Title (EN) ROTOR FOR PUMP, AND INTERNAL GEAR PUMP USING SAME
(FR) ROTOR POUR POMPE ET POMPE À ENGRENAGE INTERNE UTILISANT CE ROTOR
(JA) ポンプ用ロータとそれを用いた内接歯車式ポンプ
Abstract: front page image
(EN)In the present invention the tooth profile of an inner rotor (2) is formed by the envelope of a group of arcs of a trajectory circle (C) the center of which is on a trochoidal curve (TC) described by a point separated from the center of the rolling circle by a distance corresponding to the amount of eccentricity of both rotors, with the diameter d2 of the trajectory circle (C) being constant to one point between the crest of the tooth tip and the crest of the tooth bottom of the inner rotor, and changing from that one point such that the diameter d2B at the crest of the tooth bottom is larger than the diameter d2T at the crest of the tooth tip.
(FR)Dans la présente invention, le profil de dent d'un rotor intérieur (2) est formé par l'enveloppe d'un groupe d'arcs d'un cercle de trajectoire (C) dont le centre se trouve sur une courbe trochoïdale (TC) décrite par un point qui est espacé du centre du cercle de roulement d'une distance correspondant à l'excentricité des deux rotors, le diamètre d2 du cercle de trajectoire (C) étant constant jusqu'à un certain point, entre la crête de la pointe de dent et la crête du creux de dent du rotor intérieur, et changeant à partir de ce certain point de telle sorte que le diamètre d2B à la crête du creux de dent est supérieur au diamètre d2T à la crête de la pointe de dent.
(JA)インナーロータ2の歯形が、基礎円上を所定径の転円が滑らずに転がり、この転円の中心から両ロータの偏心量相当量離れた点が描くトロコイド曲線TC上に中心を有する軌跡円Cの円弧群の包絡線によって形成されており、軌跡円Cの直径dが、インナーロータの歯先頂点と歯底頂点の間の1点までは一定で、前記1点から変化してインナーロータの歯先頂点における直径d2Tよりも歯底頂点における直径d2Bが大きくなるようにした。
