What are the 5 types of followers?

Kelley (1992) posited that there are five followership styles. These include exemplary, conformist, passive, alienated and pragmatist styles (Kelley, 1992). These followership styles are based on a combination of two different followership dimensions: engagement and critical thinking (Kelley, 1992).

What is meant by cam and follower?

DEFINITION. Cam is a mechanical element which is used to deliver the reciprocating or oscillating motion to another machine element known as follower. Cam and follower is a type of assembly, both works together in any machine element. Cam and followers are the example of higher pair due to the line contact between them …

What is circular cam?

A circular cam is made by mounting a circular plate on a camshaft at some distance d away from the circle center (Figure 4.8). This gives the simplest cam profile. The eccentric attachment of the circular plate produces a reciprocating motion of the follower.

What is the difference between cam and follower?

Followers move vertically to the axis of the cam when the cam moves in a reciprocating motion. The follower is a part of a machine that follows the cam that is either oscillating or reciprocating in motion. In brief, a driver member is a cam, while a driven member is known as the follower.

What are the three types of 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.

How many types of cam and follower are there?

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. The working of both convex and concave type’s surfaces is same but applications are different. The follower has oscillating motion.

How many type of follower are there?

Kelley developed a theory of followers describing five types: Conformist, Passive, Alienated, Exemplary and Pragmatic.

What are the different types of follower motion?

Uniform velocity, Simple harmonic motion, Uniform acceleration and retardation, Cycloidal motion.

How are followers classified?

Roller follower: When the contacting end of the follower is a roller, it is called a roller follower. mushroom follower. spherical faced follower. rotates uniformly, it is known as reciprocating or translating 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.

Which type of cam follower is used in automobiles?

knife edge follower.

What are the different types of cam used in IC engines?

• Camshaft.
• Displacement diagram.
• Disc or plate cam.
• Cylindrical cam.
• Face cam.
• Heart shaped cam.
• Snail drop cam.
• Linear cam.

What offset followers?

Offset follower: The center line of the follower does not pass through the center line of the cam shaft. The amount of offset is the distance between these two center lines. The offset causes a reduction of the side thrust present in the roller follower.

What is 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 is a radial cam?

Radial Cams are one of the most common types of ‘cam’. The ‘radial cam’ is a rotating plate or disc with an outer circumference shaped to produce a required movement (usually linear) to a ‘follower’ which is held against it.

What is a tangent cam?

Tangent cam (with roller follower) A tangent cam is symmetrical about the centre line. It has straight flanks (such as AK in figure) with a circular nose. The centre of cam is at O and that of nose is at Q.

What is an example of a cam and follower?

The cam and follower mechanism is widely used for operating the inlet and exhaust valves of internal combustion engines. They are used in wall clocks and the feed mechanism of automatic lathe machines. They are also used in paper cutting machines and weaving textile machinery.

What is a radial follower?

Explanation: In radial cams, the follower reciprocates or oscillates in a direction perpendicular to the cam axis. … Explanation: When the motion of the follower is along an axis passing through the centre of the cam, it is known as radial follower.

What is a cam follower mechanism?

Cams. 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.
