  • Publication number: 20230407957
    Abstract: A transmission includes a first housing part, a second housing part connected to the first housing part, and bearings accommodated in the first housing part and supporting an input shaft in a rotatable manner. The input shaft projects through a recess that extends through the second housing part, and a cover part is connected to the first housing part. The cover part or a flange part inserted into the cover part accommodates a sealing system, which provides sealing with respect to the input shaft. The second housing part has an inlet for lubricating oil, which terminates in an axial bore being open with respect to the side of the first housing part facing the cover part, and in a second annular space. The opening of the axial bore facing the cover part is covered and/or sealed by the cover part, and rolling elements of two bearings at least also restricting and/or surrounding the second annular space together with the first housing part.

  • Patent number: 11767906
    Abstract: A transmission includes a housing, having lower and upper housing parts and bearing seats. A web is formed on the lower housing part between two bearing seats, which is pressed against a web provided on the upper housing part and between the bearing seats. When the housing parts are separated or pulled apart, a first web of one of the housing parts projects beyond a planar surface, which restricts the other webs thereof, or the webs of one of the housing parts are restricted by a planar separating surface, and except for a first web, the webs of the other housing part are also restricted by the planar separating surface and the first web projects beyond the separating surface when the housing parts are separated from each other. To form the housing, at least one of the housing parts is elastically deformed and/or preloaded.

  • Patent number: 10718421
    Abstract: A gearing having a shaft that projects from the gear interior into the environment, the shaft being sealed with the aid of at least one contactless seal, and the opening of the contactless seal, which is oriented toward the interior of the gearing, i.e., the spatial region of the gearing that contains the lubricating oil, being disposed above the lubricating oil level that comes about when the gearing is not in operation, a tin piece being disposed between the opening and the gear-tooth piece situated closest to this opening and generating lubricating oil waves and/or lubricating oil foam from the lubricating oil bath.

  • Patent number: 10539223
    Abstract: A gear unit includes a shaft, in particular an input shaft, a flange part and a housing part. The input shaft is supported by bearings in the housing part, and a fan is connected to the shaft in a torsion-proof manner. The housing part includes cooling fins, in particular cooling fins that extend in the axial direction, i.e. in the axis direction of the shaft, the cooling fins have an offset and/or stepped configuration, and the flange part surrounds the offset or stepped region of the cooling fins, in particular in the manner of a housing.

  • Patent number: 9062718
    Abstract: In a connection of a shaft to a mounting part, in particular a shaft-hub connection, the shaft has a first axial region which is able to be accommodated in the mounting part, the shaft has an additional axial region which has a larger diameter than in the first axial region, a transition region is provided between the first and additional axial region, whose diameter increases in the axial direction from the first to the additional axial region, from the value of the diameter of the first axial region to the value of the diameter of the additional axial region, in particular not exclusively abruptly, a bushing is provided between the shaft and the mounting part, the bushing having an axial region, in particular an axial terminal region, which is elastically deflectable by the transition region such that it is pressed against the wall of the mounting part, in particular when the shaft is inserted into the mounting part.
