Abstract

【課題】製造時間を短縮することができ、中子を容易に取り出すことができる内歯車の製造方法および金属ガラス製の内歯車を提供する。 【解決手段】細長い筒状の鋳型１１の内部に、外歯車形状に形成された鋳型と同一長のカーボン製の中子１２を、鋳型１１の長さ方向に沿って鋳型１１との間に空隙を有するよう配置する。金属材料１の融点より高い温度下で、鋳型１１と中子１２との空隙に、圧力をかけて溶融した金属材料１を注入する。金属材料１を鋳型１１および中子１２とともに、金属材料１の臨界冷却速度以上で急冷して固化させる。金属材料１の固化後、中子１２を粉砕または溶解して除去する。金属材料１が固化して形成された長尺の内歯車２を、所定の長さで切断して複数に分割する。
