What is a barrel cam used in?

Barrel Cam with milled grooves is used in sewing machines to guide thread.

What is a cam and follower used for?

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.

Where is a cylindrical cam used?

These unusual cams are normally composed of a cylinder which has a groove cut out of its surface and it is in this that the follower runs up and down. This type of cam can be seen in some old clock mechanisms and still in modern sewing machines. Machines that perform repetitive movements may use a cylinder cam profile.

What is a barrel cam?

A cylindrical cam or barrel cam is a cam in which the follower rides on the surface of a cylinder. In the most common type, the follower rides in a groove cut into the surface of a cylinder. These cams are principally used to convert rotational motion to linear motion parallel to the rotational axis of the cylinder.

What is follower in mechanical engineering?

A follower is a mechanical element with respect to which the cam rotates in an oscillating or circular motion. The follower prevents the push and pulls of the cam. The followers are used to transfer the movement to the required machine part.

What is the function of cam?

A camshaft acts as a timing device that controls the opening and closing of the intake and exhaust valves, as well as setting the valve overlap that occurs at the top dead centre on the exhaust stroke.

What are the applications of cam?

Some of the major applications of the CAM system are glass working, woodturning, metalworking and spinning, and graphical optimization of the entire manufacturing procedure. Production of the solids of rotation, plane surfaces, and screw threads is done by applying CAM systems.

What is cylindrical cam?

A cylindrical cam is a 3D cam which drives its follower in a groove cut on the periphery of a cylinder. The follower, which is either cylindrical or conical, may translate or oscillate. The cam rotates about its longitudinal axis, and transmits a translation or oscillation displacement to the follower at the same time.

What are the application of cam?

What is the use of crankshaft?

The crankshaft is essentially the backbone of the internal combustion engine. The crankshaft is responsible for the proper operation of the engine and converting a linear motion to a rotational motion. Crankshafts should have very high fatigue strength and wear resistance to ensure long service life.

What does a cam do for performance?

Adjusting the camshafts so the cams are slightly ahead or behind will alter the engine’s performance. Advancing the timing will cause the fuel intakes to open and close earlier, which improves low-end torque. Conversely, retarding the cam will improve high-end horsepower at the expense of low-end torque.
