Abstract
A high-speed turbomachine includes a magnetic bearing () and a retainer bearing for mounting the rotor. The retainer bearing is embodied as a sliding bearing () and encompasses a bearing shell () at the stator end, a bearing shaft () at the rotor end, and an intermediate bushing () between the bearing shell () and the bearing shaft (). The intermediate bushing () is spaced apart from both the bearing shaft () and the bearing shell () by a circular gap (). The intermediate bushing () is rotatable relative to the bearing shell () and the bearing shaft (). As a result of this design, the sliding bearing () is provided with two pairs of sliding surfaces, onto which all occurring dynamic forces are distributed such that wear is significantly reduced, thus allowing sliding bearings to be used as retainer bearings in a magnetically mounted high-speed turbomachine.
