| Abstract: | This study involves several isues of flat-topped servounits in a plate-shaped cam mechanism. These include the motional characteristics, lubrication conditions and strength constraints. Furthermore, two deficiency cases, together with theoretical calculations, are presented under hydrodynamical and boundary-frictional conditions. Thereafter,it is found that corrosions and abrasions first occur at the cum top with minimal curvature radius. |
