Abstract
In an apparatus for cleaning of gases a centrifugal rotor is supported by two bearings, in which it is rotatable about a rotational axis. The two bearings are lubricated by means of an oil mist, which is generated in a space, when oil is sprayed against a turbine wheel supported by the rotor. Whereas the bearing, which is situated nearest said space, is lubricated by oil mist present in the space, the second bearing is lubricated by oil mist being conducted to it through a central channel in the centrifugal rotor.
Claims13
An apparatus for cleaning of a gas from particles suspended therein comprising:
- a centrifugal rotor for rotation of the gas, which centrifugal rotor is rotatable about a rotational axis in two bearings arranged axially spaced from each other and arranged to be charged with lubricant during operation of the centrifugal rotor,
- the centrifugal rotor surrounds a channel, which extends axially through the rotor and through which a mist of said lubricant is movable from a space near the centrifugal rotor into contact with one of said bearings;
- and
- wherein the centrifugal rotor has a rotatable central shaft, which is rotatable with the rotor.
