Abstract
The engagement parts of the external rotor of a single-rotation machine having an internal axis with sealing between its rotors and with respect to the machine casing by sealing gaps, are manufactured as single parts and following reciprocal alignment are joined at their two ends to in each case one circular side part. Alignment takes place by engaging the cross-sectionally arcuate outer faces of the engagement parts on arcuate parts of an assembly cage and by dimensionally accurate assembly bodies engaging between the engagement parts. The method permits narrower sealing gaps for the machine and consequently an improved efficiency.
