Title (EN) MOTOR-OPERATED VALVE
(FR) SOUPAPE MOTORISÉE
(JA) 電動弁
Abstract:
(EN) Provided is a motor-operated valve that has exceptional wear resistance while having minimal costs. This motor-operated valve comprises: a valve main body having a valve seat; a motor having a stator fixed to the valve main body and a rotor rotatably driven relative to the stator; a planet-gear-type reduction mechanism, which reduces the rotation of the rotor and transmits the rotation to an output gear; a valve body, which is capable of moving in an axial direction so as to move toward and away from the valve seat; and a feed screw mechanism, which converts the rotational movement of the output gear to axial movement of the valve body. The planet-gear-type reduction mechanism is provided with a sun gear linked to the rotor, a planet gear that meshes with the sun gear, a carrier that rotatably supports the planet gear, an annular ring gear that meshes with the planet gear, and a sliding member that comes into contact with an axial end of the sun gear. The output gear has a different number of teeth from the ring gear and meshes with the planet gear, and the sliding member is formed from a type of material different from the material of the sun gear.
(FR) L'invention concerne une soupape motorisée qui présente une résistance à l'usure exceptionnelle tout en ayant un faible coût. Cette soupape motorisée comporte : un corps principal de soupape ayant un siège de soupape ; un moteur ayant un stator fixé au corps principal de soupape et un rotor entraîné en rotation par rapport au stator ; un mécanisme de réduction de type à pignon satellite, qui réduit la rotation du rotor et transmet la rotation à un engrenage de sortie ; un corps de soupape, qui peut se déplacer dans une direction axiale de façon à se déplacer vers le siège de soupape et à s'éloigner de celui-ci ; un mécanisme de vis d'alimentation, qui convertit le mouvement de rotation de l'engrenage de sortie en un mouvement axial du corps de soupape. Le mécanisme de réduction de type à pignon satellite est pourvu d'un pignon planétaire relié au rotor, d'un pignon satellite qui engrène le pignon planétaire, d'un support qui porte de manière rotative le pignon satellite, d'une couronne annulaire qui engrène le pignon satellite et d'un élément coulissant qui vient en contact avec une extrémité axiale du pignon planétaire. L'engrenage de sortie possède un nombre différent de dents à partir de la couronne et engrène le pignon satellite, et l'élément coulissant est formé en un type de matériau différent par rapport au matériau du pignon planétaire.
(JA) コストを抑制しつつ、耐摩耗性に優れた電動弁を提供する。 電動弁は、弁座を有する弁本体と、前記弁本体に固定されたステータおよび前記ステータに対して回転駆動されるロータを有するモータと、前記ロータの回転を減速して出力ギヤに伝達する遊星ギヤ式減速機構と、前記弁座に対して接離するように軸線方向に移動可能となっている弁体と、前記出力ギヤの回転移動を前記弁体の軸線方向移動に変換する送りねじ機構と、を備えている。前記遊星ギヤ式減速機構は、前記ロータに連結された太陽ギヤと、前記太陽ギヤに噛合する遊星ギヤと、前記遊星ギヤを回転自在に支持するキャリヤと、前記遊星ギヤに噛合する環状のリングギヤと、前記太陽ギヤの軸線方向端に当接する摺動部材と、を備えている。前記出力ギヤは、前記リングギヤと異なる歯数を備え、且つ前記遊星ギヤに噛合しており、前記摺動部材は、前記太陽ギヤの素材とは異なる異種素材から形成されている。
