Abstract: An assembly of crown wheel (12) and casing (11) of a differential gear assembly (10) is adapted to welding. The casing (11) has a circular flange (17) with an axially extending lip engaged in a circular groove (33) which is further relieved at the radially outer side to give clearance for a high energy welding beam (13). The interface between crown wheel (12) and flange (17) is preferably a frusto-conical surface (70, 65) which presents an oblique angle to said welding beam.

Abstract translation: 差速齿轮组件（10）的冠轮（12）和壳体（11）的组件适于焊接。 壳体（11）具有圆形凸缘（17），其具有接合在圆形凹槽（33）中的轴向延伸的唇部，该圆形凹槽（33）在径向外侧进一步释放，以为高能量焊接梁（13）提供间隙。 冠轮（12）和凸缘（17）之间的界面优选为与所述焊接梁呈倾斜角度的截头圆锥形表面（70,65）。
