従来の偏心旋回駆動装置においては、特許文献１に示されるように、両面に突起が設けられたオルダムリングを有する自転防止装置を旋回軸とケーシングとの間に設けている。   In a conventional eccentric turning drive device, as shown in Patent Document 1, an anti-rotation device having an Oldham ring with protrusions on both sides is provided between a turning shaft and a casing.

特開昭２００１−１７８０７２号公報JP-A-2001-178072

しかし、このような偏心旋回駆動装置においては、自転防止装置の剛性が低いから、偏心旋回の精度が低く、また自転防止装置に過大な力が作用し、自転防止装置が損傷することがある。   However, in such an eccentric turning drive device, since the rotation prevention device has low rigidity, the accuracy of the eccentric turning is low, and an excessive force acts on the rotation prevention device, which may damage the rotation prevention device.

本発明は上述の課題を解決するためになされたもので、偏心旋回の精度が高く、また自転防止装置が損傷しにくい偏心旋回駆動装置を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an eccentric turning drive device that has high accuracy of eccentric turning and is difficult to damage the rotation prevention device.

この目的を達成するため、本発明においては、ケーシングと、上記ケーシングに固定されたステータと、上記ケーシングに回転可能に支持された回転軸と、上記回転軸に固定されたロータと、上記回転軸に偏心して回転可能に支持され旋回軸と、上記ケーシングに取り付けられた支持板と、上記支持板に回転可能に支持された回転板と、上記旋回軸に取り付けられた旋回板と、上記旋回板に固定されかつ上記回転板に対して回転可能に上記回転板に支持された連結軸とを設け、上記回転板の中心と上記連結軸の中心との距離を上記回転軸の中心と上記旋回軸の中心との距離と等しくする。   In order to achieve this object, in the present invention, a casing, a stator fixed to the casing, a rotating shaft rotatably supported by the casing, a rotor fixed to the rotating shaft, and the rotating shaft A pivot shaft that is eccentrically supported and rotatable, a support plate attached to the casing, a rotary plate rotatably supported on the support plate, a pivot plate attached to the pivot shaft, and the pivot plate A connecting shaft fixed to the rotating plate and supported by the rotating plate so as to be rotatable with respect to the rotating plate, and the distance between the center of the rotating plate and the center of the connecting shaft is set to the center of the rotating shaft and the pivot shaft. Is equal to the distance from the center.

また、ケーシングと、上記ケーシングに固定されたステータと、上記ケーシングに回転可能に支持された回転軸と、上記回転軸に固定されたロータと、上記回転軸に偏心して回転可能に支持され旋回軸と、上記ケーシングに取り付けられた支持板と、上記旋回軸に取り付けられた旋回板と、上記旋回板に回転可能に支持された回転板と、上記回転板に固定されかつ上記支持板に対して回転可能に上記支持板に支持された連結軸とを設け、上記回転板の中心と上記連結軸の中心との距離を上記回転軸の中心と上記旋回軸の中心との距離と等しくする。   A casing; a stator fixed to the casing; a rotating shaft rotatably supported on the casing; a rotor fixed to the rotating shaft; and a pivot shaft supported rotatably and eccentrically with respect to the rotating shaft. A supporting plate attached to the casing, a turning plate attached to the turning shaft, a rotating plate rotatably supported by the turning plate, and fixed to the rotating plate and with respect to the support plate A connecting shaft rotatably supported by the support plate is provided, and the distance between the center of the rotating plate and the center of the connecting shaft is made equal to the distance between the center of the rotating shaft and the center of the pivot shaft.

これらの場合、２枚の上記支持板の間に上記旋回板を位置させてもよい。   In these cases, the swivel plate may be positioned between the two support plates.

本発明に係る偏心旋回駆動装置においては、自転防止装置の剛性が高いから、偏心旋回の精度が高く、また自転防止装置に過大な力が作用することがないから、自転防止装置が損傷しにくい。   In the eccentric turning drive device according to the present invention, since the rotation prevention device has high rigidity, the accuracy of the eccentric rotation is high, and an excessive force does not act on the rotation prevention device, so that the rotation prevention device is not easily damaged. .

また、２枚の支持板の間に旋回板を位置させたときには、自転防止装置の剛性をさらに高くすることができるから、偏心旋回の精度をさらに高くすることができる。   Further, when the swivel plate is positioned between the two support plates, the rigidity of the rotation prevention device can be further increased, so that the accuracy of the eccentric swivel can be further increased.

図１は本発明に係る偏心旋回駆動装置を示す概略断面図、図２は図１のＡ−Ａ断面図、図３は図１のＢ−Ｂ断面図である。図に示すように、ケーシング１にステータ２が固定され、ケーシング１に軸受支え３、４が固定され、軸受支え３、４に軸受５、６を介して回転軸７が回転可能に支持されている。すなわち、ケーシング１に回転軸７が回転可能に支持されている。また、回転軸７にロータ８が固定され、ステータ２、ロータ８等によりモータが構成されている。また、回転軸７に軸受９、１０を介して旋回軸１１が回転可能に支持され、回転軸７の中心線と旋回軸１１の中心線とは偏っている。すなわち、旋回軸１１は回転軸７に偏心して回転可能に支持されている。また、ケーシング１に２枚の支持板１２が取り付けられ、支持板１２に軸受１３を介して４枚の回転板１４が回転可能に支持され、支持板１２に穴１６が設けられ、穴１６を旋回軸１１が貫通している。また、旋回軸１１に旋回板１７が取り付けられ、旋回板１７は２枚の支持板１２の間に位置しており、旋回板１７の両面にそれぞれ４本の連結軸１８が固定され、連結軸１８は軸受１５を介して回転板１４に対して回転可能に回転板１４に支持されている。そして、回転板１４の中心と連結軸１８の中心との距離は回転軸７の中心と旋回軸１１の中心との距離と等しく、支持板１２、回転板１４、旋回板１７、連結軸１８等により旋回軸１１の偏心旋回を許容しかつ旋回軸１１の自転を防止する自転防止装置が構成されている。   1 is a schematic cross-sectional view showing an eccentric turning drive device according to the present invention, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. As shown in the figure, a stator 2 is fixed to a casing 1, bearing supports 3 and 4 are fixed to the casing 1, and a rotating shaft 7 is rotatably supported by the bearing supports 3 and 4 via bearings 5 and 6. Yes. That is, the rotating shaft 7 is rotatably supported by the casing 1. A rotor 8 is fixed to the rotating shaft 7, and a motor is constituted by the stator 2, the rotor 8, and the like. Further, the rotating shaft 11 is rotatably supported by the rotating shaft 7 through bearings 9 and 10, and the center line of the rotating shaft 7 and the center line of the rotating shaft 11 are deviated. That is, the turning shaft 11 is eccentrically supported by the rotating shaft 7 and is rotatably supported. Further, two support plates 12 are attached to the casing 1, and four rotary plates 14 are rotatably supported on the support plate 12 via bearings 13. A hole 16 is provided in the support plate 12. The turning shaft 11 passes therethrough. Further, a swivel plate 17 is attached to the swivel shaft 11, and the swivel plate 17 is located between the two support plates 12, and four connecting shafts 18 are fixed to both surfaces of the swivel plate 17, respectively. 18 is supported by the rotating plate 14 via a bearing 15 so as to be rotatable with respect to the rotating plate 14. The distance between the center of the rotating plate 14 and the center of the connecting shaft 18 is equal to the distance between the center of the rotating shaft 7 and the center of the turning shaft 11, and the support plate 12, the rotating plate 14, the turning plate 17, the connecting shaft 18, etc. Thus, an anti-rotation device that allows eccentric rotation of the turning shaft 11 and prevents rotation of the turning shaft 11 is configured.

図１〜図３に示した偏心旋回駆動装置においては、ステータ２の巻線に通電すると、ロータ８、回転軸７が回転し、旋回軸１１は回転軸７の中心線を中心として偏心旋回するが、回転板１４、連結軸１８等からなる自転防止装置が設けられているから、旋回軸１１は自転しない。このため、旋回軸１１がケーシング１に対して回転せずに偏心旋回する。   1 to 3, when the windings of the stator 2 are energized, the rotor 8 and the rotating shaft 7 rotate, and the rotating shaft 11 rotates eccentrically around the center line of the rotating shaft 7. However, since the rotation preventing device including the rotating plate 14 and the connecting shaft 18 is provided, the turning shaft 11 does not rotate. For this reason, the turning shaft 11 turns eccentrically without rotating with respect to the casing 1.

このような偏心旋回駆動装置においては、自転防止装置として支持板１２、回転板１４、旋回板１７、連結軸１８を有するものを用いているから、自転防止装置の剛性が高いので、偏心旋回の精度が高く、また自転防止装置に過大な力が作用することがなく、自転防止装置が損傷しにくい。また、２枚の支持板１２の間に旋回板１７を位置させているから、自転防止装置の剛性を非常に高くすることができるので、偏心旋回の精度を非常に高くすることができる。   In such an eccentric turning drive device, as the rotation preventing device, the one having the support plate 12, the rotating plate 14, the turning plate 17, and the connecting shaft 18 is used. Therefore, since the rotation preventing device has high rigidity, The accuracy is high, and an excessive force does not act on the rotation prevention device, so that the rotation prevention device is hardly damaged. Further, since the turning plate 17 is positioned between the two support plates 12, the rigidity of the rotation prevention device can be made extremely high, and therefore the accuracy of the eccentric turning can be made very high.

図４は本発明に係る他の偏心旋回駆動装置を示す概略断面図、図５は図４のＣ−Ｃ断面図、図６は図４のＤ−Ｄ断面図である。図に示すように、ケーシング１に２枚の支持板２１が取り付けられ、支持板２１に穴２３が設けられ、穴２３を旋回軸１１が貫通している。また、旋回軸１１に旋回板２４が取り付けられ、旋回板２４は２枚の支持板２１の間に位置しており、旋回板２４に軸受２５を介して４枚の回転板２６が回転可能に支持され、回転板２６の両面にそれぞれ４本の連結軸２７が固定され、連結軸２７は軸受２２を介して支持板２１に対して回転可能に支持板２１に支持されている。そして、回転板２６の中心と連結軸２７の中心との距離は回転軸７の中心と旋回軸１１の中心との距離と等しく、支持板２１、旋回板２４、回転板２６、連結軸２７等により旋回軸１１の偏心旋回を許容しかつ旋回軸１１の自転を防止する自転防止装置が構成されている。   4 is a schematic cross-sectional view showing another eccentric turning drive device according to the present invention, FIG. 5 is a cross-sectional view taken along the line CC in FIG. 4, and FIG. 6 is a cross-sectional view taken along the line DD in FIG. As shown in the figure, two support plates 21 are attached to the casing 1, a hole 23 is provided in the support plate 21, and the turning shaft 11 passes through the hole 23. Further, a swivel plate 24 is attached to the swivel shaft 11, and the swivel plate 24 is located between the two support plates 21, so that the four rotation plates 26 can rotate on the swivel plate 24 via bearings 25. Four connecting shafts 27 are fixed to both surfaces of the rotating plate 26, and the connecting shafts 27 are supported by the supporting plate 21 via bearings 22 so as to be rotatable with respect to the supporting plate 21. The distance between the center of the rotating plate 26 and the center of the connecting shaft 27 is equal to the distance between the center of the rotating shaft 7 and the center of the turning shaft 11, and the support plate 21, turning plate 24, rotating plate 26, connecting shaft 27, etc. Thus, an anti-rotation device that allows eccentric rotation of the turning shaft 11 and prevents rotation of the turning shaft 11 is configured.

図４〜図６に示した偏心旋回駆動装置においては、ステータ２の巻線に通電すると、ロータ８、回転軸７が回転し、旋回軸１１は回転軸７の中心線を中心として偏心旋回するが、回転板２６、連結軸２７等からなる自転防止装置が設けられているから、旋回軸１１は自転しない。このため、旋回軸１１がケーシング１に対して回転せずに偏心旋回する。   4 to 6, when the windings of the stator 2 are energized, the rotor 8 and the rotary shaft 7 rotate, and the rotary shaft 11 rotates eccentrically around the center line of the rotary shaft 7. However, since the rotation preventing device including the rotating plate 26, the connecting shaft 27 and the like is provided, the turning shaft 11 does not rotate. For this reason, the turning shaft 11 turns eccentrically without rotating with respect to the casing 1.

このような偏心旋回駆動装置においては、自転防止装置として支持板２１、旋回板２４、回転板２６、連結軸２７を有するものを用いているから、自転防止装置の剛性が高いので、偏心旋回の精度が高く、また自転防止装置に過大な力が作用することがなく、自転防止装置が損傷しにくい。また、２枚の支持板２１の間に旋回板２４を位置させているから、自転防止装置の剛性を非常に高くすることができるので、偏心旋回の精度を非常に高くすることができる。   In such an eccentric turning drive device, as the rotation preventing device, the one having the support plate 21, the turning plate 24, the rotating plate 26, and the connecting shaft 27 is used. The accuracy is high, and an excessive force does not act on the rotation prevention device, so that the rotation prevention device is hardly damaged. Further, since the turning plate 24 is positioned between the two support plates 21, the rigidity of the rotation prevention device can be made extremely high, and therefore the accuracy of eccentric turning can be made very high.

図７は本発明に係る他の偏心旋回駆動装置を有するスクロール流体機械の一部を示す概略断面図である。図に示すように、ケーシング１に１枚の支持板１２が取り付けられ、支持板１２に軸受１３を介して４枚の回転板１４が回転可能に支持され、支持板１２に穴１６が設けられ、穴１６を旋回軸１１が貫通している。また、旋回軸１１に旋回板１７が取り付けられ、旋回板１７の支持板１２に対向した面に４本の連結軸１８が固定され、連結軸１８は軸受１５を介して回転板１４に対して回転可能に回転板１４に支持されている。そして、回転板１４の中心と連結軸１８の中心との距離は回転軸７の中心と旋回軸１１の中心との距離と等しい。すなわち、支持板１２の構成は図１〜図３に示した偏心旋回駆動装置の支持板１２の構成と同様である。そして、支持板１２、回転板１４、旋回板１７、連結軸１８等により旋回軸１１の偏心旋回を許容しかつ旋回軸１１の自転を防止する自転防止装置が構成されている。また、旋回軸１１にスクロール流体機械本体の旋回スクロール３１が旋回軸１１の中心線方向にのみ移動可能に取り付けられ、旋回板１７に環状体３２が取り付けられ、旋回スクロール３１に環状体３３が取り付けられ、環状体３２の外周面と環状体３３の内周面とが移動可能にかつ気密に当接しており、旋回板１７、環状体３２、３３、旋回スクロール３１により圧力室３４が形成されている。また、旋回スクロール３１に通路３５が設けられ、通路３５はスクロール流体機械本体の固定スクロールと旋回スクロール３１との間に形成された圧縮室（図示せず）と圧力室３４とを連通している。   FIG. 7 is a schematic sectional view showing a part of a scroll fluid machine having another eccentric turning drive device according to the present invention. As shown in the figure, a single support plate 12 is attached to the casing 1, four rotary plates 14 are rotatably supported on the support plate 12 via bearings 13, and holes 16 are provided in the support plate 12. The pivot 11 passes through the hole 16. A swivel plate 17 is attached to the swivel shaft 11, and four connecting shafts 18 are fixed to the surface of the swivel plate 17 facing the support plate 12. The connecting shaft 18 is connected to the rotating plate 14 via a bearing 15. The rotating plate 14 is rotatably supported. The distance between the center of the rotating plate 14 and the center of the connecting shaft 18 is equal to the distance between the center of the rotating shaft 7 and the center of the turning shaft 11. That is, the configuration of the support plate 12 is the same as the configuration of the support plate 12 of the eccentric turning drive device shown in FIGS. The support plate 12, the rotating plate 14, the turning plate 17, the connecting shaft 18, and the like constitute a rotation prevention device that allows the turning shaft 11 to turn eccentrically and prevents the turning shaft 11 from rotating. Further, the orbiting scroll 31 of the scroll fluid machine main body is attached to the orbiting shaft 11 so as to be movable only in the direction of the center line of the orbiting shaft 11, the annular body 32 is attached to the orbiting plate 17, and the annular body 33 is attached to the orbiting scroll 31. The outer peripheral surface of the annular body 32 and the inner peripheral surface of the annular body 33 are movably and airtightly in contact with each other, and a pressure chamber 34 is formed by the orbiting plate 17, the annular bodies 32 and 33, and the orbiting scroll 31. Yes. A passage 35 is provided in the orbiting scroll 31, and the passage 35 communicates a compression chamber (not shown) formed between the fixed scroll of the scroll fluid machine main body and the orbiting scroll 31 and the pressure chamber 34. .

このようなスクロール流体機械においては、始動開始から時間が経過するにつれて中間部の圧縮室内の圧力すなわち中間圧が上昇するが、圧縮室と圧力室３４とが通路３５により連通されているから、圧力室３４内の圧力も始動開始から時間が経過するにつれて上昇するので、中間圧の上昇に伴って徐々に強い力で旋回スクロール３１が旋回軸１１、ケーシング１に対して固定スクロール側に押される。このため、被圧縮ガスを有効に圧縮することができる。また、旋回軸１１、旋回板１７に対して旋回スクロール３１は回転しないから、圧力室３４のシールを容易に行なうことができるので、圧力室３４、圧縮室の圧力が低下することがないため、被圧縮ガスを有効に圧縮することができる。   In such a scroll fluid machine, the pressure in the intermediate compression chamber, that is, the intermediate pressure rises as time elapses from the start of starting, but the compression chamber and the pressure chamber 34 communicate with each other through the passage 35. Since the pressure in the chamber 34 also rises as time elapses from the start of the start, the orbiting scroll 31 is pushed toward the fixed scroll side with respect to the orbiting shaft 11 and the casing 1 with a gradually strong force as the intermediate pressure increases. For this reason, the gas to be compressed can be effectively compressed. Further, since the orbiting scroll 31 does not rotate with respect to the orbiting shaft 11 and the orbiting plate 17, the pressure chamber 34 can be easily sealed, so the pressure in the pressure chamber 34 and the compression chamber does not decrease. The compressed gas can be effectively compressed.

なお、図１〜図３に示した実施の形態、図４〜図６に示した実施の形態においては、２枚の支持板１２、２１を設けたが、１枚の支持板を設けてもよい。また、上述実施の形態においては、旋回軸１１がケーシング１から突出する方向側に自転防止装置を設けたが、旋回軸１１がケーシング１から突出する方向とは反対側に自転防止装置を設けてもよい。また、図７に示した実施の形態においては、旋回板１７と旋回スクロール３１との間に圧力室３４を形成したが、旋回板１７と旋回スクロール３１との間にバネ等の弾性体を設け、または旋回板１７と旋回スクロール３１との間に圧力室３４を形成するとともに、旋回板１７と旋回スクロール３１との間にバネ等の弾性体を設けてもよく、これらの場合にも旋回スクロール３１を旋回軸１１、ケーシング１に対して固定スクロール側に押すことができるから、被圧縮ガスを有効に圧縮することができる。   In the embodiment shown in FIGS. 1 to 3 and the embodiment shown in FIGS. 4 to 6, the two support plates 12 and 21 are provided, but one support plate may be provided. Good. Further, in the above-described embodiment, the rotation prevention device is provided on the side in which the turning shaft 11 protrudes from the casing 1, but the rotation prevention device is provided on the opposite side to the direction in which the turning shaft 11 protrudes from the casing 1. Also good. In the embodiment shown in FIG. 7, the pressure chamber 34 is formed between the orbiting plate 17 and the orbiting scroll 31, but an elastic body such as a spring is provided between the orbiting plate 17 and the orbiting scroll 31. Alternatively, the pressure chamber 34 may be formed between the orbiting plate 17 and the orbiting scroll 31, and an elastic body such as a spring may be provided between the orbiting plate 17 and the orbiting scroll 31, and also in these cases Since 31 can be pushed to the fixed scroll side with respect to the turning shaft 11 and the casing 1, the gas to be compressed can be effectively compressed.
