The diagram depicts an acceptable example of a single-dwell cycle. Once a suitable output motion is defined, the profile of the cam itself can be generated, often through special software. Obviously, the follower begins and ends the cycle at the same position. In a valid follower motion, the velocity and acceleration will remain continuous throughout the cycle otherwise the device produces an impossible, infinite amount of jerk.
Rocker followers often approximate straight-line motion adequately while remaining fixed about their arms. This can be used to help distribute wear by offsetting a flat-faced follower.Ī follower with a wheel-type contact, though, must remain aligned. Pointed followers can be useful for detailed cam profiles, but are subject to wear and generate high contact stress. In a simple case, it may have to move to a critical position on time while maintaining velocity andor acceleration parameters, hold this position, or dwell, for a set time, and return to the original position under a different set of velocityacceleration parameters.įollowers that slide along the cam, such as flat-faced or pointed, generate more friction than rolling followers, but are attractive due to size and simplicity.įlat-faced followers resist jamming, but cannot trace concave cam profiles. However, cams go beyond the function of linkage mechanisms, allowing a tremendous range of possibilities for the output motion. Where this overlap occurs, the cam usually provides the quicker design solution while presenting a more difficult manufacturing prospect.
The follower may move as a slider, reciprocating in a linear direction, or as a rocker, oscillating around a fixed pivot. This is accomplished by keeping one or more followers in contact with the surface of a rotating cam.
