Abstract: Gearbox with a shaft bearing (33) which is accommodated in a bearing eye (7) adjacent to an assembly opening (2), the bearing eye (7) being slotted towards the assembly opening (2). The assembly opening (2) and the bearing (33) are covered by a cap (36). The cap (36) contains a bore (35) for accommodating the major part of the axial extent of the bearing (33). The bearing bore of the bearing eye (7) is, by this means, substantially relieved of the support function and is only used for centring the bearing and the cap, whereas the support of the bearing takes place by means of the cap. The gearbox casing can contain an intermediate wall (8) between the assembly opening (2) and the output-end wall (13) for supporting the output shaft. So as to make it possible to assemble the output-end gearwheel (14) without a special assembly opening, the intermediate wall (8) is lopped at the level of the support (18) of the output shaft.

Abstract: A gear housing having an assembly orifice closed by a cover supporting a cover shaft extending centrally into the housing and supporting a pinion in the housing. A gear shaft having mounted thereon a gear wheel interacting with said pinion is journalled in the housing with one of its bearings being positioned between the gear wheel and the cover. Locating devices comprising a surface of revolution concentric to the bearing is provided for securing the exact position of the housing and the cover relative to one another which is necessary for a proper interaction between the gear wheel and the pinion.
