Title (EN) SPINDLE DEVICE
(FR) DISPOSITIF D'ARBRE ROTATIF
(JA) スピンドル装置
Abstract:
(EN) This spindle device (10) is provided with: a rotating shaft (12) provided with a plurality of turbine blades (11) that extend in the circumferential direction; a housing (20) that houses the rotating shaft (12); and a gas bearing (40) provided on the housing (20) and that, through the supply of a gas, floats and supports the rotating shaft (12) with respect to the housing (20) in a contactless manner, wherein the rotating shaft (12) rotates due to the gas being jetted onto the plurality of turbine blades (11). The plurality of turbine blades (11) overlap the gas bearing (40) in the axial direction. As a result, a flat configuration in which the length in the axial direction is short is provided whereby miniaturization and weight reduction can be achieved.
(FR) L'invention concerne un dispositif d'arbre rotatif (10) qui est pourvu : d'un arbre de rotation (12) ayant une pluralité de pales de turbine (11) qui s'étendent dans la direction périphérique ; d'un boîtier (20) qui loge l'arbre rotatif (12) ; d'un palier à gaz (40) disposé sur le boîtier (20) et qui, par l'intermédiaire de l'alimentation en gaz, fait flotter et soutient l'arbre rotatif (12) par rapport au boîtier (20) selon un mode sans contact, l'arbre rotatif (12) tournant sous l'effet du gaz qui est projeté sur la pluralité de pales de turbine (11). La pluralité de pales de turbine (11) chevauchent le palier à gaz (40) dans la direction axiale. Par conséquent, une configuration plane dans laquelle la longueur dans la direction axiale est courte est fournie, grâce à laquelle une miniaturisation et une réduction de poids peuvent être obtenues.
(JA) スピンドル装置(10)は、複数のタービン羽根(11)が円周方向に亙って設けられる回転軸(12)と、該回転軸(12)を収容するハウジング(20)と、該ハウジング(20)に取り付けられ、気体の供給により、ハウジング(20)に対して回転軸(12)を非接触で浮上支持する気体軸受(40)と、を備え、複数のタービン羽根(11)に気体が噴出されることにより回転軸(12)を回転駆動する。複数のタービン羽根(11)は、該気体軸受(40)と軸方向においてオーバーラップする。これにより、軸方向の長さが短い扁平な構成とし、小型化及び軽量化を実現可能である。
