Method of charging dynamic-pressure bearing device with lubricating fluid, and method of inspecting dynamic-pressure bearing device |
摘要 |
Method of charging dynamic-pressure bearing device with lubricating fluid. Preparatorily, lubricating fluid is put into a vacuum chamber and the chamber is vacuum-evacuated to subject the lubricating fluid to a degassing process. An appropriate quantity of fluid is dispensed in one end of the bearing gap, with the bearing device having been placed in a reduced-pressure ambient. In carrying out the dispensation, the pressure of the ambient is adjusted so as to be higher than the pressure during the degassing process. The method in this way prevents the lubricating fluid from frothing when it is being dispensed, and makes it possible to charge dynamic-pressure bearing devices with lubricating fluid without soiling the bearing-device surfaces with splashes or other contaminants.
