  • Camshaft and method of making a camshaft
    Patent number: 5469759
    Abstract: A camshaft and method of manufacturing thereof wherein the camshaft has a plurality of first zones having a plurality of circumferentially spaced thicker wall segments and a plurality of thin wall sections. Axially spaced cams are mounted on a hollow tube about the zones. The thicker wall segments are deformed outward to mechanically secure the cams to the hollow tube. The outer diameter of the hollow tube thin wall sections are not deformed when the thicker wall segments are deformed.
    Type: Grant
    Filed: December 5, 1994
    Date of Patent: November 28, 1995
    Assignee: The Torrington Company
    Inventor: Louis V. Orsini, Jr.

  • Method of making a camshaft
    Patent number: 5337476
    Abstract: A method of forming a camshaft tube having a plurality of thinner wall sections adjacent to thicker wall sections. The diameter of a hollow tube is mechanically reduced with a retractable mandrel inserted in the hollow tube. The retractable mandrel has a first portion having a larger diameter than an adjacent second portion. To form a thinner wall section, the larger diameter first portion is positioned under a reducing tool. To form a thicker portion, the smaller diameter second portion is positioned under a reducing tool.
