In a cam follower system,the motion of the follower is very important. Its displacement can be plotted against the angular displacement θ of the cam and it is called as the displacement diagram. The displacement of the follower is plotted along they-axis and angular displacement θ of the cam is plotted along x-axis.
What are the types of follower?
Types of follower according to Shape
1) Knife-edge Follower.2) Roller Follower.3) Flat-faced Follower.4) Spherical Follower.1) Translatory motion type follower.2) Oscillatory motion type follower.1) Radial Follower:2) Offset Follower:
How many motions can followers have?
These four are rotary, oscillating, linear and reciprocating.
What are the different types of cam followers?
Types of Follower:
Knife edge follower.Roller follower.Flat-faced follower.Spherical follower.Radial follower.Offset Follower.
What are the three types of follower motion?
Uniform velocity, Simple harmonic motion, Uniform acceleration and retardation, Cycloidal motion.
What are the three types of events that form a follower motion?
When the cam turns through one motion cycle, the follower executes a series of events consisting of rises, dwells and returns. Rise is the motion of the follower away from the cam center, dwell is the motion during which the follower is at rest; and return is the motion of the follower toward the cam center.
What are the roles of a follower?
A follower can provide strength to the leader by supporting the leader and by contributing to the organization in areas that complement the leader’s position.
How many types of cams are there according to motion?
It has two types one is concave surface and other is convex surface type. A circumferential cut is made on the periphery of the cam for the rotation of the follower.
What is roller follower?
The Roller Follower is a compact and highly rigid bearing system. It contains needle bearings and is used as a guide roller for cam discs and straight motion. Since its outer ring rotates while keeping direct contact with the mating surface, this product is thick- walled and designed to bear an impact load.
What is cam follower mechanism?
A cam and follower mechanism is a profiled shape mounted on a shaft that causes a lever or follower to move. Cams are used to convert rotary to linear (reciprocating) motion. As the cam rotates, the follower rises and falls in a process known as reciprocating motion.
What is a knife edge follower?
[′nīf ‚ej ′kam ‚fäl·ə·wər] (design engineering) A cam follower having a sharp narrow edge or point like that of a knife; useful in developing cam profile relationships.
What are the 4 main types of cam?
Cams
Circular. Circular cams use an off-centre pivot to cause the follower to move up and down. Pear. Pear cams are called this as they have the shape of a pear. Snail or drop. Snail or drop cams have the appearance of a snail shell. Heart-shaped or constant velocity.
What are the 6 types of cams?
Types of Cams
Wedge or flat cam.Disk or Plate cam.Spiral cam.Cylindrical cam.Heart-shaped cam.Translating cam.Snail drop cam.Conjugate cam.
What is eccentric cam?
An Eccentric Cam would normally provide the follower with Simple Harmonic Motion – (this can be defined as the projection of a point on the diameter of a circle as it precesses around it with constant angular velocity).
