Title (EN) FLUID PRESSURE DRIVE UNIT
(FR) UNITÉ D'ENTRAÎNEMENT À PRESSION DE FLUIDE
(JA) 流体圧駆動ユニット
Abstract:
(EN) In the present invention, a fluid pressure drive unit provides working fluid to a fluid pressure actuator and drives the same. The fluid pressure drive unit is provided with the following: a fluid pressure pump that sucks in and ejects the working fluid; an electric motor for rotating and driving the fluid pressure pump; a power transmitting mechanism for transmitting power between the rotation axle of the fluid pressure pump and the rotation axle of the electric motor; and a circulation mechanism that is driven by the power transmitted by the power transmitting mechanism, and that is for cooling the electric motor by introducing fluid for lubrication that is inside of the power transmitting mechanism.
(FR) La présente invention porte sur une unité d'entraînement à pression de fluide qui achemine un fluide de travail à un actionneur à pression de fluide et entraîne ce dernier. L'unité d'entraînement à pression de fluide comporte les éléments suivants : une pompe à pression de fluide qui aspire et refoule le fluide de travail ; un moteur électrique destiné à faire tourner et à entraîner la pompe à pression de fluide ; un mécanisme de transmission d'énergie destiné à transmettre l'énergie entre l'axe de rotation de la pompe à pression de fluide et l'axe de rotation du moteur électrique ; et un mécanisme de circulation qui est entraîné par l'énergie transmise par le mécanisme de transmission d'énergie et qui est destiné à refroidir le moteur électrique en introduisant du fluide lubrifiant qui est à l'intérieur du mécanisme de transmission d'énergie.
(JA)  流体圧駆動ユニットは、流体圧アクチュエータに作動流体を供給して駆動するものである。前記流体圧駆動ユニットは、作動流体を吸い込んで吐出する流体圧ポンプと、前記流体圧ポンプを回転駆動する電動機と、前記流体圧ポンプの回転軸と前記電動機の回転軸との間で動力を伝達する動力伝達機構と、前記動力伝達機構が伝達する動力によって駆動され、当該動力伝達機構内の潤滑用流体を導いて前記電動機を冷却する循環機構と、を備える。
