Write the classification of follower (i) As per shape (ii) As per motion. Draw sketch of any one follower.

Classification of follower:
i) As per shape:
•
Knife-edge follower: When the contacting end of the follower has a sharp knife edge, it is
called a knife edge follower.
• Roller follower: When the contacting end of the follower is a roller, it is called a roller follower.
• Flat faced or mushroom follower: When the contacting end of the follower is a perfectly flat
face, it is called a flat faced follower and when the flat faced follower is circular, it is then called a
mushroom follower.
•
Spherical follower: When the contacting end of the follower is of spherical shape, it is called a
spherical faced follower.
ii) As per motion:
•
Reciprocating or translating follower: When the follower reciprocates in guides as the cam
rotates uniformly, it is known as reciprocating or translating follower.
•
Oscillating or rotating follower: When the uniform rotary motion of the cam is converted into
predetermined oscillatory motion of the follower, it is called oscillating or rotating follower.
