Abstract

【課題】モータを内蔵する部品の外径寸法を大型化することなく、大きなトルクを回転軸に得ること、軸受の支持剛性を高めること。 【解決手段】回転駆動対象部材11が固定される回転軸40、回転軸40の外周を囲み工作機械本体に着脱するハウジング30、ハウジング30と回転軸40との間に配置する軸受B1,B2、ハウジング30と回転軸40の間に設けられ回転軸40を回転して角度位置を割出す駆動手段を含み、駆動手段はハウジング30内で回転軸40の周りに同心円状に配置されたモータロータとモータステータの駆動モータM1,M2,M3を用いる工作機械用の角度割出し装置であり、複数の駆動モータM1,M2,M3を回転軸40の軸方向に離間して直列的に配置する。複数の軸受B1,B2を軸線方向に離間して配置し、そのうち最も回転駆動対象部材11側の軸受B2に、アキシアル、ラジアル方向の荷重を支持可能な複列形式のころ軸受を採用し、他の軸受の一つを複数の駆動モータM1,M2,M3の間に配置する。
