Abstract

The invention relates to a bearing arrangement and a bearing block (1) composed of a magnetic radial bearing (4) for the contact-less support of a rotor shaft (7) of a rotating machine (10), and composed of a safety bearing (5) for catching the rotor shaft (7). According to the invention, both bearings (4, 5) are connected to each other permanently and in an axially aligned manner, and are elastically suspended with regard to a bearing shield (11), a machine housing (12), or a foundation (20) of the rotating machine (10).

Description

technical field [0001] The invention relates to a two bearing arrangement consisting of a magnetic radial bearing and a captive bearing for the non-contact support and capture of a rotor shaft of a turbine having a power of 1000 kW or more, wherein the two bearings are accommodated axially aligned in in a common bearing housing. [0002] Furthermore, the invention relates to two bearing housings for turbomachines with a power of 1000 kW or more, wherein the individual bearing housings are arranged axially externally with respect to the turbine and have contactless bearings accommodated in a common bearing housing. A magnetic radial bearing for supporting the rotor shaft and a captive bearing for capturing the turbine rotor shaft are housed axially aligned in said common bearing housing. Background technique [0003] Such a bearing block as described above is disclosed by Japanese publication JP6335199A. [0004] A bearing housing with a bearing with practically zero longit...
