What is advantage of cam mechanism?
By designing the appropriate cam profile, the follower can be arbitrarily expected to move, and the structure is simple, compact and convenient to design, so in automatic machine tools, light industrial machinery, textile machinery, printing machinery, food machinery, packaging machinery and Widely used in mechatronic …
What is the main purpose of a cam and follower?
Cam and follower are used to convert rotary motion into linear (reciprocating) motion. As the cam rotates, the followers rise and fall in a process known as reciprocating motion.
Where is a cam and follower used in real life?
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 are the advantages of roller follower than knife edge follower?
Answer: Advantages of roller follower over knife edge follower a) Roller follower has less wear and tear than knife edge follower. b) Power required for driving the cam is less due to less frictional force between cam and follower.
How does a cam and follower work?
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 cam purpose?
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 a follower in a cam?
A cam follower is a component that is intrinsically tied to a cam. Without a cam follower, a cam would not be of much use, as cams must make contact with followers to transfer rotary motion into linear motion. The followers are made with special cam follower bearings to make this transfer possible.
What are the types of cam and followers?
Types of Follower:
- Knife edge follower.
- Roller follower.
- Flat-faced follower.
- Spherical follower.
- Radial follower.
- Offset Follower.
What is use of cam and follower only two application 2 points?
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. Moreover, in the automotive industry Cam-Follower mechanism is used to drive fuel pumps.
What is the difference between roller follower and knife edge 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.
Which is better a cam or follower mechanism?
It is an accurate design mechanism with a higher standard method of motion transformation. the elements used in the mechanism are usually durable and long lasting. Load Carrying capacity of cam and follower is excellent. The higher accuracy of machine element is required. Especially for rotary motion is required as input to the mechanism
How are cams and their followers used in engineering?
Uniform acceleration and retardation cams are used to controls the motion of linkages in complex machinery. There are three types of cam followers, and since the type of follower influences the profile of the cam it is worthwhile considering the advantages and disadvantages of each type.
Why does a flatfoot follower need a cam profile?
Thus the contact with the cam will tend to cause rotation of the follower. The cam profile, to work with a flatfoot follower, must be convex at all parts, in order to prevent the corners of the follower digging into the cam profile. The minimum cam radius should be as small as possible to minimize sliding velocity and friction.
What are the components of a CAM system?
A cam mechanism consists of three elements: the cam, the follower (or follower system), and the frame. The follower is in direct contact with the cam. The cam may be of various shapes. The follower system includes all of the elements to which motion is imparted by the cam.
