider, a piston rod of the power oil cylinder can support and hole the slider, and the bottom portion of the slider is connected with a one-way moving lock device. The sprocket tension device of the chain transmission mechanism overcomes the problem that a chainneeds to be dismantled when a drive chain in a prior chain transmission mechanism looses and adjusts, the sprocket tension device achieves to tension the chain after loosing through adjusting the distance between a drive sprocket and a driven sprocket, the drive chain does not need to be dismantled, and the sprocket tension device of the chain transmission mechanism has the characteristics of simple operation, rapid speed, health and no pollution.
Description
Technical field
The utility model relates to the sprocket wheel tension device of the sprocket wheel of chain drive, particularly a kind of chain drive.
Background technique
Chain drive is widely used in the middle of life and the production, the drive chain composition that it generally comprises drive sprocket, driven sprocket and is connected both.In the middle of reality was used, because of the existence of flow of metal, chain drive was after long-play, and loosening phenomenon will take place drive chain, if untimely the adjustment will be caused the weak or chain releasing phenomenon of transmission.At present, because of all fixing the position of drive sprocket and driven sprocket, promptly distance between the two is changeless, this makes the adjustment means that can take only unload lower chain, shorten the purpose that chain length reaches tension chain by removing the chain unit piece, whole adjustment process not only troublesome poeration, efficient is low, also can pollute both hands simultaneously, causes lubricant oil to run off.
The model utility content
At the problems referred to above, the utility model provides a kind of sprocket wheel tension device of chain drive, this mechanism realizes the adjustment of tensioning again that chain is loosening by the adjustment to drive sprocket and driven chain tyre tread, have simple to operate, speed is fast, the free of contamination characteristics of health.
For achieving the above object, the utility model is by the following technical solutions:
A kind of sprocket wheel tension device of chain drive is characterized in that: the power cylinder that comprise the slide block that is fixed together with a sprocket wheel, be used for slide rail that slide block slides, piston rod can hold mutually with slide block; Described slider bottom is connected with unidirectional moving locking device.
Above-mentioned sprocket wheel is the drive sprocket or the driven sprocket of chain drive.
Above-mentioned unidirectional moving locking device comprises locking chain and single direction ratchet, wherein locks chain and slide block is fixed together.
In case the chain of chain drive takes place loosening, just can start oil cylinder, promoting slide block by piston rod moves along slide rail, thereby make the sprocket wheel that is fixed together with slide block, the locking chain moves synchronously, at this, the mobile active that makes chain drive of sprocket wheel, the distance of driven two sprocket wheels widens, make drive chain tensioning gradually, and the locking chain is mobile, the single direction ratchet that drives unidirectional moving locking device is rotated, this process lasts till drive chain once more till the tensioning always, and subsequently, the oil cylinder piston bar is got back to initial position, and the reverse stop of single direction ratchet, slide block, sprocket wheel stop under the interaction of locking chain and drive chain tension force, the tensioning adjustment of drive chain is finished in the location of realizing reposition.
In sum, the utility model is realized the adjustment of tensioning again that chain is loosening by the adjustment to drive sprocket and driven chain tyre tread, need not to carry out the dismounting of drive chain, have simple to operate, speed is fast, the free of contamination characteristics of health.
At this, the sprocket wheel that is connected with slide block can be the drive sprocket of chain drive, also can make driven sprocket, and it is set according to actual needs.
Description of drawings
Fig. 1, perspective view of the present utility model;
Fig. 2, perspective view of the present utility model two.
Embodiment
As illustrated in fig. 1 and 2, a kind of sprocket wheel tension device of chain drive, the power cylinder 3 that comprise a slide block 1, be used for slide rail 2 that slide block slides, piston rod 31 can hold mutually with slide block 1.
Wherein slide block 1 is fixed together with the sprocket wheel 4 of chain drive, specifically is drive sprocket or driven sprocket sprocket wheel at this sprocket wheel 4, sets according to actual needs.Described slide block 1 bottom is connected with unidirectional moving locking device 5, and in the present embodiment, unidirectional moving locking device comprises 5 locking chain 51 and single direction ratchet 52, wherein locks chain 51 and is fixed together with slide block 1.
In use, in case the drive chain of chain drive (non-key points in design, do not look among the figure) take place to become flexible, just can start oil cylinder 3, promoting slide block 1 by piston rod 31 moves along slide rail 2, thereby make the sprocket wheel 4 that is fixed together with slide block 1, locking chain 51 same moved further, at this, the mobile active that makes chain drive of sprocket wheel 4, the distance of driven two sprocket wheels widens, and makes drive chain tensioning gradually, and locking chain 51 is mobile, the single direction ratchet 52 that drives unidirectional moving locking device 5 is rotated, this process lasts till drive chain once more till the tensioning always, and subsequently, oil cylinder piston bar 31 is got back to initial position, and single direction ratchet 52 reverse stop, slide block 1, sprocket wheel 4 stop under the interaction of locking chain 51 and drive chain tension force, the tensioning adjustment of drive chain is finished in the location of realizing reposition.
In sum, the utility model is by the adjustment to drive sprocket and driven chain tyre tread Realize the again tensioning adjustment of chain-loose, need not to carry out the dismounting of driving chain, have operation Simply, fast, the free of contamination characteristics of health of speed.
Claims (3)
1, a kind of sprocket wheel tension device of chain drive is characterized in that: the power cylinder that comprise the slide block that is fixed together with a sprocket wheel, be used for slide rail that slide block slides, piston rod can hold mutually with slide block; Described slider bottom is connected with unidirectional moving locking device.
2, the sprocket wheel tension device of a kind of chain drive as claimed in claim 1 is characterized in that: described sprocket wheel is the drive sprocket or the driven sprocket of chain drive.
3, the sprocket wheel tension device of a kind of chain drive as claimed in claim 1 is characterized in that: described unidirectional moving locking device comprises locking chain and single direction ratchet, wherein locks chain and slide block is fixed together.
