Abstract
In a method for producing a cellular wheel made of metal, the following steps are conducted consecutively: (a) providing a sheet metal strip () having a length () that corresponds at least to the length of a circumferential line of an intermediate sleeve and a width (b) that corresponds at least to the length of the cellular wheel; (b) placing disks () in predetermined locations in predetermined quantities on both sides of the sheet metal strip () perpendicular to the sheet metal surface and perpendicular to the longitudinal direction of the sheet metal strip () and connecting the disks () to the sheet metal strip () by welding or brazing; (c) bending the metal strip () equipped on both sides with the disks () and connecting the two ends of the sheet metal strip () by welding or brazing to form the intermediate sleeve; (d) placing a first tubular sleeve that is concentric to the intermediate sleeve as an outer sleeve, and a second tubular sleeve that is concentric to the intermediate sleeve as an inner sleeve, and connecting the free ends of the disks () to the outer sleeve or the inner sleeve by welding or brazing. The method allows cellular wheels to be produced which have material wall thicknesses of 0.2 mm and less for use in pressure wave superchargers.
