In this figure, reference numeral 1 is a main gear, which is fixed to one rotating shaft (not shown). Reference numeral 2 denotes an auxiliary gear having the same number of teeth as that of the main gear 1, which is rotatably provided on the rotary shaft. A coil spring 3 is interposed between the gears 1 and 2 and teeth of a mating gear that mesh with each other are sandwiched by the teeth of the gears 1 and 2 urged by the spring force of the spring 3. , Eliminate the backlash between meshing gears. In the figure, 4 is a snap ring, 5 is a long hole bored in the main gear 1, 6 is a pin implanted in the main gear 1, and 7 is a pin implanted in the auxiliary gear 2. The pin 7 is inserted through the elongated hole 5. And, the above-mentioned panel 3 is hung on these pins 6 and 7.

ところで、前記図３について説明したものでは、部品点数が多く、かつ構成が 複雑であるという課題があった。 この考案は、上記に鑑み、部品点数が少なく、かつ構成が簡単な、バックラッ シュ防止機構に用いるギヤを提供することを目的とするものである。 By the way, in the above description with reference to FIG. 3, there is a problem that the number of parts is large and the configuration is complicated. In view of the above, the present invention has an object to provide a gear used for a backlash prevention mechanism having a small number of parts and a simple structure.
【０００４】[0004]
上記の課題を解決するための、この考案は、 主ギヤ部と補助ギヤ部とこれらを結合するランナとが一体に樹脂成形されたギ ヤであって、前記主ギヤ部と補助ギヤ部とは同心軸上に所定の間隔を隔てて配設 され、かつ同一歯数の歯部を有し、これらの歯部は互いに回転方向に所定の位相 差を有することを特徴とするバックラッシュ防止機構に用いるギヤである。 In order to solve the above-mentioned problems, the present invention is a gear in which a main gear portion, an auxiliary gear portion, and a runner for connecting them are integrally resin-molded, and the main gear portion and the auxiliary gear portion are A backlash prevention mechanism characterized in that the teeth are arranged on a concentric shaft at a predetermined interval and have the same number of teeth, and these teeth have a predetermined phase difference in the rotational direction. This is the gear used.
【０００５】[0005]
上記のように構成されたギヤでは、主ギヤ部と補助ギヤ部との間に介装された ランナの弾性力により、相手ギヤの歯部を、前記主ギヤと補助ギヤの歯部にて挟 持し、噛合する前記相手ギヤと主ギヤ部・補助ギヤ部との間のバックラッシュが 解消される。 In the gear configured as described above, the tooth portion of the mating gear is sandwiched between the tooth portions of the main gear and the auxiliary gear by the elastic force of the runner interposed between the main gear portion and the auxiliary gear portion. Backlash between the mating gear that is held and meshed with the main gear portion / auxiliary gear portion is eliminated.
【０００６】[0006]
以下に、この考案の一実施例を図１について説明する。 図１（ａ）において、１０は主ギヤ部、１１は補助ギヤ部、１２はランナであ り、これらは一体に樹脂成形されている。前記主ギヤ部１０と補助ギヤ部１１と は同心軸上に所定の間隔を隔てて配設され、かつ同一歯数の歯部を有する。そし て、これらの歯部は互いに回転方向に所定の位相差γを有している。 上記図１（ａ）のように構成されたギヤをバックラッシュ防止機構に用いると きには、図１（ｂ）に示すように、ランナ１２の弾性力により付勢された前記主 ギヤ部１０と補助ギヤ部１１の歯部にて、伝達用相手ギヤ１３の歯部を挟持する 。これにより、相手ギヤ１３と主ギヤ部・補助ギヤ部との間のバックラッシュが 解消される。 尚、上記主ギヤ部１０は一方の回転軸（図示せず）に固定し、補助ギヤ部１１ は前記回転軸に回転自在取り付ける。また、前記相手ギヤ１３は他方の軸（図示 せず）に固定する。 An embodiment of this invention will be described below with reference to FIG. In FIG. 1A, 10 is a main gear portion, 11 is an auxiliary gear portion, and 12 is a runner, and these are integrally resin-molded. The main gear portion 10 and the auxiliary gear portion 11 are arranged on a concentric shaft at a predetermined interval and have tooth portions with the same number of teeth. Then, these tooth portions have a predetermined phase difference γ in the rotational direction. When the gear configured as shown in FIG. 1A is used in the backlash prevention mechanism, as shown in FIG. 1B, the main gear portion 10 urged by the elastic force of the runner 12 is used. And the tooth portion of the auxiliary gear portion 11 holds the tooth portion of the mating transmission gear 13. As a result, backlash between the mating gear 13 and the main gear portion / auxiliary gear portion is eliminated. The main gear portion 10 is fixed to one rotating shaft (not shown), and the auxiliary gear portion 11 is rotatably attached to the rotating shaft. The mating gear 13 is fixed to the other shaft (not shown).
【０００７】 上記実施例では、図１（ｃ）に断面して示すように、２本のランナ１２を用い たが、図２に示すようにコイルバネ状の一本のランナ１４を用いてもよい。In the above embodiment, two runners 12 are used as shown in a sectional view in FIG. 1C, but one coil spring-shaped runner 14 may be used as shown in FIG. .
