A bevel gear mechanism, especially a bevel spur-gear mechanism having one or more gear mechanism stages, including a gear mechanism housing that surrounds the gear mechanism stages, and a motor cage, which is connected via a spacer flange to the gear mechanism housing, and is connected to an electric motor. The drive side shaft of the bevel gear mechanism stage is supported in a flanged bushing. Spacer flange and drive side end wall of the gear mechanism housing have a common bore. The common bore extends around the flanged bushing of the drive side shaft. The flanged bushing has a cylindrical outer surface that centers the gear mechanism housing, the spacer flange and the flanged bushing. Furthermore, the flanged bushing, the spacer flange and the drive side end wall are interconnected by screws.

What I claim is: 1. A bevel gear mechanism having one or more gear mechanism stages, comprising: a gear mechanism housing that surrounds the gear mechanism stages; a motor cage, wherein said motor cage is adapted to be connected to an electric motor; a spacer flange, wherein said motor cage is connected to said gear mechanism housing via said spacer flange; a flanged bushing, wherein a drive side shaft of a bevel gear mechanism stage is supported in said flanged bushing, further wherein said spacer flange and a drive side end wall of said gear mechanism housing are provided with a common bore that extends around said flanged bushing, and wherein said flanged bushing has a cylindrical outer surface that is adapted to center said gear mechanism housing, said spacer flange and said flanged bushing; and screws that interconnect said flanged bushing, said spacer flange and said drive side end wall of said gear mechanism housing, wherein said spacer flange is provided with a central bearing plate that extends around said flanged bushing, and wherein a thickness of said bearing plate is greater than a thickness of said drive side end wall of said gear mechanism housing and is greater than a thickness of said spacer flange beyond said bearing plate. 2. A bevel gear mechanism according to claim 1, wherein an end of said flanged bushing is provided with a flange that rests against said spacer flange on a side remote from said gear mechanism housing. 3. A bevel gear mechanism according to claim 1, wherein said spacer flange and said bearing plate are reinforced by ribs. 4. A bevel gear mechanism according to claim 1, wherein an outer wall of said motor cage, and said spacer flange, are provided laterally with flattened portions. 5. A bevel gear mechanism having one or more gear mechanism stages, comprising: a gear mechanism housing that surrounds the gear mechanism stages; a motor cage, wherein said motor cage is adapted to be connected to an electric motor; a spacer flange, wherein said motor cage is connected to said gear mechanism housing via said spacer flange; a flanged bushing, wherein a drive side shaft of a bevel gear mechanism stage is supported in said flanged bushing, further wherein said spacer flange and a drive side end wall of said gear mechanism housing are provided with a common bore that extends around said flanged bushing, and wherein said flanged bushing has a cylindrical outer surface that is adapted to center said gear mechanism housing, said spacer flange and said flanged bushing; screws that interconnect said flanged bushing, said spacer flange and said drive side end wall of said gear mechanism housing; and a fan disposed within said motor cage on said drive side shaft of said gear mechanism, wherein openings are provided in an outer wall of said motor cage for a drawing-in of air, and wherein air openings are provided in said spacer flange for a discharge of the air. 6. A bevel gear mechanism according to claim 5, wherein said fan is a radial fan. 7. A bevel gear mechanism according to claim 5, which further comprises an air-conducting hood having an axial opening, wherein said air-conducting hood extends around said fan and is secured to said spacer flange. 8. A bevel gear mechanism according to claim 5, wherein on one side of said spacer flange ribs of said spacer flange and of a bearing plate of said spacer flange are disposed in a region of said air openings in said spacer flange, and on the other side of said spacer flange fins are disposed on said gear mechanism housing, further wherein said ribs and said fins are aligned with one another, and wherein said ribs and said fins form a flow path for the air that is drawn in by said fan from said motor cage. 9. A bevel gear mechanism according to claim 5, wherein said fan is provided with an annular surface that extends outwardly at an angle and that extends beyond said flanged bushing, and wherein apertures are disposed in said annular surface. 10. A bevel gear mechanism according to claim 5, wherein an end of said flanged bushing is provided with a flange that rests against said spacer flange on a side remote from said gear mechanism housing. 11. A bevel gear mechanism according to claim 5, wherein an outer wall of said motor cage, and said spacer flange, are provided laterally with flattened portions.
