Abstract: A transmission housing includes a profile body configured to enclose transmission components, two side walls configured to enclose the transmission components in the profile body, and a hub rail inserted into a recess of one of the two side walls and fastened to the one of the two side walls, The hub rail includes at least two hubs and is defined by a hub width which is higher than a wall thickness of each of the two side wails. The profile body, the two side walls and the hub rail are each configured without joints in a radial direction of the at least two hubs in order to prevent radial insertion of a one of the transmission components into the hubs.

Abstract: 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.
