Title (EN) BALL-RECIRCULATING TUBE AND BALL SCREW DEVICE
(FR) TUBE DE RECIRCULATION DE BILLES ET DISPOSITIF DE VIS À BILLES
(JA) ボール循環チューブ、ボールねじ装置
Abstract:
(EN) A ball-recirculating tube (4), which forms a pathway connecting two separated sites of a rolling path in a ball screw device (1) and recirculates balls (6), wherein outer end parts (4a, 4b), which form outer ends and are disposed, when the tube is attached to the ball screw device (1), at positions that are farthest from the central axis line of a threaded shaft (2) in the radial direction, are provided with an adjustment margin for adjusting the distance from the central axis line of the threaded shaft (2) to the outer ends. As a result, parts to be fitted on the nut and the ball-recirculating tube (4) can be easily attached.
(FR) L'invention concerne un tube (4) de recirculation de billes qui forme un trajet reliant deux sites séparés d'un chemin de roulement dans un dispositif (1) de vis à billes et qui entraîne les billes (6) en recirculation, des parties terminales extérieures (4a, 4b), qui forment des extrémités extérieures et qui sont placées, lorsque le tube est relié au dispositif (1) de vis à billes, à des positions qui sont plus éloignées de la ligne d'axe central d'un arbre fileté (2) dans la direction radiale, étant pourvues d'une marge de réglage afin de régler la distance entre la ligne d'axe central de l'arbre fileté (2) et les extrémités extérieures. Par conséquent, des pièces à monter sur l'écrou et le tube (4) de recirculation de billes peuvent être facilement attachés.
(JA) ボールねじ装置(1)の転動路の離隔した2箇所を結ぶ経路を形成し、ボール(6)を循環させるボール循環チューブ(4)であって、ボールねじ装置(1)に取り付けた際にねじ軸(2)の中心軸線から径方向に最も離れた位置に配置される外端を形成する外端部(4a、4b)が、ねじ軸(2)の中心軸線から外端までの距離を調整するための調整しろを備える。これにより、ナット及びボール循環チューブ(4)に外嵌する部品を容易に取り付けることができる。
