本考案は、障害物があり、中心点を設は難い構造のもの
に適用して大きな効果を発揮する回転伝達装置に関する
ものである。[Detailed Description of the Invention] The present invention relates to a rotation transmission device that is highly effective when applied to structures where there are obstacles and it is difficult to establish a center point.
従来、構造物を回転させる場合、殆んどが回転中心に軸
を固定し、これを中心として回転させる構成が用いられ
ている。Conventionally, when rotating a structure, most of the structures have a structure in which a shaft is fixed at the center of rotation and the structure is rotated around this shaft.
また、中心点が設は難いものは、第１図に示す如く、回
転構造物１′に円弧状の長穴２′を設け、この長穴内に
位置するよう一対のピン３′を固定し、ピン３′を中心
に回転構造物１′を回動させる構成が用いられている。In addition, if it is difficult to set the center point, as shown in FIG. 1, an arc-shaped long hole 2' is provided in the rotating structure 1', and a pair of pins 3' are fixed so as to be located in this long hole. A configuration is used in which the rotating structure 1' is rotated around a pin 3'.
しかしながら、この構成においては、回転半径が極端に
小さくなると、円滑な回動が望めず、また回転構造物１
′を動かすためζこｉよ外部に動力装置を設ける必要が
あり、構成が複雑で大形化する欠点があった。However, in this configuration, if the rotation radius becomes extremely small, smooth rotation cannot be expected, and the rotating structure 1
In order to move the motor, it is necessary to install a power device external to the motor, which has the disadvantage of making the structure complicated and large.
本考案は上記従来の欠点に鑑みてなされたもので、以下
本考案の一実施例を第２図を参照し、て説明する。The present invention has been devised in view of the above-mentioned drawbacks of the conventional art, and one embodiment of the present invention will be described below with reference to FIG. 2.
図において、１は回転購造：ｐ’ｔフで、仮想中心Ｐが
同一で半径を異にする外歯２と内歯３を対向して設けて
いる。In the figure, reference numeral 1 indicates a rotating gear: p't, in which external teeth 2 and internal teeth 3 having the same virtual center P and different radii are provided facing each other.
４，５は外歯２と内歯３との間に形成される空間６内に
位置し、外歯２と内歯３の仮想中心Ｐを通るＡ−Ａ線上
に位置させた回転軸で、回転軸４は駆動源（図示せず）
に連結している。4 and 5 are rotational shafts located in the space 6 formed between the external teeth 2 and internal teeth 3, and located on the line A-A passing through the virtual center P of the external teeth 2 and internal teeth 3; The rotating shaft 4 is a driving source (not shown)
is connected to.
７は外歯２と噛合う歯車で、回転軸４に固定されている
。A gear 7 meshes with the external teeth 2 and is fixed to the rotating shaft 4.
８は内歯３と噛合う歯車で、歯車７と噛合う中間歯車９
とともに回転軸５に固定している。8 is a gear that meshes with the internal gear 3, and an intermediate gear 9 that meshes with the gear 7.
It is also fixed to the rotating shaft 5.
以上の構成において、芯なし回転が円滑にできるように
するには、仮想中心Ｐを中心とした外歯２までの距離ｒ
と内歯３までの距離Ｈの比が、歯車Ｔと歯車８の回転比
率と等しくなればよい。In the above configuration, in order to perform centerless rotation smoothly, the distance r from the virtual center P to the external tooth 2 must be
It is only necessary that the ratio of the distance H to the internal tooth 3 be equal to the rotation ratio of the gear T and the gear 8.
すなわち、Ｒ：ｒ−歯車８：歯車７の条件を満足させる
ことにより、回転構造物１を円滑に回動させることがで
きる。That is, by satisfying the condition R:r-gear 8:gear 7, the rotating structure 1 can be rotated smoothly.
なお、上記実施例においては、回転軸４を駆動源に連結
して歯車７を駆動歯車としているが、回転軸５を駆動源
に連結して歯車８を駆動歯車としてもよいものである。In the above embodiment, the rotating shaft 4 is connected to a drive source and the gear 7 is used as a driving gear, but the rotating shaft 5 may be connected to a driving source and the gear 8 is used as a driving gear.
また、歯車１に中間歯車を設け、この中間歯車を歯車８
に噛合うように構成してよく、さらに両歯車７，８にそ
れぞれ中間歯車を設け、雨中間歯車を噛合すように構成
してもよいものである。Further, an intermediate gear is provided in the gear 1, and this intermediate gear is connected to the gear 8.
Further, both gears 7 and 8 may be provided with intermediate gears, respectively, and the intermediate gears may be configured to mesh with each other.
以上の説明から明らかなように本考案によれば、回転構
造物内に位置させる歯車を動力として回転構造を回動さ
せることが可能であり、また、歯車により回転構造物を
動かすため、従来のピン支持方式に比して極めて小さい
回転半径でも円滑に動かすことができ、中心付近に障害
物があり、中心点を設は難い構造に適用して大きな効果
を発揮するものである。As is clear from the above description, according to the present invention, it is possible to rotate the rotating structure by using the gears located within the rotating structure as power, and since the rotating structure is moved by the gears, it is possible to rotate the rotating structure using the gears located inside the rotating structure. It can be moved smoothly even with an extremely small rotation radius compared to the pin support method, and is highly effective when applied to structures where there are obstacles near the center and it is difficult to set the center point.
