Specific implementation mode
A kind of high ferro wheel noise reduction circle with reference to shown in Figure of description 1, looks like a kind of bearing arrangement on the whole,
Although increasing some circle body structures, has the feature of bearing on the whole, therefore, bearing has true as standard component
Fixed axis, and require that there is certain concentricity between inner ring 3 and outer ring 1 in principle.Based on corresponding axis, really
The axis of inner ring 3 has determining centripetal, the such reference data of centrifugation on bearing.
And for bearing, width refers to its axial maximum length.
In the construction shown in fig. 1, basic framework is inner ring 3, outer ring 1 and the rolling between inner ring 3 and outer ring 1
Body component.
Wherein, rolling element component is as conventional bearings, the rolling element 2 for having retainer 4 and being positioned by retainer 4,
In the embodiments of the present invention, rolling element 2 is not generated directly with inner ring 3 and outer ring 1 and is contacted, and is further increased in Fig. 1
Four circle bodies, are sequentially interior steel ring 10, inner rubber layer 9, outer rim 7, outer rubber layer 8, inner rubber layer 9 therein from the inside to the outside
Circle body structure is also shown as with the main body of outer rubber layer 8.
In Fig. 1, inner ring 3, inner rubber layer 9 and interior steel ring 10 form interior buffer structure, are denoted as internal damping assembly；It is outer ring 1, outer
Steel ring 7 and outer rubber layer 8 form outer buffering assembly, are denoted as external damping assembly.It is illustrated for one of them below, it is another
A structure is roughly the same with its, therefore, is illustrated below for external damping assembly：
External damping assembly includes mainly three parts, i.e., outer ring 1, outer rim 7 and outer rubber layer 8 above-mentioned, wherein outer ring
1 can be as existing outer ring 1.It is generally only a regular circle body knot with interior outer cylinder for conventional outer ring 1
Structure（The gabarit both ends of outer ring 1 usually have rounding）, and in the embodiments of the present invention, outer ring 1 can be the circle body of rule
Structure can also go out locating slot, for the axially position of outer rubber layer 8 in its inner wall structure.Correspondingly, outer rubber layer 8
There are one the ridge-like structures that can be embedded in the locating slot for gabarit tool, are conducive to the reliable location of outer rubber layer 8, prevent it from outer ring
1 abjection.
For outer rim 7, which is nested in outer ring 1, and there are assembly spaces between the two, and outer rubber layer 8 is embedding
It is sleeved in the assembly space.
Due to needing to provide raceway for rolling element 2, about raceway, it should be noted that for bearing, generally require
Raceway is constructed on inner ring 3, in the embodiments of the present invention, since there are elastomeric element, raceway is needed in internal damping assembly
It builds on external damping assembly, deviates to avoid rolling element component simultaneously.This is different from bearing, and bearing is usually only on inner ring 3
Build raceway.
It is adapted with outer ring 1, the locating slot for 8 axially position of outer rubber layer can also be set on inner ring 3.
In turn, about raceway comprising correspond to the interior rollaway nest part of the centripetal side of rolling element component and correspond to rolling element
Component centrifuges the outer rollaway nest part of side, wherein outer rollaway nest part constructs on external damping assembly, and interior rollaway nest part is constructed in internal resistance
On Buddhist nun's assembly, two groove portion split-phases seemingly, below other than raceway part construction for illustrate.
Outer rollaway nest part only construction can also partly can construct in outer rim 7, partly construct on outer rim 7
On outer rubber layer 8.It should be noted that it can also be roller that rolling element 2, which can be ball, but no matter which kind of, all there is
Curved surface gabarit, even by 8 jointly constructs of outer rim 7 and outer rubber layer, the raceway part on outer rim 7 is also wider than raceway
Part on outer rubber layer 8.
Thus, due to the presence of outer rubber layer 8, on the one hand it wants the transmission capacity of mechanical wave compared to bearing steel
Much weaker, so as to play the role of certain mechanical wave resistance every simultaneously as its own generates the ability of mechanical oscillation very
It is weak, to there is extraordinary damping effect.
In contrast, compared to traditional bearing, 1 diameter of outer ring is relatively large, for this purpose, in order to keep high ferro wheel to drop
It makes an uproar the use reliability of circle, width can be relatively large, and width selects 1.2 ~ 1.5 times of the bearing width of same size.
It is related to use reliability, further, as far as possible using being fixedly connected between outer rim 7 and outer ring 1, in other words,
External damping assembly is equivalent to outer ring 1 on the whole, and internal damping assembly is equivalent to inner ring 3 on the whole, in equivalent outer ring 1 and inner ring
Under 3 technologies require, the keeing relative stability of internal damping assembly and external damping assembly integrality is allowed.
Due to such as outer rubber layer 8, rolling element 2 and outer ring 1 are mainly separated, this separate is radial in outer ring 1
It separates, therefore, based on the width of outer ring 1, can have relatively large connection space for the company between outer ring 1 and outer rim 7
It connects, in addition, the connection structure between outer ring 1 and outer rim 7 has no effect on the continuity of outer rubber layer 8, as shown in Fig. 2, due to
Tie point can have that there are two the parts between screw hole 12 on the both sides of 7 width direction of outer rim, outer rubber layer 8, in addition,
Screw hole 12 can also include the part on outer rubber layer 8, i.e., the via passed through for screw is provided in outer rubber layer 8.
In turn, outer rim 7 has the outer tie point at least two and not more than being used to connect with outer ring 1 everywhere, multiple outer
Tie point is circumferentially set in outer rim 7, and connection direction is connected from 7 side of outer rim to 1 side of outer ring, does not influence the appearance of outer ring 1,
Correspondingly, part of the screw hole 12 on outer ring 1 is blind hole.
Accordingly for inner ring 3, corresponding to screw bore portion be also blind hole, be subject to corresponding interior tie point and also adopt
With the connection structure connected from 10 side of interior steel ring.
Further, in order to avoid outer rubber layer 8 is formed with to premature failure at outer tie point by excessive condensation
The outer backing plate 6 being supported between outer rim 7 and outer ring 1, outer rim 7 are rigidly connected by outer backing plate 6 and outer ring 1.
Be subject to it is corresponding, between inner ring 1 and interior steel ring 10 also use similar rigid connection structure.
Due to being mainly used for being rigidly connected, larger cushion space, rigidly connected presence are occupied without outer backing plate 6
Certain buffer capacity is reduced, but influences not being clearly.
It is configured about structure, outer rim 7 is identical as the thickness of outer ring 1, and less than the thickness of outer rubber layer 8；In spite of this
The technology requirement of sample, but outer rubber layer 8 is unsuitable blocked up, otherwise can influence the reliability of entire high ferro wheel noise reduction circle, therefore, outside
The thickness of rubber layer 8 is not more than 1.2 times of 7 thickness of outer rim.
In a preferred embodiment, outer rim 7 and the thickness of outer ring 1 are selected as 3.5mm, and the thickness of outer rubber layer 8 is
4mm.3.5mm is also selected to for the thickness of inner ring 3 and interior steel ring 10, the thickness of inner rubber layer 9 is selected as 4mm.
