流体轴承装置
摘要：
本发明提供一种可以高精度地对轴承套相对于壳体进行定位的流体轴承装置。在壳体(7)的内周上，隔开固定有第一轴承套(8)及第二轴承套(9)。在轴承套(8)、(9)之间配置有由树脂构成的隔圈(10)。隔圈(10)的轴方向刚性比第一轴承隔圈(8)及第二轴承隔圈(9)的轴方向刚性小。因此，在第一轴承隔圈(8)及第二轴承隔圈(9)相对于壳体(7)定位固定后的状态下，隔圈(10)与轴承套(8、9)相比在轴向上被更大压缩。
摘要（英）：

A fluid bearing device where bearing sleeves are highly precisely positioned relative to a housing. A first bearing sleeve (8) and a second bearing sleeve (9) are fixed in an axially spaced relationship at the inner periphery of the housing (7). A resin spacer (10) is placed between the bearing sleeves (8, 9). The spacer (10) has lower axial rigidity than the first bearing sleeve (8) and the second bearing sleeve (9). Accordingly, the spacer (10) is more axially compressed than the bearing sleeves (8, 9) when the sleeves (8, 9) are positioned and fixed relative to the housing (7).
