Abstract

　工作機械用スピンドル駆動機構５は、外周面に螺旋状のねじ溝１１ａが形成されるねじ軸１１と、ねじ溝１１ａに対応する螺旋状のナット溝を内周面に備え、ねじ軸１１の軸心周りにおける回転運動にともなってねじ軸１１の軸線方向での往復運動が自在に構成されるボールねじナット１２と、ボールねじナット１２の外周面に固定設置されて界磁束発生源となる円筒形のインナーロータ２２と、インナーロータ２２に回転駆動力を与えるための回転磁界を発生する円筒形のアウターステータ２３とから構成される中空モータ２１と、一端側にアウターステータ２３が固定設置されるとともに、他端側に工作機械用のスピンドル５１が固定設置される筒形のケーシング３１と、ケーシング３１の軸線方向での往復運動を案内する外筒４１と、を備える。このような構成によって、工作機械に用いられる改良されたスピンドル駆動機構を得る。
