Title: Static pressure gas bearing
Inventor: YAMAZAKI SHIZUKA
IPC: F16C32/06
Filed: 1988-01-07
Abstract: PURPOSE:To increase bearing rigidity and damping coefficient by providing two row multiple grooves adjacent to both ends of a bearing, forming each gas feeding groove in circumferential and axial directions, and connecting gas feeding holes to the axial groove of each gas feeding groove. CONSTITUTION:When compressed gas is supplied through gas feeding holes 8, it flows through nozzles 9 into a bearing clearance 4 to from gas lubricating film in the bearing clearance 4 and a shaft 1 is kept non-contact against a bearing surface 3. Even if the shaft 1 is deviated when a load is applied, a high rigidity can be obtained since a relatively large pressure variation is produced at the areas excluding near the gas feeding holes 8 inside circumferential grooves 7, when the pressure in the circumferential grooves 7 is changed largely due to surface choke effect. Since a wide land 10 without groove can be provided between two rows of the gas feeding holes 8 and usable bearing clearance is small, the damping coefficient is improved greatly.
