    Abstract: A blade structure for a torque converter, produced by a process including the steps of: stamping a flat blank into a first annular plate that includes a first connecting ring portion, a second connecting ring portion, and a plurality of blades spaced from each other in a circumferential direction of the first and second connecting ring portions; bending the blades into a curved shape curved with respect to the first annular plate; bending the blades to be inclined by a predetermined angle with respect to the first and second connecting ring portions; and expanding the first annular plate outwardly in a radial direction thereof to thereby form a predetermined annular shape that has a larger radial dimension than the first annular shape and a larger circumferential distance between respective adjacent two of the blades than that in the first annular plate.

    Abstract: A centrifugal fan rotor includes radial blades extending from a disc support connectable to a hub for connection to the rotor's shaft. The blades are produced by stamping metal sheet, each having a corresponding blade surface and opposite attachment projection to the disc support. The rotor includes at least a first group of the blades in which each blade of the first group is provided with respective attachment projections upstream of the corresponding blade surface with respect to a direction of rotation of the rotor, and at least a second separate group of the plurality of blades in which each blade is provided with respective attachment projections arranged downstream of the corresponding blade surface with respect to rotation direction, such that each blade of the first and second groups are mirror-symmetrical to each other with respect to a radial center plane of symmetry between the blades extending through rotation axis.

    Abstract: A method for forming an inclined-blade blower wheel is provided by arranging a plurality of blades about respective circumferences of first and second end caps. The plurality of blades extend longitudinally between the first and second end caps and parallel to an axis defined by respective centers of the first and second end caps. The first end cap is rotated with respect to the second end cap a predetermined amount, therein skewing the plurality of blades at a desired longitudinal pitch between the first end cap and second end cap. The first end cap and second end cap are then rotated in unison while crimping the circumferences of the first end cap and second end cap, therein securing the plurality of blades to the first and second end caps and fixing the desired longitudinal pitch of the plurality of blades from the first end cap to the second end cap.

    Abstract: In a bladed rotor of the kind in which each blade has curved side surfaces and having fingers fitted in depressions of a shell and an opening of a core, the depressions of the shell and the opening of the core for receiving therein corresponding fingers of the blades are shaped and arranged so as to have, with respect to an elevational view of the rotor, longitudinal axes which coincide with straight lines extending radially through the center of the rotor, respectively. A die assembly for forming such depressions or openings in the shell or core is also provided. In such a die assembly, first and second die sections are adjustable in relative circumferential position for thereby adjusting the relative circumferential position relationship between the first and second groups of depressions or openings in the shell or core to be produced.
