Embodiment Construction

[0024] figure 1 A cross-sectional view of a friction contact according to a preferred embodiment of the invention is shown. 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 relative to the second contact body 14 is rotational in this embodiment. Alternatively, the relative movement of the first contact body 12 relative to the second contact body 14 can eg be translational.

[0025] The first contact body 12 preferably has a substantially circular cross section. Alternatively, the first contact body 12 can, for example, have another suitable cross-sectional shape.

[0026] The second contact body 14 preferably has a substantially planar cross section. Arranged adjacent to the friction contact 10 is a lubricant path 16 leading to the friction contact 10 for supplying the fr...

Abstract

The invention relates to a device (1) with a frictional contact (10), wherein the frictional contact can be provided by a relative movement of the first contact body (12) relative to the second contact body (14). The part (10) provides a lubricant (17), wherein, through the lubricant (17) attached to the first contact body (12), the A liquid column of lubricant (17) is arranged in said lubricant path (16). Furthermore, the invention relates to a method for operating a device ( 1 ) with a friction contact ( 10 ).

Description

technical field [0001] The invention relates to a device with a friction contact. Furthermore, the invention relates to a method for operating a device with a friction contact. Background technique [0002] It is generally known that the presence of lubricating materials in frictional or tribological contacts brings significant advantages, such as lower friction, higher efficiency and lower thermal load, in many cases. The sufficient presence of lubricating material can either be achieved by the fact that, for example, lubricating material is essentially always present in the case of oil-immersed lubrication, or it can also be achieved by that the lubricating material supplied to the friction contact The volume flow is not less than the sum of the volume flow and losses (e.g. evaporation and / or chemical conversion) leaving the frictional contact, unless the net loss per time unit is so small that the initial amount of lubricating material is sufficient for the use of the co...
