Abstract: The invention relates to a method for precision-casting a metallic molded part or several metallic molded parts preferably of equal dimensions, in which method a metallic melt is poured into a ceramic casting mold, with the metallic melt being left to freeze thereafter. In order to achieve a void-free structure, in particular even with an intensified cooling of the melt during the freezing, it is suggested according to the invention to cool the poured melt in an intensified manner with a pressure being exerted on the melt, whereby exertion of pressure and intensified cooling are maintained at least until the dimensional stability of the freezing molded part or molded parts. The invention further relates to a device for precision-casting a metallic molded part or several metallic molded parts of equal dimensions.

Abstract: The invention relates to a connecting rod (1) for racing engines with an upper connecting rod top end (2) and a lower connecting rod top end (3) and a hollow shank (6) that extends from a bearing region (4) of the upper connecting rod top end (2) to a bearing region (5) of the lower connecting rod top end (3). In order to create a connecting rod of this type, which can be embodied in a lightweight manner with thin walls in the shank area and nevertheless withstands high stresses, it is proposed according to the invention that at least one strut (7) is provided which runs from the shank (6) to the bearing region (5) of the lower connecting rod top end (3).

Abstract: A part data entry system is provided. In that system, an order processing template is provided to facilitate sales and order processing, tool planning, CA (computer aided) (e.g., CAD/CAM) parametric modeling, computer simulation, and the generation of a factory machine program. The order processing template comprises financial and manufacturing engineering planning fields and technical fields. A part information population mechanism is provided to populate the order processing template with the part information. An order template population mechanism is provided to populate other ones of the financial and manufacturing planning fields and the technical fields that are not populated by the part information population mechanism. An order processing template interface, or a set of such interfaces, is provided to provide, for a given ordered part, from the order processing template, CA-specific information to a CA computer system before the CA computer system performs CAD modeling on the part.

Abstract: A system is provided for creating specialty machine control programs for manufacturing a part. A CA (computer aided) computer system is provided. The CA system may comprise a computer aided design and computer aided manufacture (CAD/CAM) computer system. The CA computer system may further comprise a computer aided engineering (CAE) computer system. The CA computer system may further comprise a computer aided quality (CAQ) computer system. The CA computer system comprises a parametric design mechanism to specify geometries of the part with parameters. In addition, an intelligent geometry portion is provided to determine machining cycles to manufacture the part. A 3D solid modeling function is provided, and one or more simulation components are provided. A human-readable control program generator is provided to generate from the CA computer system a human-readable control program including instructions for a human to carry out.

Abstract: A system is provided for part ordering, design, and manufacturing. A manufacturer computer system is provided which comprises a parametric design mechanism to specify geometries of the part with parameters, an intelligent geometry portion, a 3D solid modeling function, and one or more simulation components. The intelligent geometry portion determines machining cycles to manufacture the part. Part-related databases are provided, and order processing components are provided. Such part-related databases and order processing components may form part of one or both of an ERP and PLM computer system. An order processing template is provided to facilitate sales and order processing, tool planning, CA parametric modeling, computer simulation, and the generation of a factory machine program. The order processing template comprises financial and manufacturing engineering planning fields and technical fields. An order template interface, or a set of order template interfaces, is provided.

Abstract: The invention concerns the securing of the wheel carrier of a driven wheel of a motor vehicle, especially a racing or sports vehicle, on the chassis, wherein the force transfer of the drive runs from a chassis-side part of an inside universal joint (6), then through the shaft-side part of the universal joint, a drive shaft (7), a shaft-side part of an outside universal joint (5), and a wheel carrier-side part of this universal joint, to the wheel carrier (3).

Abstract: The invention concerns a method for the installation of pretensioned roller bearings (2), in particular angular ball bearings, for example, in wheel carriers of automobiles, airplanes, and the like. The invention is characterized in that the installation apparatus, with a measurement probe (5), lies against a stop, a shoulder, or the like, in the axial area of the bearing race of one roller bearing, on the shaft side, and that upon tightening the shaft nut (3) against the bearing race of the other roller bearing, on the shaft side, its axial shift with respect to the stop is determined, wherein when the shaft nut is tightened, a torque wrench is used to determine the applied torque, which permits it to differentiate between the actual tensioning process of the roller bearing (2) and the previous process to bring the shaft nut (3) to the stop. The invention also concerns an installation apparatus to implement the method.
