A drive for adjusting devices includes gear elements mounted in a gear housing which includes at least two plates that can be secured to each other by plug connectors. The connectors are also configured as supporting joints that absorb the forces of the gear elements. A method for assembling the gear housing includes prefitting the gear elements and the housing plates by fitting the housing plates together about the gear elements with plug connectors, holding the housing plates with a holding device with sufficiently light holding forces so that the housing plates can be aligned when the gear elements are turned, turning the gear elements for the purpose of aligning bearing points of the gear elements, and securing the position of the gear elements and the housing plates relative to each other by permanently fixing the position of the housing plates in all three-dimensional directions through action on the plug connectors.
