A rotating machine (1) has a rotor (10), a stator (20), a radial bearing (30) arranged for supporting radial forces between the rotor (10) and the stator (20) by mechanical contacts and a bearing housing (21). The bearing housing (21) is provided in the stator (20) or the rotor in direct mechanical contact with the radial bearing (30). The rotating machine (1) further comprises a thermal energy exchanger (40), arranged in the bearing housing (21), and a thermal control means (50). The thermal energy exchanger (40) is capable of providing both heat and cold. The thermal control means (50) is arranged to control the thermal energy exchange during operation of the rotating machine (1). The rotating machine (1) is typically a large machine, such as a refiner. A method for vibration control of a rotating machine (1) comprises measuring of properties related to vibration properties is also disclosed.

L'invention concerne une machine tournante (1) comprenant un rotor (10), un stator (20), un palier radial (30) disposé pour supporter des forces radiales entre le rotor (10) et le stator (20) par contacts mécaniques, et un logement de palier (21). Le logement de palier (21) est disposé dans le stator (20) ou le rotor en contact mécanique direct avec le palier radial (30). La machine tournante (1) comprend en outre un échangeur d'énergie thermique (40), disposé dans le logement de palier (21), et des moyens de contrôle thermique (50). L'échangeur d'énergie thermique (40) est capable de fournir à la fois de la chaleur et du froid. Les moyens de contrôle thermique (50) sont disposés pour commander l'échange d'énergie thermique pendant le fonctionnement de la machine tournante (1). La machine tournante (1) est typiquement une machine grande, telle qu'un raffineur. L'invention concerne également un procédé pour le contrôle de vibrations d'une machine tournante (1), le procédé comprenant la mesure de propriétés liées aux propriétés de vibration.
