  • Patent number: 8881392
    Abstract: A method of using machining to repair a component workpiece, such as a turbomachine blade, from a known profile of the component, is disclosed. The method includes deforming the profile using a morphing method so that the deformed profile interpolates a cluster of points measured on the component. Deforming the profile involves comparing each zone of the component workpiece that has excess or insufficient thickness with elementary deformation configurations (EDCs) each in the form of a mesh portion and of points, the elementary deformation configurations (EDCs) being filed in a database, the database associating the parameters of the morphing function with each elementary deformation configuration (EDC).

  • Patent number: 8881393
    Abstract: In a manufacturing method of an impeller for a fluid transmitting device, multiple guide grooves aligned in a peripheral direction to allow communication between adjacent ones of multiple positioning holes are provided in a concave inner surface of a core in advance; and in a step of melting a brazing material and causing the molten brazing material to penetrate into gaps between coupling pieces and positioning holes that are fitted to each other and further into gaps between the core and the blades, the molten brazing material is guided to the positioning holes through the multiple guide grooves. Accordingly, the step allows the molten brazing material to be efficiently guided to the gaps between the coupling pieces and positioning holes, thereby improving the yield of the brazing material and preventing an influence of a residual brazing material over the rotational balance of the impeller.

    Abstract: A torque converter having a housing with an impeller wall section, and pump vanes brazed to the impeller wall section. The housing is connected to an output of an engine for rotation about a longitudinal axis. A turbine having turbine vanes that are connected to a hub is located about the longitudinal axis within the housing and is connected to an input shaft of a transmission. A stator is located between the pump vanes and the turbine vanes. In order to allow for a thinner housing wall, particularly an area of the impeller wall section, an annular retainer plate is brazed to the impeller wall section about the longitudinal axis and forms a reinforcement. A rolling bearing is located between the retainer plate and the stator, and is used in supporting the housing. An assembly method is also provided.
