Description
Technical field
The invention belongs to technical field of transmission, the more particularly to a kind of two-way automatic tensioner of non-equal brachiums.
Background technology
Dual directional tightener is in the train design that accessory belt drives intelligent electric machine, in electrical machine belt pulley both sides synchronous tension
Belt and the automatic takeup designed.Intelligent electric machine motor and serves as generator not during the work time, when it is served as
With under operating mode, the belt tension of electrical machine belt pulley both sides can change a lot.It is excessively high in order to reduce the moment switched in operating mode
Belt tension variation, Dual directional tightener no matter left arm or right arm, or even entire ontology can transport freely relative to pedestal
It is dynamic.So the compound movement of Dual directional tightener is with the uneven for power source of electrical machine belt pulley both sides belt tension, so that it is guaranteed that
In whole system operation, belt tension is unlikely to excessively high, while the skidding rate of belt and electrical machine belt pulley can reduce, to extend
The service life of belt.
In the stretcher course of work of foregoing description, there are two important functional parameters, and one is spring torque, another
A is damping torque.The work behavior of product is directly determined by the two functional parameters.
Current line has in the industry some overseas companies to have developed such product, and has been matched to some of client
In mesh.Such as Bell Co. is admired by Germany, is to involve in this industry earliest, and volume production in global range.But it is produced
The Function of product is overly dependent upon the design of corresponding train layout, such as the spring of product is very single, if design
Person needs to adjust the applied tension of belt, can only be realized by way of changing train layout, and the damping design of product is also excessively
Limitation, the generation of damping are also to rely on the trend of belt in layout, i.e. cornerite of the belt on belt wheel.Such design,
Prodigious limitation is brought to the application work of designer and client.Meanwhile product structure is excessively complicated, cost is excessively high.
Invention content
To solve the above problem present in the prior art and actual conditions, the present invention provides the non-equal brachiums of one kind are two-way

Wheel assembly coordinates with belt；Cover board for will be inserted on sliding bearing damping fin I, damping fin II, Rocker arm assembly, auxiliary spring,
Auxiliary spring retainer compresses, is fixed in the axial direction, and eventually by the rotation riveter skills of pedestal, cover board is fixed；Damping fin I, damping
Piece II is used in rocking arm rotary course or two Rocker arm assemblies are relative to generation friction in pedestal rotary course, and then generates train
Work required damping torque；The pedestal of unidirectional auto-tensioning wheel assembly and the rocking arm of Rocker arm assembly are integrated.
Preferably, unidirectional auto-tensioning wheel assembly is internally provided with helical spring, and when work, unidirectional automatic tensioner is first put
It is dynamic, then push the unidirectional tensioning wheel pedestal of itself and Rocker arm assembly one to rotate by internal spring；Because of pedestal and rocking arm
Assembly is integrated, so the belt wheel on Rocker arm assembly can push belt to be tensioned.
Preferably, when the unidirectional automatic tensioner is swung relative to the pedestal of its own, inside can generate friction resistance
Buddhist nun；Meanwhile when unidirectional automatic tensioner pedestal rotation forces Rocker arm assembly is swung, another resistance will produce by damping fin
Buddhist nun；In turn, when the elastic variation of belt pushes Rocker arm assembly to swing, Rocker arm assembly can directly generate damping by damping fin,
It is internal to generate the damping of oneself again when the passive rotary oscillation of next unidirectional tensioning wheel.
Preferably, damping fin I is positioned by protrusion and the pit on auxiliary spring retainer.
Preferably, damping fin II is positioned by protrusion and the pit on seat surface.
Preferably, auxiliary spring retainer is mutually positioned with cover board by mutual notch and protrusion in the circumferential, Jin Erfang
Only auxiliary spring retainer rotates..
The present invention is non-to wait the two-way automatic tensioner of brachiums：
Spring torque：It is generated by the spring inside unidirectional automatic tensioner, main purpose is to provide the belt work of system
Tension.
Damping torque：When unidirectional automatic tensioner is swung relative to the pedestal of its own, inside can generate frictional damping.
Meanwhile once unidirectional automatic tensioner pedestal rotation forces Rocker arm assembly, when swing, will produce another layer by damping fin
The damping in face.In turn, when the elastic variation of belt pushes Rocker arm assembly to swing, Rocker arm assembly can be generated directly by damping fin
Damping, it is internal to generate the damping of oneself again when the passive rotary oscillation of next unidirectional tensioning wheel.
Decoupling damping：It is generated relative to the rotation of pedestal by Rocker arm assembly.
This design structure is compact, and the not too many special material of the material that parts use, cost compares relatively low.
Function adjusts：
A. belt tension：By adjusting the rigidity of unidirectional automatic tensioner contained spring, you can to adjust its spring rate, into
And change the spring torque of tensioning wheel, the final belt tension for changing system.
B. frictional damping：By adjusting the rigidity of auxiliary spring, the normal pressure in damping fin friction process can be adjusted, finally
The purpose of adjustment product damping torque may be implemented.So this design has application aspect the flexibility of height.
