  • Connection between two transmission components having round cross-sections, for the support of axial forces
    Patent number: 7819774
    Abstract: A positively-locking connection between two components of a transmission that have round cross-sections, designed to support axial forces. A first component to be connected has an annular flange with windows stamped out around its circumference. The windows enable simple deformation of the annular flange. The second component to be connected has an annular groove such that after bringing the two components together, the annular flange of the first component, when viewed axially, is positioned over the annular groove of the second component, such that the annular flange of the first component can be pressed radially into the annular groove of the second component so that segments of the annular flange radially engage the annular groove.
