Abstract
A rotary machine provides a stator having a stator casing, and a rotor shaft having a rotational axis and supported in the stator casing by at least one radial magnetic bearing. The rotary machine further provides an axial mechanical thrust bearing being disposed proximate a radial surface of one end of the rotor shaft, the axial mechanical thrust bearing, including a rolling element located on the rotational axis of the rotor shaft.
Claims11
A rotary machine comprising:
- a stator having a stator casing, and
- a rotor shaft having a rotational axis (X-X) and supported in the stator casing by at least one radial magnetic bearing, and
- an axial mechanical thrust bearing being disposed proximate a radial surface of one end of the rotor shaft, the axial mechanical thrust bearing having a rolling element located on the rotational axis (X-X) of the rotor shaft, wherein
- the axial mechanical thrust bearing is in axial contact with one end of the rotor shaft and provides a bearing mounted between a stator plate and one end of the rotor shaft and designed to support the rotor weight, the stator plate being supported by the rolling element.
