  • Patent number: 8732948
    Abstract: A resinous blade-supporting rotator is prepared to rotate around a rotational axis. The blade-supporting rotator has rotator weld parts including rotator weld surfaces formed on one side surface in the axial direction. A plurality of resinous blades are disposed annularly around the axis. The plurality of resinous blades have hollow spaces formed in the blade interiors, and blade weld parts with blade weld surfaces. The blade weld surfaces and the rotator weld surfaces are inclined with respect to each other when facing each other in the axial direction. An axial pressure load is applied to opposite axial ends of the blade-supporting rotator so as to compress the blades in the axial direction such that the blade weld surfaces and the rotator weld surfaces are no longer inclined with respect to each other. The blade weld surfaces are fixed to the rotator weld surfaces by laser welding.

  • Patent number: 8092181
    Abstract: A resin cross flow fan and a method for manufacturing a resin cross flow fan are provided in which an annealing step can be omitted and the number of circular disks can be reduced, and which provides improved fan strength and air blowing performance. A resin cross flow fan is disposed with a plurality of blades and a plurality of plates. The plurality of blades are annually disposed about a rotation axis. Insertion portions each constituted by a hole or a groove into which each blade is inserted and projecting portions that projects from the periphery of the insertion portions in a direction of the rotation axis are formed on each of the plurality of plates disposed spaced apart in the direction of the rotation axis. Each blade is fixed to the projecting portions by laser welding.

  • Patent number: 8007240
    Abstract: An impeller of a centrifugal fan includes an end plate, a plurality of blades and an end ring. The blades include blade bodies that are annularly disposed around a shaft and fixed to the end plate. The blades further include blade covers that are attached to the blade bodies. The blade covers and the blade bodies form a hollow space. The end ring is disposed such that it sandwiches the plural blades between itself and the end plate in a shaft direction. The blade covers form at least part of negative-pressure surfaces.

  • Publication number: 20100170634
    Abstract: A transmissive resin member and an absorptive resin member having lower optical transmittance than the transmissive resin member are superimposed together to form a superimposed part. Laser irradiation is performed from the side of the transmissive resin member while moving the irradiation position with respect to the superimposed part, and a noncombustible gas is blown onto the irradiation position from the side of the transmissive resin member in accordance with the movement of the laser light irradiation position. This laser welding method is particularly suited for manufacturing a resinous impeller for an air blower. A laser welding apparatus for the laser welding method includes a laser irradiation lens unit configured to irradiate resin members with laser light while an irradiation position is moved, and a discharge nozzle mounted on the laser irradiation lens unit and configured to blow a noncombustible gas toward the moving irradiation position.
