2. Mechanical toy - Wikipedia

   en.wikipedia.org/wiki/Mechanical_toy

   Mechanical toys use several types of mechanisms, because Cam toys are powered by a very large cam and even bigger cam follower which transfers the cam rotation to the working area of the toy. The cam is unevenly rotated by placing the rotator out of the ideal center. This transforms the circular motion into motion that moves up and powers the ...

3. Dwell mechanism - Wikipedia

   en.wikipedia.org/wiki/Dwell_mechanism

   Cam-follower dwell mechanisms are used in pairs in sewing machines to operate the four motion feed dogs, with one cam moving the dog up and down, and the other cam moving the dog forwards and backwards. The cams in this application are usually phased 90 degrees apart allowing a pause in the up/down movement of the dog while it is being moved ...

4. Cam (mechanism) - Wikipedia

   en.wikipedia.org/wiki/Cam_(mechanism)

   The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.

5. Kinematic synthesis - Wikipedia

   en.wikipedia.org/wiki/Kinematic_synthesis

   A cam and follower mechanism uses the shape of the cam to guide the movement of the follower by direct contact. Kinematic synthesis of a cam and follower mechanism consists of finding the shape of the cam that guides a particular follower through the required movement. [15] Examples of cams with a knife edge, a roller and a flat-faced follower

7. Cam follower - Wikipedia

   en.wikipedia.org/wiki/Cam_follower

   A cam follower, also known as a track follower, [1] is a specialized type of roller or needle bearing designed to follow cam lobe profiles. Cam followers come in a vast array of different configurations, however the most defining characteristic is how the cam follower mounts to its mating part; stud style cam followers use a stud while the yoke style has a hole through the middle.
