Where Is A Cam And Follower Used In Real Life?

Where are cam mechanisms used?

Cam mechanisms are used in various areas of machine building, such as internal-combustion engines, metal-cutting machines, and machines of the food industry, in which the cam mechanism performs a programmed operation, as well as in automated machines, in which cam mechanisms perform control functions, connecting and ….

What are the three types of CAM?

Cams can be produced in any shape, but the most common shapes are: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. … Heart-shaped or constant velocity.

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 is CAM and its types?

A cam is a mechanical device used to transmit motion to a follower by direct contact. The driver is called the cam and the driven member is called the follower. In a cam follower pair, the cam normally rotates while the follower may translate or oscillate.

What are the different types of CAM?

There are various types of cams available, that are listed below:Disk or Plate cam.Cylindrical cam.Translating cam.Wedge cam.Spiral cam.Heart-shaped cam.

How do cam followers 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 purpose of a cam follower?

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.

How many types of cam followers are there?

1. (A) According to type of shape (1) Radial or Disc cam (2) Cylinrical cam (3) Translation or Wedge cam (4) Conjugate cam (5) Globoidal cam (6) Spherical cam Types of cams…

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.

What is cam lobe?

Cams located on the camshaft that open and close the intake and exhaust valves in time with the motion of the piston. Cam lobes control the valve lift, and there is a direct relationship between the shape of the cam lobes and the way the engine performs in different speed ranges.

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 a cam in mechanics?

Cams are mechanical devices used to convert the rotation of a shaft into simple or complex reciprocating linear motion. They can be sliding or rotational pieces in a mechanical linkage.

Why offset is provided in Cam?

Offsets are required in cam and followers to reduce wear and side thrust. … Less stroke length means follower movement will be less. Due to less movement of follower, spring will also be compressed less. Therefore spring offer less reaction force to follower that will give condition of less wear and thrust.

3. What is the following term not related to cam? Explanation: Base circle is the minimum rise contour that follower can make from cam profile. Rise and fall are the movement of follower as per profile of cam.

Where is a cam and follower used?

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 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 other things use a cam mechanism?

Cams are commonly used in engines to control valves (in which the valve is the follower), sewing machines, children’s toys and many other mechanical applications. The shapes of individual Cams are designed to produce specific types of motion.
