  • Publication number: 20140099209
    Abstract: A method is provided for casting a gas turbine component having at least a first section and a second section. As per the method, a liquid metal is cast into a casting mold and solidification of the metal is induced by means of controlled cooling. The cooling of the liquid metal in the first section is controlled in such a way that the metal solidifies in a directionally solidified crystal structure or a single-crystal structure. In the second section the cooling is carried out in such a way that it solidifies in a multidirectional crystal structure.

    Abstract: A rack bar includes a shaft portion and a rack toothed portion provided on the shaft portion. The rack toothed portion includes a plurality of rack teeth provided side by side in an axial direction of the shaft portion to mesh with a pinion gear. Each of the rack teeth includes a tooth tip portion, a contact face arranged obliquely relative to the axial direction and configured to contact the pinion gear, and a rounded corner portion between the tooth tip portion and the contact face. A first radius defining a central area of the rounded corner portion with respect to a tooth width direction is larger than a second radius defining another area of the rounded corner portion other than the central area.

  • Publication number: 20140083642
    Abstract: An apparatus and method for pressure casting a battery part wherein an extendible piston includes sidewalls for shutting off the supply of molten lead and an impact surface that extends in a side-to-side condition to form an end surface of a battery part cavity so that when the extendible piston is brought into an intensifying condition the extendible piston shuts off further supply of molten metal while a heat source maintains the lead in a molten state as the impact surface of the piston forms a side-to-side mold cavity surface to complete the mold cavity surface thereby eliminating unevenness in the surface of the finished battery part by generating a force with the extendible piston which is sufficient to form a battery part so that upon removal from the mold the batter part is substantially free of tears and cracks as well as surface irregularities.

  • Publication number: 20140072447
    Abstract: A core assembly for forming a cast component includes a refractory metal core and a ceramic core element. The refractory metal core includes first and second ends and sides extending from the first end to the second end. The ceramic core element includes a slot positioned between first and second lands, each land having an inner surface facing the slot and an adjacent outer surface. The first end of the refractory metal core is secured within the slot with an adhesive, and the refractory metal core extends from the ceramic core element in both a longitudinal and a transverse direction. The slot, lands, and refractory metal core form a core assembly providing access paths to the sides of the refractory metal core. Surplus adhesive is removed from the refractory metal core via the access paths. Investment casting provides the component with an internal passage and an internal cooling circuit.
