In this type of follower, the line of movement passes through the center of the camshaft. Mainly the movement of the follower is in line. The follower is in a reciprocating motion.

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.

A cam is a reciprocating, oscillating, or rotating body that imparts reciprocating or oscillating motion to a second body, called the follower, with which it is in contact.

A spherical cam is in the form of a spherical shape on which a groove is made. The follower has surface contact with this groove. As the cam rotates follower oscillates about a fixed point.

It can have a uniform velocity or can have uniform acceleration motion. Complicated output motion can be achieved with the help of the follower motion.

It is often part of a rotating wheel (e.g. an eccentric wheel) or a shaft (e.g. a cylinder with an irregular shape) that hits a lever at one or more points on its circular path.

In this category, followers are classified by the relative motion and movement between cam and follower these are as follows.

Types ofcamandfollower

The cylindrical cam has a groove cut along its cylindrical surface. The roller follows the groove, and the follower moves in a plane parallel to the axis of rotation of the cylinder.

Cam followerbearing

When it comes to transforming rotary and vibration motion into linear, there’s rarely a better and more appropriate mechanism than a cam and cam follower assembly.

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.

In this type, follower movement is considered. As per name follower movement is done in a way that first rises and then returns. This process is done in one rotation (360 degrees) of the cam.

The cam can be a simple tooth, such as is used to give pulses of power to a steam hammer, or an eccentric disc or other shapes that allow a gentle reciprocating motion in the follower, which is a lever making contact with the cam.

Application ofcamandfollowerPDF

A cam and follower mechanism is a profiled shape mounted on a shaft that causes a lever or follower to move. Cam and follower are used to convert rotary motion into linear (reciprocating) motion.

This type of cam looks like an asymmetric heart. It is mainly used to return a shaft to hold the cam to a set position by its pressure from a roller.

In this type, follower movement is considered. As per the name follower movement is done in a way that first dwells then rise then again dwells. This process is done in one rotation (360 degrees) of the cam. And at 360 degrees it suddenly falls to its first position.

Globoidal cam is a shaft and has a concave or convex circumference. Which groove is made by machining and this groove use for giving movement to the follower. Globoidal cam use for oscillating followers about a fixed point.

In this article, we’ll discuss cam followers, what exactly they are, what are the different types, and how they’re classified using different classification criteria.

In this type, follower movement is considered. As per the name follower movement is done in a way that first dwells then rise again dwells then return and again dwells. This process is done in one rotation (360 degrees) of the cam.

The spiral cam consists of a semi-circular or a spiral that shapes the Grooved contour, the cam moves in a reciprocating motion and the follower moves perpendicular to the axis of the cam.

A CAM is a rotating machine element that gives reciprocating or oscillating motion to another element known as a follower.

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.

In these types two discs connect to each other and the axes of discs are offset by the distance, to form a cam profile. The follower has surface contact with a cam profile by two rollers. As the cam rotates followers follow it.

A follower is a translating or oscillating mechanical member that follows the motion of the cam. It can touch the surface profile of the cam or can be spring-loaded.

In this type of follower, the follower has an oscillating motion. Cam rotates and as per the cam profile follower also moves but the follower is fixed at the point about which the follower is oscillating. This type of follower is called an oscillatory motion type follower.

In this type, follower movement is considered. As per name follower movement is done in a way that first dwells then rises then returns and again dwells. This process is done in one rotation (360 degrees) of the cam.

The translating cam is a contoured or grooved plate sliding on a guiding surface(s). The follower may oscillate or reciprocate. The contour or the shape of the groove is determined by the specified motion of the follower.

Cam and cam follower mechanisms are often used in mechanical engineering and various machinery, like internal combustion engines, automatic lathe machines, diesel fuel pumps, and other repeating machinery and manufacturing applications.

This type of follower looks like a flat surface with an irregular cam. This type of cam is used when the space is limited and this follower can resist more side thrust. This follower can also be used in a precision application.

In this type of cam, the spring force is used. The compression spring is preloaded into followers in such a way that it maintains surface contact at all times.

Cam with followerdiagram

In these category types of the cam is classified as per the movement of the follower. The movement of followers is depending upon the cam profile for this; cams are also classified according to follower movement.

Cams are specifically designed rotating components that are used to transform rotary motion into linear motion. They’re driving the cam follower (driven member) that internally connects to the cam.

A follower is a mechanical component concerning which, the Cam rotates in an oscillatory or circular motion. The follower inhibits the push and pull of the Cam.

A follower is used to transfer the motion to the required machine part. The follower rotates in an oscillating or circular arc.

In an IC engine the valves have to be kept open; first, then close it and keep it closed, all these timing operations can be easily set by having cam-follower mechanisms. In the case of linkages, we study planar linkages or two- dimensional linkages, and more.

For the smooth functioning of a cam-follower mechanism, the follower must move smoothly without requiring too much input power, which means the follower should not jam, during its movement.

MAG1 multi-purpose grease provides outstanding lubrication and protection in a wide range of temperatures, operating conditions and applications. Made of fine quality base oils, lithium, 12 hydroxy-stearic acid and additive systems.

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.

This type of follower mainly uses in high-speed operation because it has smooth contact with the surface. This type of follower has less wear and tear as compared to the other followers.

A cam is a rotating element that gives oscillating or reciprocating motion to the follower, another element of this machine by direct contact.

A cam is a rotating or sliding piece in a mechanical linkage, which is used in particular to convert a rotary motion into a linear motion.

Camandfollowerexamples

The disc (or plate) cam has an irregular contour to provide a specific motion to the follower. The follower rotates in a plane that moves on the axis of rotation of the camshaft and is placed in contact with the cam by springs or gravity.

Types ofcamandfollowerpdf

When we study about cam follower mechanism, some common terminology like a prime circle, base circle, pressure angle, etc. are used to describe a cam.

The mechanism for Cam and the mechanism for Followers depend upon each other so the main mechanism of Cam and Followers. The mechanism is essential in the engineering field and has many different functions for different machines.

This type of follower has a curved but regular follower as well as cam. This is a modification of a flat-faced follower.

A cam timer is similar and was widely used to control electrical machines before the advent of inexpensive electronics, microcontrollers, integrated circuits, programmable logic controllers, and digital controls (an electromechanical timer in a washing machine is a common example).

In this type of follower, followers have translatory motion means the cam is rotating and the follower reciprocates between the guideway. Example of this type of follower is knife-edge follower, roller follower, flat follower, and spherical follower.

This type of cam, it does not require any external force. The follower is designed in such a way that it does not require any external force.

This type of follower has a sharp area of contact with the cam. This is the simplest among all of the followers and these kinds of followers are not in use in the case of fast applications, because of its sharp edge.

The cam profile is designed to achieve the desired motion, and its varying cross-section makes the cam follower reciprocate.

The shape of the cam depends upon its own motion, the required motion of the follower, and the shape of the contact face of the follower.

There are different types of surface contact between cam and follower and according to surface contact they are classified as follows:

For proper functioning of the cam and follower mechanism, it is important to keep the surface contact between the cam profile and the follower at all times of rotation and any motion. For this, spring force, gravitational force, or positive drive are used in the cam and follower mechanism. On this basis, cams are classified based on the type of follower and are as follows.
