    摘要: A method for forming a lightweight axle shaft (10) and an axle shaft (10) are provided. A first tubular blank (36) is inserted in a die (38) defining an extrusion throat (50) at one end (48). A tool (52) is inserted into the die (38) having a mandrel (56) with portions (60,62) of increasing diameter. The tool (52) is moved towards the outlet end (48) of the die (38) to partially extrude the blank (36) through the extrusion throat (50) and form a hollow axle shaft (10) having a variable inner diameter based on the varying diameter of the mandrel (56). The tool (52) is then removed and a second tubular blank (36A) is inserted and placed in engagement with the first blank (36). The tool (52), or a different tool (68), is inserted into the die (38) and again moved towards the outlet end (48) of the die (38) to complete extrusion of the first blank (36) and produce a shaft (10) having diameters at each end (18,20) that are less than the diameter of an intermediate portion (28,29) of the shaft (10).

    摘要: A ring member (1) is made of a steel material a rod member (W), which has been rolled so as to have a sectional shape of the ring member (1), with end faces of its opposite ends being joined together. This joining is accomplished by means of a liquid phase bonding such as, for example, welding. The ring member (1) is rendered to be a raw material before a mechanical process is applied for the bearing ring of a rolling bearing assembly. In such case, the ring member (1) has to have an annular groove (3) that is processed to a raceway groove of the rolling bearing assembly. A strengthening treatment through a friction stir welding is applied to a joint (1a) after a rough turning process has been applied to the ring member (1) so as to have a sectional shape resembling to the sectional shape of the bearing ring.

    摘要: The radial foil bearing (3) for supporting a rotary shaft (1) includes a cylindrical top foil (10) disposed to face the rotary shaft (1), a back foil (11) disposed on a radially outer side of the top foil (10), and a cylindrical bearing housing (12) accommodating the top foil (10) and the back foil (11). The back foil (11) is formed in a cylindrical shape using at least one back foil piece (11a). The back foil piece (11a) includes peak portions (11c) and valley portions (11b) which are alternately formed in a circumferential direction of the top foil (10) and is fixed to the bearing housing (12) at an intermediate portion between both end portions in a circumferential direction of the back foil piece.
