A device for improving the method of manufacturing Archimedes screws by 5 assembling sectors. The invention relates to a device for producing an Archimedes screw by assembling sectors on a shaft (13) without forming gaps, cutting edges or weak regions between one another and ensuring the continuity of the tums of which said screw consists. It consists of a sector (3) having a turn with a length equal to one screw thread and having a geometry that enables it to be interlocked with 10 another, identical sector (3). The turn sits on a core, the geometry of which is obtained by following in each case a helical generatrix which is offset through at least one turn thickness. The terminal face of the turn is inclined a tone turn thickness. The terminal face of the turn is inclinded at an angle with respect to the axis of the sector. The device according to the invention is particularly intended for 15 the production of systems for metering or pumping viscous, pulverulent or granular products, said systems comprising at least one Archimedes screw. |
