Abstract
The utility model discloses a chain tensioning mechanism, which comprises a base plate. A triangular regulating plate is mounted on the base plate in a rotating fit manner, one of base angles of the triangular regulating plate is matched with the base plate rotationally while the other base angle is provided with a slotted hole, a positioning pin penetrates through the slotted hole to be fixedly connected with the base plate, a driving sprocket is rotationally mounted at the vertex angle of the regulating plate, a driven sprocket is arranged on the outer side of the driving sprocket, and an annular chain is disposed between the driving sprocket and the driven sprocket in a meshing manner. The chain tensioning mechanism is simple in structure, the chain is tensioned by means of adjustment of relative position between the driving sprocket and the driven sprocket, loosening in meshing among the chain, the driving sprocket and the driven sprocket is avoided, transmission efficiency of the driving sprocket and the driven sprocket is increased, and accordingly the chain tensioning mechanism has higher practical value.
Description
Technical field
The utility model relates to a kind of chain tensioning mechanism.
Background technique
Sprocket wheel is the wheel of band inserted tooth formula whelp, in order to pitch chain ring or cable on pitch accurately block be meshed, be a kind of gear of solid or band spoke, with chain engages with transmitting movement.
Sprocket wheel is widely used in the mechanical transmission of industries such as chemical industry, textile manufacturing machine, food processing, instrument, oil etc.Sprocket wheel can use in pairs, and drive sprocket and driven sprocket are engaged with chain between drive sprocket and the driven sprocket respectively, and in long-term using process, becoming flexible can appear in engagement between chain and drive sprocket and the driven sprocket unavoidably, thereby influences the transmission effect.
The model utility content
The purpose of this utility model provides a kind of chain tensioning mechanism, by regulating the relative position between drive sprocket and the driven sprocket, reaches the purpose of tension chain, thereby avoids the engagement between chain and drive sprocket and the driven sprocket to occur loosening.
The technical solution of the utility model is as follows:
A kind of chain tensioning mechanism, include base plate, it is characterized in that: the regulator plate that triangular shape is installed by being rotatably assorted on the described base plate, the place, a base angle of described regulator plate is rotatably assorted with described base plate, another place, base angle of regulator plate is provided with bar hole, have locating stud to pass described bar hole and fixedly connected with described base plate, the drift angle place of described regulator plate is rotatablely equipped with drive sprocket; The outside of described drive sprocket is provided with driven sprocket, is engaged with ring chain between the described driving and driven sprocket wheel.
Described chain tensioning mechanism is characterized in that: described drive sprocket is provided with motor outward, and described motor and described drive sprocket are in transmission connection.
The beneficial effects of the utility model:
The utility model is simple in structure, by regulating the relative position between drive sprocket and the driven sprocket, reach the purpose of tension chain, thereby avoided the engagement between chain and drive sprocket and the driven sprocket to occur loosening, and then improved transmission efficiency between the driving and driven sprocket wheel, have good use value.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of chain tensioning mechanism, include base plate 1, the regulator plate 2 of triangular shape is installed by being rotatably assorted on the base plate 1, the place, a base angle of regulator plate 2 is rotatably assorted with base plate 1, the place, another base angle of regulator plate 2 is provided with bar hole 3, has locating stud 4 to pass bar hole 3 and fixedlys connected with base plate 1, and the drift angle place of regulator plate 2 is rotatablely equipped with drive sprocket 5; The outside of drive sprocket 5 is provided with driven sprocket 6, is engaged with ring chain 7 between the driving and driven sprocket wheel 5,6.
Be provided with motor outside the drive sprocket 5, motor and drive sprocket 5 are in transmission connection.
When ring chain 7 takes place to become flexible, manual loosening locating stud 4 makes regulator plate 2 rotate an angle on base plate 1, thereby changes the relative position between the driving and driven sprocket wheel 5,6, make ring chain 7 be in tensioning state, eliminate the loosening phenomenon of ring chain 7.
Claims (2)
