Problems solved by technology
However, based on this desired radial play between the outer diameter of the shaft section and the inner diameter of the laminated core, a degree of freedom of contact occurs between these parts, which has the disadvantage that it is not possible to use connections known from the general prior art Techniques such as lateral interference fit or form fit (this is the usual way of centering and angular orientation of laminated cores)
However, with the method described here, it is not possible to achieve the desired radial play between the outer diameter of the shaft and the inner diameter of the laminated core

Embodiment Construction
[0053] exist Figure 1 to Figure 16 , elements with the same function and mode of operation have the same reference numerals.
[0054] figure 1 The rotor shaft 1 is shown in a side view, in particular the method of pre-assembly of the rotor shaft 1 . The rotor shaft 1 has a shaft section 2 with a first material reinforcement 3 or roll-polished 3 at a first distal end 2.1 and a second material reinforcement 4 or roll at a second distal end 2.2 Press polishing part 4 . Advantageously, the shaft segment 2 itself is formed as a solid shaft or as a hollow shaft. During pre-assembly, in order to manufacture the rotor shaft 1, the shaft segment 2 is connected to the first flange element 5 (which is arranged at the first end face 2.3 of the shaft segment 2). After arranging the first flange element 5 on the shaft segment 2, the first pressure element 7, formed for example as a pressure plate, is advantageously pushed onto the shaft segment 2 in the assembly direction M. Advantage...

The invention relates to a method and to an assembly device for assembling a rotor segment of an electric machine, wherein the rotor segment at least has a rotor shaft, at least one laminated core joined to the rotor shaft, and two pressure elements, which clamp the at least one laminated core, and wherein the method at least has the following steps: arranging the rotor shaft in an assembly deviceand orienting the rotor shaft using an orienting means of the assembly device; arranging the at least one laminated core and at least the second pressure element or the first pressure element withina clamping means of the assembly device; orienting at least the at least one laminated core by means of a positioning module of the clamping means; and moving the rotor shaft in relation to the clamping means in such a way that the at least one laminated core is pushed onto the rotor shaft and at least the second pressure element or the first pressure element is connected to the rotor shaft. The invention further relates to a rotor segment, having a shaft segment and at least two laminated cores, which can be arranged at an offset to each other in respect of angular position, wherein each of the laminated cores has at least one marking.
Description
technical field [0001] The present invention relates to a method and an assembly device for assembling electric machines. Background technique [0002] The use of electrical machines, such as electric motors or generators, is basically known. Electric machines are machines used in electrical engineering and constitute a form of energy converter. There are many different types of motors, so that they are distinguished from each other in particular by their layout. For example, in rotating electrical machines, a distinction can be made between commutating machines, synchronous machines, and induction machines. This classification relates specifically to the operating mode of the machine itself. Rotating electrical machines can also be classified in terms of the type of their current flow, so that, for example, a DC motor, an AC motor or a three-phase AC motor can be involved. A motor basically has a stator (ie, a stationary element) and a rotor (representing a rotating ele...
