NettetIn a turbocharger hydrodynamic bearing system, the fluid (engine oil) not only lubricates the parts, preventing contact, but also controls the motion of the shaft and wheels under all running conditions. The hydrodynamic bearing system may use two “fully floating” journal bearings, which rotate at approximately half the speed of the shaft. Nettet1. jan. 2015 · PDF On Jan 1, 2015, M.V.S.
