FOUR-BEARING ROTOR SYSTEM

A bearing apparatus for reducing vibrations in a compressor shaft (17) carrying a rotating compressor (10) is provided. The bearing apparatus comprises a first bearing (14) for supporting the shaft (17) and a second bearing (13) spaced outboard from the first bearing (14) for producing a moment on t...

Beschreibung
Zusammenfassung:	A bearing apparatus for reducing vibrations in a compressor shaft (17) carrying a rotating compressor (10) is provided. The bearing apparatus comprises a first bearing (14) for supporting the shaft (17) and a second bearing (13) spaced outboard from the first bearing (14) for producing a moment on the shaft and additional damping counter to the direction of vibrations. L'invention concerne un appareil à paliers destiné à réduire les vibrations dans un arbre de compresseur (17) supportant un compresseur rotatif (10). Cet appareil à paliers comprend un premier palier (14) destiné à supporter l'arbre (17) et un second palier (13) espacé extérieurement par rapport au premier palier (14) en vue de la production d'un moment sur l'arbre et d'un amortissement additionnel contre les vibrations.
