Publication number: 20230400089Abstract: A gear system includes a housing part. The housing part has a cylindrical inner wall which radially surrounds the wheel, e.g., toothed part, such as a gear, connected to the output shaft of the gear system for conjoint rotation. On the cylindrical inner wall are formed projections, which are spaced from each other in the circumferential direction, e.g., are spaced from each other at regular intervals, and which project radially inwards and extend axially. For example, the projections are longer in the axial direction than in the circumferential direction and in the radial direction.Type: ApplicationFiled: October 13, 2021Publication date: December 14, 2023Applicant: SEW-EURODRIVE GMBH & CO.

Publication number: 20220368194Abstract: A geared motor includes a gear unit, a first, a second, or a third electric motor, and an adapter part situated between the gear unit and the electric motor. On its side facing the electric motor, the adapter part has a first, a second, and a third centering device, and on the side facing away from the electric motor, it is connected to the gear unit. The centering devices are radially set apart from one another, and the second centering device is situated radially between the first and third centering devices. The electric motor has an axially protruding centering ring, which is centered by only a single one of the centering devices of the adapter part, and the other centering devices are radially set apart from the centering ring and/or have no centering function, e.g., for the centering ring.Type: ApplicationFiled: June 15, 2020Publication date: November 17, 2022Applicant: SEW-EURODRIVE GMBH & CO.

Publication number: 20220077740Abstract: A drive includes an electric motor, having a rotor shaft rotatably mounted in a motor housing by bearing(s), and a transmission, having a transmission housing including a housing part and a cover part connected together. A bayonet guide region is arranged on, and projects into a recess of, the housing part. An adapter flange is connected to the motor housing in a torsion-resistant manner and includes a lug region engageable behind the bayonet guide region. The recess is restricted in the circumferential direction by a holding fin provided on the housing part, extending from a bearing receptacle of the bearing of the input shaft of the transmission in the radial direction and is restricted counter to the circumferential direction by a further holding fin provided on the housing part, extending from a bearing receptacle of the bearing of the input shaft in the radial direction.Type: ApplicationFiled: November 15, 2021Publication date: March 10, 2022Inventors: Roland DENEFLEH, Oliver BÜHN, Henning UNTERBURG, Martin KERSCHBAUM
