    • PROBLEM TO BE SOLVED: To provide a bearing device for a wheel that can set and maintain appropriate fitting pre-load in serration fitting of a hub wheel and a constant velocity universal joint, by which wear resistance and strength of a serration part is improved, and fitting effective length of the serration fitting is reduced.SOLUTION: The bearing device for the wheel includes: an outer member 25 including an outside rolling surface in the inner circumference; an inner member including an inside rolling face including an inner rolling surface facing the outer rolling face; and a rolling element 30 interposed between the mutually facing rolling surfaces. The inner member is constituted of the hub wheel 1 attached to a wheel, and at least one inner wheel 24 fitted to the notched part 23 of the hub wheel, and the end part of the hub wheel is caulked to fix the inner wheel. A female serration 42 is formed in the inner circumference of a hole part 22 of the hub wheel. A hardened layer is provided in the forming region of the female serration. The female serration is formed by machining with a cemented carbide broaching tool after the hardened layer H is formed and caulked.
    • 要解决的问题:提供一种用于轮毂的轴承装置,其可以在轮毂轮和等速万向接头的锯齿配合中设置和保持适当的配合预载荷,由此齿轮的耐磨性和强度 得到改善,减少了配合的有效长度。 解决方案:用于车轮的轴承装置包括:外部构件25,其在内周包括外侧滚动面; 内部构件,其包括内侧滚动面,所述内侧滚动面包括面向所述外侧滚动面的内侧滚动面; 以及插入在相互面对的滚动面之间的滚动体30。 内部构件由附接到车轮的轮毂轮1和装配到轮毂圈的切口部23的至少一个内轮24和轮毂轮的端部铆接以固定内轮。 在轮毂圈的孔部22的内周形成有母齿42。 在雌性锯齿的形成区域中设置硬化层。 在硬化层H形成和铆接之后,通过用硬质合金拉削工具机械加工形成母体锯齿。 版权所有(C)2013,JPO&INPIT
