Abstract

A centrifugal separator structure is configured for cleaning of crankcase gases from an internal combustion engine. The centrifugal separator structure includes a separator rotor configured for rotation about a centre axis arranged inside a stationary housing. The separator rotor includes an axle member configured for connection to a shaft of a driving device. A stack of separation discs is supported on the axle member. The axle member is un-journaled inside the stationary housing when the centrifugal separator structure is separate from the driving device. Further, an assembly includes the centrifugal separator structure and a driving device.
