Abstract
The utility model discloses a kind of machinery belt transmission automatic takeup, comprise driving shaft, driven shaft, frame I, frame II, also comprise elastic element, described frame I is flexibly connected with frame II, described driven shaft is connected with frame II by linkage mechanism, described elastic element is fixedly connected with frame I, and driving shaft is rotatably connected with elastic element.When the load of driven shaft is excessive; make frame II and frame I can not relative movement time or mobile range when not reaching predetermined stroke; now be connected the effect that elastic element just serves adjustment two wheelbase with driving shaft; the belt of two between centers is got loose; driving shaft is in idling conditions, effectively protects power source and whole mechanism.
Description
Technical field
The utility model relates to a kind of power transmitting mechanism, is particularly applied to bel-drivenn device.
Background technique
In traditional belt drive unit, all comprise driving shaft and driven shaft, power is delivered to driven shaft from driving shaft by belt, and then exports via driven shaft.In order to make kinetic force transmit smoothly, the belt of two between centers generally all can be made to be in tensioned state, and in order to power stablizing in course of conveying, the distance of two between centers is changeless.And relatively-stationary diaxon not only makes troubles to belt installation, and when the overload of output terminal time, reaction force may make motor be burned.Especially for the mechanism of some closed installations, the difficulty of maintenance and cost will be very high.
Model utility content
The technical problems to be solved in the utility model is: the belt drive unit providing a kind of energy automatic pressure-relieving.
The solution that the utility model solves its technical problem is: a kind of machinery belt transmission automatic takeup, comprise driving shaft, driven shaft, frame I, frame II, also comprise elastic element, described frame I is flexibly connected with frame II, described driven shaft is connected with frame II by linkage mechanism, described elastic element is fixedly connected with frame I, and driving shaft is rotatably connected with elastic element.
As the further improvement of technique scheme, also comprise belt, driving wheel, follower, slide mechanism, described driving wheel is fixedly connected with driving shaft, and described follower is fixedly connected with driven shaft, and described belt is connected with driving wheel, follower; Described frame II is connected with frame I by slide mechanism, and frame II can be moved left and right by frame I relatively.
As the further improvement of technique scheme, described elastic element is helical spring.
As the further improvement of technique scheme, also comprise pedestal, described driving shaft is rotatably connected with pedestal, and described helical spring has many, and described all helical spring one end are fixedly connected with other one end and are fixedly connected with pedestal with frame I.
The beneficial effects of the utility model are: under normal operation; driven shaft and then drive chassis II is driven to carry out relative movement with frame I by driving shaft; in moving process; the wheelbase of diaxon remains unchanged; but when the load of driven shaft is excessive; make frame II and frame I can not relative movement time or mobile range when not reaching predetermined stroke; now be connected the effect that elastic element just serves adjustment two wheelbase with driving shaft; the belt of two between centers is got loose; driving shaft is in idling conditions, effectively protects power source and whole mechanism.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, instead of whole embodiment, and those skilled in the art, under the prerequisite not paying creative work, can also obtain other design proposals and accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.In addition, all connection/annexations mentioned in literary composition, not singly refer to that component directly connects, and refer to and according to concrete performance, can connect auxiliary by adding or reducing, and form more excellent connecting structure.Each technical characteristics in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
With reference to Fig. 1, a kind of machinery belt transmission automatic takeup, comprise driving shaft 1, driven shaft 2, frame I41, frame II42, also comprise belt 3, driving wheel 11, follower 21, slide mechanism, elastic element 5, described driving wheel 11 is fixedly connected with driving shaft 1, described follower 21 is fixedly connected with driven shaft 2, and described belt 3 is connected with driving wheel 11, follower 21; Described frame II42 is connected with frame I41 by slide mechanism, and frame II42 can be moved left and right by frame I41 relatively; Described frame I41 is flexibly connected with frame II42, and described driven shaft 2 is connected with frame II42 by linkage mechanism, and described elastic element 5 is fixedly connected with frame I41, and driving shaft 1 is rotatably connected with elastic element 5.
Operation, power is sent to driving shaft by power source, driving shaft rotates by driving driving wheel, then driving wheel drives follower to rotate under the effect of belt, then follower drives driven shaft to rotate, and last driven shaft is slided by the relative frame I of bar linkage structure (not looking in figure) drive chassis II; When frame II load is excessive, driven shaft is difficult to rotate, and now reaction force is delivered to driving shaft, and is connected with frame I by elastic element due to driving shaft, the reaction force of this part can be absorbed by elastic element, elastic element generation deformation, now makes the distance of two between centers there occurs change, and then makes originally to be in that the belt tightened becomes is lax, driving wheel and follower depart from, driving wheel dallies, and avoids reaction force and passes back to power source always, damage equipment.And along with length of side service time of belt, belt also can become lax, now utilizes the automatic corrective action of elastic element, adjusts the spacing of two between centers, make belt again tighten; Extend the real working life of integrated model.
Be further used as preferred embodiment, described elastic element 5 is helical spring.
Be further used as preferred embodiment, also comprise pedestal, described driving shaft 1 is rotatably connected with pedestal, and described helical spring has many, and described all helical spring one end are fixedly connected with other one end and are fixedly connected with pedestal with frame I41.
Above better embodiment of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
