Abstract
In this paper, a new type of double-row admission gas journal bearing with circular slot restrictors is proposed and the static characteristics are investigated. The gap of the slot region of this bearing can be made only be supplying pressure into the bearing because the bearing part corresponding to the slot region is elastically deformed. This bearing, therefore, does not need a shim prepared corresponding to the gap of the slot region. Furthermore, this bearing can possess easily the maximum load capacity in a very small bearing clearance of less than 10μm, since a very narrow gap of the slot region is easily obtained by varying the thickness of the elastically deformed part. The experimental results are in good agreement with the theoretical results obtained by the analysis for the conventional double-raw admission gas journal bearing with circular slot restrictors.
