Camshaft assembly and method
A method is described of manufacturing a camshaft assembly for internal combustion engines and the like. The method includes the steps of: providing cam and journal elements, the elements each including an axial opening, securing the elements in predetermined fixed orientation and spacing with the openings aligned on a common axis, inserting a hollow tube into the elements, in close fitting relation with openings, and expanding the hollow tube into mechanical interference engagement with all the element openings to secure the elements permanently onto the tube in the predetermined orientation while forming within the tube a uniform smooth sided interior cross-sectional configuration by forcing through the tube an element sufficiently larger than the tube inner diameter to outwardly deform the tube wall in the required degree.
