Abstract
オイルポンプロータに発生する油圧が微小でかつこのロータを駆動するトルクが変動した場合においても、騒音発生を確実に抑制すること。 基礎円ｂｉ上を転がる第１外転円Ｄｉ及び第１内転円ｄｉによって創成されるサイクロイド曲線に基づいて形成された歯数ｎ枚のインナーロータ１０を形成し、基礎円ｂｏ上を転がる第２外転円Ｄｏ及び第２内転円ｄｏによって創成されるサイクロイド曲線に基づいて形成された歯数ｎ＋１枚のアウターロータ２０を形成した際に、前記各円の直径をφｂｉ，φＤｉ，φｄｉ，φｂｏ，φＤｏ，φｄｏとするとき、φｂｉ＝ｎ・（φＤｉ＋φｄｉ），φｂｏ＝（ｎ＋１）・（φＤｏ＋φｄｏ）、φＤｉ＋φｄｉ＝２ｅ、あるいはφＤｏ＋φｄｏ＝２ｅであり、かつφＤｏ＞φＤｉ，φｄｉ＞φｄｏ，（φＤｉ＋φｄｉ）＜（φＤｏ＋φｄｏ）を満たして各ロータを構成する。
