Embodiment Construction

[0039] The liquid metal sliding bearing according to the invention comprises at least one first bearing component 1 and at least one second bearing component 2 which are connected to each other in a friction fit. According to the invention, at least one sealing ring 3 made of a flexible material is arranged between the first bearing component 1 and the second bearing component 2 .

[0040] in press Figure 1 to Figure 3 The liquid metal sliding bearings shown in the embodiments respectively comprise exactly one first bearing component 1 and one second bearing component 2, wherein between the first bearing component 1 and the second bearing component 2 there is provided only one with toughness material, such as a sealing ring 3 made of graphite. The sealing ring 3 accordingly has a rectangular cross section and is arranged concentrically to the longitudinal axis 4 of the shaft 5 . In the illustrated embodiments, the first bearing member 1 and the second bearing member 2 are d...

Abstract

The embodiments relate to a liquid metal journal bearing including at least one first bearing part and at least one second bearing part. The bearing parts are non-positively connected to one another. Additionally, at least one sealing ring made of a ductile material is arranged between the first bearing part and the second bearing part. With a liquid metal journal bearing of this type, the escape of liquid metal is prevented, even under heavy loading. The liquid metal journal bearing is therefore suitable, for example, for installation in an X-ray generator.

Description

technical field [0001] The invention relates to a liquid metal sliding bearing. Background technique [0002] Liquid metal plain bearings work almost frictionlessly, run very quietly while emitting low noise, and guarantee extremely effective heat dissipation. Such liquid metal plain bearings are therefore used, for example, in x-ray tubes of rotary anodes, in particular high-power x-ray tubes. [0003] For this reason, the sliding bearing surface of the liquid metal sliding bearing must have high heat resistance and good thermal conductivity. In addition, the sliding bearing surfaces must have good wetting capabilities. Usually the material of liquid metal sliding bearings uses molybdenum-based materials. Special steels and ceramics are also used as materials for liquid metal plain bearings. [0004] Liquid metal plain bearings consist of several components, which must run into each other very precisely. In the X-ray tube of the rotary anode, the liquid metal sliding b...
