Publication number: 20230184256Abstract: A compressor includes a tilting pad bearing supporting a rotating shaft in a casing. The tilting pad bearing includes a bearing pad being in sliding contact with an outer circumferential surface of the rotating shaft and a pivot supporting the bearing pad in a swingable manner. The casing includes a groove portion having an annular shape recessed in the axial direction and extending in the circumferential direction, and a connection portion configured to connect an inner circumferential region of an inner side in the radial direction with respect to the groove portion to an outer circumferential region of the outer side in the radial direction with respect to the groove portion. The connection portion overlaps with the pivot as viewed from the axial direction.Type: ApplicationFiled: December 2, 2022Publication date: June 15, 2023Applicant: MITSUBISHI HEAVY INDUSTRIES COMPRESSOR CORPORATIONInventors: Toru Yoshimune, Takashi Oda
