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.

Abstract: An adapter system to connect a main shaft (9) of an electric motor to a device to be driven, in particular to a pinion of a gearing, is disclosed. The system comprises an adapter shaft (10) with a pinion attachment (11) on a first end, for rotationally stable connection to the pinion. A housing (20) is provided with devices (21, 22) to serve as bearings for the adapter shaft (10) and with a first flange (23) for attaching the housing to the gearing and with a second flange (24) for attaching it to the motor, such that the motor is substantially firmly connected to the gearing by way of the housing (20). A coupling element (40) can be connected to the motor shaft (9) in a rotationally stable manner.
