A Study of Three Lobe Bearing Design for Turbo Compressor

터보 콤프레셔용 3로브 베어링의 설계에 관한 연구

Three lobe bearings for turbo compressor which appear inner pad damage after field operation has been analysed and redesigned in order to remove the problems. Pre-load and clearance between the pad and journal of the bearing were changed as design parameters from that of the original ones considering suitable maximum temperature and maximum pressure of the bearings. New hearings were manufactured corresponding the redesign. And vibration and temperature were measured according to the API specifications.
