| 摘要 |
The present invention relates to a hydrostatic bearing comprising a foot part supporting a load-carrying unit, a head part, and body part forming a lower chamber and an upper chamber. A lower member is supported by the load- carrying unit and arranged inside the lower chamber. An upper member is controllable by a pressurizing fluid and arranged inside the upper chamber. The lower member is controllably moveable along a central axis of the hydrostatic bearing between a retracted state, where the lower member is distanced from the upper member, and an extended state, where the lower member is in contact with the upper member. The hydrostatic bearing according to the present invention possesses advantages of both a conventional slave bearing and a conventional master bearing. |
