Abstract

A gear train includes a housing, a shaft arranged in the housing, a gear wheel arranged on a first shaft shoulder, and first and second axial locks arranged on opposite sides of the gear wheel to axially secure the gear wheel. The second axial lock is attached to a second shaft shoulder having a diameter which is smaller than a diameter of the first shaft shoulder. A radial-axial sliding-contact bearing unit mounts the shaft in the housing and is attached to a third shaft shoulder disposed adjacent to the second shaft shoulder and defined by a diameter which is smaller than the diameter of the second shaft shoulder. A component attached to the shaft has a sliding surface for an axial sliding-contact bearing of the radial-axial sliding-contact bearing unit, with the second axial lock defining a running surface for the axial sliding-contact bearing of the radial-axial sliding-contact bearing unit.
