Description

本発明は、複数の板バネを用いるバネ装置に関するものである。   The present invention relates to a spring device using a plurality of leaf springs.

従来、この種のバネ装置としては、例えば、スターリングサイクル機関のケーシングに設けられた振動吸収ユニット等が知られている(例えば、特許文献1参照。)。この振動吸収ユニットは、複数の板バネを重ね、この重ねられた板バネにバランスウエイトをビス止め等によって固定することで構成されている。
特開2004−251180号公報
Conventionally, as this type of spring device, for example, a vibration absorbing unit provided in a casing of a Stirling cycle engine is known (for example, see Patent Document 1). This vibration absorbing unit is configured by stacking a plurality of plate springs and fixing a balance weight to the stacked plate springs with screws or the like.
JP 2004-251180 A

このような複数の前記板バネを重ねて用いるバネ装置においては、前記板バネが撓んだ際に、前記腕部同士が擦れることで摩擦音が生じたり、摩耗したりする虞があった。そして、このように前記各板バネの腕部同士が擦れることで、これらの腕部がスムーズに弾性変形できないという虞もあった。このため、複数の前記板バネを重ねて用いる従来のバネ装置では、図6に示すように、外周部102と中央部103と腕部104とを有する前記各板バネ101において、前記腕部104が弾性変形する際に、前記腕部104同士が接触することを防ぐ目的で、前記外周部102及び中央部103で前記各板バネ101同士の間にワッシャ105等のスペーサを挟んでいた。しかしながら、このように前記板バネ101同士の間に前記ワッシャ105を挟むと、これらのワッシャ105の厚み分、バネ装置100の厚さが増してしまうという問題があった。(前記板バネ101の厚さをTs、前記ワッシャ105の厚さをTw、前記板バネ101の枚数をnとすると、前記バネ装置100の厚さTaはnTs+(n−1)Twとなる。(なお、ビス106及びバランスウエイト107の寸法は含まないものとする。))このような前記バネ装置100の厚さの増加は、使用する前記板バネ101の枚数が少ない場合にはさほど問題とならないが、使用する前記板バネ101の枚数が多くなるに従って無視できない厚さ増となる。また、ワッシャ105自体の単価はそれほど大きくないものの、前記板バネ101の枚数が多くなるに従って前記ワッシャ105の数も多くなり、これが組立工数の増加にも繋がってしまうので、原材料費及び組立工賃の両方で大幅な増加に繋がってしまう虞があった。   In such a spring device using a plurality of the leaf springs, there is a risk that when the leaf springs are bent, the arm portions rub against each other to generate frictional noise or wear. In addition, the arm portions of the plate springs rub against each other in this way, and there is a concern that these arm portions cannot be elastically deformed smoothly. For this reason, in the conventional spring device that uses a plurality of the leaf springs in an overlapping manner, as shown in FIG. 6, each of the leaf springs 101 having the outer peripheral portion 102, the central portion 103, and the arm portion 104, the arm portion 104. In order to prevent the arm portions 104 from coming into contact with each other during elastic deformation, a spacer such as a washer 105 is sandwiched between the leaf springs 101 at the outer peripheral portion 102 and the central portion 103. However, if the washer 105 is sandwiched between the plate springs 101 in this way, there is a problem that the thickness of the spring device 100 increases by the thickness of these washers 105. (If the thickness of the leaf spring 101 is Ts, the thickness of the washer 105 is Tw, and the number of leaf springs 101 is n, the thickness Ta of the spring device 100 is nTs + (n−1) Tw. (Note that the dimensions of the screw 106 and the balance weight 107 are not included.) The increase in the thickness of the spring device 100 is a problem when the number of the leaf springs 101 to be used is small. However, as the number of the leaf springs 101 used increases, the thickness increases not to be ignored. In addition, although the unit price of the washer 105 itself is not so large, the number of the washers 105 increases as the number of the leaf springs 101 increases, which leads to an increase in assembly man-hours. There was a risk that both would lead to a significant increase.

本発明は以上の問題点を解決し、多数の板バネを重ねたとしても腕部同士が接触せず、全体の厚さを薄くできると共に安価に製造できるバネ装置を提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide a spring device that solves the above-described problems and does not allow the arms to contact each other even when a large number of leaf springs are stacked, and that the overall thickness can be reduced and can be manufactured at low cost. .

本発明の請求項1に記載のバネ装置は、以上のように構成することにより、前記板バネの腕部が撓んだ際に、隣接する板バネの腕部間で撓むことになるので、ワッシャ等のスペーサを用いなくても、前記板バネの腕部が隣接する前記板バネの腕部と接しないようにすることができる。また、隣接しない他の前記板バネの腕部に対しては、隣接する前記板バネがスペーサの役割を果たすことで、前記板バネの腕部が他の前記板バネの腕部と接しないようにすることができる。 Since the spring device according to claim 1 of the present invention is configured as described above, when the arm portion of the leaf spring is bent, it is bent between the arm portions of adjacent leaf springs. Even without using a spacer such as a washer, the arm portion of the leaf spring can be prevented from coming into contact with the adjacent arm portion of the leaf spring. Further, with respect to the arm portion of the other of said plate spring which are not adjacent, next contacting the plate spring that serves as a spacer, so that the arm portion of the plate spring does not contact with the arm portion of the other of said plate spring Can be.

また、本発明の請求項2に記載のバネ装置は、以上のように構成することにより、前記板バネの貫通孔と隣接する前記板バネの異なる貫通孔を合わせて重ねることで、隣接する前記板バネ同士の腕部の位置をずらすことができるばかりでなく、前記貫通孔を用いて複数の前記板バネ同士の位置関係を固定することができる。   Moreover, the spring device according to claim 2 of the present invention is configured as described above, so that the adjacent through holes of the leaf springs and the different through holes of the leaf springs adjacent to each other are overlapped. Not only can the positions of the arm portions between the leaf springs be shifted, but also the positional relationship between the plurality of leaf springs can be fixed using the through holes.

更に、本発明の請求項4に記載のバネ装置は、以上のように構成することにより、前記切欠部をガイドして前記板バネの切欠部を他の前記板バネの他の切欠部と合わせて重ねることで、隣接する前記板バネ同士の腕部の位置をずらすことができるばかりでなく、前記貫通孔の数が前記切欠部の数の倍数であることで、前記板バネの貫通孔と他の前記板バネの貫通孔の位置を合わせることができる。   Furthermore, the spring device according to claim 4 of the present invention is configured as described above, thereby guiding the notch and aligning the notch of the leaf spring with another notch of the other leaf spring. In addition to being able to shift the position of the arm portions of the adjacent leaf springs, the number of the through holes is a multiple of the number of the notches, The positions of the other through holes of the leaf springs can be matched.

以下、本発明の実施形態について、図1乃至図5に基づいて説明する。1はスターリング冷凍機である。このスターリング冷凍機1は、スターリング冷凍機本体2と、このスターリング冷凍機本体2に取り付けられた取付部3と、この取付部3に取り付けられたバネ装置としての振動吸収ユニット4とを有して構成されている。そして、前記振動吸収ユニット4は、複数の板バネ5と、これらの板バネ5に対してビス6等によって固定されたバランスウエイト7とで構成されている。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 5. Reference numeral 1 denotes a Stirling refrigerator. This Stirling refrigerator 1 has a Stirling refrigerator main body 2, a mounting portion 3 attached to the Stirling refrigerator main body 2, and a vibration absorbing unit 4 as a spring device attached to the mounting portion 3. It is configured. The vibration absorbing unit 4 includes a plurality of leaf springs 5 and a balance weight 7 fixed to these leaf springs 5 with screws 6 or the like.

前記板バネ5は、略円形に形成された外周部8と、この外周部8と同心に設けられた中央部9と、これら外周部8と中央部9とを接続する複数(本実施形態では3本)の腕部10とを有して一体に構成されている。なお、複数の前記腕部10は等角度間隔(本実施形態では120度間隔)で設けられていると共に、渦巻き状に形成されている。また、前記腕部10自体の太さXは、前記腕部10同士の間隔Yよりも細くなるように形成されている。そして、前記外周部8には、複数(本実施形態では6個所)の貫通孔11が等角度間隔(本実施形態では60度間隔)で形成されており、この貫通孔11を用いて前記板バネ5とバランスウエイト7を前記ビス6等によって螺子止めすることができるようになっている。また、前記外周部8には、複数(本実施形態では2個所)の切欠部12が等角度間隔(本実施形態では180度間隔)で形成されている。そして、前記中央部9には、中央貫通孔13と、この中央貫通孔13を囲むように複数(本実施形態では6個所)の貫通孔14が等角度間隔(本実施形態では60度間隔)で形成されている。そして、前記板バネ5は、前記貫通孔14を用いて図示しないビス等によって前記取付部3に螺子止めすることができるようになっている。   The leaf spring 5 has an outer peripheral portion 8 formed in a substantially circular shape, a central portion 9 provided concentrically with the outer peripheral portion 8, and a plurality of (in this embodiment) connecting the outer peripheral portion 8 and the central portion 9. And three arm portions 10 are integrally formed. The plurality of arm portions 10 are provided at equiangular intervals (in the present embodiment, 120 ° intervals) and are formed in a spiral shape. Further, the thickness X of the arm portion 10 itself is formed to be smaller than the interval Y between the arm portions 10. A plurality (six in this embodiment) of through holes 11 are formed in the outer peripheral portion 8 at equiangular intervals (60 degrees in the present embodiment). The spring 5 and the balance weight 7 can be screwed with the screw 6 or the like. In addition, a plurality (two in this embodiment) of notches 12 are formed in the outer peripheral portion 8 at equiangular intervals (180 degrees in this embodiment). The central portion 9 has a central through hole 13 and a plurality of (six in this embodiment) through holes 14 surrounding the central through hole 13 at equiangular intervals (60 degrees in this embodiment). It is formed with. The leaf spring 5 can be screwed to the mounting portion 3 with a screw or the like (not shown) using the through hole 14.

なお、前記板バネ5は、前記振動吸収ユニット4だけでなく、前記スターリング冷凍機本体2の内部で使用することができるように形成されている。例えば、前記板バネ5には前記切欠部12が形成されているが、この切欠部12は、前記スターリング冷凍機本体2内において、図示しない配線を通すために用いられる。また、前記板バネ5には前記中央貫通孔13が形成されているが、この前記中央貫通孔13は、前記スターリング冷凍機本体2内において、図示しないディスプレイサーロッドを通すために用いられる。   The leaf spring 5 is formed so that it can be used not only in the vibration absorbing unit 4 but also in the Stirling refrigerator main body 2. For example, the cutout portion 12 is formed in the leaf spring 5, and the cutout portion 12 is used in the Stirling refrigerator main body 2 for passing a wiring (not shown). The leaf spring 5 is formed with the central through-hole 13, and the central through-hole 13 is used in the Stirling refrigerator main body 2 for passing a display cirrod (not shown).

そして、図3に示すように、前記板バネ5の一方の切欠部12A及び他方の切欠部12Bが、それぞれ隣り合う前記板バネ5の他方の切欠部12B及び一方の切欠部12Aと重なるように、複数の前記板バネ5は、これらの板バネ5の中央を通る軸Z回りに180度ずつずらして重ねられる。なお、この際、前記複数の板バネ5同士の間には、ワッシャ等のスペーサは設けられない。従って、バネ装置としての前記振動吸収ユニット4の厚さTaは、前記ビス6とバランスウエイト7の寸法を除けば、前記板バネ5の厚さをTs、前記板バネ5の枚数をnとすると、nTsとなり、従来の構造に比べてワッシャn−1枚分((n−1)Tw)薄くすることができる。また、複数の前記板バネ5を、従来の構造のように、間にワッシャを挟んで積層すると、前記板バネ5の場合、前記貫通孔11が前記板バネ5一枚当たり6個所形成されているので、必要なワッシャの枚数は6(n−1)枚となってしまい、前記板バネ5の枚数が増えると、原材料費及び組立工賃が増加してしまうばかりでなく、前記中央部9においては、一般的な形状のワッシャを使用することができず、特殊な形状のスペーサ或いは特殊な径のワッシャを用いる必要があるので、ここでも原材料費及び組立工賃が増加してしまう虞がある。しかしながら、本発明のバネ装置としての振動吸収ユニット4では、このようなワッシャ或いは特殊なスペーサを用いる必要がないので、ワッシャ或いは特殊なスペーサを用いる場合の原材料費及び組立工賃が不要となり、従来の構造に比べて大幅なコストダウンが可能となる。   Then, as shown in FIG. 3, one notch 12A and the other notch 12B of the leaf spring 5 overlap with the other notch 12B and one notch 12A of the adjacent leaf spring 5, respectively. The plurality of leaf springs 5 are stacked with a shift of 180 degrees around the axis Z passing through the center of the leaf springs 5. At this time, a spacer such as a washer is not provided between the plurality of leaf springs 5. Therefore, the thickness Ta of the vibration absorbing unit 4 as a spring device is determined by assuming that the thickness of the leaf spring 5 is Ts and the number of the leaf springs 5 is n, excluding the dimensions of the screw 6 and the balance weight 7. , NTs, and can be made thinner by (n-1) Tw washers than the conventional structure. Further, when a plurality of the plate springs 5 are stacked with a washer interposed therebetween as in the conventional structure, in the case of the plate springs 5, six through holes 11 are formed per one plate spring 5. Therefore, the number of necessary washers is 6 (n-1). When the number of the leaf springs 5 is increased, not only the raw material cost and the assembly labor cost are increased, but also in the central portion 9. However, it is not possible to use a washer having a general shape, and it is necessary to use a spacer having a special shape or a washer having a special diameter. Therefore, there is a possibility that the raw material cost and the assembly labor cost may increase here. However, in the vibration absorbing unit 4 as the spring device of the present invention, since it is not necessary to use such a washer or a special spacer, the raw material cost and assembly cost when using the washer or the special spacer are not required. Compared to the structure, the cost can be greatly reduced.

また、このように複数の前記板バネ5を重ねる際、前記切欠部12に対応する図示しないガイドを用いて前記板バネ5を重ねてゆけば、前記板バネ5同士の位置合わせを簡単に行うことができる。そして、このように前記板バネ5を重ねた場合、前記貫通孔11が60度間隔で6個所、即ち180度間隔で2個所形成された前記切欠部12の倍数形成されているため、前記板バネ5同士が軸Z回りに180度ずつずれていたとしても、貫通孔11A,11B,11C,11D,11E,11Fが、それぞれ隣り合う前記板バネ5の貫通孔11D,11E,11F,11A,11B,11Cと重なることになる。同様に、貫通孔14A,14B,14C,14D,14E,14Fも、それぞれ隣り合う前記板バネ5の貫通孔14D,14E,14F,14A,14B,14Cと重なることになる。従って、前記板バネ5を軸Z回りに180度ずつずらして重ねたとしても、前記貫通孔11,14でビス止めが可能となる。   Further, when the plurality of plate springs 5 are stacked in this way, if the plate springs 5 are stacked using a guide (not shown) corresponding to the notch portion 12, the plate springs 5 can be easily aligned with each other. be able to. And when the said leaf | plate spring 5 is piled up in this way, since the said through-hole 11 is formed in multiples of the said notch part 12 formed in six places at 60 degree intervals, ie, two places in 180 degree intervals, Even if the springs 5 are shifted by 180 degrees around the axis Z, the through holes 11A, 11B, 11C, 11D, 11E, and 11F are respectively connected to the through holes 11D, 11E, 11F, 11A, and 11B and 11C overlap. Similarly, the through holes 14A, 14B, 14C, 14D, 14E, and 14F also overlap with the through holes 14D, 14E, 14F, 14A, 14B, and 14C of the adjacent leaf springs 5, respectively. Therefore, even if the leaf springs 5 are shifted by 180 degrees around the axis Z and overlapped, the through holes 11 and 14 can be screwed.

また、このように前記板バネ5を重ねた場合、腕部10A,10B,10Cが、それぞれ隣り合う前記板バネ5の腕部10B−10C間の中央、10C−10A間の中央、10A−10B間の中央に位置することになる。従って、このように重ねられた複数の前記板バネ5は、図4に示すように、軸Z方向から見て、60度間隔で腕部10が配されることになる。そして、この際、前記板バネ5は、隣接する前記板バネ5に対してスペーサの役割を果たすことになる。即ち、図3における中央の前記板バネ5が上下の前記板バネ5に対してスペーサの役割を果たすことで、これらの板バネ5が撓む際に、上下の前記板バネ5同士の腕部10が接触することを防止することができる。同様に、上下の前記板バネ5も、それらの更に上下隣の前記板バネ5と中央の板バネ5に対してスペーサの役割を果たすことになる。また、前述したように、前記腕部10A,10B,10Cが、それぞれ隣り合う板バネ5の前記腕部10B−10C間の中央、10C−10A間の中央、10A−10B間の中央に位置することで、前記板バネ5の腕部10と隣接する前記板バネ5の腕部10との間隔を充分に確保することができるので、前記腕部10同士の接触を確実に防ぐことができる。   Further, when the leaf springs 5 are overlapped in this way, the arm portions 10A, 10B, and 10C are respectively located at the center between the arm portions 10B-10C of the adjacent leaf springs 5, the center between 10C-10A, 10A-10B. It will be located in the middle. Therefore, as shown in FIG. 4, the plurality of leaf springs 5 stacked in this way are provided with the arm portions 10 at intervals of 60 degrees as viewed from the axis Z direction. At this time, the leaf spring 5 serves as a spacer with respect to the adjacent leaf spring 5. That is, when the leaf springs 5 at the center in FIG. 3 serve as spacers with respect to the upper and lower leaf springs 5, when these leaf springs 5 are bent, the arm portions between the upper and lower leaf springs 5. It can prevent that 10 contacts. Similarly, the upper and lower leaf springs 5 also serve as spacers for the leaf springs 5 adjacent to the upper and lower sides and the central leaf spring 5. Further, as described above, the arm portions 10A, 10B, and 10C are located at the center between the arm portions 10B-10C of the adjacent leaf springs 5, the center between 10C-10A, and the center between 10A-10B. As a result, a sufficient distance between the arm portion 10 of the leaf spring 5 and the adjacent arm portion 10 of the leaf spring 5 can be ensured, so that contact between the arm portions 10 can be reliably prevented.

なお、前記腕部10の数A、前記ビス孔11の数B、前記切欠部12の数C、前記ビス孔14の数Dの条件は、AとCが異なる数であり、また、B及びDがCと等しいか又はその倍数である。そして、Aが奇数であり、Cが偶数であり、B及びDがAの偶数倍になることがより好ましい。本実施形態の場合、Aは3であり、Cは2であり、B及びDはそれぞれAの偶数倍で且つCの倍数の6である。   The conditions of the number A of the arm portions 10, the number B of the screw holes 11, the number C of the notches 12, and the number D of the screw holes 14 are different numbers for A and C, and B and D is equal to or a multiple of C. More preferably, A is an odd number, C is an even number, and B and D are an even multiple of A. In this embodiment, A is 3, C is 2, and B and D are even multiples of A and 6 multiples of C, respectively.

以上のように本発明は、外周部8と中央部9とこれらを接続する複数の腕部10とを有して一体に構成される同形状の板バネ5を複数重ねてバネ装置としての振動吸収ユニット4を構成し、前記板バネ5の腕部10の太さXをこれらの腕部10同士の間隔Yよりも細く形成すると共に、複数の前記板バネ5を、隣接する前記板バネ5の腕部10同士が干渉しないように、振幅方向となる軸Z回りに互いにずらして重ねることで、前記板バネ5の腕部10が撓んだ際に、隣接する前記板バネ5の腕部10間で撓むことになるので、スペーサを用いることなく前記板バネ5の腕部10が隣接する前記板バネ5の腕部10と接しないようにすることができるばかりでなく、隣接しない他の前記板バネ5の腕部10に対しては、隣接する前記板バネ5がスペーサの役割を果たして前記板バネ5の腕部10が他の前記板バネ5の腕部10と接しないようにすることができるものである。 As described above, according to the present invention, vibration as a spring device is obtained by stacking a plurality of identically shaped leaf springs 5 having an outer peripheral portion 8, a central portion 9, and a plurality of arm portions 10 connecting them. The absorption unit 4 is configured, and the thickness X of the arm portion 10 of the plate spring 5 is formed to be narrower than the interval Y between the arm portions 10, and a plurality of the plate springs 5 are arranged adjacent to each other. The arm portions of the adjacent leaf springs 5 when the arm portions 10 of the leaf springs 5 are bent by overlapping each other around the axis Z in the amplitude direction so that the arm portions 10 do not interfere with each other. 10, the arm portion 10 of the leaf spring 5 can be prevented from contacting the adjacent arm portion 10 of the leaf spring 5 without using a spacer. against the arm portion 10 of the plate spring 5, adjacent contacts the plate spring 5 It is capable to arms 10 of the leaf spring 5 serve spacer so as not to contact with the arm portion 10 of the other of the plate spring 5.

また、本発明は、前記板バネ5の複数の腕部10を120度の等角度間隔で設けると共に、前記板バネ5の外周部8に複数の貫通孔11を60度の等角度間隔で設けたことで、前記板バネ5の貫通孔11と隣接する前記板バネ5の異なる貫通孔11を合わせて重ねることで、隣接する前記板バネ5同士の腕部10の位置をずらすことができるばかりでなく、前記貫通孔11を用いて複数の前記板バネ5同士の位置関係をビス止め等で固定することができるものである。また、前記貫通孔11の数を前記腕部10の数の2倍としたことで、前記板バネ5の腕部10が、隣接する前記板バネ5の腕部10同士の間の丁度中央に配されるので、前記板バネ5の腕部10と隣接する前記板バネ5の腕部10との間隔を充分に確保して、前記腕部10同士の接触を確実に防ぐことができるものである。   In the present invention, the plurality of arm portions 10 of the plate spring 5 are provided at equal angular intervals of 120 degrees, and the plurality of through holes 11 are provided at the outer peripheral portion 8 of the plate spring 5 at equal angular intervals of 60 degrees. As a result, the through holes 11 of the leaf springs 5 and the different through holes 11 of the leaf springs 5 adjacent to each other can be overlapped so that the positions of the arm portions 10 between the adjacent leaf springs 5 can be shifted.
