Method for the production of delivery and/or guiding devices for hydrodynamic machines and a radial rotor, especially a coolant pump impeller for internal combustion engines, produced by this method

摘要

In a method for the production of delivery and/or guiding devices for hydrodynamic machines, the delivery and/or guiding devices being produced with blades arranged on the outer circumference of a ring- or disc-shaped part by means of radial connecting webs, the blades are arranged relative to the blade carrier in a process which involves the permanent deformation of the connecting webs. To achieve a design of radial-flow delivery and/or guiding devices for hydrodynamic machines which is optimised in terms of efficiency and, at the same time, is of simple construction, the proposal is that the connecting webs should each be arranged on the blade carrier over as small as possible a cross-section and that the blades should be arranged in positions axially adjacent to the blade carrier to form a radial-flow delivery and/or guiding device, this being achieved by successively swivelling the connecting webs in different ways or three dimensionally by means of bending and twisting them at their smallest cross-sections. <IMAGE>
