摘要： A composite camshaft having a plurality of ferrous fitting members, such as cam lobes and journals, firmly bonded to a steel shaft by sintering in the presence of a liquid phase. The fitting members are fabricated as a green compact from metal powders and pre-sintered to axially shrink the compact by one-half a preselected allowance of shrinkage. Thereafter the pre-sintered fitting members are fitted on the shaft and sintered to axially shrink the compact by the remaining allowance of shrinkage and metallurgically join the shaft.

摘要： A composite camshaft is formed by brazing a journal to a shaft. After a brazing material is fitted into an annular groove formed on the center of the inner peripheral surface of a shaft-receiving bore in the journal, the journal is fitted onto the shaft and the brazing material is heated until it melts. The molten brazing material consequently completely fills a clearance between the inner peripheral of the shaft-receiving bore in the journal and the outer peripheral surface of the shaft, ensuring that the journal and the shaft are firmly connected.

摘要： A tool for supporting a composite camshaft having a steel shaft and a sintered piece to be joined to the steel shaft through sintering in a sintering furnace. The tool comprises a graphite frame having at least two sides, in an upper portion of which a groove means is formed. A ceramic layer is provided on a surface of the groove means. When sintering is performed using such a tool, the tool will not deform even if the tool is exposed to an environment of high temperature, such as the temperature higher than 1,100.degree. C., and therefore, bending of the composite camshaft will not occur during sintering. In addition, the ceramic layer prevents diffusion of carbon from the graphite frame to the steel shaft of the composite camshaft, and therefore, a hardening of the steel shaft due to carbonizing will not occur. As a result, reliability of the joint between the sintered piece and the steel shaft is increased.
摘要翻译：一种用于支撑具有钢轴和烧结片的复合凸轮轴的工具，其通过在烧结炉中烧结而与钢轴接合。该工具包括具有至少两个侧面的石墨框架，其上部形成有槽装置。陶瓷层设置在槽装置的表面上。当使用这种工具进行烧结时，即使工具暴露于诸如高于1100℃的高温环境的环境中，工具也不会变形，因此，复合凸轮轴的弯曲将不会在烧结。此外，陶瓷层防止碳从石墨框架扩散到复合凸轮轴的钢轴，因此不会发生由于碳化引起的钢轴的硬化。结果，烧结片与钢轴之间的接合部的可靠性提高。

摘要： A hollow cam shaft is composed of a hollow shaft having an inner hollow portion and an end piece which is pressure-welded to at least one end of the hollow shaft. The end piece comprises an end member which is pressure-welded to the one end of the hollow shaft and an enclosure member extending from the end member in an axial direction thereof so as to be inserted into the inner hollow portion of the hollow shaft at a time of pressure welding to define an enclosure space in the inner hollow portion of the hollow shaft. The enclosure member comprises a sealing portion having an outer shape substantially the same as an inner shape of the hollow shaft and a connection portion connecting an end surface of the end member of the end piece and the sealing portion so as to define said enclosure space between the enclosure member and the hollow shaft into which a burr generated at the pressure welding time is enclosed.
