「実施例」
第１図および第２図は、本発明に係わる回転伝達装置の
第１実施例を示す正面図および平面図である。Embodiment FIGS. 1 and 2 are a front view and a plan view showing a first embodiment of a rotation transmission device according to the present invention.
図中符号１０は入力側の回転軸、１１は回転軸ＩＯに同
軸に固定された円板状の支持部、１２は支持部１．１の
外周に一定厚さに形成された着磁部であり、支持部１１
と着磁部１２とが回転体１３を構成している。In the figure, reference numeral 10 denotes the rotation axis on the input side, 11 denotes a disk-shaped support part coaxially fixed to the rotation axis IO, and 12 denotes a magnetized part formed with a constant thickness on the outer periphery of the support part 1.1. Yes, support part 11
and the magnetized portion 12 constitute a rotating body 13.
一方、符号１４は回転軸ＩＯと平行に配置された出力側

同径の円板状の支持部１５が固定されるとともに、その
外周には着磁部１６が形成され、これら支持部１５と着
磁部１６が回転体１７を構成している。そして各回転体
１３．１７ は、間隙が空くように外周面を対向させ
て配置されている。On the other hand, reference numeral 14 is an output-side rotation shaft arranged parallel to the rotation axis IO, and this rotation axis I4 has the support portion I! A disk-shaped support section 15 having the same diameter as the rotor is fixed, and a magnetized section 16 is formed on its outer periphery, and the support section 15 and the magnetized section 16 constitute a rotating body 17 . The rotating bodies 13, 17 are arranged with their outer peripheral surfaces facing each other with a gap between them.
着磁部１２，１６ は強磁性体で一体形成されたもの
で、その外周面が周方向交互にＳ極またはＮ極になるよ
うに、半径方向に着磁されている。The magnetized parts 12 and 16 are integrally formed of ferromagnetic material, and are magnetized in the radial direction so that the outer circumferential surface thereof becomes an S pole or a N pole alternately in the circumferential direction.
着磁部１２，１６ の材質としては着磁および一体成
形のしやすさの点から樹脂磁性体が好ましいが、フェラ
イトまたは金属等に着磁したものでも使用可能であるし
、着磁部１２．１６ をそれぞれ一体成形する代わり
に、小さな磁石片を支持部１１．１５ の外周に多数並
べて固定した構成も可能である。The material for the magnetized parts 12, 16 is preferably a resin magnetic material in terms of ease of magnetization and integral molding, but magnetized materials such as ferrite or metal can also be used. Instead of integrally molding each of the magnets 11.16, it is also possible to arrange a large number of small magnet pieces and fix them around the outer periphery of the support portion 11.15.
入力側の回転体！３の各磁極の周方向の長さは全て等し
く、各磁極の周方向両端と回転中心とがなす中心角はθ
Ａとなっている。Rotating body on the input side! The circumferential length of each magnetic pole in No. 3 is the same, and the central angle between the circumferential ends of each magnetic pole and the center of rotation is θ.
It is A.
一方、出力側の回転体１７では、隣接する各磁極の両端
と回転中心とがなす中心角が、図示の０°位置から１８
０°位置にかけてθｌ→θ５へと段階的に増大し、次い
で１８０°位置から３６０°（０°）位置にかけてθ５
−θｌへと段階的に減少するように設定されている。On the other hand, in the rotating body 17 on the output side, the central angle between both ends of each adjacent magnetic pole and the center of rotation is 18 degrees from the 0° position shown in the figure.
It gradually increases from θl to θ5 toward the 0° position, and then θ5 increases from the 180° position to the 360° (0°) position.
-θl is set to decrease stepwise.
例えば、第１１ｉＵの例では各中心角が以下のように設
定されている。For example, in the example of the 11th iU, each central angle is set as follows.
θＡ＝３０° θ１＝３０° θ２＝３３゜θ３＝
３６’ θ４＝３９° θ５＝４２゜勿論、この数
値は一例に過ぎず、磁極数や各中心角は適宜変更してよ
い。ただし、入力側の中心角θＡと、θ！〜５の各中心
角の比は１／２〜２倍の範囲でなければならない。２倍
以上またはｌ／２未満になると、対向する磁極間の磁気
結合力が著しく減少し、回転伝達が困難になる。θA=30° θ1=30° θ2=33° θ3=
36' θ4 = 39° θ5 = 42° Of course, these values are just an example, and the number of magnetic poles and each central angle may be changed as appropriate. However, the central angle θA on the input side and θ! The ratio of each central angle of ~5 must be in the range of 1/2 to 2 times. When it is more than twice or less than 1/2, the magnetic coupling force between opposing magnetic poles is significantly reduced, making rotation transmission difficult.
このように構成された回転伝達装置においては、入力側
の回転軸ＩＯを回転すると、回転体１３の磁極の回転に
つれて、回転体１７の対向する磁極がそれぞれ引かれ、
回転体１７が回転体１３と同じ磁極数だけ回転する。In the rotation transmission device configured in this way, when the input-side rotating shaft IO is rotated, as the magnetic poles of the rotating body 13 rotate, the opposing magnetic poles of the rotating body 17 are pulled, respectively.
The rotating body 17 rotates by the same number of magnetic poles as the rotating body 13.
よって、第３図のグラフに示すように、出力側回転体１
７の０°位置が入力側回転体１３と対向している状態で

図示の例ではｌ）になり、Ｉ８０°８０°対向した状態
ではθ５／θＡ（同１゜４）となる。すなわち、１８０
°毎に回転速度比が漸次増減する。Therefore, as shown in the graph of FIG.
When the 0° position of 7 faces the input rotating body 13, the rotational speed ratio of the output side to the input side is θ1/θA(
In the illustrated example, the angle is 1), and when the angles are opposed to each other at I80° and 80°, the angle becomes θ5/θA (1°4). That is, 180
The rotational speed ratio gradually increases or decreases every degree.
また、出力側の回転トルクは、対向する各磁極の中心角
が等しいほど大きいため、この例では０°位置が対向し
た状態で最大、１８０°位置が対向した状態で最小とな
る。Furthermore, since the rotational torque on the output side is greater as the central angles of the opposing magnetic poles are equal, in this example, it is maximum when the magnetic poles are opposed at the 0° position, and is minimum when the magnetic poles are opposed at the 180° position.
この装置によれば、各回転体１２．１６ の磁極の着

Even in liquids, there is little change in performance over a long period of time, so there is a high degree of freedom in use and excellent versatility.
さらに、各回転体１３．１７ は互いに非接触でよい
ため、ギアのような騒音が生じず、振動や熱を伝達する
こともなく、入力側と出力側とを完全に分離することが
できる。Further, since the rotating bodies 13, 17 do not need to be in contact with each other, the input side and the output side can be completely separated without generating noise like gears, without transmitting vibration or heat.
なお、上記第１実施例では、個々の磁極が半径方向に着
磁されていたが、その代わりに着磁部１２．１６ の厚
さ方向に着磁してもよいし、あるいは周方向に交互に着
磁してもよい。In the first embodiment, the individual magnetic poles are magnetized in the radial direction, but instead, they may be magnetized in the thickness direction of the magnetized portion 12.16, or alternately in the circumferential direction. It may also be magnetized.

By changing , the distribution of rotational torque can be changed. For example, FIG. 4 is a graph showing the rotational speed ratio and rotational torque when the central angle θA is changed to 45°.
図示のように、回転速度比の変化率は第３図と変わらな
いが、回転トルクは第３図とは逆に０°位置で最小、１
８０゜位置で最大となる。As shown in the figure, the rate of change in the rotational speed ratio is the same as in Figure 3, but the rotational torque is at its minimum at the 0° position and at 1
Maximum at 80° position.
また、上記実施例では回転軸１４を出力側、回転軸ｌＯ
を入力側としていたが、これらを逆にしてもよい。Further, in the above embodiment, the rotating shaft 14 is on the output side, and the rotating shaft lO
is used as the input side, but these may be reversed.
次に、第５図は本発明の第２実施例を示し、この例では
