【０００１】
【発明の属する技術分野】
この発明はモータと減速機部が一体に形成されたギヤードモータに関するものである。
【０００２】
【従来の技術】
モータ部と減速機部が一体に形成された例えば垂直取付形のギヤードモータの構成を図３に示す。図において、１はモータ、１ａはモータ１の端子箱、２はモータ１に減速機部を連結するブラケット、５は減速機部、６は減速歯車が組み込まれるギヤーケース、６ａはギヤーケース６内の潤滑油を排出する排油口、７は減速歯車により減速されて回転する出力軸、８は潤滑油を給油する給油口、９はギヤーケース６内の潤滑油の油面を指示する油面計、１０はブラケット２とギヤーケース６を結合する固定ボルトである。
【０００３】
図３の垂直取付形のギヤードモータは、ギヤードモータが駆動する装置へ取り付けた後に、給油口８から潤滑油を油面計９の所定の位置まで給油し、給油口８には、運転時の温度上昇による内部圧力の上昇を抑制するために空気通路を設けたブリーザが取り付けられている。
【０００４】
【発明が解決しようとする課題】
上記のように従来のギヤードモータは、モータ部１、減速機部５が同じ構成の場合であっても、水平取付形と垂直取付形の場合で潤滑油量が異なり、油面の位置、方向も異なり、油面計９および給油口８は、水平取付形、垂直取付形それぞれに適する位置に配置されており、ギヤーケース６は水平取付形と垂直取付形で形状が異なり、ギヤーケース６のほか各部品が異なるため部品の種類が多く、生産性はあまりよくないという問題点があった。
【０００５】
この発明は、上記問題点を解決するためになされたものであり、ギヤードモータの油面計の位置を水平取付、垂直取付のいずれの場合にも適正油面が指示される位置に油面計を取り付けた構成とし、水平取付形と垂直取付形のそれぞれが同一部品で構成できるギヤードモータを提供することを目的とする。
【０００６】
【課題を解決するための手段】
この発明の請求項１に係るギヤードモータは、水平取付時の減速機部の潤滑油の適正油面と、垂直取付時の適正油面が交差する位置のギヤーケースの側面に油面計を取り付けた構成としたものである。
【０００７】
この発明の請求項２に係るギヤードモータは、請求項１の構成の油面計を垂直取付用の適正油面位置と、水平取付用の適正油面位置が交差する位置のギヤーケースの両側面に取り付けた構成としたものである。
【０００８】
この発明の請求項３に係るギヤードモータは、ギヤーケースには２つの給油口を設け、一方の給油口は水平取付時においてギヤードモータの上方から下方に給油できるように構成されるとともに、他方の給油口は垂直取付時においてギヤードモータの上方から下方に給油できるように構成されたものである。
【０００９】
【発明の実施の形態】
実施の形態１．
実施の形態１のギヤードモータの構成を図１に示す。２０はモータ部、２１はモータ軸であり、一端側の先端に減速機部の第一歯車２１ａが形成されている。２２は減速機部に連結するフランジ２２ｆが設けられたブラケットであり、フランジ２２ｆのギヤードモータが水平取付された状態の上方となる位置に給油口２２ａが設けられている。
【００１０】
３１は減速歯車が収容されたギヤーケースであり、ギヤードモータが水平取付の横形の潤滑油の適正油面位置と、垂直取付の縦形の適正油面位置とが交差する位置の側部に油面計取付座３１ａと、水平取付された状態の上方位置であり、かつ垂直取付された状態の適正油面位置の側部に給油口３１ｂ、および垂直取付された状態と水平取付された状態のいずれの状態においても下方となる位置（図示の左下方）に排油口３１ｃが設けられている。ブラケット２２のフランジ２２ｆに設けられた給油口２２ａ、ギヤーケース３１に設けられた油面計取付座３１ａおよび給油口３１ｂは、同一寸法、同一構造に形成されている。
【００１１】
３２は第二の歯車、３３は中間部に第三の歯車３３ａが形成され、その一方に第二の歯車３２が嵌装された回転軸、３４は第四の歯車、３５は中間部に第四の歯車３４が嵌装され、一端が外部に突出した出力軸である。４１は油面計、４２ａは外気と通気するように構成したブリーザ、４２ｂは給油口３１ｂを封止する封止栓である。封止栓４２ｂは水平取付時の給油口２２ａにも取り付けられる。油面計４１、ブリーザ４２ａ、封止栓４２ｂのそれぞれの装着部は、油面計取付座３１ａ、給油口２２ａ、給油口３１ｂのいずれにも装着できるように同一に形成されている。３０は減速機部であり、ギヤーケース３１、第二の歯車３２、回転軸３３、第四の歯車３４、出力軸３５、油面計４１、ブリーザ４２ａおよび封止栓４２ｂで構成されている。
【００１２】
図１のギヤードモータの水平取付状態を図２（ａ）、垂直取付状態を図２（ｂ）に示す。ギヤードモータが水平取付される場合は、油面計取付座３１ａには油面計４１が取り付けられ、給油口２２ａには封止栓４２ｂが取り付けられ、給油口３１ｂには潤滑油の給油後にブリーザ４２ａが取り付けられる。
【００１３】
ギヤードモータが垂直取付される場合は、油面計取付座３１ａには油面計４１、給油口３１ｂには封止栓４２ｂが取り付けられ、給油口２２ａには潤滑油の給油後にブリーザ４２ａが取り付けられる。
【００１４】
このように構成されたギヤードモータは、油面計４１の油面指示が水平取付の場合にも、垂直取付の場合にも適正油面を指示する状態であり、給油口は水平取付の場合、垂直取付の場合のそれぞれの取付状態において、上方となる給油口、すなわち水平取付の場合は給油口３１ｂ、垂直取付の場合は給油口２２ａから給油し、給油後にブリーザ４２ａを取り付け、給油しない給油口には封止栓４２ｂを取り付けておくことにより対応できるものであり、ギヤードモータとしては同一構造で水平取付、垂直取付のいずれの場合にも対応できる構成である。したがって、ギヤーケース等の部品が垂直取付、水平取付の区別がなく、部品の種類が少なく、生産性の高いギヤードモータとなる。
【００１５】
実施の形態２．
実施の形態２はギヤードモータの両側から油面が確認できる構成としたものである。その方法は、図１の構成のギヤーケース３１の水平取付の場合の適正油面位置と、垂直取付の場合の適正油面位置が交差する位置のギヤーケース３１の両側の側部に油面計取付座３１ａを設けてそれぞれに油面計４１を取り付け、水平取付時の給油口３１ｂは、垂直取付時の適正油面位置でかつ油面計取付座３１ａの反対側の位置の側部に設けて油面計４１が取り付けできる構成とし、垂直取付時には油面計４１を取り付けたものである。
【００１６】
このように複数の油面計４１を取り付けた構成とすると、水平取付用の場合は２方から油面の確認ができ、垂直取付の場合はギヤードモータの３方から油面の確認ができる構成となり、取付位置によって一方がブラインドされる場合にも油面が確認できる構成となる。
【００１７】
【発明の効果】
この発明の請求項１に係るギヤードモータは、水平取付用の適正油面位置と垂直取付用の適正油面位置とが交差する位置のギヤーケースの側面に油面計を取り付けた構成としたので、垂直取付用と水平取付用が同一構造に構成され、水平取付、垂直取付の区別なく生産できる生産性の高いギヤードモータが構成できる。
【００１８】
この発明の請求項２に係るギヤードモータは、請求項１の構成の油面計を水平取付用の適正油面位置と、垂直取付用の適正油面位置が交差する位置のギヤーケースの両側の側面に取り付けた構成としたので、取付位置の一方がブラインドされる場合にも油面が確認できる構成となる。
【００１９】
この発明の請求項３に係るギヤードモータは、ギヤーケースには２つの給油口を設け、一方の給油口は水平取付時においてギヤードモータの上方から下方に給油できるように構成されるとともに、他方の給油口は垂直取付時においてギヤードモータの上方から下方に給油できるように構成されたので、ギヤードモータとしては同一構造で水平取付、垂直取付のいずれの場合にも対応できる構成となる。
