Summary of the invention
But, in recent years, require further to improve the travelling speed of parts, thereby the driving frequency of Piezoelectric Driving body uprises and amplitude increases, so big to the driving load of Piezoelectric Driving body, Piezoelectric Driving body durability goes wrong.And then, in above-mentioned horizontal rotational vibrations machine, be fixed under the state on the vibrating disk and move transporting body to the for example bowl formula of oscillatory type conveyer; But; As above-mentioned, require high-frequency and amplitude big, so, when making the perseveration of rotational vibrations machine; Sometimes at vibrating disk and transport and produce the gap between the body, or make vibrating disk and transport the noise that produces between body and become big.
The present invention can address the above problem, and the requirement that the corresponding high speed in recent years of ability is transported realizes high efficiency and the high rotational vibrations machine of durability.
In view of these actual conditions, what time following the result of inventor of the present invention through studying with keen determination found.Promptly; Piezoelectric Driving body and elastomeric element from the central side of pedestal to the rotational vibrations machine of the form that outer circumferential side radially extends; Because in fact the deflection deformation through the Piezoelectric Driving body is tangentially vibrated vibrating disk; So; Not being that the tie point of the starting of oscillation mechanism that is made up of Piezoelectric Driving body and elastomeric element and vibrating disk is vibrated around the center of pedestal, is that center vibrate with the center from pedestal to the position (the for example centre position radially of Piezoelectric Driving body) that radial outside staggers but make it.The loss that therefore, can produce actuating force because of the skew of the vibrational state of the vibrational state of starting of oscillation mechanism and vibrating disk.In addition; When producing the double vibrations of tangential direction, the Piezoelectric Driving body receives tensile stress radially from vibrating disk, and vibrating disk is compressed stress to the inside from starting of oscillation mechanism radius vector; So; Can that the durability of Piezoelectric Driving body reduce to be produced be damaged because of above-mentioned stress, or since the occasion vibrating disk that reduces in the rigidity of vibrating disk deform, and as time passes at vibrating disk and transport on the stationary plane of body and produce the gap, make vibrating disk and transport and produce noise between body.
In order to solve above-mentioned some problem; The mechanism of the present invention's explaination does; A kind of rotational vibrations machine; Said rotational vibrations facility have: pedestal, be configured in this pedestal top vibrating disk, have the interior perimembranous that is being connected with this pedestal directly or indirectly and perimembranous is extended to radial outside in this Piezoelectric Driving body and be connected the peripheral part of this Piezoelectric Driving body and the elastomeric element between said vibrating disk; It is characterized in that: said elastomeric element is the plate-like piece that in from interior all side connecting portions of being connected with the peripheral part side of said Piezoelectric Driving body to the scope of the outer circumferential side connecting portion that is being connected with said vibrating disk side, radially extends and have tangentially crooked shape.According to the present invention, elastomeric element is radially to extend and to the plate-like piece of the crooked shape of tangential direction, thus, this elastomeric element can easily stretch under the state of the curved shape that changes tangential direction diametrically.Therefore, can alleviate the center of central point and pedestal and vibrating disk of vibrational state of tangential direction of above-mentioned starting of oscillation mechanism inconsistent that cause, when action, be applied to the stress radially on Piezoelectric Driving body and the vibrating disk.So, owing to can alleviate the driving load that the Piezoelectric Driving body receives, and can improve the durability of Piezoelectric Driving body, and can suppress the distortion of vibrating disk.
In a mode of the present invention; In said elastomeric element; All side connecting portions and said outer circumferential side connecting portion radially extend together in said; In said, between all side connecting portions and outer circumferential side connecting portion, be provided with and radially extend afterwards to tangential direction one lateral bending song, the bent intermediate portion of after the bending of tangential direction opposition side, radially extending once more then.Thus because interior all side connecting portions and outer circumferential side connecting portion radially extending, and can be the actuating force of Piezoelectric Driving body generation with respect to vibrating disk to correctly applying with the tangential direction of quadrature radially, thereby vibrating disk is more effectively vibrated.In addition because bent intermediate portion is by constituting to the crooked simple shape of tangential direction opposition side to tangential direction one lateral bending song after, thereby transfer of vibration efficient and less reduction just can obtain retractility radially.
In other type of the present invention; Interior all side connecting portions of the peripheral part of said Piezoelectric Driving body and said elastomeric element are fixed under the state that tangentially overlaps; The said outer circumferential side connecting portion of said elastomeric element; Through to the crooked shape of said tangential direction, be configured in said that side of Piezoelectric Driving body when more leaning on tangential direction to observe than all side connecting portions in said.Thus; Interior all side connecting portions of the peripheral part of Piezoelectric Driving body and elastomeric element are connected with the state that overlaps in tangential direction; And the offset that makes tangential direction can be by the bending of elastomeric element shape and be able to revise to the direction that is lowered; Thereby the bearing of trend of the driving mechanism that is made up of Piezoelectric Driving body and elastomeric element on the whole can be set to from the radial deflection less state, so can be delivered to vibrating disk to actuating force effectively.
In this occasion, be preferably, the outer circumferential side connecting portion of said elastomeric element radially extends on the extended line of said Piezoelectric Driving body.The actuating force that can produce the Piezoelectric Driving body thus, is really and effectively to being delivered to vibrating disk with the tangential direction of quadrature radially.
In the other type of the present invention, said elastomeric element is provided with in both sides up and down and constitutes the outer rim of sag vertical curve shape respectively.Thus; The outer rim of two examples up and down of elastomeric element is constituted as the sag vertical curve shape; Thereby; Not only can improve torsional direction flexible of elastomeric element, and, can distribute through the modulus of rigidity of middle body step-down the stress of the outer rim of the both sides up and down that be applied to elastomeric element along curve to radially disperseing.Therefore; Even the deflection deformation of Piezoelectric Driving body makes elastomeric element when tangential direction is vibrated; The center of gravity of vibrating disk is in the top and on elastomeric element, applies distorting stress, also can stress disperseed, stop in the total length radially of elastomeric element to the torsional direction distortion through elastomeric element integral body.Therefore; For example locate, can prevent the damage that stress raisers cause at the boudary portion of interior all side connecting portions of the elastomeric element of the peripheral part that is fixed on the Piezoelectric Driving body or the boudary portion etc. that is fixed on the outer circumferential side connecting portion of the elastomeric element on the vibrating disk.

Fig. 6 (a) is the vertical view of elastomeric element 15, and Fig. 6 (b) is the side view of elastomeric element 15.At this, above-mentioned in all side connecting portion 15a be constituted as tabular, be formed with the through hole 15t that is used for inserting logical bolt.In addition, above-mentioned outer circumferential side connecting portion 15b also is formed tabular, is formed with the through hole 15u that is used for inserting logical bolt.In all side connecting portion 15a and outer circumferential side connecting portion 15b all constitute the band shape that broad ways (above-below direction among the figure) prolongs.In the embodiment illustrated, corresponding to the width of the peripheral part 14b of Piezoelectric Driving body 14 and vibrating disk 12 by the width up and down of connecting portion 12a, be configured the width of interior all side connecting portion 15a bigger than the width of outer circumferential side connecting portion 15b.
The 15c of bent intermediate portion has as above-mentioned to the crooked shape of tangential direction; When Width is observed; Outer rim 15d, the 15e of Width both sides (illustrated upper and lower sides) is formed sag vertical curve shape (concave arc shape) respectively; Be constituted as thus, width is all narrower than interior all side connecting portion 15a and outer circumferential side connecting portion 15b's.And, make the distribution of the modulus of rigidity radially (shearing elasticity coefficient) of elastomeric element 15 by outer rim 15d, the 15e of these sag vertical curve shapes, in that radially central portion is minimum, and along with becoming greatly gradually with outer circumferential side connecting portion 15b towards interior all side connecting portion 15a.
The radial distribution of the modulus of rigidity through above-mentioned that kind; Can effectively avoid the stress of the torsional direction that elastomeric element 15 receives from Piezoelectric Driving body 14 and vibrating disk 12; By concentrate affact above-mentioned in all side connecting portion 15a and the 15c of bent intermediate portion boundary line 15ac (for example; With the part that is used for connecting with the ora terminalis of the packing ring that is connected fixed part of Piezoelectric Driving body 14), the boundary line 15bc of above-mentioned outer circumferential side connecting portion 15b and the 15c of bent intermediate portion (for example, with the part that is used for connecting) with the ora terminalis of the packing ring that is connected fixed part of vibrating disk 12.The stress of above-mentioned torsional direction, be center of gravity that the center of gravity of fixing radially the pedestal 11 of the starting of oscillation mechanism 13 of extending is configured in the vibrating disk 12 that below, starting of oscillation mechanism 13 the drive structure that is configured in the top will inevitably produce.
Promptly; For example; Under the radially changeless situation of the width of elastomeric element 15, when receiving the stress of above-mentioned torsional direction, sometimes the last generation of above-mentioned boundary line 15ac, 15bc stress concentrate and crack in the Width end of these boundary lines, the damage of abrasion etc.But; In this execution mode; Bent intermediate portion 15c place is constituted as; Width is along with 15ac, 15bc break away from and narrow down, reduce modulus of rigidity towards radially centre position from the boundary line, and therefore, the deflection that is produced by the stress of above-mentioned torsional direction is along with 15ac, 15bc disengaging and increase from the boundary line.Therefore, can bear the stress of above-mentioned torsional direction through the bulk deformation radially of elastomeric element 15, so, be difficult to stress and concentrate and cause damage etc.In addition, because outer rim 15d, the 15e of elastomeric element 15 are formed the sag vertical curve shape, so further improved the dispersiveness of the stress of above-mentioned torsional direction along outer rim.
Though the outer rim 15d of above-mentioned sag vertical curve shape, 15e reduce the rigidity of tangential direction of the middle part of the 15c of bent intermediate portion,, the reduction of said rigidity is suppressed towards the curved shape of tangential direction by the above-mentioned bent intermediate 15c of portion.Therefore, in this execution mode, have the rigidity reduction of the tangential direction that can not only suppress elastomeric element 15 and can enjoy the such advantage of effect by the outer rim form generation of above-mentioned sag vertical curve shape.
In this execution mode; As above-mentioned; Elastomeric element 15 is crooked in tangential direction; Thereby radially stretching easily, therefore, can absorb vibrational state because of starting of oscillation mechanism 13 and be not with axis 10x is that the stress radially that reciprocal rotational motion produces is carried out at the center between starting of oscillation mechanism 13 and vibrating disk 12.
That is,, just can not produce above-mentioned stress so long as the vibrational state of the peripheral part of starting of oscillation mechanism 13 is to be that reciprocal rotational motion is carried out at the center with axis 10x; Yet practical problem is that on the physical method, it is very difficult being configured in the interior Zhou Duan of vibration generator 13 on the axis 10x; And; Even if can be configured in Zhou Duan in this on axis 10x, in fact above-mentioned vibrational state can produce bending vibration through Piezoelectric Driving body 14 and obtain, thereby; Under most occasions, the central point of this vibrational state can arrive the centre position radially of Piezoelectric Driving body.Therefore; In any case; The radius of the vibrational state of the outer circumferential side connecting portion 15b of elastomeric element 15; Less than vibrating disk 12 by the distance of connecting portion 12a and axis 10x, so the amplitude of the tangential direction of elastomeric element 15 is bigger, the radial stress of starting of oscillation mechanism 13 and 12 generations of vibrating disk is also just big more.
Above-mentioned stress increases the mechanical load radially of giving Piezoelectric Driving body 14, becomes the cause of Piezoelectric Driving body 14 breakages and has reduced durability.And, can on vibrating disk 12, cause stress deformation, for example, make to after state transport the supporting surface 12s distortion that body carries out the vibrating disk 12 of support fixation.The distortion of said supporting surface 12s can make and transport body and crook, and, produce the gap and reduce vibration efficiency transporting 12 of body and vibrating disks, and then, the noise of abutment portion from the two is increased.
In this execution mode, have curved shape through making above-mentioned elastomeric element 15, thereby can alleviate above-mentioned stress radially, thereby, the mechanical load radially that is applied on the Piezoelectric Driving body 14 and the distortion of vibrating disk 12 can be reduced.Therefore, can realize preventing Piezoelectric Driving body 14 breakage, improve durability, the lightweight of vibrating disk 12, its anti-noise, minimizing and transport the crooking of body, improve from vibrating disk to the vibration transfer efficient of transporting body etc.
