Accompanying drawing for.They are not used to limit the absolute position of involved parts, but can change as the case may be.
Fig. 1 shows the overall structure of vibration damping support device 100, and the vibration damping support device 100 is particularly useful for wind-force
The vibration damping of the gear-box of generating set.As illustrated, the vibration damping support device 100 includes housing.In this embodiment, housing bag
Upper half-shell 10 and housing lower half 20 are included, they have collectively constituted a complete confined space.
Vibration damping support device 100 also includes mandrel 30, and it is positioned partially in housing, and is placed through upper half-shell 10
Opening 11 in top and extended out from housing.The upper end of mandrel 30 is connected on ring flange 40, and passes through ring flange 40
Bear the torsional moment from vibration source (such as gear-box of wind power generating set).The region in housing on mandrel 30 is set
There is shoulder 31, its both sides is respectively equipped with inclined-plane.
The elastic component 50 in top and the elastic component 50 being below are disposed with the inner space of housing.The two
Elastic component is configured to volute spring, and their taper direction is opposite each other, is respectively facing the axle of upper shell 10 and lower house 20
It is gradually reduced, and is arranged on the inclined-plane of the both sides of shoulder 31 laterally.Two elastic components 50 use and are embedded with metal bone
The elastic rubbery body of frame.Metallic framework is generally formed by the metal partion (metp) of multiple substantially equalitys each other.Mandrel 30, the and of ring flange 40
The structure of the elastic component 50 of volute spring formula is well known to the skilled artisan in the art, for the sake of saving length, herein
In omit its detailed description.
As described above, the housing of vibration damping support device 100 includes upper half-shell 10 and housing lower half 20.The two half shells
With substantially the same structure, therefore hereinafter illustrated for convenience of for the sake of by taking upper half-shell 10 as an example.Such as without spy
Do not mentionlet alone bright, all structural descriptions for upper half-shell 10 are applied to housing lower half 20.
Fig. 2 and 3 respectively illustrates the cross section of the upper half-shell 10 in vibration damping support device 100 of the present utility model
View and stereogram.As illustrated, upper half-shell 10 is constructed to the form of generally cylindrical body.It is outside in the week of upper half-shell 10
Side is provided with the substantially u-shaped groove 12 of a circle.Preferably, U-lag 12 is arranged uniformly in the circumferential direction, and along upper half-shell 10
Axially through whole upper half-shell 10 (as shown in Figure 3).In the illustrated embodiment, it is disposed with 16 U-lags 12 altogether, adjacent two
22.5 degree are spaced between individual U-lag 12.One circle U-shaped of outer circumferential of these U-lags 12 with being similarly disposed at housing lower half 20
Groove 12 is in alignment with each other (see Fig. 1), and unshowned connector (such as bolt-nut connector) extends there through, so as to by upper half shell
Body 10 and housing lower half 20 are connected to each other.
As shown in Fig. 2 U-lag 12 includes the circular arc portion 12A positioned at radially inner side, and opening wide positioned at radial outside
Slot-open-section 12B.Slot-open-section 12B width is arranged to be slightly larger than the company for being used for connecting upper half-shell 10 and housing lower half 20
The diameter of fitting (such as bolt), so that connector can be inserted into U-lag 12 from shown in side along arrow A.Additionally, it is preferred that
It is that circular arc portion 12A diameter is chosen to the width slightly larger than slot-open-section 12B so that bolt can be in U-lag 12 freely
Ground rotates.
Because the height of housing is typically greater than housing the distance between to ring flange, therefore, for connecting upper half-shell
10 and the connector (such as bolt) of housing lower half 20 can not be assembled because of the interference effect of ring flange above housing, because
And bring great inconvenience to assembly working.According to the utility model, by being provided in upper half-shell 10 and housing lower half 20
U-lag 12 as described above, connector just can be radially inserted into U-lag 12 from side, so as to connect upper half shell
Body 10 and housing lower half 20.Therefore, the interference effect of ring flange is avoided, and is capable of the dress of upper half-shell 10 and housing lower half 20
With can easily carry out.
In addition, by opening up U-lag 12 as described above in upper half-shell 10 and the circumferential lateral surface of housing lower half 20, have
Eliminate to effect a part of material of upper half-shell 10 and housing lower half 20 so that upper half-shell 10 and the weight of housing lower half 20
Great mitigation is obtained.Simultaneously as U-lag 12 is only opened in the circumferential lateral surface of housing, therefore the rigidity of whole housing
Will not be significantly affected with intensity.By this design, the overall weight of vibration damping support device 100 is dropped simultaneously
It is low, be advantageous to the raising of effectiveness in vibration suppression.
In order to further mitigate the overall weight of vibration damping support device 100, according to the utility model, in upper half-shell 10
A part for radial outside has been cut off on top surface, has formd the boss 13 of a frustum form in center, such as Fig. 1 and
Shown in 3.The substrate diameter of a circle of the boss 13 is slightly less than the straight of the imaginary circle that is made up of the bottom land center of each U-lag 12
Footpath.Preferably, the substrate diameter of a circle of the boss 13 is than the imaginary diameter of a circle that is made up of the bottom land center of each U-lag 12
Small (0.5-1) * R, wherein R are the circular arc portion 12A of U-lag 12 radius.In addition, the height of the boss 13 for example may be selected to
(0.05-0.1) * H, wherein H are the height of upper half-shell 10.By this design, on the one hand can mitigate to greatest extent on
The weight of half shell 10, it on the other hand can ensure that upper half-shell 10 has enough strength and stiffness, because its center
The thickness in region keeps constant.
It is although not shown in figure, it being understood, however, that if desired, can also be on the bottom surface of housing lower half 20
Similar boss is formed by material removal.
