Abstract

A bearing assembly for supporting a helical-wheel shaft of a helical planetary gear, in particular an adjustment device in vehicles for adjusting two mutually adjustable vehicle parts, wherein the helical-wheel planetary gear is a helical-wheel shaft with a helical-gear toothing, which shaft is rotatably mounted about a helical-wheel shaft axis, and a planetary carrier comprising at least three helical planetary gears, each rotatably mounted in the planetary carrier about a planetary gear axis, and each having a planetary gear toothing, wherein the helical gear planetary axes extend obliquely to the helical-wheel shaft axis, and the bearing assembly for supporting the helical gear shaft has a first bearing section and a second bearing section, wherein the first bearing section consists of an axial and radial bearing, and the second bearing section consists of helical-wheel planetary gears, wherein the planetary gear toothing in the second bearing section meshes with the helical-gear toothing.
