摘要： PURPOSE:To hold a bearing in parallel with the rotary shaft and keep fluid film at the damper part in a uniform thickness by providing a movement adjustment means for correction of misalignment of the bearing with the rotary shaft at the coupling part of a bearing support spring with the housing. CONSTITUTION:At the coupling part of a bearing support spring 9 with the housing 2 is provided a movement adjusting means 10 composed of adjusting bolts 13 and 15 for movement of the bearing 3 and bearing support spring 9 in the radial and axial directions, respectively, and a bolt 17 for fixation of a flange 12 to the housing 2 after completion of the movement adjustment. The thickness of fluid film at the damper part 6 is uniformed by moving the bearing 3 and spring 9 by means of adjustment of the amount of driving in the bolt 13 upon loosening the bolt 17, and a gap between the rotary shaft 1 and bearing 3 can be kept uniform by adjusting the amount of driving in the bolt 15.

摘要： PURPOSE:To try to carry out easily and accurately positioning of tool holder, constructing to move spindle itself foreward and backward, moving adjusting rod foreward or backward. CONSTITUTION:A thrust bearing 7 of gas bearing body 1 received a thrust plate 5 of the spindle 2 is supported to move to the direction of thrust to inner surface 8 and opening 9 of cover 6 of bearing body 1. An air supply hole 10, 11 for pressurized gas is provided in the bearing body 1 and cover 6 respectively, the air supply hole 10 is connected to the throttle 12 on the outer surface of the spindle 2, simultaneously air supply hole 11 is connected to the throttle 14 of thrust bearing 7. While an arm 19 is installed on the bearing body 1, a lever 21 is installed to it through a spherical surface bearing 20, disc 25 is installled on the projection 22 of thrust bearing 7, a ball is inserted between the lever 21 and the disc, the end of adjusting rod 27 supported to move foreward and backward to the bearing body 1 is touched to the free end of the lever 21.
