Abrégé
(EN)

Two-stage or three-stage spur gear transmission having a single-piece housing which has a drive-input-side cover opening and a closing cover which closes off said cover opening, having a drive output shaft which supports a drive output gearwheel between two bearings, and having an intermediate shaft which supports an intermediate gearwheel, which is driven directly or indirectly by an input drive pinion, and an intermediate pinion, which meshes with the drive output gearwheel, and is mounted by means of two intermediate shaft bearings which are adjacent to the intermediate pinion. The two intermediate shaft bearings which are adjacent to the intermediate pinion are arranged in a drive-output-side chamber, which is preferably not undercut in the direction of the assembly opening, of the housing. A third intermediate shaft bearing is arranged in a bearing bore of the cover. Said cover is centered on said third intermediate shaft bearing along a parting joint which runs perpendicular to the axis direction.
