Embodiment Construction

[0035] Unless stated to the contrary, identical reference numerals in the illustrated figures denote identical or functionally identical elements, components or parts.

[0036] figure 1 A cross-sectional view of a device with a friction contact according to a preferred embodiment of the invention is shown.

[0037] The device 1 preferably has a friction contact 10 with a first contact body 12 and a second contact body 14 . The first contact body 12 is preferably adjustable relative to the second contact body 14 . The relative movement of the first contact body 12 and the second contact body 14 is rotational in the present embodiment. As an alternative, the relative movement of the first contact body 12 and the second contact body 14 can eg be translational.

[0038] The first contact body 12 preferably has a substantially circular cross section. The second contact body 14 preferably has a substantially flat cross section. Arranged adjacent to the friction contact 10 is a ...

Abstract

The invention relates to a device (1) with a friction contact (10), wherein the lubricant supply (16) has a lubricant path (18) with a first region (18a) and with A second zone (18b) in which the heat (W) released in the first zone can be absorbed by the lubricant (17), in which it can be output by the lubricant The heat (W) absorbed by the agent (17). The invention also relates to a method for operating a device with frictional contact.

Description

technical field [0001] The invention relates to a device with a friction contact. The invention also relates to a method for operating a device with a friction contact. Background technique [0002] For cooling the contact or frictional contact, convective cooling mechanisms are known, such as heat sinks, in which the heat output to the surrounding fluid, generally air, is improved by a larger surface. Furthermore, it is known to be suitable for use as heat pipes, which transport a relatively large heat flow from a hot place to a cold place. These heat pipes are based on the principle of evaporation / condensation and must therefore be completely closed. In general, cooling circuits are known in very different applications, which include the return of a cooling medium. [0003] In the frictional contact, the frictional power is largely converted into heat. This leads to a temperature increase of the contact partners (friction contact and lubricating substance), wherein thi...
