What is cam and 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. The follower maintains contact with the cam through the force of gravity or by a spring.
What is the application of cam follower mechanism?
Cam and follower are widely used for operating inlet and exhaust valve of I C engine. These are used in wall clock. These are used in feed mechanism of automatic lathe Machine. These are used in paper cutting machine.
What are cam mechanisms?
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.
What are the two types of cam followers?
There are many different types of cam followers available.
- Anti-friction element. The most common anti-friction element employed is a full complement of needle rollers.
- Shape. The outer diameter (OD) of the cam follower (stud or yoke) can be the standard cylindrical shape or be crowned.
What is the function of a cam?
A cam, in its simplest definition, is a mechanical link that converts rotational motion into linear motion, or vice versa. The cams on a camshaft achieve this displacement by the rotation of a radial pattern, and a follower which moves perpendicular to the rotational axis.
What is the difference between cam and follower?
As nouns the difference between cam and follower is that cam is a turning or sliding piece which imparts motion to a rod, lever or block brought into sliding or rolling contact with it or cam can be (informal) camera while follower is (literally) one who follows, comes after another.
What is cam and its application?
Computer Aided Manufacturing (CAM) refers to an automation process that accurately converts product design and drawing of an object into a code format, readable by the machine to manufacture the product.
Why is cam used?
CAM is used – and can be used – to produce almost any item created by a machine or tool. Tool path designs create computer models of new designs. Machining equipment in manufacturing that rely on numerical controls for precision cutting, shaping and packaging. Management of overall production process to drive …
What are the advantages of cam?
Computer aided manufacture (CAM)
|Advantages of CAM||Disadvantages of CAM|
|Fast and accurate production||Expensive to set up|
|Machines can run constantly on repetitive tasks||Needs a skilled workforce of engineers|
Where did the cam and follower mechanism come from?
Alongside, that device was found in the 4th century in Al-jazari design. The Cam and Follower Mechanism is mostly used in the IC engines for driving the valves. Apart from that, the mechanism is often used by engineers as a part of the I.C.Es timing system.
Which is an example of a cam and follower?
Internal Combustion Engine to close and open the outlet valve and intake valve. Automated Types of machinery, Cam and Follower are used in different parts which are automated in motion. In Hydraulic Systems, the main mechanism is Cam and Follower mechanism. In that case, the mechanism is dependent on the fluid pressure.
What kind of follower is used in an engine?
The curved faced or spherical faced followers are used in automobile engines. With flat followers, it is obvious, essential that the working surface of the cam should be convex everywhere. The working contour of a cam which comes into contact with the follower to operate it is known as the cam profile.
Which is the correct description of the cam mechanism?
Cam Mechanism: Cam is a mechanical component which is a rotating circle or eclipse about the minor axis of the Follower. Hence it can be explained easily that Cam is a mechanical component that transmits reciprocating, oscillating or linear motion to Follower. Cam’s shape is usually an oval or an imperfect circle or an eclipse.
