Publication number: 20230407957Abstract: 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.Type: ApplicationFiled: September 1, 2023Publication date: December 21, 2023Applicant: SEW-EURODRIVE GMBH & CO.

Patent number: 11767906Abstract: 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.Type: GrantFiled: March 7, 2022Date of Patent: September 26, 2023Assignee: SEW-EURODRIVE GMBH & CO.

Publication number: 20220186824Abstract: 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.

Patent number: 10539223Abstract: 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.Type: GrantFiled: March 7, 2016Date of Patent: January 21, 2020Assignee: SEW-EURODRIVE GMBH & CO.
