Bearing Device With Squeeze Film Damper, and Centrifugal Compressor

Abstract

The present invention is to provide a bearing device with a squeeze film damper, which is able to obtain high vibration stability, and to provide a centrifugal compressor including the bearing device. A bearing device (1) with a squeeze film damper according to the present invention includes a plurality of pads (3) that constitute a bearing surface supporting a rotating shaft (2), a bearing housing (4) that accommodates the pads (3), a housing (5) that is located outside the bearing housing (4) in a radial direction, and a plurality of squeeze film damper parts (7) arranged in a circumferential direction at a clearance (11) between the bearing housing (4) and the housing (5). Each of the squeeze film damper parts (7) includes a plurality of elastic bodies (6) that repel a radial force. The plurality of elastic bodies (6) are set such that overall stiffness is different between in a vertical direction and in a horizontal direction.
