Abstract
(EN) Provided is an elevator device which is equipped with a novel governor device that allows reliable meshing engagement between ratchet teeth of a ratchet wheel and a pawl of a fly weight. A pawl (28) meshing with ratchet teeth (17) of a ratchet wheel (16) is mounted on one side of the fly weight (18A), across a weight support shaft (27A) rotatably supporting the fly weight (18A), in order to cause the fly weight (18A) to move outward, and an inertia mass adjusting unit (33A) which makes the inertia mass of the fly weight equal to or smaller than that of the ratchet wheel (16) is formed on the other side of the fly weight (18A). Thus, it is possible to reliably mesh the ratchet teeth (17) of the ratchet wheel (16) with the pawl (28) of the fly weight (18A), and eliminate adverse effects, such as delays in the operation of an emergency stop device.
(FR) L'invention concerne un dispositif d'ascenseur équipé d'un nouveau dispositif régulateur qui permet une prise par engrènement fiable entre des dents triangulaires d'une roue à rochet et un cliquet d'une masselotte. Un cliquet (28) qui s'engrène avec les dents triangulaires (17) d'une roue à rochet (16) est monté d'un côté de la masselotte (18A), en travers d'un arbre support de poids (27A) qui supporte la masselotte (18A) en rotation, de manière à amener la masselotte (18A) à se déplacer vers l'extérieur, et une unité de réglage de masse d'inertie (33A) qui rend la masse d'inertie de la masselotte égale ou inférieure à celle de la roue à rochet (16) est formée de l'autre côté de la masselotte (18A). Il est ainsi possible d'engrener de manière fiable les dents triangulaires (17) de la roue à rochet (16) avec le cliquet (28) de la masselotte (18A), et d'éliminer les effets indésirables tels que des retards dans le fonctionnement d'un dispositif d'arrêt d'urgence.
(JA) ラチェットホイールのラチェット歯とフライウエイトの爪部との噛み合いを確実に行うことができる新規なガバナ装置を備えたエレベータ装置を提供することにある。 フライウエイト(18A)を飛開させるためにフライウエイト(18A)を回転可能に支持するウエイト支持軸(27A)を境として、フライウエイト(18A)の一方側に、ラチェットホイール(16)のラチェット歯(17)と噛み合う爪部(28)を取り付けると共に、フライウエイト(18A)の他方側に、フライウエイトの慣性質量をラチェットホイール(16)の慣性質量と同等、或いはこれより小さくする慣性質量調整部(33A)を形成した。これによって、ラチェットホイール(16)のラチェット歯(17)とフライウエイト(18A)の爪部(28)の噛み合いを確実にすることができ、非常止め装置の動作が遅れるといった悪影響をなくすことができるようになる。
