Abstract: A clamp coupling has a slotted clamping ring seated on a first rotatable part. A clamping screw is arranged in the clamping ring and acts on the clamping ring to elastically spread the clamping ring apart and contract the clamping ring depending on the turning direction of the clamping screw. The first rotatable part has axially oriented slots that extend up to a free end face of the first rotatable part and that separate coupling segments of the first rotatable part from each other. The slots are arranged in an area surrounded by the clamping ring. The coupling segments receive a second rotating part and are clamped by the clamping ring on the second rotating part. A follower part is arranged on the clamping ring and in a spreading-apart direction of the clamping ring is fixedly connected with at least one of the coupling segments.

Abstract: A drive device has a gear unit having a gear shaft and a motor unit having a motor shaft drivingly connected to the gear shaft. At least one cooling unit is arranged within the drive device for dissipating thermal losses. The cooling unit can be arranged in the gear unit or between the gear unit and the motor unit. For example, the cooling unit has at least one fan that can be arranged in a coupling unit between the gear unit and the motor unit. Instead of or in addition to the fan, a cooling liquid flowing through a flow chamber can be used.
Abstract: A casing has casing parts and fastening elements, wherein the casing parts are connected to one another by the fastening elements. The fastening elements are located inside the casing so that the exterior of the casing is free of projections and recesses. A first one of the casing parts has through openings into which the fastening elements are inserted, and a second one of the casing parts has threaded bores for receiving the fastening elements.
Abstract: A switching device for controlling at least two motors has a single converter, wherein the at least two motors are connected to the converter by a power line and a feedback line, respectively. At least one logic module is connected to the converter and evaluates signals received from the converter to generate a control signal for controlling the motors. The converter has an interface for selecting one of the motors to be controlled, wherein the interface is connected by a signal line to the at least one logic module. The power lines and the feedback lines each have a switch. The at least one logic module is adapted to switch with the control signal at least two of the switches for switching the respective power line and the respective feedback line of the motor to be controlled.
