Title (EN) BEARING AND MEDICAL DEVICE
(FR) PALIER ET DISPOSITIF MÉDICAL
(JA) 軸受および医療デバイス
Abstract:
(EN) Provided are: a bearing in which a gap is ensured between an inner ring and outer ring, the gap being capable of being utilized as a flow passage for fluid, an object, etc.; and a medical device. This bearing (10) has a plurality of rolling bodies (40) arranged between an inner ring (20) and an outer ring (30). The outer ring (30) is provided with a raceway surface (31) on which the rolling bodies (40) roll, and receiving sections (23) for rotatably receiving the rolling bodies (40) are provided to the inner ring (20) at positions facing the raceway surface (31).
(FR) La présente invention concerne un palier dans lequel un espace est garanti entre un anneau interne et un anneau externe, l’espace étant susceptible d’être utilisé comme passage d’écoulement de liquide, d’un objet, etc. ; et un dispositif médical. Ce palier (10) présente une pluralité de corps de roulement (40) disposés entre un anneau interne (20) et un anneau externe (30). L’anneau externe (30) est doté d’une surface de chemin de roulement (31) sur laquelle les corps de roulement (40) roulent, et des sections de réception (23) servant à recevoir de manière à pouvoir tourner les corps de roulement (40) sont disposées au niveau de l’anneau interne (20) à des positions faisant face à la surface de chemin de roulement (31).
(JA) 内輪と外輪の間に隙間を確保し、この隙間を流体や物体等の流路として利用できる軸受および医療デバイスを提供する。 内輪(20)および外輪(30)の間に複数の転動体(40)を有する軸受(10)であって、外輪(30)に転動体(40)が転がる軌道面(31)が設けられ、内輪(20)の軌道面(31)と対向する位置に転動体(40)を回転可能に収容する受け部(23)が設けられている。
