Abstract
The utility model discloses a drive chain tension adjusting device, it is including at least two gears and drive chain, the gear passes through the drive chain transmission and connects, the last overspeed device tensioner that installs of drive chain, overspeed device tensioner is including studdle, support frame and tensioning frame, studdle one end plug bush is on the support frame, and it is fixed to pass through the nut spiro union, the studdle other end is fixed with tensioning frame, tensioning frame puts on the shelf and is equipped with the spacing running roller that the bisymmetry set up, drive chain passes from between the wheel face of two spacing running rollers. The utility model discloses set up overspeed device tensioner on drive chain, overspeed device tensioner to the effect that drive chain played the support, just do not influence the transmission of chain, and the fixed position of studdle on the support frame is adjusted to the accessible including setting up the rotatable spacing running roller in the drive chain both sides to make spacing running roller play the effect that the tensioning was adjusted to drive chain, simple structure guarantees the high -efficient operation of drive chain.
Description
Technical field:
This utility model relates to conveying equipment technical field, particularly to a kind of driving chain tension-adjusting gear.
Background technology:
Driving chain makes to rotate under the drive of gear and motor to transmit, owing to the power output shaft of motor, chain, gear are all to be made by rigid material, chain is the most loose easily to come off, if chain is too tight, after work a period of time, chain is easily deformed and even ruptures, gear and motor also can be produced certain infringement, it is, thus, sought for a kind of rate of tension that can conveniently regulate chain, chain is made to keep the device of good tensioning state.
Utility model content:
This utility model provides a kind of driving chain tension-adjusting gear, solves the problem that pine crossed by driving chain in prior art or tension is difficult to regulation.
Technology solution of the present utility model is as follows: a kind of driving chain tension-adjusting gear, it includes at least two gear and driving chain, described gear is in transmission connection by driving chain, on described driving chain, tensioner is installed, described tensioner includes studdle, bracing frame and tensioning frame, described studdle one end sleeve is on bracing frame, and it is fixing to be spirally connected by nut, the described studdle other end is fixed with tensioning frame, described tensioning frame is added is provided with two symmetrically arranged spacing running rollers, described driving chain passes between the wheel face of two spacing running rollers.
As preferably, the direction of axis line of spacing running roller described in two is parallel with the direction of axis line of the bearing pin on driving chain.The transmission direction of the most spacing running roller passes parallel with the transmission direction of driving chain, thus does not affect the transmission of chain.
As preferably, the wheel face of spacing running roller described in two all forms the stopper slot matched with driving chain.In so driving chain caters to the stopper slot on two spacing running roller wheel faces, it is not easy to abjection.
As preferably, described in two, spacing running roller is arranged on tensioning frame by rotating shaft and bearing.The frictional force that driving chain is produced by the most spacing running roller is less, thus does not affect the transmission of chain.
As preferably, described nut includes two, and it lays respectively at the both sides of studdle and the sleeve hole of bracing frame.So by regulating two nuts position on studdle, thus can regulate the spacing between bracing frame and tensioning frame, thus regulate the tensile force of driving chain, two nuts make the fixing more firm of studdle, easy to adjust.
The beneficial effects of the utility model are: arrange tensioner on driving chain, tensioner includes the rotating spacing running roller being arranged on driving chain both sides, driving chain is played the effect of support, and do not affect the transmission of chain, and can be by adjusting studdle fixed position on bracing frame, so that driving chain is played the effect of tensioning regulation, simple in construction, it is ensured that driving chain Effec-tive Function by spacing running roller.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1, gear；2, driving chain；3, studdle；4, bracing frame；5, tensioning frame；6, nut；7, spacing running roller；8, stopper slot.
Detailed description of the invention:
In conjunction with accompanying drawing 1 to this utility model one driving chain tension-adjusting gear, it is described further.
A kind of driving chain tension-adjusting gear of the present utility model, it includes at least two gear 1 and driving chain 2, gear 1 is in transmission connection by driving chain 2, on driving chain 2, tensioner is installed, tensioner includes studdle 3, bracing frame 4 and tensioning frame 5, studdle 3 one end sleeve is on bracing frame 4, and it is spirally connected fixing by nut 6, studdle 3 other end is fixed with tensioning frame 5, tensioning frame 5 is added is provided with two symmetrically arranged spacing running rollers 7, and driving chain 2 passes between the wheel face of two spacing running rollers 7.
Further, the direction of axis line of two spacing running rollers 7 is parallel with the direction of axis line of the bearing pin on driving chain 2.
Further, the wheel face of two spacing running rollers 7 all forms the stopper slot 8 matched with driving chain 2.
Further, two spacing running rollers 7 are arranged on tensioning frame 5 by rotating shaft and bearing.
Further, nut 6 includes two, and it lays respectively at the both sides of studdle 3 and the sleeve hole of bracing frame 4.
Operation principle of the present utility model is: by regulating two nuts 6 position on studdle 3 during use, regulates the spacing between bracing frame 4 and tensioning frame 5, thus regulates the tensile force of driving chain 2.
The foregoing is only preferred embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all should belong to the scope of this utility model protection.
