DAMPER STRUCTURE AND ROTATING MACHINE

摘要

Disclosed is a damper structure equipped with: a sleeve (11) which is provided on an axial end part (3a) extending outward of a bearing which supports an axle (3), and is provided on the outer circumference of the axial end part (3a); a housing (12) which is provided in the radial direction of the sleeve (11) and the axle (3), leaving an interval; and a moving part (13) which relatively moves the housing (12) and the sleeve (11) in the axial direction. In addition, a squeeze film (S (S1)) is formed between the mutually opposing outer circumferential surface (11a) of the sleeve (11) and inner circumferential surface (12b) of the housing (12), and the formation region for this squeeze film (S (S1)) can be changed.
