1) Explanation of operation
(1) Relative positions of the roller gear cam and turret w/cam follower are
illustrated below.
(2) Cam indexing angle
A cycle (360°) of the cam groove comprises a retention (straight) area and an
indexing (curved) area. In the retention section, the output section does not
travel even if the cam is rotating. It travels when the cam follower is in the
indexing area and the cam is rotating. The rotating angle of the cam
corresponding to this travel is called an indexing angle.
