Abstract

Lever action is used for amplifying power when obtaining power from devices that acquire a driving force from human strength or from devices with weak driving forces. When doing so, power transmission mechanisms using only mating gears are not ideal for transportation-related or power generator drive devices because the stroke of the oscillation movement is short, and because increasing the number of revolutions significantly reduces torque and is impractical, a mechanism that does not significantly reduce torque and is capable of multiple revolutions with a single oscillation is desired. Using a set of bevel gears, extending two arms so that one bevel gear can swing on the other fixed bevel gear, machining a spiral groove in the swinging bevel gear so that the swinging bevel gear can be used as a ball screw nut, mounting a rolling bearing on the boss and connecting the rolling bearing to the swing arms with members associated therewith makes it possible for the ball screw bevel gear nut to roll on the tooth surface of the partner bevel gear. Configuring so that the ball screw bolt tilts parallel to the lever at the point of action thereof and inserting the ball screw bolt in the bevel gear nut allows a configuration in which multiple revolutions are possible with a single oscillation.

Description

[規則91に基づく訂正 03.10.2013]　テコの揺動により固定された傘歯車軸との間に発生する軸間距離変動を機械的に自動調整する機構[Correction based on Rule 91 03.10.2013] A mechanism that automatically adjusts the inter-shaft distance fluctuation that occurs with the bevel gear shaft fixed by lever swing.
　本発明はテコによる揺動運動を傘歯車とボールねじを用い逆作動させることで回転運動に変えるものであるが、そのさいテコは円弧を描いて揺動し、固定された傘歯車軸との間に軸間距離変動が発生するため、それを機械的に自動調整する機構に関する。 In the present invention, the swinging motion by the lever is changed to the rotational motion by reversely operating it using a bevel gear and a ball screw. However, the lever swings in a circular arc and is fixed to the fixed bevel gear shaft. The present invention relates to a mechanism for mechanically automatically adjusting an inter-axis distance variation between them.
　人力や微風力発電による駆動力を伝達する部材や機構は主に噛み合い型歯車のみを用いたりチェーンを用いたものが主流である。 Most of the members and mechanisms that transmit the driving force generated by human power or light wind power generation mainly use meshing gears or chains.
特表平２－５０４５４５号公報Japanese Patent Publication No. 2-504545
　テコの揺動運動から駆動力を得ている駆動装置においては、揺動運動ストロークが短いため噛み合い型歯車のみを用いている機構では、トルクを大きく減じさせずに１揺動あたりの回転数を上げることが困難である。 In a drive device that obtains driving force from the lever swinging motion, the swinging motion stroke is short, so in a mechanism using only meshing gears, the number of revolutions per swinging can be reduced without greatly reducing the torque. It is difficult to raise.
　そのため速度を必要とする運輸関係や回転数を必要とする発電機の駆動装置また人力駆動や弱い駆動力機関に噛み合い型歯車のみを用いて駆動力を伝達する機構は理想的ではないため、揺動運動ストロークが短くても１揺動多数回転させられる機構が望まれる。 For this reason, a mechanism for transmitting the driving force using only meshing gears to a driving mechanism of a generator that requires speed, a generator that requires a rotational speed, or a manual driving or a weak driving force engine is not ideal. A mechanism capable of rotating one swing many times even if the dynamic motion stroke is short is desired.
　本発明は上記目的を達成させるため、一言でいうと次のような構成とした。それはテコの動きをボールねじで逆作動させると小さい揺動でも回転を稼ぐこととができ、ナット側の傘歯車がテコの揺動により角度や向き、また歯車の軸間距離が変動してもスムーズに回転できる構造である。 In order to achieve the above object, the present invention has the following configuration in a word. If the lever movement is reversed with a ball screw, rotation can be achieved even with a small swing. Even if the bevel gear on the nut side changes the angle and direction due to the swing of the lever and the distance between the shafts of the gear varies. It can be rotated smoothly.
　まず揺動するテコの先端であり作用点でもある部位にボールねじボルトをテコと平行に倒れることができるように設ける。ボルトの長さはテコの揺動範囲の長さとしテコ側のみの片支持である。 First of all, a ball screw bolt is provided at the tip of the swinging lever and the point of action so that it can fall in parallel with the lever. The length of the bolt is the length of the swinging range of the lever, and it is a single support on the lever side only.
　このボールねじボルトにナットとしての加工を施した傘歯車をナットとして組み合わせる。 ∙ Combine this ball screw bolt with a bevel gear that has been processed as a nut as a nut.
　このボールねじ傘歯車ナットがかみ合う相手も傘歯車７であり、向きは次の方向に限定される。ボールねじが設けられているテコの揺動する軌跡を面として見た時、この面に傘歯車７の小端面が接するように垂直に向き、傘歯車ナットと互いに中心線が垂直に交差する位置とする。 The opponent with which the ball screw bevel gear nut is engaged is also the bevel gear 7, and the direction is limited to the following direction. When the swinging locus of the lever provided with the ball screw is viewed as a surface, the surface is oriented vertically so that the small end surface of the bevel gear 7 is in contact with this surface, and the center line of the bevel gear nut and the center line intersect each other vertically. And
　ボールねじ傘歯車ナットは、テコの作用点でもある先端にテコと平行に倒れることができるようにピンで止められているボールねじボルトに組み込まれているだけなので、このままではテコが揺動すれば相方である傘歯車７からかみ合いがズレてしまい機能しなくなる。そこで本発明のポイントになる部材を次のように設ける。 The ball screw bevel gear nut is only incorporated in a ball screw bolt that is fixed with a pin so that it can fall in parallel with the lever at the tip, which is the point of action of the lever, so if the lever swings as it is The meshing is shifted from the opposite bevel gear 7 and it does not function. Therefore, the members which are the points of the present invention are provided as follows.
　傘歯車７を支える中心軸からボールねじ傘歯車ナットがブランコできるように２本のアームを出す。ひとつは傘歯車７を片支持している大端面側からのアームと、もうひとつは小端先面側にあるボールねじ傘歯車ナットを挟んだ向い側の軸からアームを出して、ボールねじ傘歯車ナットが傘歯車７の歯面をブランコするような転がり移動ができるようにする。 ２Take out two arms so that the ball screw bevel gear nut can swing from the central axis that supports the bevel gear 7. One is an arm from the large end surface side that supports the bevel gear 7 in one piece, and the other is an arm from the opposite side of the ball screw bevel gear nut on the small end tip surface side, and the ball screw umbrella The rolling movement is performed such that the gear nut swings the tooth surface of the bevel gear 7.
　傘歯車７の中心軸が片支持となっている理由は、傘歯車７の小端先にはボールねじボルトが傘歯車７の中心軸線を垂直に横切る運動をするため、１本の通し軸にすることができないため片支持となっている。 The reason why the central shaft of the bevel gear 7 is unilaterally supported is that the ball screw bolt moves at the small end of the bevel gear 7 perpendicularly across the central axis of the bevel gear 7, so that one through shaft is provided. Since it cannot be done, it is a single support.
　では次にこれらの動きや作用を説明すると次のようになる。テコが揺動すると、添付図面の場合作用点でもあるテコの先端に設けたボールねじが傘歯車ナットを押し上げるが、傘歯車７にはばまれてボルトとは一緒に移動できない。ボルトにはボールねじの特徴である螺旋溝が設けてあるため、傘歯車ナットはその溝に添ってその場で回転することで力を逃がし現状の位置を保ち続けようとして元の位置を目指して回転するいわゆる逆作動をする。 Next, these movements and actions will be explained as follows. When the lever swings, a ball screw provided at the tip of the lever, which is also an action point in the case of the attached drawing, pushes up the bevel gear nut, but is caught by the bevel gear 7 and cannot move together with the bolt. Since the bolt has a spiral groove that is characteristic of a ball screw, the bevel gear nut rotates on the spot along the groove to release the force and keep the current position aiming for the original position The so-called reverse operation that rotates.
　ところがテコの先端は円弧を描いて揺動し傘歯車７から遠ざかるため、ボールねじボルトは変動する距離を埋めるため、テコと止められているピンのところから倒れ込みおじぎをする格好で距離を埋める。 However, since the tip of the lever swings in an arc and moves away from the bevel gear 7, the ball screw bolt fills in the fluctuating distance, so that the distance from the pin pinned to the lever falls down and bows.
　更にボールねじ傘歯車ナット５は傘歯車７の中心軸線ＢＢを中心に適正ピッチを保ちブランコできるようになっており、テコ１の揺動でボールねじボルト６をピン１３で止めている作用点が持ち上がり、ボールねじ傘歯車ナット５がおじぎするように倒れ込むと同時に、ボールねじ傘歯車ナット５は傘歯車７の歯面を転がり移動してブランコアーム４をテコ側に引き寄せ、テコの揺動で傘歯車７との軸間距離が変化した分だけ軸間距離を機械的に自動調整する。 Further, the ball screw bevel gear nut 5 can swing while maintaining an appropriate pitch around the central axis BB of the bevel gear 7, and the action point of the ball screw bolt 6 being stopped by the pin 13 by the swing of the lever 1 is as follows. As the ball screw bevel gear nut 5 is lifted and falls down, the ball screw bevel gear nut 5 rolls and moves on the tooth surface of the bevel gear 7 and pulls the swing arm 4 to the lever side. The distance between the shafts is mechanically automatically adjusted by the amount that the distance between the shafts with the gear 7 is changed.
　テコの揺動運動から駆動力を得ている駆動装置において、エネルギー変換効率のよいボールねじを逆作動させることで、ストロークの短いテコの揺動運動でも、トルクを大きく減じさせることなく、１揺動多数回転を得ることが可能となる。 In a driving device that obtains a driving force from the lever swinging motion, the ball screw with high energy conversion efficiency is reversely operated, so that even a lever swinging motion with a short stroke does not significantly reduce the torque, It becomes possible to obtain a large number of dynamic rotations.
　速度を必要とする運輸関係や、回転数を必要とする発電機の駆動装置に利用可能となる。 It can be used for transportation related to speed and generator drive devices that require rotation speed.
　この機構は人力や弱い駆動力をテコで増幅した後、回転運動として取り出す機構に利用可能である。 This mechanism can be used for a mechanism that amplifies human power or weak driving force with a lever and then extracts it as a rotational motion.
本発明の構造を示す見取図A sketch showing the structure of the present invention
　揺動するテコ１の先端部であり作用点でもある部位にボールねじボルト６をテコ１と平行に倒れることができるようにピン１３で片支持止めにする。 The ball screw bolt 6 is fixed to one end with a pin 13 so that the ball screw bolt 6 can be tilted in parallel with the lever 1 at a portion which is a tip portion of the swinging lever 1 and is also an action point.
　ボールねじボルト６にボールねじナットとしての加工を施した傘歯車を、ボールねじ傘歯車ナット５として組み合わせる。 傘 Combine bevel gear nuts 5 are combined with ball screw bolts 6 that have been processed as ball screw nuts.
　このボールねじ傘歯車ナット５がかみ合う相手も傘歯車であり、組合わせと向きは次の方向に限定される。ボールねじが設けられているテコ１の揺動する軌跡を面として見た時、この面に傘歯車７の小端面が接するように垂直に向き、ボールねじ傘歯車ナット５と互いに中心線が垂直に交差する位置とする。 The other party with which the ball screw bevel gear nut 5 meshes is also a bevel gear, and the combination and direction are limited to the following directions. When the swinging trajectory of the lever 1 provided with the ball screw is viewed as a plane, it is oriented vertically so that the small end surface of the bevel gear 7 is in contact with this plane, and the center line of the ball screw bevel gear nut 5 is perpendicular to each other. The position that intersects with.
　傘歯車７を支える中心軸１０から、ボールねじ傘歯車ナット５がブランコできるように、２本のブランコアーム４を出す。１本は傘歯車７の大端面側から出るブランコアーム４と、もう１本は小端先面側にあるボールねじ傘歯車ナット５を挟んだ向い側の軸からブランコアーム４を出す。 The two swing arms 4 are extended from the central shaft 10 supporting the bevel gear 7 so that the ball screw bevel gear nut 5 can swing. One swings out the swing arm 4 from the large end face side of the bevel gear 7 and the other swings out the swing arm 4 from the opposite shaft sandwiching the ball screw bevel gear nut 5 on the small end front face side.
　ボールねじ傘歯車ナット５をスムーズに回転させるための転がり軸受け２がボールねじ傘歯車ナット５のボスに取り付けられていて、２本のブランコアーム４は転がり軸受け２をボールねじ傘歯車ナット保持部材３で掴み、ブランコアーム４と連結させる。 A rolling bearing 2 for smoothly rotating the ball screw bevel gear nut 5 is attached to a boss of the ball screw bevel gear nut 5. And is connected to the swing arm 4.
傘歯車７の小端先にはボールねじボルトの揺動方向ＡＡと傘歯車７の中心軸線ＢＢとが垂直に交わる運動をするため、傘歯車７の軸は１本の通し軸にすることができないため片支持となっている。 Since the swinging direction AA of the ball screw bolt and the central axis BB of the bevel gear 7 intersect perpendicularly at the small end of the bevel gear 7, the axis of the bevel gear 7 may be a single through shaft. Because it is not possible, it is a single support.
