ボールねじを構成するナットの内径側ねじ溝形成部の表面硬化を行うためのボールねじの熱処理方法であって、前記ナットの外径側に配置された第1のコイルに低周波電流を流し、該ナットをその外径側から加熱する工程と、所定時間の経過後に前記ナットの内径側に配置された第2のコイルに高周波電流を流し、該ナットのねじ溝形成部の温度が焼入れ温度に達するまで該ナットをその内径側から加熱する工程と、前記ナットの内径側からの加熱終了後、前記ナットを冷却して焼入れする工程とを有することを特徴とするボールねじの熱処理方法。  A heat treatment method of a ball screw for performing surface hardening of an inner diameter side thread groove forming portion of a nut constituting a ball screw, wherein a low frequency current is passed through a first coil disposed on an outer diameter side of the nut, A process of heating the nut from its outer diameter side, and a high-frequency current is passed through the second coil disposed on the inner diameter side of the nut after a lapse of a predetermined time, and the temperature of the thread groove forming portion of the nut becomes the quenching temperature. A method of heat-treating a ball screw, comprising: heating the nut from the inner diameter side until reaching the inner diameter; and cooling and quenching the nut after heating from the inner diameter side of the nut. ボールねじを構成するナットの外周に配置される第1のコイルと、前記ナットの内周に配置された第2のコイルと、前記第1のコイルと前記第2のコイルとにそれぞれ独立して対応する周波数の交番電流を供給する制御手段とを備えることを特徴とするボールねじの熱処理装置。  The first coil disposed on the outer periphery of the nut constituting the ball screw, the second coil disposed on the inner periphery of the nut, and the first coil and the second coil independently. And a control means for supplying an alternating current having a corresponding frequency. ねじ溝を有するねじ軸と、ねじ溝を有するナットと、前記ねじ軸及びナットのねじ溝間に介在する多数のボールとを備えるボールねじにおいて、前記ナットが中炭素合金鋼でなり、請求項1に記載の熱処理方法で形成されてなる表面硬化層を有することを特徴とするボールねじ。2. A ball screw comprising: a screw shaft having a screw groove; a nut having a screw groove; and a plurality of balls interposed between the screw shaft and the screw groove of the nut, wherein the nut is made of medium carbon alloy steel. A ball screw comprising a hardened surface layer formed by the heat treatment method described in 1. ねじ溝を有するねじ軸と、ねじ溝を有するナットと、前記ねじ軸及びナットのねじ溝間に介在する多数のボールとを備えるボールねじにおいて、前記ナットが中炭素合金鋼でなり、請求項2に記載の熱処理装置により形成されてなる表面硬化層を有することを特徴とするボールねじ。3. A ball screw comprising a screw shaft having a screw groove, a nut having a screw groove, and a plurality of balls interposed between the screw shaft and the screw groove of the nut, wherein the nut is made of medium carbon alloy steel. A ball screw comprising a surface hardened layer formed by the heat treatment apparatus described in 1.
