AIR FOIL BEARING WITH IMPROVED COOLING EFFICIENCY, CAPABLE OF IMPROVING COOLING EFFICIENCY BY APPLYING A DIRECT COOLING METHOD

摘要

PURPOSE: An air foil bearing with improved cooling efficiency is provided to minimize the decrease of the efficiency of a system by reducing a two dimensional blow for a cooling blow, thereby effectively supporting a super-high speed rotator.;CONSTITUTION: An air foil bearing with improved cooling efficiency comprises a bearing housing(160), a top foil(130), and an elastic foil. The bearing housing surrounds a rotary shaft. The top foil is installed between the rotary shaft and the bearing housing to be spaced from the rotary shaft at a predetermined space, thereby surrounding the rotary shaft. The elastic foil is interposed between the top foil and the housing and elastically transformed by being pushed by the top foil.;COPYRIGHT KIPO 2013
