In currently working seismic ACROSS (Accurately Controlled Routinely Operated Signal System) transmitters, an unbalanced rotor with large eccentric mass, which generates elastic waves, is supported by roller bearings. With such a type of bearings, bearing losses are so large that heat generation and cooling system become serious problems. To solve these problems, a trial test ACROSS transmitter using hydrostatic gas bearings are designed, made and carried out. The test results show that the hydrostatic gas bearings safely support a largely unbalanced rotor with eccentric mass. In this paper, a new type of hydrostatic journal gas bearings with asymmetric bearing area specially proposed for a largely unbalanced rotor are analyzed and tested. It is shown that hydrostatic asymmetric journal gas bearings have large load capacity for a largely unbalanced rotor and low gas flow rate compared to the conventional hydrostatic symmetric journal gas bearings. |
