An axial bearing device includes an annular electrical sheet arrangement having individual sheets which protrude radially outward. In addition, an electrical coil is provided in the axial bearing device and is inserted into the electrical sheet arrangement to generate a magnetic field in the electrical sheet arrangement. The electric sheet arrangement includes at least two concentric electrical sheet rings. All adjacent electrical sheets of each electrical sheet ring substantially abut at the inner circumference of the respective electrical sheet ring.

Axial bearing device having increased iron filling

The invention relates to a safety bearing for retaining a rotor shaft () of a machine (), wherein the safety bearing () comprises a first carrier body () rotating about a virtual geometric center line (M) and roller bodies (), wherein each roller body comprises a region () that is located between the center line (M) and the first carrier body (), wherein the roller bodies () are each connected in a rotatable manner to the first carrier body () via a shaft (). The invention creates a safety bearing () with which the likelihood of an occurrence of a backward-whirl is considerably reduced as compared to the safety bearings known from the prior art.

Safety bearing for retaining a rotor shaft of a machine

Disclosed is a retainer bearing () for retaining a rotor shaft of an electric machine. Said retainer bearing () comprises an outer bearing ring () and an inner bearing ring (). At least one gliding element () which is preloaded in a radial direction of the retainer bearing () is inserted between the outer bearing ring () and the inner bearing ring ().
