Embodiment Construction
[0021] figure 1 A schematic cross-sectional view of a preformed bearing shell 1 is first shown in . The bearing shell comprises side panels 2 and a bottom region 3 . further by figure 1 It can be seen that the bottom region 3 is slightly arched and that the bearing shell is additionally provided with a collar 4 .
[0022] Figure 2a ) and 2b) a first embodiment of the method according to the invention is shown. Firstly, the drawing schematically shows a die 5 with a die 6 which, together with a punch 7 , can deform the bearing shell 1 , which is now already flangeless, into its final shape. Depend on Figure 2a ) shows that the punch 7 presses the bottom region 3 and the side plate 2 on the bearing shell 1 during the deformation process due to the preforming of the bearing shell 1 . As a result of this calendering process a material flow is formed which roughly corresponds to the Figure 2a ) shows the direction of the arrow. On the one hand, the wall thickness of the ...
