Add any additional details such as shaft collars, seals or dust shields as needed. Place the gage to measure the cam profile. Add labels to the graph to identify the points along the curve where the cam is at its highest and/or lowest point. F is welded onto the follower because turning the roller does not If the clutch is an old clutch, then uniform rate of wear assumption is more valid. L Draw a small line perpendicular to the first line near one of its ends. Calculate the angle corresponding to each point by dividing the displacement by the circumference of the cam's circle of rotation. Draw a line that goes up from the end of the curved line at a certain point. 50 Follower, Basic Kinematics of Constrained Rigid Bodies, Disk Cam with Knife-Edge 4 This line should not be completely symmetrical, as you want the cam to appear uneven. urve is continuous.
