Title (EN) AIR TURBINE DRIVE SPINDLE
(FR) BROCHE D'ENTRAÎNEMENT DE TURBINE À AIR
(JA) エアタービン駆動スピンドル
Abstract:
(EN) Provided is an air turbine drive spindle configured so that an increase in pressure within a through-hole can be prevented. This spindle is provided with a rotating shaft (1) and an outer peripheral member (housing assembly (2), cover (5), and nozzle plate (6)). The rotating shaft (1) has a through-hole (17) formed therein. The outer peripheral member includes a bearing sleeve (4) surrounding at least a part of the outer peripheral surface of the rotating shaft (1). The outer peripheral member includes a gas supply section and a gas discharge hole (11). The spindle is provided with a second gas discharge section (first gas discharge hole (25) and first gas flow passage (26)). The second gas discharge section is independent of the gas discharge hole (11) and connects to the outside from a gas discharge space (20).
(FR) L'invention concerne une broche d'entraînement de turbine à air configurée de telle sorte qu'une augmentation de pression à l'intérieur d'un trou traversant peut être empêchée. Cette broche est pourvue d'un arbre rotatif (1) et d'un élément périphérique externe (ensemble boîtier (2), couvercle (5), et plaque de buse (6)) L'arbre rotatif (1) comporte un trou traversant formé (17) en son sein. L'élément périphérique externe comprend un manchon de palier (4) entourant au moins une partie de la surface périphérique externe de l'arbre rotatif (1). L'élément périphérique externe comprend une section d'alimentation en gaz et un trou de décharge de gaz (11). La broche est pourvue d'une seconde section de décharge de gaz (premier trou de décharge de gaz (25) et d'un premier passage d'écoulement de gaz (26)) La seconde section de décharge de gaz est indépendante du trou de décharge de gaz (11) et se connecte à l'extérieur à partir d'un espace de décharge de gaz (20).
(JA) 貫通穴内部の圧力上昇を抑制することが可能なエアタービン駆動スピンドルを提供する。スピンドルは、回転軸(1)と、外周部材(ハウジングアッシ(2)、カバー(5)およびノズル板(6))とを備える。回転軸(1)には貫通穴(17)が形成されている。外周部材は、回転軸(1)の外周面の少なくとも一部を取り囲む軸受スリーブ(4)を含む。外周部材は、給気部と排気孔(11)とを含む。スピンドルは、第2排気部(第1排気穴(25)および第1気体流路(26))を備える。第2排気部は、排気孔(11)とは独立し、排気空間(20)から外部へ繋がる。
