On the outer surface of cylindrical ring 17c, and cast or injection be formed in the gap between the bobbin and outer ring 17b, so as to
(the Fig. 3 to Fig. 6) of closed circle structure 19 is formed in component.
Then, the stator 7 being thusly-formed for example is attached to the support of accumulator using screw 20 and relevant casing 21
The rear wall 3f of the half-shell 3 of shell, the latter are preferably made of elastic material (referring also to Fig. 3).
With specific reference to Figure 14 to Figure 18, each support equipment 10 of the end 9a for axis 9 has (specific by Heat Conduction Material
For be metal) made of inner annular supporting element 30, wherein form substantially cylindrical seat 30a, the phase for the axis 9
Close end.
In the embodiment shown in (referring specifically to Figure 16), there is inner annular supporting element 30 edge to be arranged essentially parallel to cylinder
The gap 30b that the direction of the axis of shape seat 30a extends.Gap 30b make inner annular supporting element 30 formed it is adjacent to each other but
Separated Liang Ge branch or two bifurcateds 30c and 30d.
The inner annular supporting element 30 of each support equipment 10 is inserted into matching seat 31a, and the matching seat 31a is formed in
In the outer support members 31 be conveniently fabricated by elastic material (such as elastomer).
In an illustrated embodiment, the shape of inner annular supporting element 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 shape 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 supporting element 30, extend through corresponding recess portion 31b, and the recess portion 31b is formed
In the top side of the seat 31a of corresponding outer support members 31 made of elastic material.
When assembling accumulator 1, the rear wall of the half-shell 3 and 4 of the heat transfer member 33,34 and support housing 2 of support equipment 10
Be in close contact so that by gyrating mass 11 and axis 9 operation when generated heat be easy to pass through the heat transfer member 33,34
It is transferred to support housing 2, is subsequently dispersed in the environment of surrounding.
If Figure 16 and Figure 17 are more clearly shown, formed in the lower horizontal branch 31c of each outer support members 31
Substantially vertical through-hole 31d.The bar 35 made of rigid material (such as metal) be placed in the through-hole 31d (referring also to
Figure 14 and Figure 15).
If Figure 15 is specifically shown, the upper end of each rigid rod 35 is separated by towards relevant supporting element 30 and perpendicularly thereto
Preset distance.
Bar 35 is advantageously used for stopping element, under the action of axis 9 and gyrating mass 11 whole weight, is flexibly supporting
In the curved situation of component 31, supporting element 30 is easy to collide on stopping element.
In fact, determining that the length of rigid rod 35 makes even if after the bending of spring support member 31, accumulator 1 is in office
What also can acceptably 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
When energy device 1, the axis of axis 9 and related gyrating mass 11 extends higher than optimal design high perpendicular, this allows at least portion
Divide ground pre-compensation due to (the specifically lower horizontal point of spring support member 31 under the action of the weight being applied to it
Branch) continuous bending and lead to subsequent " decline " of the component.
Easily, (such as the permanent magnetism of rotor 11-13 is able to detect for sensing the device of the rotation speed of gyrating mass 11
Three passed through the hall effect sensor of body 43) (Fig. 1 and Fig. 2) is can be assembled in connection component 8.
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.
The end for being located towards the tubular element 40 of the bearing 13 has corresponding substantially upper conical surface
The half-shell 3 and 4 of 40a, the support housing far from accumulator are 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 at least partly extend in the outside of the bearing 13 of the opposite side of the end relative to tubular element 40.
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 being thus formed on the side of each bearing 13 make 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
Xiang Yu " centrifugation " operation.
In operation, accumulator according to the present invention generates low-intensity acoustic noise.If accumulator be mounted on container or
In hole filled with sand or other sound attenuating materials, then generated 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 therefore beyond model of the invention defined by the appended claims
It encloses.
