    摘要： Motors with high power densities and ignition pressures, for example diesel motors, require crankshafts with combined gear wheels, which can withstand high stresses, especially in their connection areas. As a consequence, forged steel crankshafts, to which tempered gear wheels are fixed by means of screws or welding, are usually employed. The aim of the invention is to provide a method comprising fewer method steps for producing a crankshaft with a combined gear wheel and to provide a crankshaft that has been produced according to said method. To achieve this, the crankshaft comprising the combined gear wheel is cast in one piece. Tempered ductile iron is used as the starting material. The strength and wear resistance is increased locally by peening, or by the application of coatings containing carbide.

    摘要： A lightweight crankshaft (1), with eccentric structures, such as con-rods, main bearings, etc., comprises cavities (2, 3, 4, 5, 7, 10, 12) and/or recesses (8) for weight reduction, both in the region of the axis of rotation and isolated therefrom in the region of the eccentric structures. According to the invention at least one cavity is provided (2, 3, 4, 6, 7, 10, 12) in which a stabilizing filler material (5) is located. Said stabilizing filler material can, for example, be a metal foam.

    摘要： A process for producing a fiber-reinforced, ceramic structural component comprising high-temperature resistant fibers which are reaction-bonded to a matrix of silicon carbide comprises the steps of coating bundles of fibers with pyrolysable binder and solidifying the binder, producing mixtures of fiber bundles, fillers and binders, pressing the mixtures to produce a pressed body, pyrolysing the pressed body under the exclusion of oxygen to form a porous, carbon-containing preform, infiltrating the preform with a silicon melt to form the silicon carbide matrix, in which various pressing compounds are produced, which contain fibers of different quality and in different proportions and different coatings. These pressing compounds are arranged at different levels and in different spatial directions in the press mould during the filling of the press mould. After the pressing, the regions produced in this way are retained in the press mould. After the infiltration of the preform with silicon, the structural component is distinguished by different materials properties, in particular ductility and resistance to wear.
