- G1100-1-6 Rotational Characteristics of Divided Type Ultra High Speed Hydrodynamic Grooved Journal Gas Bearings for Small Size Rotary Machines
抄録
Divided type φ6 herringbone grooved journal gas bearings have been developed to support high rotational speed practical rotor for a micro rotary machines such as a palmtop gas turbine generator. Critical mass of a rotor and radial clearance of journal and thrust bearings are designed to rotate over 800,000 rpm. Test journal bearings have radial clearance of 8 μm and mass of 4.2 gram. Roundness under the processed and the reassembled condition of the test radial bearing was measured by using 3-D CMM and was compared to verify repeatability of assembling bearing parts. The precision by reassembled condition was obtained 3.5 μm. Test of this bearings were carried out using a test rig. Spectra under the rotation and the orbit were measured by using displacement meter. Maximum rotor speed exceeded 804,000 rpm and the stably orbit was obtained.
