The concept of the invention is based on a machine housing with a bearing housing, the bearing seat of which is connected to a housing wall of the machine housing by a bearing housing wall provided with ribs (42, 43) and is subjected to radially directed forces (11, 44). The proposal is made that the bearing housing wall possess at least one ring shaped annular rib (42) which at least partially encompasses the bearing seat in an area (21), the angle (α) of inclination of which, relative to its original unloaded condition, would change itself to the greatest extent under load ( 11). Further proposed is that a plurality of additional ribs ( 43) run transverse to the annular rib (42). Thereby, with a relatively small consumption of material, a good shape-retention is achieved. In addition, a tilting of the bearing seat and the bearing is held to a lesser extent than is the case of conventional bearing housing structures. By the use of shell shaped bearing housings, the bearing housing wall is characterized by a more intensive curvature in the more heavily stressed area (21) than is the case in the area (22) which lies diametrically (with respect to the bearing axis) opposite.

What is claimed is: 1. A machine housing having a bearing housing (1, 14), a bearing housing wall (3, 16) provided with ribs (7, 8, 42, 43) affixing a bearing seat ( 2, 15) to a housing wall of the machine housing, and the bearing housing wall (3, 16) is subject to axial and radial directed loads (10, 11) during operation; wherein the bearing housing wall (3, 16) has at least one ringlike annular rib (7, 42) formed therein which eccentrically encompasses the bearing seat (2, 15), the at least one ringlike annular rib (7, 42) is located in an area (9, 21) which lies, with reference to a bearing rotational axis (4), diametrically opposite to an area which has a greatest change of an angle of inclination (α ), whereby at least one of the annular rib (7, 42) and incremental parts ( 45) proximal to a bearing block (5, 17) which surround the bearing seat (2, 15) lie in an area connected to said bearing block and a plurality of additional ribs (8, 43 ) extend transversely to the annular ribs (7, 42). 2. The machine housing according to claim 1, wherein at least one of the annular rib (7, 42) and the incremental parts (45) are substantially elliptical in shape. 3. The machine housing according to claim 2, wherein the annular rib (7, 42) comprises a plurality of straight incremental parts (45) which are located between the transversely running ribs (8, 43). 4. The machine housing according to claim 1, wherein the bearing housing wall (16) is constructed of a shell-shape and, during operation, the bearing housing (16) is subjected to a radial directed principal load (11), whereby the bearing housing wall (16), in an absent of the load, has an area (21) with a cross-section of a more intense curvature than the area (22) which, relative to the bearing axis (4), is diametrically opposed thereto. 5. The machine housing according to claim 4, wherein an annular rib (42) extends to an outer border of an incremental part (26) of the bearing housing wall (16) which runs essentially parallel to the bearing plane (23). 6. The machine housing according to claim 1, wherein the bearing housing (14) is a bearing cover bolted to the machine housing and the transversely running ribs (43) structurally join bolt eyes (19) with the bearing housing (14). 7. The machine housing according to claim 6, wherein the bearing housing (14) is a bearing cover of a tapered bearing differential drive. 8. The machine housing according to claim 1, wherein the bearing housing (14) offset to a side of the radial principal load (11), is subjected to a smaller radial load ( 44), which forms an angle (γ) with the principal load (11), and the annular rib (42) not only encompasses an area in which the angle of inclination (α) changes the most under the principal load ( 11), but also encompasses an area with the angle of inclination (α) which changes the most, in relation to its original condition, under the smaller load (44).
