Abstract:
In an assembly wherein a component is secured on a spindle by a deformed spindle annular end portion, the spindle having an outer cylindrical spindle surface and an inner spindle surface and the annular end portion having an internal surface, the component having an opening in which the spindle is received for rotation of the component with the spindle, the spindle annular end portion having a formed end that is outwardly deformed into engagement with an end face of the component to secure the component on the spindle, the formed end extending outwardly at 90Â° to the spindle axis, the formed end having an inside end surface that engages the end face of the component and merges into the outer cylindrical spindle surface at an inside intersection, the formed end having an axially facing outside end surface that merges into the internal surface of the spindle annular end portion along an outside intersection, characterized in that the outside intersection is not a continuous smooth curve and cuts across between the internal surface of the spindle annular end portion and the axially facing outside end surface of the formed end closer to the inside intersection than would a continuous smooth curve to provide the formed end with a reduced thickness in a direction diagonally across the inside and outside intersections.
