Mell What is a cam used for?
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.
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 cam profiles?
The camshaft profile refers to the shape of the individual lobes. The camshaft pattern refers how the profile of the intake and exhaust lobes compare to each other.
What is cam and its types?
A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path.
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.
Which type of follower is the most accurate?
Point or knife followers have a narrow point that sits on the cam. These are very accurate and low friction but are quick to wear away the pointed edge.
What do you need to know about cams?
It is a therapeutic framework for suicide-specific assessment and treatment of a patient’s suicidal risk. It is a flexible approach that can be used across theoretical orientations and disciplines for a wide range of suicidal patients across treatment settings and different treatment modalities. This is the first time I’m hearing about CAMS.
Why do you need a cam in a sewing machine?
Cams are essential elements in automatic machine tools, textile machinery, sewing machines, printing machines, and many others. If the follower is not restrained by a groove on the cam, a spring is necessary to keep the follower in contact with the cam.
What does the machine component in a cam do?
Cam, machine component that either rotates or moves back and forth (reciprocates) to create a prescribed motion in a contacting element known as a follower.
How are cams used in all branches of Engineering?
Introduction Cams come in all shapes and sizes and are found in most branches of engineering. Indeed without them many of our everyday appliances would not work.
