Abstract
A non-homogeneous cam includes an eccentric disk having side surfaces with an opening therethrough, and a cam surface disposed between the side surfaces. A first radius extending from a point within the opening to a number of first portions of the cam surface and second radii extending from the point to second portions of the cam surface define the cam surface. The first radius is greater than each of the second radii. The cam surface includes a first cam surface generally having the first radius and a second cam surface having a plurality of the second radii. The first and second cam surfaces define an angle of less than 90 degrees. The eccentric disk is generally made of a first material having a first strength. A portion of the eccentric disk between the first and second cam surfaces is made of a different second material having a greater second strength.
