Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.In the following description, for clear exhibition
Show the present invention structure and working method, will be described by many Directional words, but should by "front", "rear",
The Word Understandings such as "left", "right", " outer ", " interior ", " outside ", " inside ", " on ", " under " are for convenience of term, without should be understood
For limited word.
Referring to Fig. 1, Fig. 2, the utility model generator torsion spring vibration damping belt wheel, including bearing 1, belt wheel 2, clutch spring
Component 3, torsion spring 4 and pivot 5,2 driving bearing 1 of belt wheel rotate, and the clutch spring component is arranged outside torsion spring 4
3, clutch spring component 3, which is coupled to the belt wheel 2 and passes through torsion spring 4, transmits torque to the bearing 1, wherein, it is described
Torsion spring 4 is made of the first spring 4-1 and second spring 4-2, and the first spring 4-1 is located at 3 and second bullet of clutch spring component
Between spring 4-2, the torsion spring 4 is made to be coupled with pivot 5, coupling refers to that torsion spring 4 is contacted with 5 outer surface of pivot.
The utility model torsion spring 4 is collectively formed by the first spring 4-1 and second spring 4-2, and bearing 1 is through the belt wheel 2
It drives and rotates, clutch spring component 3, torsion spring 4 and pivot 5 are arranged in belt wheel 2.Torsion spring 4 is located at clutch (attached drawing
To show) between pivot 5.Torsion spring 4 works as loading moment using the first spring 4-1 and second spring 4-2 paralleling models
It acts on spring, two spring collective effects of the first spring 4-1 and second spring 4-2, spring is in parallel so that system tool at this time
There is relatively low spring rate, to realize the effect of isolation torsional oscillation.
The problems such as in order to preferably solve the durability of torsional oscillation and spring, sets the first spring 4-1 as bulky spring,
Cross-sectional area is more than the cross-sectional area of the second spring 4-2.When system bears certain torque, inner ring hairspring i.e. the second bullet
Spring 4-2 is reversed to outer diameter and is bonded with outer ring bulky spring i.e. the first spring 4-1 internal diameters.First spring 4-1 of high elastic coefficient at this time
Account for leading role, the windup-degree of system raises changing value very little with torque, significantly improves the fatigue strength of spring.
In order to further optimize the technique effect of the utility model spring fatigue resistance, in one kind of the utility model
In embodiment, on the basis of foregoing teachings, the first spring 4-1 cross-sectional areas are the second spring 4-2 cross sections
Long-pending 1~2 times.
In order to further optimize the utility model technique effect, in the another embodiment of the utility model,
On the basis of foregoing teachings, gasket 8 is provided between the bearing 1 and clutch spring component 3.Steel disc can be selected in gasket 8,
It is placed between 3 liang of planes of bearing 1 and clutch spring component to provide supporting surface to clutch spring component 3.
Furthermore described 5 one end of pivot is provided with bushing 6, preferably described pivot 5 and 6 integrally connected of bushing, mechanism consolidate
Property is strong.Also, dustproof cover 7 in 6 one side of bushing is installed, improves protection the utility model dust-proof effect.
The operation principle of the utility model is as follows：When belt wheel 2 rotates, belt wheel 2 drives clutch spring component 3, double torsions
Spring 4 is towards one-directional rotation, so as to which pivot 5 be driven to rotate.When belt wheel 2 works normally, the first spring 4-1 and second spring 4-2 are total to
Same-action, the two is in parallel connection, therefore system spring rate is relatively low；When torque persistently rises, second spring 4-2 expansions and with the
One spring 4-1 is fitted closely, and significant change, bullet will not occur for the windup-degree of torque rise suffered by system but 4 entirety of torsion spring
The fatigue strength of spring system is enhanced, and has not only been met vibration isolation requirement, but also has been improved the endurance quality of spring.
Therefore, the utility model uses the torsion spring with different coefficient of elasticity, instead of conventional metals spring, is placed in pivot
It between clutch, is absorbed compared with hairspring and the vibration from engine that decays, Torsional Vibration when overcoming the engine to work, compared with
Bulky spring can bear high torque, effectively improve the durability of spring, avoid spring that fatigue failure occurs, improve the durable of product
Performance, and the utility model is designed reasonably had both met vibration isolation demand, made generator and front end wheel train operation more stable, and can increase
Strong system durability improves product competitiveness.The above is only the preferred embodiment of the utility model, is not limited to
The utility model, it is noted that for those skilled in the art, do not departing from the utility model technology original
On the premise of reason, several improvement and modification can also be made, these improvements and modifications also should be regarded as the protection model of the utility model
It encloses.
