Problems solved by technology

[0026] Further fundamentally possible measures, such as for example a complete removal of the heat from the liquid metal plain bearing or a reduction of the load on the liquid metal plain bearing by reducing the rotational speed of the gantry, would lead to a reduction in the efficiency of the medical imaging system

Embodiment Construction

[0052] exist figure 1 neutralize figure 2 The liquid metal sliding bearing shown in respectively includes a first bearing part 1 and a second bearing part 2 .

[0053] The first bearing part 1 and the second bearing part 2 are produced, for example, from molybdenum.

[0054] The first bearing part 1 is designed as a stationary bearing part and forms an inner bearing, whereas the second bearing part 2 is designed as a rotating bearing part and comprises a first sleeve 3 and a second sleeve 4 which are rotationally fixed connected to each other. The first sleeve 3 as well as the second sleeve 4 thus form a rotating bearing sleeve.

[0055] In the assembly of liquid metal plain bearings, the inner bearing 1 (stationary bearing part) is inserted into the first sleeve 3 (part of the rotating bearing part 2) and followed by the second sleeve 4 (part of the rotating bearing part 2). part) is connected to the first sleeve 3 in a rotationally fixed manner.

[0056] After assembly...

Abstract

The invention relates to a liquid metal plain bearing which comprises at least one first bearing part (1) with an outer diameter and at least one second bearing part (2) with an inner diameter, wherein at least one bearing gap (5; 6) filled with a liquid metal (7) is arranged between the bearing parts (1, 2). According to the invention, at least one recess (11, 12; 21, 22) is arranged in at least one bearing part (1; 2). Such a liquid metal plain bearing also has a high operating safety as well as a long service life, even in the case of a high thermal and mechanical load occurring over a long period of time.

Description

technical field [0001] The invention relates to a liquid metal sliding bearing. Background technique [0002] Such a liquid metal plain bearing is known, for example, from document DE 103 18 194 A1. In known cases, liquid metal sliding bearings are arranged in roentgen ray tubes and serve to support the rotating anode. [0003] The liquid metal plain bearing runs virtually wear-free, has a high level of quietness of operation while at the same time generating low noise, and moreover ensures good heat dissipation from the supported components (rotating anode). [0004] The liquid metal sliding 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, for example, a stationary bearing part, whereas the second bearing part forms a rotating bearing part. In order to meet high requirements such as, for example, high thermal tensile strength and good thermal conductivity as we...
