Description
Technical field
The utility model belongs to mechanical transmission fields, and in particular to a kind of adjustable roller chain tension means.
Background technology
Roller chain drives are a kind of wider machine drivings of application.It by the driving and driven sprocket wheel on parallel axes and around
Ring chain on sprocket wheel is formed, and passing power and motion are engaged by chain and sprocket teeth, in long range is driven,
Chain is because the gravity of itself relaxes, and when lacking tensile force, chain can be made to produce vibration, and it is different that jump tooth, de- chain, chain occurs
Often the problems such as abrasion, and traditional tensioning apparatus is heavy, is not easy to adjust, and dismounts complicated.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of above-mentioned background technology, there is provided a kind of adjustable roller chain tensioning
Device, its is simple in construction, is easily installed, can effectively tension rollers chain, and can adjust pretightning force at any time.
In order to realize the above object a kind of adjustable roller chain tension means provided by the utility model, including tensioning wheel,
Fixing axle, balladeur train, guide holder, adjusting screw rod, spring, stop nut and packing ring；The tensioning wheel is arranged on by fixing axle and slided
On frame, the guide holder is set in outside balladeur train, and balladeur train is provided with boss sliding block, is provided with guide holder and is engaged with boss sliding block
Guide groove, the adjusting screw rod passes through from balladeur train, spring, guide holder center successively, the both ends stop nut of adjusting screw rod
And packing ring fixes locking.Before device installation, pretightning force is adjusted, by spring-compressed, interior external application stop nut and washer locking are consolidated
It is fixed, after the device is installed in place, unclamp outside（That is this side of guide holder）Stop nut and packing ring, spring extends naturally to slide
Frame is moved along the guide groove in guide holder to chain direction to be tensioned, and the purpose of tension chain is reached with this.
In the above-mentioned technical solutions, the guide holder end is provided with limiting plate, and limiting plate is bolted on guide holder
On, prevent balladeur train from skidding off guide holder, play spacing effect.
In the above-mentioned technical solutions, the guide holder is bolted on the support by roller chain to be tensioned,
Make the adjacent chain of tensioning wheel.
The utility model can adjust roller chain tension means, extends the balladeur train equipped with tensioning wheel naturally by spring and exists
Moved in guide holder towards roller chain direction, so as to reach the effect of tension rollers chain.The utility model is reasonable in design, simply
Easily make, small volume, be easy to dismount, cost is low, efficiently solve roller chain chain caused by tensile force is inadequate release and
The problems such as chain inordinate wear, it is adapted to the tensioning of various roller chains, such as chain-linked conveyer, checks line driving-chain.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model device.
Fig. 2 is Fig. 1 Section A-A figure.
In figure, 1. tensioning wheels, 2. fixing axles, 3. balladeur trains, 4. guide holders, 5. adjusting screw rods, 6. springs, 7. stop nuts and

Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type embodiment is described in further detail.
As shown in Figure 1, 2, a kind of adjustable roller chain tension means of the utility model embodiment offer, including tensioning wheel 1,
Fixing axle 2, balladeur train 3, guide holder 4, adjusting screw rod 5, spring 6, stop nut and packing ring 7, limiting plate 8；The tensioning wheel 1 passes through
Fixing axle 2 is arranged on balladeur train 3, and the guide holder 4 is set in outside balladeur train 3, and balladeur train 3 is provided with boss sliding block, in guide holder 4
Provided with the guide groove being engaged with boss sliding block, the adjusting screw rod 5 passes through from balladeur train 3, spring 6, the center of guide holder 4 successively,
Balladeur train 3, spring 6 are coupled with guide holder 4, before device installation, pretightning force is adjusted, spring 6 is compressed, the both ends of adjusting screw rod 5
Locking is fixed with stop nut and packing ring 7.When the device is installed, guide holder 4 is bolted on roller chain to be tensioned
On other support, make 1 adjacent chain of tensioning wheel.After the device is installed in place, outside is unclamped（That is this side of guide holder）Locking spiral shell
Female and packing ring 7, spring 6 extends naturally causes balladeur train 3 to be moved along the guide groove in guide holder 4 to chain direction to be tensioned.It is described
Limiting plate 8 is fixed by bolts on guide holder 4, prevents balladeur train 3 from skidding off the guide groove in guide holder 4, plays spacing effect.
The content not being described in detail in this specification, belong to prior art known to those skilled in the art.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
