本発明は、トロコイド系歯形（エピトロコイド
平行曲線）を外歯歯車としたトロコイド系遊星歯
車機構（例えば「サイクロ減速機」（登録商標）、
内接形トロコイドモータ等）の改良に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a trochoidal planetary gear mechanism (for example, a "cyclo reducer" (registered trademark)), which uses a trochoidal tooth profile (epitrochoid parallel curve) as an external gear.
This relates to the improvement of internal trochoid motors, etc.).

には限界があつた。 Conventionally, in this type of gear mechanism, for example, in an internal gear 1 of a planetary gear reducer as shown in FIG. 1, as is clear from FIG. Arc tooth profile portion 3 of gear 1
Since the internal gear 1 and the external gear 2 are designed to mesh with each other, the internal gear 1 and the external gear 2 come into contact with each other at one contact point. Therefore, for the internal gear 1 made of circular arc teeth with the same diameter, the applied load is approximately fixed,
There is a limit to the miniaturization and high load of the planetary gear reducer, and the internal gear 11 of the internal trochoid motor as shown in FIG. Similar to the motor, the external gear 12, which has an epitrochoid parallel curve tooth profile, is simply an arrangement of circular arc tooth profile portions 13 that contact only at one point on the inner surface of a cylinder 14, and there is a limit to miniaturization and high pressure of the motor. It was hot.

絡線の円弧歯形部分外の一点でも外歯歯車が接触
するようにしたものである。 The present invention was created in order to solve the above-mentioned conventional problems, and when an external gear having a trochoidal tooth profile and an internal gear have an arcuate tooth profile, the present invention is inscribed in the internal gear and rotated eccentrically. By constructing an internal gear with a trochoidal inner envelope including a circular arc tooth profile drawn by an external gear, the contact point (meshing point) between the internal gear and the external gear effectively transmits the load. At this position, the external gear is made to come into contact with even one point outside the arcuate tooth profile portion of the envelope that constitutes the tooth profile of the internal gear.
以下、本発明を第３図〜第６図に示す遊星歯車
減速機につき説明する。 The present invention will be explained below with reference to the planetary gear reducer shown in FIGS. 3 to 6.

を歯形としたものである。 Figure 3 corresponds to the AA line cross section in Figure 1, and
5 and 6 are enlarged views of portions a, b, and c of FIG. 3, which are effective for load transmission. As is clear from these drawings, the internal gear 1' has adjacent arcuate tooth profile parts P and P, and an internal gear tooth profile part obtained as a mating tooth profile when the tooth profile of the external gear is an epitrochoid parallel curve. The tooth profile is a trochoid inner envelope synthesized from Q and including circular arc tooth profiles at both ends.

に作用する。 When such an internal gear 1' is meshed with an external gear 2 whose tooth profile is an epitrochoid parallel curve,
The contact point (meshing point) of the internal gear 1' and the external gear 2 is the contact point of the circular arc tooth profile portion P of the envelope that constitutes the tooth profile of the internal gear 1' at a position where the contact point (meshing point) of both is effective for load transmission. They mesh by two-point contact, which also has a contact point on the outside of the tooth-shaped portion Q. Since both of these two contact portions satisfy the mechanical tooth profile conditions of the gear, each contact point effectively acts on power transmission.

1' and an external gear 12 whose tooth profile is an epitrochoid parallel curve.

面強度を向上させることができる。 As described above, the present invention provides a two-point contact between the internal gear and the external gear in which the arcuate tooth profile portion of the trochoidal envelope tooth profile of the internal gear contacts with another tooth profile portion at a position effective for load transmission, and Since these two contact parts satisfy the mechanical tooth profile conditions of the gear, power is transmitted effectively, and the load acting on the tooth surface is distributed between the two, so the same power is transmitted. In this case, the load acting on the tooth surface can be reduced compared to the conventional type, and since the internal gear and external gear contact with almost the same tooth profile at the contact point that is effective for load transmission, the surface pressure is small. As a result, tooth surface strength can be improved.
したがつて、歯面の高負荷荷重化を図ることが
できるから、小型化、荷重伝達能力の向上、油圧
モータにあつては高圧化が可能となる。 Therefore, since it is possible to achieve a high load on the tooth surface, it is possible to reduce the size, improve the load transmission ability, and increase the pressure in the case of a hydraulic motor.
