摘要： A process for the production of cup tappets for reciprocating-piston machines having a pressure plate made from wear-resistant alloyed tool steel and a cup casing, welded to the pressure plate, and made from cheap and cold-extrudable steel utilizes a friction welding process to weld the two parts to one another in a crack-free manner. The cup casing blank is produced by the cold-extrusion process and is carbonized before the welding so that good welding results can thereby be achieved despite the considerable strength differences and cross-sectional differences between the pressure plate and cup casing blanks. As a result of a preheating of the pressure plate, an impairment of the cup casing blank during the frictional heating can be compensated and cracks in the workpiece during or immediately after the welding can thereby be avoided. The pressure plate blank can be designed as a flat round which can be produced by stamping and which projects radially to a pronounced extent relative to the cup casing blank, so that it can be tensioned in an overhand region during the friction welding. The outer overhang containing possible cracks is removed in a subsequent chip-removing, preferably grinding operation.
摘要翻译：用于生产具有由耐磨合金工具钢制成的压板和焊接到压力板上并由便宜且可冷挤出的钢制成的杯套的往复活塞机的杯形挺杆的方法使用摩擦焊接工艺以无裂纹的方式将两个部件彼此焊接。杯套坯是通过冷挤压工艺生产的，并且在焊接之前被碳化，从而可以实现良好的焊接结果，尽管压板和杯套坯之间存在相当大的强度差异和截面差异。作为压板的预热的结果，可以补偿摩擦加热期间的杯套坯料的损伤，从而可以避免焊接期间或之后的工件的裂纹。压板坯件可以设计成平圆，其可以通过冲压产生，并且相对于杯壳坯料径向伸出显着的程度，使得其可以在摩擦焊接期间在过度区域中被张紧。在随后的切屑除去，优选研磨操作中，可以除去包含可能的裂纹的外悬垂。

摘要： A welded crankshaft having a number of individual elements and cavities formed in the region of the main bearing journals and crank journals. The individual elements are configured so that oil passages in the overlap region between the main bearing journals and crank journals run substantially in the axial direction, and transition via radial orifices directly into the journal surface. The cavities of the main bearing journals and crank journals can be made very large, so that the weight of the crankshaft is kept light. In addition, because of the simple geometry of the oil passages, the crankshaft can be manufactured in modular fashion from the individual elements.

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.

摘要： A composite shaft/disc workpiece which is assembled from a disc with a passage hole and from a shaft by friction welding is disclosed. The outer wall of the shaft has a plurality of steps in the connection region with the disc, the radius of the steps becoming larger in a direction of the axis. The passage hole of the disc is provided with webs, the radius of which likewise becomes larger in a direction of the axis and between which annular recesses are present. The webs and steps to be connected overlap in the radial direction, so that, during the welding of the shaft and disc, annular connecting portions are obtained in the region of the webs and steps, annular cavities being formed between the connecting portions. The cavities represent a weight saving, as compared with composite shaft/disc workpices made of solid material, and can also be used as parts of media ducts.
