Abstract
The utility model discloses a self-adjusting chain tightener, which comprises a support and a pressing block with an arc surface, wherein a plurality of mutually-parallel connecting rods are hinged between the support and the pressing block, and an elastic device which can translate the pressing block relative to the support arranged between the support and the pressing block; and an arc guiding bar arranged on the arc surface of the pressing block in a protruding way, wherein width of the arc guiding bar is equal to inner width of the inner link of a tightening chain. The self-adjusting chain tightener can adjust the tension of the chain without stopping the machine, which saves the adjusting time by stopping the machine and achieves automatic tension in the running process of the machine; and the chain is not easy to leave the normal track, thereby reducing failure rate and improving working efficiency.
Description
Technical field
The utility model relates to a kind of chain stretching device, especially relates to a kind of automatic regulating type chain stretching device that can adjust the chain tension degree automatically.
Background technique
At present, the chain tension on the combine-harvester adopts the mode of nylon roller or tension sprocket more, but these two kinds of chain tension modes can not reach auto-tensioning in the machinery operation process, can only manually regulate after shutdown; And in the process of work, because the continuous variation of chain bearing load, chain will be shaken, and owing to the nylon tension roller is not imposing restriction to the normal direction of chain at driving face because of it, so in growing apart from transmission the chain sideslip takes place very easily, the chain releasing phenomenon appears, and the surface of contact of common nylon tension roller and chain is all outer wide greater than the outer link of chain, in the tensioning process, tension roller also can rotate with it, and easily stay cut, damage the surface of tension roller, shorten the life-span of tension roller.And the tensioning mode of tension sprocket formula, because the manufacture cost of tension sprocket is than higher, and relatively stricter to the required precision of its installation, increased user cost accordingly.
Summary of the invention
Technical problem to be solved in the utility model has provided a kind ofly can shut down the automatic regulating type chain stretching device that just can regulate chain tension automatically; saved and shut down the time of adjusting; in machine operation procedure, just can reach auto-tensioning; and chain is difficult for taking place deviation phenomenon; reduce rate of fault, improved working efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: automatic regulating type chain stretching device, comprise bearing and the briquetting that is provided with the arcuation surface, being hinged between described bearing and the briquetting is connected to some connecting rods that are parallel to each other, and is provided with between described bearing and the briquetting to make the relative bearing of briquetting produce the elastic device of translation; Projection is provided with the identical arcuation sliver of inner width of width and institute's tension chain inner link on the arcuation surface of described briquetting.
As a kind of improvement, described connecting rod is to be positioned at the left and right sides of bearing and briquetting and respectively to have two.
As further improvement, be installed with support on the described briquetting, described connecting rod and support are hinged.
As further improvement, described elastic device is a spring.
The automatic regulating type chain stretching device of technique scheme, owing to be the briquetting that has adopted bearing and be provided with the arcuation surface, being hinged between bearing and the briquetting is connected to some connecting rods that are parallel to each other, and is provided with between bearing and the briquetting to make the relative bearing of briquetting produce the elastic device of translation; Projection is provided with the identical arcuation sliver of inner width of width and institute's tension chain inner link on the arcuation surface of briquetting, and chain contacts with the arcuation sliver on the arcuation surface of briquetting and slips over during work, can damaging surface, can improve working life; And under the elastic device effect, briquetting is to chain tension; Variation along with load; the tightness difference of chain, elastic device is corresponding to be adjusted automatically, and connecting rod also can promote briquetting and produce translation thus; the direction of translation is the tension direction of chain; in the whole work, the tensioning of chain need not manual operation, does not also need to shut down to adjust; like this in the operation of a machine process; just can be implemented in the auto-tensioning under the chain varying load state, simple and convenient, improved working efficiency greatly.And because the contact width of briquetting arcuation sliver and chain is the inner width of the inner link of chain, also limited the sideslip of chain transmission face, prevented the chain phenomenon; Connecting rod is to be positioned at bearing and briquetting each side two, all forms the simple structure of a four link type like this in every side.Be installed with support on briquetting, connecting rod and support are hinged, and the quadratic crank mechanism that forms by support, connecting rod, bearing promotes the briquetting flexible movements conveniently.Elastic device is spring, relies on spring action, makes briquetting automatically restore to suitable tension position, even occur owing to the external force effect under the situation of uneven load at chain, chain also can reach auto-tensioning.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the structural representation of the automatic regulating type chain stretching device of the utility model;
Fig. 2 be among Fig. 1 A-A to sectional view.
Embodiment
As shown in Figure 1 and Figure 2, automatic regulating type chain stretching device, comprise the bearing 5 that can be installed on the body, with the briquetting 1 that is provided with an arcuation surface, between bearing 5 and briquetting 1, be hinged and be connected to some connecting rods that are parallel to each other 3, can on briquetting 1, be installed with a support 2, and the mode that adopts connecting rod 3 and support 2 to be hinged, between bearing 5 and briquetting 1, be provided with elastic device 4, it serves as the axle swing with bearing 5 upper link points that elastic device 4 can make each connecting rod, thereby make briquetting 1 relative bearing 5 produce translation, be implemented in the auto-tensioning under the chain varying load state.Can be spring as elastic device 4, its two ends connect the mode of the hinged place of different connecting rods and bearing 5 and support 2 respectively.And projection is provided with the identical arcuation sliver 11 of inner width of width and institute's tension chain inner link on the arcuation surface of briquetting 1, to limit the sideslip of chain transmission face, prevents the chain phenomenon.And connecting rod adopts each side two the mode that is positioned at bearing 5 and briquetting 1, support 2, connecting rod, bearing 5 form the structure of a four link type like this, spring one end connects two connecting rods, one connecting rod that is arranged in homonymy, and other end is connected a connecting rod and support 2 hinged places with bearing 5 hinged places, under the effect of spring, promote the tension direction translation of briquetting 1 by this quadratic crank mechanism to chain, realize the tensioning of chain, flexible movements are convenient.
