Abstract
A part, providing its own plastic deformation method and an exemplary embodiment, a polycarbonate spur gear, is disclosed. In a part having at least one region adapted to be deformed due to press-fit forces acting upon said region deformation is decoupled from proximate critical surfaces by providing at least one aperture in said part in a second region which is spaced from said first region in the general direction of the resultant vector of said forces such that said deformation is relieved by said aperture. In its basic aspects, an exemplary embodiment of the present invention, a plastic spur gear which remains rotationally concentric by embodying the inventive concept is described.
