Problems solved by technology

[0026] Furthermore, measures that are in principle possible, for example, that the heat from the liquid metal-slide bearing is completely isolated or that the load of the liquid metal-slide bearing is reduced by reducing the rotational speed of the portal, these measures cause medical imaging systems less effective

Embodiment Construction

[0045] exist figure 1 and figure 2 The liquid metal plain bearing shown in has at least one first bearing part 1 with an outer diameter 11 and at least one second bearing part 2 with an inner diameter 21 .

[0046] The first bearing part 1 and the second bearing part 2 are produced, for example, from molybdenum.

[0047] The first bearing part 1 is designed as a stationary bearing part and forms an inner bearing, the opposite second bearing part 2 is designed as a rotating bearing part and comprises a first sleeve 3 and a second sleeve 4 which are locked against each other in a rotationally fixed manner. connect. The first sleeve 3 and the second sleeve 4 thus form a rotating bearing sleeve.

[0048] In the liquid metal-sliding bearing assembly, the inner bearing 1 (stationary bearing part) is arranged in the first sleeve 3 (part of the rotating bearing part 2) and afterward the second sleeve 4 (rotating bearing part 2 part) is connected to the first sleeve 3 in a torsion...

Abstract

The present invention relates to a liquid metal-sliding bearing comprising at least one first bearing member (1) having an outer diameter (11) and at least one second bearing member (2) having an inner diameter (21), wherein at least one bearing gap (5; 6) filled with liquid metal (7) is formed between said bearing members (1, 2). At least one of said bearing members (1, 2) according to the invention comprises at least one means for locally increasing the carrying capacity. This type of liquid metal-sliding bearing has a high working safety and a long service life in the event of a high heat and mechanical load which occurs for a long time.

Description

technical field [0001] The invention relates to a liquid metal-sliding bearing. Background technique [0002] A liquid metal plain bearing of this type is known, for example, from DE 103 18 194 A1. In known cases, the liquid metal plain bearing is arranged in the roentgen ray tube and serves for the support of the rotating anode. [0003] The liquid metal plain bearing works virtually wear-free, has great smoothness while generating low noise and thus ensures good heat dissipation from the mounted component (rotating anode). [0004] The liquid metal plain bearing comprises at least one first bearing part with an outer diameter and at least one second bearing part with an inner diameter. The first bearing part is a stationary bearing part, whereas the second bearing part forms a rotating bearing part. To meet high requirements such as high heat resistance of liquids, good thermal conductivity and good wettability, molybdenum-based materials are often used for bearing part...
