The 442C design also offers maximum installation flexibility with its short axial length and flexible gland positioning. It simplifies split mechanical seal repair by using a standard spare parts kit, enabling you to lower your inventory costs to maintain operations.

In an IC engine, the valves have to be kept open; First, then turn it off and keep it closed; all these time operations can be set easily by a cam-follower mechanism. In the case of linkages, we study planar linkages or two-dimensional linkages, and more.

When designing a cam-follower system, translating follower is not jammed into its prismatic guide. The oscillating follower has very little chance of a restriction on its motion.

It serves a general force X direction and serves as a common force Y direction and two normal force balancing Cocking moment, the moment due to the force Fn.

This circle is called the prime circle. If the base circle radius is Rb and Rr is the roller radius, then the prime circle radius is Rp = Rb + Rr.

The cam rotates and its profile pushes against the follower. This interaction converts the rotary motion of the cam into linear or oscillating motion of the follower. The precise shape of the cam determines the movement pattern of the follower.

The Interlocking Face eliminates this problem by uniquely keying the mating halves so that faces align correctly without having to manually work the face halves. Damage associated with handling and additional cleaning requirements are eliminated, which results in greater sealing reliability.

Without a cam follower, a cam would not be of much use, as the cams must contact the followers to transfer the rotary motion into linear motion. Followers are built with special cam follower bearings to make this shifting possible.

A Cam follower is a component that is internally attached to a cam, playing a crucial role in the cam follower mechanism.

Hey, I am Rajkumar. The Man Behind MechanicalJungle. I started this site to spread knowledge about Mechnical Engineering. I am a Degree Holder in Mechanical Engineering.

The follower, a crucial component in the system, can be categorized into types of followers in cam, each with unique characteristics and applications.

This cam is very popular due to its simple design & compactness, which can be fitted in remote locations. Disc or plate cams have applications in IC engines and machine tools.

So the tracepoint is the roller center, which means that the follower’s motion will be described in terms of the motions of this roller center.

If this cam rotates based on the profile or shape of the cam, the follower will have translational motion along with this prismatic pair between the fixed link and the follower. So in the uniform rotational motion of this cam, there will be an oscillation of the follower along with the guide.

Now for a translating follower, i.e., the axis of that prismatic pair passes through the cam center; we call it radial translating. We call this a radially translating follower when the follower axis passes through the center of the camshaft.

A translating cam is a type of cam in which the cam can rotate in a horizontal plane. The follower is also attached, in which the motion is interrupted with the help of a spring. Sometimes groove cams are used in which follower motion is achieved without the use of a spring.

The other has a cylinder as the working surface. In this type of cam, the spring-loaded follower translates into a cylinder rotating along the parallel axis.

The follower surface that is in contact with the cam as a flat surface is called a flat face follower. The trailing surface may also be a curved surface rather than a plane. It is the cam that rotates and the follower that rests here that oscillates, so it is called a curved face.

The base circles are the smallest circles that can be drawn with the cam center as a center and touching cam profile, this circle we call the base circle. Therefore, the radius of the base circle, which we call Rb, is called the radius of the base circle.

If there is not enough room to use a larger roller because this pin must be sufficiently large to transmit force between the cam and the follower, and the roller must be at least twice as large as the pin, then the roller requires a lot of space.

Cams exist in many applications, such as dishwashers, sprinklers, etc., but the most famous example is the camshaft in a car. The goal of a cam is to convert rotary motion into linear motion.

There are several types of cam and follower, including cylindrical and plate varieties, each serving specific applications.

This pair of high links are used to move links spontaneously or periodically. However, cam and follower mechanisms are also used by engineers to ensure zero or minimum degree of error, showcasing the precision of these components in various applications.

The base circle is the smallest circle that can be drawn around the cam’s center and still touch the cam profile. It is crucial for defining the cam’s profile and ensuring proper follower movement.

A body with this profile is called a cam. It consists of a fixed link with an inverted pair which is the foundation or fixed link. Cam is the link of revolution. There is a revolute pair between the fixed link and the cam, and the output link is the follower.

When two links are joined either along a line or at a point, it is called a high pair. Two such high pairing mechanisms will be incorporated into the cam-follower system. A high pairing mechanism is known as a cam and follower.

A cam and follower mechanism is a mechanical system that converts rotational motion into linear motion. The cam, which is the driving component, has a specific shape that guides the follower to move in a desired pattern.

If the cam has linear motion, we call it a wedge cam. Wedge cams have a four-link mechanism, the first being a fixed link, the second link being what looks like a cam wedge.

Cam follower bearings, also known as track followers, can come in various designs but are usually made with an extra thick outer ring.

In addition, the mechanism is often used by engineers as a part of the I.C.E.s timing system. In addition, cam-follower mechanisms are used to drive fuel pumps in the automotive industry.

If the input link is called cam also rotates as angular momentum, then cam has rotational or angular momentum, and then we call it as radial cam.

A tracepoint is a point on the follower, which describes the follower movement. For a roller follower, this is the center of the roller.

However, cam and follower mechanisms are also used by engineers to ensure zero or minimum degree of error, showcasing the precision of these components in various applications.

If it is a flat face follower, the tracepoint we use is the point on the face of the follower that is in contact with the cam surface when the follower is at one of the extreme positions; we usually use that extreme—position when follower to nearest cam center.

The cylindrical cam is a cam in which the cylinder is rotated about its axis, and circumferential contours are cut on the surfaces of the cylinder. They are also of two types. In the first type, a groove is cut on the surface of the cam and roller and has a positive oscillating motion.

It depends on the contours of this wedge; as this cam oscillates in the horizontal direction, the follower will oscillate in the vertical direction along with this prismatic pair or this guide.

The location of the center of the roller will produce a curve that is parallel to the cam profile. After kinetic inversion with the cam fixed, it is the location of the tracepoint or roller center.

If it has a slight offset, it means that the axis of translation of the follower does not pass through the cam center, then we call it to offset translation follower.

This design allows cam follower bearings to handle high radial loads while accepting extreme shock loads without the risk of fracturing a softcore part, depending on the application. This pair of high links are used to move links spontaneously or periodically.

Definition, Types, Working Principle and Application Written by Buxin Principle of Machinery In mechanical engineering, engineers often use a high pair link mechanism known as a cam and follower mechanism.

The pressure angle is the angle between the cam surface and the follower’s direction of motion. A lower pressure angle generally results in smoother operation and less friction, while a higher angle may cause increased wear and force on the components.

Key factors include the cam profile, follower type, base circle radius, pressure angle, and the intended application. Proper design ensures efficient motion transfer and minimizes wear and tear.

Chesterton is the world leader in design innovation of split seals. Our innovative split seals have been used to seal thousands of process-critical pieces of rotating equipment with exceptional​​ ​results and many years of leak-free operations.

During the upward movement, the follower does not only have to overcome these two friction forces but to get rid of the spring force.

The smallest circle can be drawn with the cam center as the center and tangent to the pitch curve. This circle has a center on the cam-shaft axis and is tangent to the pitch curve.

As a result, during the upward movements, the pressure angle should be low, & during the return movement, φ can be large, so φmax is more critical during the upward movement.

In the 3rd century, a device known as the cam was produced by Hellenistic water-powered automata. Also, that device was found in the 4th century al-Jazari design.

The 442C uses a mechanism which automatically energizes the seal faces when the gland assembly is installed. During installation, the springs are not energized, minimizing potential installation damage which can occur. Split seal reliability is enhanced!

To define the pitch curve, think of the kinetic inverse. In the kinetic inverse, it is a four-link mechanism, fixed link, cam, roller, and follower. In this four-link mechanism, this link is fixed, but in a kinematic chain, if we fix a kinematic inversion holding cam.

The disc or plate cam is one of the various cam types in which the follower moves radially from the center of rotations of the cam.

The cam rotates as before, but it is the follower due to the shape of the cam, the follower undergoes an oscillating motion, and the follower is hinged at this point. So, it is called an oscillatory follower.

Cam follower bearings, also known as track followers, are specially designed bearings that allow the follower to move smoothly along the cam’s profile. They are built to handle high radial loads and shock loads, ensuring durability and reliability in various applications.

The 442C™ Cartridge Split Seal can be installed without checking for face alignment or touching the sealing elements—the seal faces align themselves and do not have to be handled or worked. The gland assembly is installed around the rotary without inspecting face alignment. Quicker installations and enhanced reliability are the results!

It may touch the surface profile of the cam or may be spring-loaded. It may have a uniform velocity or a uniform acceleration speed. With the help of trailing motion, complex output motion can be obtained.

The follower is hinged to a roller and is in contact with the roller cam; this is called a roller follower. It is the cam that spins, and the follower that is on here oscillates. It is used when a large power has to be transmitted like in stationary IC engines.

The frictional force that would try to oppose this vertical motion would be μ times the normal force. N as normal force, then it will μN.

minimizing installation complications and excessive leakage. As with all split seal options, it offers easy installation and replacement without the need for teardowns.

If space is limited, then we can use a flat face follower if the force involved is not very large as we did in the case of automobiles.

Large Fn is necessary to overcome the frictional force, and the vertical component of Fn will overcome these two frictional forces and the spring force, while during the downward motion, the spring force is helping the followers to come down; hence the contact force Will be less.

Some limitations include potential wear on components, the need for precise alignment, and space constraints. Additionally, certain types of followers, like the knife-edged follower, can have high wear rates and are less commonly used.

If the follower has only a knife-edge with the cam, then we call it a knife-edge follower. The knife-edge is only theoretical as a knife-edge follower is never used due to the very high wear rate. contact stress will be too high.
