Title
(EN) TABLE ROTATION DEVICE AND MACHINE TOOL
(FR) DISPOSITIF DE ROTATION DE TABLE ET MACHINE-OUTIL
(JA) テーブル回転装置、および、工作機械
Abstract
(EN) This table rotation device is provided with: a bearing assembly that has a fixed ring, a movable ring rotatable relative to the fixed ring about the axis of rotation, and a rolling element placed between the fixed ring and the movable ring; a table support member that is fixed to the movable ring and supports the table; a support block that is fixed to the fixed ring and rotatably supports the table support member about the rotation axis; and a cooling block that defines at least a portion of a cooling flow path through which cooling liquid can pass. The cooling block is fixed to the fixed ring or the support block so that the cooling block is in contact with both the fixed ring and the support block.
(FR) L'invention concerne un dispositif de rotation de table pourvu : d'un ensemble palier qui a une bague fixe, une bague mobile pouvant tourner par rapport à la bague fixe autour de l'axe de rotation et un élément roulant placé entre la bague fixe et la bague mobile ; d'un élément de support de table qui est fixé à la bague mobile et supporte la table ; d'un bloc de support qui est fixé à la bague fixe et supporte de manière rotative l'élément de support de table autour de l'axe de rotation ; et d'un bloc de refroidissement qui définit au moins une partie d'un trajet d'écoulement de refroidissement à travers lequel du liquide de refroidissement peut passer. Le bloc de refroidissement est fixé à la bague fixe ou au bloc de support, de telle sorte que le bloc de refroidissement soit en contact avec à la fois la bague fixe et le bloc de support.
(JA) テーブル回転装置は、固定リング、固定リングに対して回転軸まわりに相対回転可能な可動リング、および、固定リングと可動リングとの間に配置される転動体を有する軸受アセンブリと、可動リングに固定され、テーブルを支持するテーブル支持部材と、固定リングに固定され、テーブル支持部材を回転軸まわりに回転可能に支持する支持ブロックと、冷却液が通過可能な冷却流路の少なくとも一部を規定する冷却ブロックとを具備する。冷却ブロックは、固定リングおよび支持ブロックの両方に接触するように、固定リングまたは支持ブロックに固定される。
