Each oscillatory mass 14 generally includes first and second clump weights 14 with substantially flat shape1With 142,
Respectively with the first and second interareas 12 of supporting element 121With 122Extend face to face.
First and second clump weights 141With 142Preferably it is rigidly secured to each other by spacer 18.Spacer clamping
Between two clump weights and extend to supporting element rolling window 20 in.Spacer defines the roller track of oscillatory mass
22。
Therefore, each 16 one side of rolling member, which is supported on, is preferably limited by the Internal periphery of the rolling window of supporting element 20

8.The device particularly may include three, five or seven oscillatory mass.In the example depicted in fig. 1, which includes
Around equally distributed three oscillatory mass of axis X.
For each oscillatory mass, which includes pasting component 30, when supporting element is with the speed per minute less than 800 turns
When degree is around axis X rotation and especially when supporting element, which is in, to be stopped, pasting component 30 and be resiliently supported at and paste track
On 32.Track 32 is pasted by that may constitute with all the points for pasting the supporting element that component 30 contacts, especially in oscillatory mass
14 duration of oscillation.
According to the present invention, as shown in Figure 2 a, when observing device along axis X, the shape and supporting element of track 32 are pasted
The shape of roller track is essentially identical.In order to become apparent from, paste the roller track of track and supporting element in fig. 2 a with solid line and
Thick line is shown.
In the embodiment of Fig. 2,4 and 5, pastes track 32 and limited by the radially outward edge 15 of supporting element 12.Advantageously, it props up
Support member 12 lightens.In the fig. 3 embodiment, pasting the side for pasting window 40 in thickness of the track 32 by supporting element 12 is arranged in
Edge limits.
In the embodiment of fig. 2, component 30 is pasted in the first and second clump weights 141With 142Between compressed, so as to quilt
It shifts onto and pastes on track.By two clump weights, resilient separation and close ability obtain bearing elasticity each other.
Because clump weight leads to the power with centripetal component, corresponding clump weight 14 pasting the effect on component 301With 142
Pasting the supporting surface S on component 301And S2Inclination.As shown in Figure 2 b, along substantially at the center for pasting component 30 it is logical

In the embodiment of fig. 2, it pastes component 30 and is accommodated in and be separately positioned on the first and second clump weights 141With 142In
Pots 341With 342In ball.Preferably, chamber 341With 342Substantially square is circular, it is highly preferred that being radially oriented.
Therefore, it is separated from each other in two clump weights or close to period, chamber 341With 342Allow to paste component relative to clump weight slightly radially
Displacement.
In the embodiment of fig. 2, chamber 341With 342It is lateral.Chamber 341With 342Advantageously taper, for passing through axis
Radial force is generated to clamping.
In the fig. 4 embodiment, it pastes component 30 to be made of the roller 42 with axis Y, roller 42 is provided with the first He
Second pin 441With 442, the first and second pins 441With 442It is respectively received in and is respectively arranged at the first and second clump weights 141With 142

In this embodiment, bearing elasticity of the component on supporting element 12 is pasted preferably by the bullet with axis Y around roller 42
Property body ring 48 compression obtain.Preferably, ring 48 is contained in the peripheral groove 50 in the peripheral surface 52 for being limited to roller 42,
The peripheral groove 50 extends between the first and second clump weights.
The component that pastes of Fig. 5 pastes component similar to Fig. 4.However, elasticity is not due to pasting component 30 and pasting
There are caused by elastic ring between track 32, but the elastic bearing that the spring 60 by being coupled with oscillatory mass 14 applies causes
's.In the 5 embodiment of figure 5, spring 60 is leaf spring, and each of two end is fixed in oscillatory mass 14.More
Body, in the 5 embodiment of figure 5, the end of spring 14 is installed as along the axis for being parallel to axis X around pivot 621With 622Rotation
Turn, pivot 621With 622Respectively in two clump weights 141With 142Between extend.
Operation is derived directly from above-mentioned.
In use, goods of furniture for display rather than for use vibrates under the action of the aperiodicity of engine.The centrifugation being applied in oscillatory mass
Power depends on the rotation speed of supporting element.When the speed is high, at typically larger than 800 revs/min, oscillatory mass, which pushes, to be rolled
Component is against roller track.Therefore the rolling of rolling member is guided and is mute.In general, being applied to rolling by oscillatory mass
Power on dynamic component is greater than 50N, or even greater than 80N, preferably substantially 100N.The effect for pasting component is smaller, is, for example, less than
10N, or even zero.
When the rotation speed of supporting element reduces, the centrifugal force being applied in oscillatory mass reduces.Therefore, oscillating mass
Block tends to close to axis X.If they sufficiently close to axis X, rolling member is no longer able to be clipped in supporting element and oscillation
Between the roller track of mass block.
Supporting element 12 is flexibly pushed against by oscillatory mass 14 however, pasting component 30.Component 30 is pasted to exist
It pastes the bearing on track 32 to tend to leave oscillatory mass from axis X, but this leaves and is being vibrated by rolling member
The obstruction of bearing on the roller track of mass block.
Therefore, rolling member 16 is flexibly added with prestressing force, especially when being less than 800 turns of rotation speed per minute.
However, prestressing force has lower intensity, usually in position of rest less than 30 newton.The phase is rotated relative to supporting element
Between the pressure that is generated by centrifugal action, the prestressing force is especially substantially negligible.
In general, paste component 30 applies the power F including centripetal component on supporting element 12, it is preferably directed towards axis X and takes
To as shown in Figure 2 a.
Therefore, it pastes component 30 and resists displacement of the oscillatory mass towards axis X.
Track is pasted to be not necessarily positioned on supporting element.Similarly, it can be arranged in oscillatory mass.Paste component
Then it is coupled with supporting element.Preferably, the component that pastes being mounted on supporting element is constructed to be permeable to roll on pasting track.
Fig. 6 shows such embodiment.Pasting component includes the pin 70 being fixed on supporting element 12, and in the column
There are two ball bearings 72 for installation on pin 701With 722, the first and second clump weights 141With 142Pass through the first and second bullets respectively
Property ring 741With 742It leans against on the first and second ball bearings.
To be taken in, all equivalent technologies described in pasting when track is limited by supporting element can paste track by oscillation matter
Gauge block is implemented when limiting.
Now it is clear that allowing to ensure rolling member and roller track the present invention provides a solution
Permanent contact, but regardless of supporting element rotation speed how, especially when rotation speed is less than 800 revs/min.However,
The solution will not interfere the excellent operation of device, especially in high rotation speed, paste the effect of component with lower
Intensity.
In addition, even if the elasticity of bearing is it is also ensured that the smallest compressing force when rolling member or when pasting component wear.
Finally, the shape for pasting track, which is defined so that, keeps substantially constant by the compressing force for pasting component application, and
Angle Position regardless of oscillatory mass on supporting element.
The advantageously significant reduction of noise level in low rotation speed.In addition, the service life of device is increased.
Certainly, the present invention is not limited to above-mentioned specific embodiments.
