  1. Structures and Mechanisms

  2. Follower Cam Cam and Follower • The cam and follower is a device which can convert rotary motion (circular motion) into linear motion (movement in a straight line). Cams Followers (valves)

  3. Cam and Follower follower • The cam can have various shapes. These are know as cam profiles. Cam Pear Heart Circular Drop

  4. Cam and Follower Follower • A follower is a component which is designed to move up and down as it follows the edge of the cam. cam Knife edge Follower Flat foot follower Off set follower Roller follower

  5. Cam and Follower Follower • The 'bumps' on a cam are calledlobes. • The square cam illustrated has four lobes, and lifts the follower four times each revolution. Square cam Examples of other rotary cam profiles.

  6. Cam and Follower Examples of a Rotary cams in operation. Cams used in a pump. Control the movement of the engine valves.

  7. Linear cam Cam and Follower • The linear cam moves backwards and forwards in a reciprocating motion. Cam Follower Distance moved by the follower

  8. Cam rise and Fall Max Lift Min Lift Cam and Follower • Cams can also be cylindrical in shape • Below a cylindrical cam and roller follower. • The cam follower does not have to move up and down - it can be an oscillating lever as shown above.
