ABSTRACT:
Camshaft assemblies, methods and apparatus are provided for making camshafts by the expansion of tubular shafts into prelocated cams, journals and other elements, if desired. Features of the camshafts include trilobe or polylobe element openings, preferably splined or serrated for low energy filling and high torque capacity and high strength low alloy mild steel tubular shaft material. The method emphasizes trapping, or loading, the shaft to prevent axial lengthening during expansion such as by mechanical ballizing. The apparatus includes adjustable thrust blocks and locating plungers with incorporated flush pin gages together with hydraulic or other loading means all for use in carrying out the assembly method with various benefits from the incorporated features.
