Abstract: A device may be used to assemble a rotor segment of an electric machine. The rotor segment may include a rotor shaft, a laminated core joined to the rotor shaft, and two pressure elements that clamp the laminated core. A method for assembling the rotor segment may involve positioning the rotor shaft in the device and orienting the rotor shaft using an orienting means of the assembly device, positioning the laminated core and at least one of the first or second pressure elements within a clamping means of the device, orienting the laminated core by means of a positioning module of the clamping means, and moving the rotor shaft relative to the clamping means such that the laminated core is pushed onto the rotor shaft and the at least one of the first or second pressure elements is connected to the rotor shaft.

Abstract: A method for producing a ready-for-use camshaft for controlling valves of an internal combustion engine may be directed towards camshafts that include a carrier shaft on which an end component, for example, a drive wheel, a phase adjuster, or a part of a phase adjuster, is arranged and cam elements that are attached in a positionally fixed manner to the carrier shaft. In some examples, the method comprises providing a carrier shaft and an end component, joining the end component to the carrier shaft, grinding at least the carrier shaft to form cam seats so as to establish readiness for use, introducing a surface profile into a first cam seat, providing a cam element with ready-for-use characteristics, seating the cam element on the cam seat with the surface profile, and repeating certain steps for additional cam elements.
