  • Publication number: 20230235816
    Abstract: A drive includes a housing, an adapter plate, and a cover hood. A flat support surface is provided on the housing, e.g., for placement of the cover hood, and the adapter plate is attached to the housing. A first sealing ring, e.g., an O-ring, is received on the outer circumference of the adapter plate and is arranged between the cover hood and the cover plate, e.g., for sealing. A second sealing ring, e.g., an O-ring or a flat sealing ring, is received and/or attached to the side of the adapter plate facing the support surface, and the second sealing ring is arranged between the adapter plate and the support surface, e.g., for sealing.

  • Publication number: 20220077740
    Abstract: 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.

  • Publication number: 20190379254
    Abstract: In a drive that includes an electric motor and a transmission, and a method for producing a drive, the housing of the transmission includes a housing part and a cover part, which are connected to each other. A bayonet guide region is arranged on the housing part. The electric motor includes a rotor shaft and a motor housing, and the rotor shaft is rotatably mounted in the motor housing with the aid of bearing(s). An adapter flange is connected to the motor housing in a torsion-resistant manner, the adapter flange including a lug region, in particular a bayonet nose, in particular for an engagement behind the bayonet guide region, the bayonet guide region projecting into a recess of the housing part. The recess is restricted in the circumferential direction by a holding fin provided on the housing part, which extends from a bearing receptacle of the bearing of the input shaft of the transmission, in particular in relation to the axial direction of the input shaft, in the radial direction, the recess, e.g.

  • Patent number: 9157507
    Abstract: A spare part set for a gearmotor series includes transmissions actuated by electric motors. The series has at least one dimension which may be characterized by at least one physical, mechanical and/or geometrical value, e.g., by nominal power, axis height or torque. Each electric motor includes at least one crankcase, a rotor provided with a rotor axis and a side-shield for a motor bearing arranged within a given size. The crankcase includes an interface with the side-shield for a motor bearing, which is selected such that at least two different embodiments thereof are connectable to the said crankcase.

  • Patent number: 7744473
    Abstract: An adapter device and a production series of adapter devices for connecting an input shaft, e.g., a motor shaft of a motor, e.g., an electric motor, to a device to be driven, e.g., to a pinion of a gear unit, including an adapter shaft for the rotatably-fixed connection to the device to be driven, an intermediate piece engaged with the adapter shaft, and a sub-component that is engaged with the intermediate piece and is detachably connectible with form-locking to an input shaft, particularly a motor shaft. The sub-component includes a bore hole for accommodating the input shaft in the sub-component, and the sub-component has at least three claws for forming the coupling. The adapter shaft, at its second end, thus at the end facing the intermediate piece, has at least three claws for forming a coupling. The intermediate piece is provided between the claws of the sub-component and the claws of the adapter shaft.
