发明名称 HYDROSTATICALLY SUPPORTING DEVICE FOR SLIDE
摘要 A slide (20) guided on a guiding member (10) has at least one sliding surface (21) in slidable engagement with a guiding surface (11) of the guiding member (10). The at least one sliding surface (21) is formed with an elongate supply groove (31) extending in the sliding direction of the slide and is also formed with a plurality of hydrostatic pressure pockets (22) arranged in the sliding direction of the slide. The slide (20) is formed therein with passages (32) which respectively provide fluid communications of the hydrostatic pressure pockets (22) with the elongate supply groove (31), and a plurality of throttle elements (35) are respectively fitted in the passages (32) at portions of the same opening to the hydrostatic pressure pockets (22). A supply passage (33) connected to an oil supply (34) is formed in the guiding member (10) and at the guiding surface (11), opens to the elongate supply groove (31) for always communicating with the elongate supply groove (31) irrespective of the sliding position of the slide (20).
