しかし、このような偏心旋回駆動装置を有する装置においては、旋回軸の振動を抑制することができないから、被駆動部材の振動を抑制することができない。   However, in an apparatus having such an eccentric turning drive device, vibration of the turning shaft cannot be suppressed, and therefore vibration of the driven member cannot be suppressed.

本発明は上述の課題を解決するためになされたもので、被駆動部材の振動を抑制することができる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 thereof is to provide an eccentric turning drive device that can suppress vibration of a driven member.

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、上記旋回軸の偏心旋回を許容しかつ上記旋回軸の自転を防止する自転防止手段と、上記旋回軸に回転可能に支持されかつ上記回転軸と連結された錘板体とを設ける。   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 rotating shaft that is supported eccentrically and rotatably, an anti-rotation means that allows the rotating shaft to rotate eccentrically and prevents the rotating shaft from rotating, and a rotating shaft that is rotatably supported by the rotating shaft and connected to the rotating shaft. The weight plate body is provided.

この場合、上記自転防止手段に旋回板を設け、上記錘板体の回転軸に直角なモーメントベクトル、被駆動部材の回転軸に直角なモーメントベクトルおよび上記旋回板の回転軸に直角なモーメントベクトルの和を零ベクトルとする。   In this case, the rotation preventing means is provided with a swivel plate, and a moment vector perpendicular to the rotation axis of the weight plate body, a moment vector perpendicular to the rotation axis of the driven member, and a moment vector perpendicular to the rotation axis of the swivel plate are provided. Let the sum be the zero vector.

これらの場合、上記自転防止手段をしてピンクランクを有するものを用いてもよい。   In these cases, the rotation preventing means may be used having a pin crank.

本発明に係る偏心旋回駆動装置においては、旋回軸の振動を抑制することができるから、被駆動部材の振動を抑制することができる。   In the eccentric turning drive device according to the present invention, the vibration of the turning shaft can be suppressed, and therefore the vibration of the driven member can be suppressed.

また、自転防止手段に旋回板を設け、錘板体の回転軸に直角なモーメントベクトル、被駆動部材の回転軸に直角なモーメントベクトルおよび旋回板の回転軸に直角なモーメントベクトルの和を零としたときには、旋回軸の振動を確実に抑制することができるから、被駆動部材の振動を確実に抑制することができる。   Also, a rotation plate is provided in the rotation prevention means, and the sum of the moment vector perpendicular to the rotation axis of the weight plate body, the moment vector perpendicular to the rotation axis of the driven member and the moment vector perpendicular to the rotation axis of the rotation plate is zero. When this is done, the vibration of the turning shaft can be reliably suppressed, so that the vibration of the driven member can be reliably suppressed.

また、錘板体として、錘板と、錘板に取り付けられた錘とを有するものを用いたときには、錘板の加工が容易となるから、製造コストが安価になる。   Further, when a weight plate body having a weight plate and a weight attached to the weight plate is used, the weight plate can be easily processed, so that the manufacturing cost is reduced.

また、自転防止手段をしてピンクランクを有するものを用いたときには、旋回軸の振動を小さくすることができるから、被駆動部材の振動を小さくすることができる。   Further, when the rotation prevention means having a pin crank is used, the vibration of the turning shaft can be reduced, and therefore the vibration of the driven member can be reduced.

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、ピンクランク１４等からなる自転防止手段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。また、図４(ａ)に示す状態（図１〜図３に示す状態）では、旋回軸１１の中心線は回転軸７の中心線よりも図４紙面右方に位置しているのに対して、錘板体２４の重心は回転軸７の中心線よりも図４紙面左方に位置しており、旋回軸１１の中心線と錘板体２４の重心とは回転軸７の中心線の両側に位置している。また、図４(ｂ)に示すように、図４(ａ)に示す状態から回転軸７が９０度回転した状態では、旋回軸１１の中心線は回転軸７の中心線よりも図４紙面下方に位置しているのに対して、錘板体２４の重心は回転軸７の中心線よりも図４紙面上方に位置しており、旋回軸１１の中心線と錘板体２４の重心とは回転軸７の中心線の両側に位置している。また、図４(ｃ)に示すように、図４(ｂ)に示す状態から回転軸７が９０度回転した状態では、旋回軸１１の中心線は回転軸７の中心線よりも図４紙面左方に位置しているのに対して、錘板体２４の重心は回転軸７の中心線よりも図４紙面右方に位置しており、旋回軸１１の中心線と錘板体２４の重心とは回転軸７の中心線の両側に位置している。また、図４(ｄ)に示すように、図４(ｃ)に示す状態から回転軸７が９０度回転した状態では、旋回軸１１の中心線は回転軸７の中心線よりも図４紙面上方に位置しているのに対して、錘板体２４の重心は回転軸７の中心線よりも図４紙面下方に位置しており、旋回軸１１の中心線と錘板体２４の重心とは回転軸７の中心線の両側に位置している。そして、図４(ｄ)に示す状態から回転軸７が９０度回転すると、図４(ａ)に示す状態になる。すなわち、回転軸７の回転角度にかかわらず、旋回軸１１の中心線と錘板体２４の重心とは回転軸７の中心線の両側に位置する。   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 means including the pin crank 14 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. Further, in the state shown in FIG. 4A (the state shown in FIGS. 1 to 3), the center line of the turning shaft 11 is located on the right side of FIG. Thus, the center of gravity of the weight plate 24 is located on the left side of FIG. 4 with respect to the center line of the rotary shaft 7, and the center line of the turning shaft 11 and the center of gravity of the weight plate 24 are the center line of the rotary shaft 7. Located on both sides. Further, as shown in FIG. 4B, when the rotary shaft 7 is rotated 90 degrees from the state shown in FIG. 4A, the center line of the turning shaft 11 is more than the center line of the rotary shaft 7 in FIG. In contrast, the center of gravity of the weight plate body 24 is located above the center line of the rotary shaft 7 in FIG. 4, and the center line of the pivot shaft 11 and the center of gravity of the weight plate body 24 Are located on both sides of the center line of the rotating shaft 7. Also, as shown in FIG. 4C, when the rotary shaft 7 is rotated 90 degrees from the state shown in FIG. 4B, the center line of the turning shaft 11 is more than the center line of the rotary shaft 7 in FIG. Whereas the center of gravity of the weight plate body 24 is located to the right of the center of the rotary shaft 7 in FIG. The center of gravity is located on both sides of the center line of the rotating shaft 7. Further, as shown in FIG. 4D, when the rotary shaft 7 is rotated 90 degrees from the state shown in FIG. 4C, the center line of the turning shaft 11 is more than the center line of the rotary shaft 7 in FIG. The center of gravity of the weight plate body 24 is located below the center line of the rotating shaft 7 in FIG. 4 with respect to the center line of the pivot shaft 11 and the center of gravity of the weight plate body 24. Are located on both sides of the center line of the rotating shaft 7. Then, when the rotary shaft 7 rotates 90 degrees from the state shown in FIG. 4D, the state shown in FIG. That is, regardless of the rotation angle of the rotating shaft 7, the center line of the turning shaft 11 and the center of gravity of the weight plate body 24 are located on both sides of the center line of the rotating shaft 7.

このような偏心旋回駆動装置においては、旋回軸１１の中心線と錘板体２４の重心とは回転軸７の中心線の両側に位置するから、バランスをとることができるので、旋回軸１１、被駆動部材の振動を抑制することができる。このため、回転軸７の回転数を大きくすることができるから、被駆動部材を高速で駆動することができる。また、錘板体２４の回転軸に直角なモーメントベクトル、被駆動部材の回転軸に直角なモーメントベクトルおよび旋回板１２の回転軸に直角なモーメントベクトルの和を零としているから、すなわち被駆動部材の回転軸に直角なモーメントベクトルおよび旋回板１２の回転軸に直角なモーメントベクトルの和を和ベクトルとしたとき、錘板体２４の回転軸に直角なモーメントベクトルの大きさを和ベクトルの大きさと等しくしかつ錘板体２４の回転軸に直角なモーメントベクトルの方向を和ベクトルの方向と反対方向としているから、旋回軸１１の振動を確実に抑制することができるので、被駆動部材の振動を確実に抑制することができる。また、錘板１５に錘１９を取り付けているから、錘板１５の形状を円形状とすることができるので、錘板１５の加工が容易となるため、製造コストが安価になる。また、自転防止手段としてピンクランク１４を有するものを用いているから、旋回軸１１の振動を小さくすることができるので、被駆動部材の振動を小さくすることができる。   In such an eccentric turning drive device, since the center line of the turning shaft 11 and the center of gravity of the weight plate body 24 are located on both sides of the center line of the rotating shaft 7, a balance can be taken. The vibration of the driven member can be suppressed. For this reason, since the rotation speed of the rotating shaft 7 can be increased, the driven member can be driven at a high speed. Further, the sum of the moment vector perpendicular to the rotational axis of the weight plate 24, the moment vector perpendicular to the rotational axis of the driven member, and the moment vector perpendicular to the rotational axis of the swivel plate 12 is set to zero. The sum of the moment vector perpendicular to the rotation axis of the rotating plate 12 and the moment vector perpendicular to the rotation axis of the swivel plate 12 is the sum vector, and the magnitude of the moment vector perpendicular to the rotation axis of the weight plate body 24 is the magnitude of the sum vector. Since the direction of the moment vector that is equal and perpendicular to the rotation axis of the weight plate body 24 is the direction opposite to the direction of the sum vector, the vibration of the swivel shaft 11 can be reliably suppressed. It can be surely suppressed. In addition, since the weight 19 is attached to the weight plate 15, the weight plate 15 can be formed in a circular shape, so that the weight plate 15 can be easily processed, and the manufacturing cost is reduced. Moreover, since the thing which has the pin crank 14 is used as a rotation prevention means, since the vibration of the rotating shaft 11 can be made small, the vibration of a driven member can be made small.

図５は図１〜図３に示した偏心旋回駆動装置を擂り鉢の擂り粉木を駆動する装置に用いた状態を示す概略図である。図に示すように、収納部６１に擂り鉢６２が固定され、擂り鉢６２の上方に偏心旋回駆動装置６３が設けられ、偏心旋回駆動装置６３の旋回軸（出力軸）１１のケーシング１からの突出部に擂り粉木６４が固定されている。   FIG. 5 is a schematic view showing a state in which the eccentric swivel driving device shown in FIGS. As shown in the figure, a bowl 62 is fixed to the storage portion 61, an eccentric turning drive device 63 is provided above the bowl 62, and the turning shaft (output shaft) 11 of the eccentric turning drive device 63 from the casing 1 is provided. A ground powder wood 64 is fixed to the protruding portion.

そして、偏心旋回駆動装置６３を駆動するとともに、擂り鉢６２の上部からゴマ等を供給すると、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から、擂り鉢６２と擂り粉木６４とによりゴマ等を擂ることができ、ゴマ等を擂ったものは収納部６１内に収納される。   When the eccentric turning drive device 63 is driven and sesame or the like is supplied from the upper portion of the roasting bowl 62, the rotating shaft 11 rotates eccentrically without rotating with respect to the casing 1. The sesame and the like can be beaten by the above, and the sesame and the like are beaten in the storage portion 61.

図６は図１〜図３に示した偏心旋回駆動装置を石うすの駆動装置に用いた状態を示す概略図である。図に示すように、下石７２と上石７３とを有する石うす７１の上方に偏心旋回駆動装置６３が設けられ、偏心旋回駆動装置６３の旋回軸（出力軸）１１のケーシング１からの突出部に上石７３が固定されている。   FIG. 6 is a schematic view showing a state in which the eccentric turning drive device shown in FIGS. 1 to 3 is used in a stone drive device. As shown in the figure, an eccentric turning drive device 63 is provided above a stone wheel 71 having a lower stone 72 and an upper stone 73, and a protruding portion of the turning shaft (output shaft) 11 of the eccentric turning drive device 63 from the casing 1. The upper stone 73 is fixed to the top.

そして、偏心旋回駆動装置６３を駆動するとともに、上石７３の穴７４からそば等を投入すると、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から、上石７３が下石７２に対して回転せずに偏心旋回するので、石うす７１によりそば等を碾く（すり砕く）ことができる。また、そば等が上石７３と下石７２との間に確実に取り込まれ、そば等が上石７３と下石７２との間に一度入ったのちに上石７３と下石７２との間から再度出たりすることがないから、そば等を一様に碾くことができるので、粒径が均一な良質なそば粉等を得ることができる。   When the eccentric turning drive device 63 is driven and a buckwheat or the like is inserted from the hole 74 of the upper stone 73, the turning shaft 11 turns eccentrically without rotating with respect to the casing 1. Since it rotates eccentrically without rotating, the soba etc. can be crushed (ground) with stone stone 71. Also, the buckwheat and the like are surely taken in between the upper stone 73 and the lower stone 72, and once the buckwheat etc. is once inserted between the upper stone 73 and the lower stone 72, the space between the upper stone 73 and the lower stone 72 The soba and the like can be uniformly sown, so that a good quality buckwheat flour with a uniform particle size can be obtained.

なお、上述実施の形態においては、被駆動部材が擂り粉木６４、上石７３である場合について説明したが、被駆動部材が他の被駆動装置の被駆動部材である場合にも本発明の偏心旋回駆動装置を使用することができる。また、上述実施の形態においては、錘板１５に錘１９を取り付けたが、錘板の形状を錘板の重心位置が旋回軸の中心線と一致しない位置となるような形状にすれば、錘板に錘を取り付けなくてもよく、錘板のみで錘板体を構成することができる。また、上述実施の形態においては、回転軸７にピン１７を取り付け、錘板１５に係合材１８を取り付けたが、錘板にピンを取り付け、回転軸に係合材を取り付けてもよい。また、上述実施の形態においては、錘板１５に係合材１８を取り付けたが、回転軸に取り付けられたピンが係合すべき穴を錘板に設けてもよく、また錘板に取り付けられたピンが係合すべき穴を回転軸に設けてもよい。この場合、ピンと穴との間にわずかな隙間を設け、錘板を回転軸に対して回転軸の中心線と旋回軸の中心線とを結ぶ線の方向に移動可能にする。すなわち、連結手段は、錘板体の回転軸に対する回転軸の中心線と旋回軸の中心線とを結ぶ線の方向の移動を許容する。また、上述実施の形態においては、図３における回転軸７の中心線と旋回軸１１の中心線とを結ぶ線上にピン１７の中心線を位置させたが、ピンの位置はこの位置には限定されない。また、上述実施の形態においては、旋回板１２、ピンクランク１４等により構成された自転防止手段を用いたが、他の自転防止手段を用いてもよい。   In the above-described embodiment, the case where the driven member is the sawdust 64 and the upper stone 73 has been described. However, the present invention can be applied to the case where the driven member is a driven member of another driven device. An eccentric turning drive can be used. In the above embodiment, the weight 19 is attached to the weight plate 15.
