Abstract
The invention relates to a centrifugal separator for separation of at least two components of a fluid mixture which have different densities. The centrifugal separator comprises a rotor arranged for rotation about a vertical axis of rotation (R) and having a rotor wall which surrounds a separating chamber within the rotor, with an inlet adapted to feeding the fluid mixture into the rotor's separating chamber, and at least one outlet adapted to discharging outwardly from the rotor a component separated from the fluid mixture. A rotor shaft supports the rotor and is drivably connected to a motor (M) for rotation of the rotor about the axis of rotation (R). A hub is provided outside the rotor, and the hub and the rotor shaft are arranged to be connected together from the outside of the rotor by means of a lockable and releasable fastening which is configured to lock the rotor shaft relative to the hub in both a torque-transmitting and an axial force-transmitting way.
