摘要： [PROBLEMS] To provide a process for producing a lightweight race ring through steady unification, without any deformation, of an aluminum alloy member for constituting a main body of race ring and an iron base alloy member for constituting a raceway surface thereof. [MEANS FOR SOLVING PROBLEMS] Outer ring (41) of cross roller bearing is a composite part comprised of outer ring main body member (411) of aluminum alloy and, bonded to the inside thereof, outer ring side raceway surface constituting member (412) of iron base alloy. Layer of A7075 type alloy powder (413) is interposed between diffusion bonding face (411a) of outer ring main body member (411) and diffusion bonding face (412a) of outer ring side raceway surface constituting member (412) (step ST3), and diffusion bonding of the members (411, 412) is carried out (step ST4). It has been ascertained that the members (411, 412) can be strongly bonded and unified together by interposing the layer of alloy powder (413) even at bonding temperature lower than in the prior art. Thus, the diffusion bonding can be accomplished without any deformation of the outer ring main body member (411) of aluminum alloy.
摘要翻译：本发明提供一种用于构成用于构成座圈主体的铝合金构件和用于构成其轨道面的铁基合金构件的通过稳定地统一而不变形地制造轻型座圈的方法。交叉滚子轴承的外圈（41）是由铝合金的外圈主体部件（411）构成并与其内侧接合有外圈侧滚道面构成部件（412）的复合部件，的铁基合金。 A7075型合金粉末（413）的层叠在外圈主体部件（411）的扩散接合面（411a）和外圈侧滚道面构成部件（412）的扩散接合面（412a）之间（步骤ST 3），并且进行构件（411,412）的扩散接合（步骤ST4）。已经确定，即使在比现有技术中低的接合温度下，也可以通过插入合金粉末（413）来将构件（411,412）牢固地结合在一起。因此，可以在铝合金的外圈主体部件（411）的任何变形的情况下实现扩散接合。
