Technical field
The present invention relates to a kind of mechanical assembly, related in particular to a kind of novel friction type auto-tensioning wheel.
Background technique
In the Timing Belt transmission system of motor car engine; Engine timing system on the market has adopted usually, and adjustable/center fixation formula idle pulley comes tightening belt; But this assembly usually can cause various problems, for example: have inconsistent belt tension between the different motors; Regularly need adjustment belt tension (the 20000km adjustment once usually); Can not compensate because the influence that apron drawing, wearing and tearing and engine thermal expand and bring; The control of belt life belt tension is poor; The belt tension control is poor under the situation of temperature variation.These problems need bring a lot of inconvenience can for daily life and production, so need a kind of mechanical assembly that more can satisfy people's demand to replace the equipment of center fixation formula idle pulley on the market.
Summary of the invention
The present invention mainly is the deficiency to existing technology, and the novel friction type auto-tensioning wheel of a kind of high working efficiency, long service life is provided.
To achieve these goals, the present invention provides following technological scheme:
A kind of novel friction type auto-tensioning wheel; It is characterized in that: it comprises that it comprises eccentric mounting arm, thrust washer, bearing, belt wheel, central axle sleeve, eccentric working arm, spring, base, and eccentric mounting arm is made up of installation shaft and pivot, and installation shaft comprises guide pillar and pad; Said each parts are assembled through nested mode; Be provided with said thrust washer between installation shaft and the said pivot, the outer ring of pivot is connected with said central axle sleeve, and bearing is located in the belt wheel; Spring is located between said eccentric working arm and the base, and said base is positioned at auto-tensioning wheel bottom.
As a preferred embodiment of the present invention, said eccentric working arm is rotated around said bearing.
As a preferred embodiment of the present invention, said pivot has adopted concentric pivot.
As a preferred embodiment of the present invention, said installation shaft has adopted eccentric installation shaft.
As a preferred embodiment of the present invention, said installation shaft comprises guide pillar and pad, and the radius of said pad is greater than said cylinder radius.
As a preferred embodiment of the present invention, said pad center is provided with hole.
As a preferred embodiment of the present invention, is furnished with installation function hexagonal hole on the said installation shaft.
Can find out from technique scheme; The present invention has adopted novel friction type auto-tensioning wheel to replace center fixation formula idle pulley; It not only can improve the efficient of synchronization control and transmission in correct time, reduces dynamic load and vibration in the transmission system system, does not need regularly to adjust belt tension; And the working life that can also improve each parts in the transmission system in correct time, reduce system noise simultaneously.
Description of drawings
Fig. 1 is the structural representation that the novel friction type auto-tensioning of the present invention is taken turns a preferred embodiment;
Fig. 2 is the three-dimensional structure diagram after the assembling of the said novel friction type auto-tensioning wheel of Fig. 1;
Among the figure: 1, installation shaft, 2, thrust washer, 3, bearing, 4, belt wheel, 5, central axle sleeve, 6, eccentric working arm, 7, pivot, 8, spring, 9, base.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Consult Fig. 1 and Fig. 2, Fig. 1 is the structural representation that the novel friction type auto-tensioning of the present invention is taken turns a preferred embodiment; Fig. 2 is the three-dimensional structure diagram after the assembling of the said novel friction type auto-tensioning wheel of Fig. 1.
A kind of novel friction type auto-tensioning wheel; It comprises eccentric mounting arm, thrust washer 2, bearing 3, belt wheel 4, central axle sleeve 5, eccentric working arm 6, spring 8, base 9, and said eccentric mounting arm is made up of installation shaft 1 and pivot 7, and said installation shaft 1 comprises guide pillar and pad (not indicating); Said each parts are assembled through nested mode; Be provided with said thrust washer 2 between said installation shaft 1 and the said pivot 7, the outer ring of said pivot 7 is connected with central axle sleeve 5, and said bearing 3 is located in the said belt wheel 4; Said spring 8 is located between said eccentric working arm 6 and the said base 9, and said base 9 is positioned at the bottom of said auto-tensioning wheel.
Each parts of said novel friction type auto-tensioning wheel carry out nested assembling according to its size, make that so not only the structure of assembly is more simply clear, and the installation and removal of taking turns for said novel friction type auto-tensioning provide convenience.
Said novel friction type auto-tensioning wheel has adopted several quality and elastic element; Quality elastic belt system produces the angle torsional oscillation under the load effect; And the axle center load that acts on the tensioner arm is delivered on the pivot through lining, thereby produces frictional force and kinetic damping.
Said pivot 7 has adopted eccentric pivots, and said installation shaft 1 has adopted eccentric installation shaft.Belt is after long-term the use, and it is elongated to tend to fluff, and the easy like this belt that causes is loose excessively, can't normally move, and needs to change belt.And choose the generation that offset assembly can be avoided this situation, and mainly be because eccentric design can compensate motor and make tolerance and belt tolerance, and sustained Idle wheel mounting point can be provided, make the life-span of each parts prolong, cut the waste.
Said eccentric working arm 6 is rotated around said bearing 3, and said novel friction type auto-tensioning wheel compensates the stretching and the wearing and tearing of expanding with heat and contract with cold of motor and belt through the rotary work arm.
Said installation shaft 1 comprises guide pillar and pad (not indicating), and the radius of said pad is greater than said cylinder radius, and said pad center is provided with hole, is furnished with installation function hexagonal hole on the said installation shaft 1.
Said novel friction type auto-tensioning wheel can be kept suitable belt tension through wearing and tearing of compensation apron drawing and the shrinkage of motor heat expansion, and adopts the vibration of frictional damping technology control system.In order to control belt tension and the belt tension that is consistent, the friction type tension assembly can satisfy the functional requirement that alternative center fixation formula idle pulley is possessed fully.
The present invention has adopted novel friction type auto-tensioning wheel to replace center fixation formula idle pulley; It not only can improve the efficient of synchronization control and transmission in correct time; Reduce dynamic load and vibration in the transmission system system; Do not need regularly to adjust belt tension, and the working life that can also improve each parts in the transmission system in correct time, system noise reduced simultaneously.
The above; Be merely the embodiment of the preferred embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.
