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 joint-site structure for a shaft/disk composite workpiece, in particular for joining a shaft 1 to a connection flange 2 of a hub part of the disk by means of friction welding. A respective defined gap 4, 4′ is incorporated between shaft 1 and connection flange 2 of the hub part in front of and behind a joint site 3, this gap 4, 4′ preventing the spread of the material softened during the friction welding. The joint-site structure is used, for example, during the joining of a crankshaft and a hub part of a drive wheel.
