    摘要: A method of creating a piston crown is disclosed. The method includes the step of providing a billet and then upsetting the billet in a first station to generally decrease a length of the billet and generally increase a cross section of the billet. The billet is then pre-formed in a second station into an intermediate configuration of a piston crown, where the piston crown is in a preliminary shape. The first station and the second station are separate components. The intermediate configuration of the piston crown is formed into a final shape of the piston crown, where the final shape includes a predetermined volume. The piston crown is then precision formed into a near net shaped configuration, where the near net shaped configuration of the piston crown includes a near net shaped volume. The predetermined volume may be approximately equal to the near net shaped volume.

    摘要: A half bearing and a method of manufacture of a half bearing are described. The half bearing 100 comprises a bearing member 102 having a strong external backing layer of steel or bronze 104 and an internal bearing lining layer 106 of a suitable bearing alloy with an optional bearing overlay layer (not shown) defining a concave substantially semi-cylindrical bearing surface 112 extending between first and second axial ends 110A, 110B of the half bearing 100. The bearing lining layer 106 is provided with at least first and second polymer seals 108A, 108B at or adjacent to the first and second axial ends 110A, 110B. The first and second polymer seals 108A, 108B project from and are formed directly on the bearing lining layer 106 and extend at least partially circumferentially across the bearing lining layer 106. The bearing member 102 has joint faces 113A, 113B, which locate with corresponding joint faces of a further half bearing to form a 360° bearing assembly.

    摘要: A thrust washer (100) for a flange half-bearing, the thrust washer comprising: a substantially semi-annular panel (102) having an inner edge (108) and outer edge; and hooking lugs (110) projecting inwardly from the inner edge of the panel, wherein the hooking lugs have latching edges (118) that are configured to engage within corresponding openings in a bearing shell received by the thrust washer and to prevent disconnection of the thrust washer and bearing shell without deformation of the bearing shell, each hooking lug has a hooking lug inner portion (104A) proximate, around the inner edge of the panel, to the central part of the thrust washer for engaging against edges of the openings in the bearing shell and a hooking lug outer portion (104B) remote, around the inner edge of the panel, from the central part of the thrust washer, and the hooking lug inner portion is thinner than the hooking lug outer portion.
