Description
直動軸受２３は、レール２３１及びリニアブロック（移動体）２３２を含む。直動軸受２３は、レール２３１に案内されて転動体が回転することにより、当該転動体を有するリニアブロック２３２が直線運動をする機械要素部品である。リニアブロック２３２は、直方体状をなし、予めレール２３１に組み付けられている。１本のレール２３１に、２つのリニアブロック２３２が組み付けられている。図１は、レール２３１の軸方向からリニアブロック２３２を描いているため、奥側のリニアブロック２３２は隠れている。
なお、１本のレール２３１に組み付けられるリニアブロック２３２の数は、１つでもよいし、３つ以上でもよい。
また、直動軸受２３は、圧縮空気を介してリニアブロック２３２がレール２３１に案内されるものでもよい。
The linear motion bearing 23 includes a rail 231 and a linear block (moving body) 232. The linear motion bearing 23 is a machine element component in which the linear block 232 having the rolling element linearly moves when the rolling element rotates while being guided by the rail 231. The linear block 232 has a rectangular parallelepiped shape and is assembled to the rail 231 in advance. In one rail 231, two linear blocks 232 are assembled. Since FIG. 1 depicts the linear block 232 from the axial direction of the rail 231, the linear block 232 on the back side is hidden.
Note that the number of linear blocks 232 assembled to one rail 231 may be one, or may be three or more.
Further, the linear motion bearing 23 may be one in which the linear block 232 is guided to the rail 231 through compressed air.
他方、上方に噴出した加圧空気は下側のエアパッド２７及び垂下部材２９を介して上軸ベース２６を下方へ引っ張る力を上軸ベース２６及び垂下部材２９の接合面付近（スラスト軸受２５と上側のエアパッド２７との中間位置）に発生させる。上軸ベース２６を下方へ引っ張る当該力は、スラスト軸受２５の上面端部を支点にして、スラスト軸受２５と上側のエアパッド２７との中間位置における上軸ベース２６部分を下方へ曲げるように変形させる。その結果、図６に示す上側のエアパッド２７の取り付け及び加圧空気の噴出により上方へ反った上軸ベース２６の外側は下方へ撓み、上軸ベース２６の全体形状はより平坦な方向へ変形する。よって、上軸ベース上に載置したレール３２１の変形を抑えることができる。結果として、上部ステージ部３０の移動精度の低下を抑えることができる。 On the other hand, the pressurized air jetted upward has a force that pulls the upper shaft base 26 downward via the lower air pad 27 and the hanging member 29 in the vicinity of the joint surface between the upper shaft base 26 and the hanging member 29 (the thrust bearing 25 and the upper side). Of the air pad 27). The force pulling the upper shaft base 26 downward is deformed so that the upper shaft base 26 portion at the intermediate position between the thrust bearing 25 and the upper air pad 27 is bent downward with the upper end of the thrust bearing 25 as a fulcrum. . As a result, the outer side of the upper shaft base 26 warped upward by the attachment of the upper air pad 27 and the ejection of pressurized air shown in FIG. . Therefore, deformation of the rail 321 placed on the upper shaft base can be suppressed. As a result, it is possible to suppress a decrease in the movement accuracy of the upper stage unit 30.
