Abstract
Die Erfindung betrifft eine Gebläseanordnung, bestehend aus einem von einem Motor angetriebenen Zentrifugalgebläserad (3), dem ein Leitrad (7) zugeordnet ist, das das Zentrifugalgebläserad (3) umfangsmäßig umgibt und mit dem Zentrifugalgebläserad (3) zusammen in einem gemeinsamen, an das Gehäuse (10) des Motors anfügbaren Gebläsegehäuse (13) eingebaut ist, bei welchem Zentrifugalgebläserad (3) an einer mit der Welle des Motors drehfest gekuppelten Tragscheibe (4) axial vorstehende Förderschaufeln (5) angeordnet sind, auf deren der Tragscheibe (4) abgewandten Seite eine Deckscheibe (6) aufgesetzt ist, bei welcher Gebläseanordnung ferner das Gebläsegehäuse (13) im Bereich der Einlaßöffnung (17) die radial innere Umfangskante (20) der Deckscheibe (6) unter Belassung eines Spaltes (21) überlappt. Eine weitere Verminderung der Rückströmverluste ist dadurch möglich, daß in dem Überlappungsbereich des Gebläsegehäuses (13) mit der Deckscheibe (6) an dem Gebläsegehäuse (13) eine an diesem festhaftende elastische Dichtungsmasse (23) aufgebracht ist, die beim Anfügen des Gebläsegehäuses (13) an das Motorgehäuse (10) unter Vermeidung eines Festhaftens an der Deckscheibe (6) den Spalt (21) ausfüllt. The invention relates to a blower arrangement consisting of a centrifugal blower wheel (3) driven by a motor, to which a stator (7) is associated, which surrounds the centrifugal blower wheel (3) circumferentially and together with the centrifugal blower wheel (3) in a common to the housing (10) of the motor-attached blower housing (13) is installed, in which centrifugal fan wheel (3) are arranged on a support disk (4) which is rotatably coupled to the shaft of the motor, axially projecting conveyor blades (5) on the side facing away from the support disk (4) a cover plate (6) is placed, in which fan arrangement the fan housing (13) in the area of the inlet opening (17) overlaps the radially inner peripheral edge (20) of the cover plate (6) while leaving a gap (21). A further reduction in the backflow losses is possible in that in the overlap area of the blower housing (13) with the cover plate (6) on the blower housing (13) an elastic sealing compound (23) is adhered to the blower housing (13), which is attached when the blower housing (13) is attached. fills the gap (21) on the motor housing (10) while avoiding sticking to the cover plate (6).
