Abstract
The utility model discloses a kind of regulating wheel with rack-and-pinion, it is intended to solve regulating wheel installation difficulty in prior art, need to use special handling instrument, and the friction of motion of each component is big, causes the problem that service life reduces.Including tension structure, driving pulley and driven pulley, described tension structure includes gear, upper rack, lower tooth bar, upper regulating wheel, lower regulating wheel, top shoe and sliding block, described gear is rack-mount, top shoe and sliding block are rack-mount, described gear is meshed with upper rack and lower tooth bar, and described upper regulating wheel and lower regulating wheel are wound with conveyer belt.This utility model simple in construction, reasonable in design, it is easy to manufacture, the installation of the most convenient regulating wheel and the regulation and control to belt.
Description
Technical field
This utility model relates to the tensioning field of a kind of tension pulley, in particular it relates to the tension structure of a kind of tension pulley.
Background technology
Belt transmission is the kind of drive that machinery industry is conventional, and the belt of various material is not the most elastomer completely, under the effect of pretightning force, after operating after a while, will relax because of plastic deformation, makes initial tension reduce.In order to ensure the ability of V belt translation, the numerical value of initial tension need to be made regular check on.As found deficiency, it is necessary to re-tensioning, could normally work.When centre-to-centre spacing between belt wheel can not regulate, typically use tensioner apparatus.Conventional tensioner apparatus is that contact wheel is installed in fork one end, or installs contact wheel on a Height Adjustable support bar.The regulating wheel installation difficulty of these structures, needs to use special handling instrument, and the friction of motion of each component is big, causes reduce service life.
Utility model content
This utility model is in order to solve regulating wheel installation difficulty in prior art, need to use special handling instrument, and the friction of motion of each component is big, cause the problem that service life reduces, it is provided that a kind of novel, simple in construction, easy for installation can regulate and control belt and the regulating wheel with rack-and-pinion of radial force that wheel shaft is born.
A kind of regulating wheel with rack-and-pinion of the present utility model, including tension structure, driving pulley and driven pulley, described tension structure includes gear, upper rack, lower tooth bar, upper regulating wheel, lower regulating wheel, top shoe and sliding block, described gear is rack-mount, top shoe and sliding block are rack-mount, described gear is meshed with upper rack and lower tooth bar, and described upper regulating wheel and lower regulating wheel are wound with conveyer belt.
Described gear is fixed on support by bearing pin.Described upper rack, lower tooth bar and upper regulating wheel, lower regulating wheel are fixed on support by the slide bar with slide block.Described upper rack and lower tooth bar bearing are provided with spring assembly.
The beneficial effects of the utility model:
(1) simple in construction, manufacture, use, maintenance cost low, it is simple to be widely popularized.
(2) reasonable in design, service life is long.
(3) it is easy to regulate and control the radial force that belt and Pulley shaft are born, more meets engineering design simplicity thought.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: driving pulley 1, transmission band 2, lower tooth bar 3, gear 4, top shoe 5, upper regulating wheel 6, driven pulley 7, upper rack 8, lower regulating wheel 9, support 10 and sliding block 11.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains this utility model, it is not limited to this utility model.
This utility model is mainly made up of driving pulley 1, transmission band 2, lower tooth bar 3, gear 4, top shoe 5, upper regulating wheel 6, driven pulley 7, upper rack 8, lower regulating wheel 9, support 10 and sliding block 11.
Described tension structure includes gear 4, upper rack 8, lower tooth bar 3, upper regulating wheel 6, lower regulating wheel 9, top shoe 5 and sliding block 11, described gear 4 is installed over the mount 10, top shoe 5 and sliding block 11 are installed over the mount 10, described gear 4 is meshed with upper rack 8 and lower tooth bar 3, and described upper regulating wheel 6 and lower regulating wheel 9 are wound with conveyer belt 2.
Described gear 4 is fixing over the mount 10 by bearing pin.Described upper rack 8, lower tooth bar 3 and upper regulating wheel 6, lower regulating wheel 9 are fixing over the mount 10 by the slide bar with slide block.Described upper rack 8 and lower tooth bar 3 bearing are provided with spring assembly.
During use, upper rack 8 and lower tooth bar 3 can be driven with swing pinion 4, it is connected to the position of regulating wheel on tooth bar it is thus possible to change, then the effect of the radial force that the tightness of conveyer belt reaches belt and wheel shaft is born can be changed, and this apparatus structure is simple, easily fabricated, special handling instrument need not be used, solve the problem of regulating wheel installation difficulty in prior art.
