Abstract

PURPOSE:To obtain a reliable bearing adapted for ultrahigh speed revolution by using an air bearing and a rolling bearing jointly. CONSTITUTION:The inner ring of a rolling bearing 12 is fitted to a shaft 1 to be rotated by a motor. A sleeve 11 is fitted to the outer ring of this rolling bearing 12. An air bearing 7 is arranged around this sleeve 11 with a fixed gaseous film 10 between. To this shaft 1, a blower 2 is provided to generate high pressure gas, which is supplied to the air bearing 7. Meanwhile, a bearing temperature monitor (a temperature detecting element 8 and a detector 13) is fitted up on the air bearing 7, and a controller 14 is provided to stop the driving motor by that signal. In this construction, since the rolling bearing 12 is operated at the time of low speed revolution (starting and stopping), the bearing is prevented from injuries. When some abnormality happens, the bearing can be easily protected by motor stop.
