Abstract
Systems and methods for a sun gear, counter bearing parts, and bearing arrangements. The gear comprising a helical toothing and a first and a second thrust surface which are configured to axially support the sun gear at a first and a second counter thrust surface, respectively, wherein the first and the second thrust surface have a thrust generating geometry that is configured to build up a lubrication fluid film between the first thrust surface and the first counter thrust surface and between the second thrust surface and the second counter thrust surface during rotation of the sun gear. The counter bearing part for axially supporting a sun gear, and to a bearing arrangement for axially supporting a sun gear.
