As the input shaft spins, the rollers in the cam splitter engage the output turret, following the predetermined displacement curve while smoothly gliding along the bevel of the ribs. In the zone where the rib meets the cam face, also known as the static range, the rollers link their shafts, yet the output turret remains stationary. The taper support ribs typically engage with two or three cam rollers, making sure that the rotation of the input shaft smoothly transfers to the output shaft.
If there's a rough patch between the cam surface of the taper support rib and the cam rollers, it could lead to some serious damage to the splitter. By twisting the eccentric housing that holds the input shaft, you can tweak the gap between the high-speed input shaft and the output shaft, totally getting rid of any roughness. Basically, tweaking the distance between those high-speed shafts can totally fix that bumpy rotation issue. Moreover, you can amp up the stiffness of the split zone by cranking up the speed during preloading, getting it nice and close to the cam's elastic zone.
