静圧気体ジャーナル軸受の回転精度特性に関する基礎的研究 : 第3報,軸回転精度特性に及ぼす諸因子の影響

The run-out characteristics of a rotor with out-of-roundness error in its cross section, supported by an externally pressurized gas journal bearing, are investigated theoretically under the influence of some related factors, such as displacement of rotor due to an external load, form deviation (i. e., out-of-roundness error) of bearing bore, and circumferential pitch error in arrangement of supply holes. The features and magnitudes of the run-out of the rotor are discussed in relation to the number of lobes of form deviation of the rotor cross section and the number of supply holes, as well as other factors of machining errors.
