When designing split cams that must be changed or replace  d in the field in order to eliminate disassembly you can minimize the noise and wear caused by misalignment of the mating surfaces. Shown here is one example of the method used by Mallory on precision cams that must run at higher speeds, without any increase in noise and no interruption on the cam surface. This method insures better distribution of loads at the intersections of the split surfaces. A gap is usually left in the split to facilitate clamping. Similar methods to this can be applied to most cams with variations in the method of splitting the cam. |
