はこの要請に応えるものである。DETAILED DESCRIPTION OF THE INVENTION As a component of robots and other equipment, there is a need for a reduction gear device that is compact, has a large reduction ratio, and can mesh with internal gears without backlash. The present invention meets this need.

数は、ギア２より僅かに多くしである。The bellows tube 6 is a cylindrical bellows with rigid or flexible ring plates a and b fixed to both ends thereof. The bellows tube 6 is housed in the case 3, and the ring plate is attached to the collar 5 provided on the output shaft 5.
It is fixed to b. A face gear 1.2 (hereinafter abbreviated as "gear") is provided facing the inner surface of the lid A and the outer surface of the ring plate a, and is capable of engaging with the inner surface of the lid A. Gear 1 has slightly more teeth than gear 2.
ギア２は別に作ったものをリング板ａへ固着してもよい

動可能となっている。The gear 2 may be made separately and fixed to the ring plate a, or may be geared directly to the outer surface of the ring plate a. Inclined plate 7
is fixed to the input shaft at an angle inclined with respect to the input axis, and is slidable while pressing the inner surface of the ring plate a with the edge of the surface.

射状の軸７ａを突出させ、これにローラｌＯを被挿して
ローラによる転動接触としてもよい。A countersunk 8 is inserted between the inclined plate 7 and the end face of the output shaft 5, and a distance ring 9 is inserted between the collar 5b of the output shaft and the lid B. That is, the inclined plate always presses a part of the gear 2 against the gear 1 via the ring plate a. As the inclined plate rotates, it may press down the back surface of the ring plate a one after another, so it is not necessarily necessary to make it circular as shown in FIG. Although not shown, it may be shaped like a wedge, with the base of the handle fixed to the input shaft and pressed by the head. Also, the inclined plate should have a small diameter as shown in Figures 2 and 3.
A radial shaft 7a may be made to protrude, and a roller 10 may be inserted into the shaft 7a to provide rolling contact with the roller.
本発明は以上のように構成される。入力軸が回転すると

対しギア２は 回転する。従って例え
ｎｌ
ばｎｌ＝ １００ 、 ｎ２＝ ９９ とするとギア１
の１回転に対しギア２は１征回転することになる。The present invention is configured as described above. When the input shaft rotates, the inclined plate engages the gears 1.2 one after another, and the rotation of the gear 2 caused thereby is transmitted to the output shaft via the bellows. The number of teeth of gears 1 and 2 is nl and n2, respectively.
Then, for one rotation of gear 1, gear 2 rotates for nl - n2. Therefore, if nl = 100 and n2 = 99, gear 1
Gear 2 rotates once per revolution.
ギア１．２のピッチ円錐頂点は、理論的には第１図の如

と、結果として両者のピッチ円錐頂点間に若干のズレを
生じるのが避けられない。しかし実際のかみ合いは両ギ
アの歯すじの端末附近で行われるので、ズレが微かであ
る限り実際面で両者かみ合いの支障とならない。Theoretically, the apex of the pitch cone of gear 1.2 should overlap at one point on the input axis, as shown in FIG. However, if necessary, a slight deviation between these two vertices may be allowed in the design from the beginning. This is the case as follows. Theoretically, when a pair of face gears mesh, one of the gears becomes a concave gear, making gear cutting difficult. If the pitch cone angle is slightly modified to enable machining, it is inevitable that a slight deviation will occur between the two pitch cone vertices. However, since the actual meshing occurs near the ends of the tooth traces of both gears, as long as the misalignment is slight, it does not actually interfere with the meshing of both gears.
一般的には軸線方向に可ス菟性を有する蛇腹筒でトルク
を伝達するのであるから、伝導トルクの大きさは自ずか
ら限定される。また傾斜板にも大きな傾斜角度は許され
ない。このような制約はあるものの本発明では小型で大
きな減速比が得られる。Since torque is generally transmitted using a bellows tube that is flexible in the axial direction, the magnitude of the transmitted torque is naturally limited. Also, a large angle of inclination is not allowed for the inclined plate. Despite these limitations, the present invention allows a small size and a large reduction ratio to be obtained.
またギア１，２の傾斜角が４＼さいことと、ばね８の作
用とで、ギア１．２はバックラッシュ無しのかみ合いが
可能となる−
以上が本発明の特徴である。Furthermore, because the inclination angle of gears 1 and 2 is 4\ and the action of spring 8, gears 1 and 2 can mesh without backlash.These are the features of the present invention.
