Electric insulation resin cast or is injected into bobbin 18A, 18B using appropriate mould upper and cast or be injected into circle
On cylindrical ring 17c outer surface, and cast or injection is formed in gap between the bobbin and outer shroud 17b, so as to
Closed circle structure 19 (Fig. 3 to Fig. 6) is formed in component.
Then, the stator 7 being thusly-formed for example is attached to the support of accumulator using screw 20 and related sleeve pipe 21
The rear wall 3f of the half-shell 3 of shell, the latter is preferably made up (referring also to Fig. 3) of elastomeric material.
With specific reference to Figure 14 to Figure 18, each support equipment 10 for the end 9a of axle 9 has (specific by Heat Conduction Material
For be metal) the inner annular support member 30 that is made, wherein form substantially cylindrical seat 30a, the phase for the axle 9
Close end.
In shown embodiment (referring specifically to Figure 16), there is inner annular support member 30 edge to be arranged essentially parallel to cylinder
The gap 30b of the direction extension of shape seat 30a axis.Gap 30b cause inner annular support member 30 formed it is adjacent to each other but
Separated Liang Ge branches or two bifurcateds 30c and 30d.
The inner annular support member 30 of each support equipment 10 is inserted into matching seat 31a, and the matching seat 31a formation exists
In the outer support members 31 being conveniently fabricated by elastomeric material (such as elastomer).
In an illustrated embodiment, the profile of inner annular support member 30 is substantially quadrangle.Correspondingly, external support
The seat 31a of component 31 is also substantially quadrangle.
In the embodiment shown in the figures, the profile of outer support members 31 is also substantially quadrangle.
With specific reference to Figure 16 and Figure 18, each heat transfer member 33 and 34 is attached to bifurcated 30c and 30d using screw 32
Flat upper surfaces.
In an illustrated embodiment, heat transfer member 33 and 34 is substantially the form of metal tape, once it is attached to inner loop
The bifurcated 30c and 30d (such as using screw) of shape support member 30, extend through corresponding recess 31b, and the recess 31b is formed
In the seat 31a for the corresponding outer support members 31 being made up of elastomeric material top side.
When assembling accumulator 1, the heat transfer member 33,34 of support equipment 10 and the rear wall of the half-shell 3 and 4 of support housing 2
Be in close contact so that by the operation of gyrating mass 11 and axle 9 when produced heat easily by the heat transfer member 33,34
Support housing 2 is transferred to, is subsequently dispersed in the environment of surrounding.
Such as Figure 16 and Figure 17 is more clearly shown, and is formed in the lower horizontal branch 31c of each outer support members 31
Substantially vertical through hole 31d.The bar 35 being made up of rigid material (such as metal) be placed in the through hole 31d (referring also to
Figure 14 and Figure 15).
As Figure 15 is specifically shown, the upper end of each rigid rod 35 is towards related support member 30 and is separated by perpendicularly thereto
Preset distance.
Bar 35 is advantageously used for stopping element, in the presence of axle 9 and the overall weight of gyrating mass 11, in resilient support
In the case that component 31 is bent, support member 30 is easy to collision on stopping element.
In fact, determining that the length of rigid rod 35 make it that after spring support member 31 is bent accumulator 1 is in office
What also can acceptably it work in the case of, although the damping action that can be provided under normal operation without these latter.
Easily, the size of the vertical thickness of the horizontal branch of spring support member 31 can be set to so that storage ought be debugged initially
During energy device 1, the axis of axle 9 and related gyrating mass 11 extends higher than optimal design high perpendicular, and this allows at least portion
Point ground pre-compensation is due to (the specifically lower horizontal point of spring support member 31 in the presence of the weight being applied to it
Branch) continuous bending and cause follow-up " decline " of the component.
Easily, the device of the rotary speed for sensing gyrating mass 11 (can for example detect rotor 11-13 permanent magnetism
Pass through three hall effect sensors of body 43) it can be assembled in connection component 8 (Fig. 1 and Fig. 2).
Referring again to Figure 15, the tubular element 40 for being restricted to rotate together with gyrating mass 11 is conveniently disposed at bearing
Between 13.
Being located towards the end of the tubular element 40 of the bearing 13 has corresponding upper conical surface substantially
40a, the half-shell 3 and 4 of its support housing away from accumulator is assembled towards axis A-A.
In addition, forming ring 42 is attached at the block 12 of gyrating mass 11 at axially opposing position and using screw 41
In.These rings extend in the outside of the bearing 13 of the opposite side of the end relative to tubular element 40 at least in part.
Specifically, forming ring 42 limits the corresponding of the convergence of half-shell 3 and 4 of the shell towards axis A-A and accumulator 1
Substantially upper conical surface 42a.
The conical surface 40a and 42a that is thus formed on the side of each bearing 13 is so that grease or other lubricants
Splashing can reach their desired devices, and the lubricant has a down dip with the turning effort of the high angular velocity of gyrating mass 11
To in " centrifugation " operation.
In operation, low-intensity acoustic noise is produced according to the accumulator of the present invention.If accumulator be arranged on container or
In hole filled with sand or other sound attenuating materials, then produced noise can be completely eliminated.
Certainly, in spite of the principle of the present invention, but embodiment and specific embodiment can with purely by non-limiting
Mode described and illustrated in example differs widely, without the model of the invention therefore limited beyond appended claims
Enclose.
