Quick Answer: What Is A Knife Edge Follower?

What is side thrust in cam and follower?

Side thrust exists between the follower and the guide.

Rate of wear is reduced.

Side thrust exists between the follower and the guide.

It is used where more space is available such as in stationary gas and oil engines and aircraft engines..

What is cam and 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.

What do cam followers do?

Cam follower bearings are also known as track followers. As the name implies, they are essential to make the cam followers work effectively. Cam followers are capable of handling intermittent shock and heavy loads. They also can have a soft core that allows for extreme shock loads without fracture.

What is an example of a cam follower?

A cam follower is a component that is intrinsically tied to a cam. Cams exist in many applications–dishwashers, sprinklers, etc. –but the most well-known example is that of a camshaft in a car. The goal of a cam is to convert rotary motion to linear motion.

What is cam angle?

A. During which the follower returns to its initial position. Of rotation of the cam for a definite displacement of the follower. Through which, the cam rotates during the period in which the follower remains in the highest position.

What is the follower?

A follower is a person who is following another person on a social networking platform, such as Twitter or Instagram. … When following someone, each post that person makes is shown on your timeline or feed. Users who are more familiar with Facebook can think of a follower as a friend.

Where is a knife edge follower used?

The Knife Edge Follower: This is the simplest type, is not often used due to the rapid rate of wear. When it is adopted, it is usually for reciprocating motion, running in slides and there is considerable side thrust, this being a component of the thrust from the cam.

What are the different types of motion with which a follower can move?

The follower may move as a slider, reciprocating in a linear direction, or as a rocker, oscillating around a fixed pivot. There can be overlapping functionality between cams and linkages (such as crank-rockers).

What are the three types of CAM?

CamsCircular. 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 does CAM mean?

Common Area Maintenance chargesCommon Area Maintenance charges, or CAM for short, are one of the net charges billed to tenants in a commercial triple net (NNN) lease, and are paid by tenants to the landlord of a commercial property.

Why is a roller follower preferred to a knife edged follower?

Answer: In case of knife edge follower there is sliding motion between the contacting surface of cam and follower. … Whereas in roller follower there is rolling motion between contacting surfacing and more contact area, therefore rate of wear is greatly reduced.

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).

How does cam follower work?

A face cam produces motion by using a follower riding on the face of a disk. The most common type has the follower ride in a slot so that the captive follower produces radial motion with positive positioning without the need for a spring or other mechanism to keep the follower in contact with the control surface.

What is the difference between a cam and a follower?

Cam followers have a built-in shaft with a grooved end that allows you to screw the part directly into a piece of metal or some other surface. Roller followers, also known as track rollers, require an application to have a shaft or other similar mounting part as part of its design.

What are the different types of CAM?

What are the different types of CAM?Acupuncture.Ayurveda.Homeopathy.Naturopathy.Chinese or Oriental medicine.

What is dwell period in Cam?

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. There are many follower motions that can be used for the rises and the returns.

Which of the following is motion of follower?

follower, during its travel, may have one of the following motions. 1. Uniform motion or uniform velocity, 2. Simple harmonic motion.

What is CAM and its classification?

Classification of Cams Disk or plate cam (Fig. 4.1a and b): The disk (or plate) cam has an irregular contour to impart a specific motion to the follower. The follower moves in a plane perpendicular to the axis of rotation of the camshaft and is held in contact with the cam by springs or gravity.
