Abstract
A transmission housing includes a plurality of side walls, at least one of the side walls including one or more housing openings for accommodating a bearing. A rib structure is formed on an inner side of one of the side walls and designed to taper in a funnel shape vertically above one of the housing openings in a direction of the one of the housing openings. A collecting pan is formed by a drill hole traversing the one of the side walls, with the rib structure opening into the collecting pan.
Claims18
A transmission housing, comprising:
- a plurality of side walls, at least one of the side walls including one or more housing openings for accommodating a bearing;
- and
- a rib structure formed by at least two ribs which taper vertically downward toward each other on an inner side of one of the side walls vertically above one of the housing openings toward the one of the housing openings and terminating in a collecting pan formed by a drill hole extending through the one of the side walls, with the drill hole forming the collecting pan in cooperation with a portion located on the inner side of the one of the side walls.
An industrial application, comprising:
- a transmission coupled in a torque-transmitting fashion to a mechanical application and including a transmission housing which comprises a plurality of side walls, with at least one of the side walls including one or more housing openings for accommodating a bearing, a rib structure formed by at least two ribs which taper vertically downward toward each other on an inner side of one of the side walls vertically above one of the housing openings toward the one of the housing openings, and terminating in a collecting pan formed by a drill hole extending through the one of the side walls, with the drill hole forming the collecting pan in cooperation with a portion located on the inner side of the one of the side walls.
A method for producing a transmission housing, the method comprising:
- casting a rib structure with no undercuts on an inner side of a side wall as viewed from a direction perpendicular to the side wall such that the rib structure tapers vertically above a housing opening of the side wall in a direction of the housing opening;
- and
- drilling a drill hole in the side wall in a vertically lower region of the rib structure to form a collecting pan.
