摘要： In one aspect, a fan assembly is provided that can be manufactured while producing a significantly reduced amount of scrap material. More specifically, the fan assembly utilizes a hub ring and one or more hub strips to support a plurality of blades rather than a solid center disc or end disc used by some prior approaches. In another aspect, a method is provided that includes bending a member into an annular configuration and joining end portions of the member together to rigidly fix the member in the annular configuration. The rigid annular member may be used as an end ring, a hub ring, an orifice, or other component, while producing significantly less scrap material than traditional approaches.

摘要： The present invention provides an impeller in which a metallic bush can be inserted correctly into a synthetic resin impeller main body manufactured by resin molding using a die, and a determination as to whether or not the impeller has been manufactured correctly can be made easily. The impeller comprises: a metallic bush comprising a circumferential boss portion having a substantially truncated cone-shaped throttle portion positioned on a front surface axial end side, a periaxial support boss portion positioned in an axial center, and a circumferential protruding portion positioned on a back surface axial end side; and an impeller main body made of synthetic resin and formed with a V-shaped bulging portion that bulges axially in the center of a front surface side of a disk-shaped vane portion fulcrum, in which a plurality of vanes are formed integrally on the periphery of the V-shaped bulging portion. An outer diameter of the circumferential protruding portion of the bush is formed to be smaller than an outer diameter of an axial end location of the throttle portion, the circumferential protruding portion is positioned on a back surface side of the V-shaped bulging portion, and the bush is inserted into the V-shaped bulging portion.

摘要： Es wird ein Verfahren zum Herstellen eines Laufrads eines Ventilators, das Stützscheiben und jeweils ein gekrümmtes Querschnittsprofil besitzende Lamellen aufweist, vorgeschlagen. Das Verfahren zeichnet sich dadurch aus, daß zunächst die Lamellen axial in Aufnahmeöffnungen der Stützscheiben eingeschoben werden. Anschließend wird die Profilhöhe jeder Lamelle dadurch vergrößert, daß diese im Bereich der Aufnahmeöffnung plastisch verformt wird, derart, daß sich die Lamelle in ihrer Aufnahmeöffnung verklemmt.

摘要： A centrifugal compressor wheel for example for a turbo charger consists of a cast blade shell (12) formed with a hub (15) and integral blades (14) and a back plate (20) in which is formed a conical recess (30). A hub insert (16) which is forged or machined or otherwise non-cast to be more resistant to fatigue failure than the blade shell, is secured in the recess, preferably by inertia welding, to form an intimate bond over substantially the whole surface of the recess in a position such that the greatest stresses to be experienced in use will occur in the hub insert rather than the blade shell. A bore (46) is formed in the blade shell and hub insert for mounting on a blower shaft.

摘要： Systems and methods for attaching one or more impellers to a shaft and attaching composite rings to a back and front lip on each impeller to secure the impellers for high angular velocity operation. The composite rings are constructed of a material that provides a greater specific strength and greater specific stiffness relative to the material of the impellers. In multi-impeller assemblies, an impeller spacer is attached between each pair of impellers.
