Apart from that, varieties of linear motions can be found by utilizing the mechanism. Moreover, due to higher thickness as compared to other bearings Cam follower mechanism can absorb a higher amount of shock that increases the mechanical efficiency of a machine component. Furthermore, the mechanism is entirely versatile that it can be used in a soda machine or also in an aircraft application. Besides, the mechanism is also used in the conveyor belt.
In the case of engines, bearing the load of a camshaft can easily be devised by utilizing the fundamental approach of a crankshaft bearing. Although, flat followers are used by engineers to operate the valves of an engine whereas roller followers are used by engineers in oil and stationary engines. Cam follower mechanism plays a significant role as it utilized to drive a minute machine component seamlessly. Central locks and ordinary lock systems are also developed by incorporating the mechanism of cam and follower.
Various terminologies are integrated with the mechanism that has to be understood by the user of the mechanism. Some of the terminologies are tracepoint, pitch curve, pressure angle and so on. Cam and follower mechanisms are not a small part of mechanical engineering. Therefore, precision and patience are required to implement the mechanism in practice.
At first, the user should aware of the links and pairs before understanding the conception of cam and follower. Cam is a higher pair device thus, the user should grant the degree of freedom to apply the same in a machine component.
Lastly, it can be recommended that the pressure angle should not be increased by the user to restrict the potential impact of side thrust. Saswata Baksi is an Executive editor of Learn Mechanical.

Frictional energy is generated when the stirring tool comes in contact with the workpiece. This results in the generation of heat that is used to create a weld between two workpieces, hence the Blast furnaces were first introduced in China around the 1st century AD. They were further introduced in European countries like Durstel, Germany, Lappyhttan in the 13th century. Due to an Skip to content. Page Contents. Join Us on Telegram. The type of cam follower you should use is dependent on your unique application.
Medical equipment faces a few different challenges when investing in bearings. Find out which factors may impact your bearing selection. Bearing refurbishment may be able to help you save money on replacement parts. Find out if refurbishment is right for your bearings. First, What is a Cam? In these category types of the cam is classified as per the movement of follower. The movement of follower is depending upon the cam profile for this; cams are also classified according to follower movement.
In this type, follower movement is considering. As per name follower movement is done in a way that first dwells then rise again dwell then return and again dwell. This all process is done in one rotation degrees of the cam. 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 degrees of the cam. As per name follower movement is done in a way that first rises then returns. As per name follower movement is done in a way that first dwells then rise then again dwell.
And at degrees it suddenly falls to its first position. 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. 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 all time.
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. A follower is a rotating or oscillating element of a machine that follows the motion of the cam by direct contact. A follower is a mechanical component concerning which, the Cam rotates in an oscillatory or circular motion.
Follower inhibits the push and pulls 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. 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. 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.
The mechanism for Cam and the mechanism for Followers depend upon each other so that the main mechanism of Cam and Followers. The mechanism is essential in the engineering field and has many different functions for the different machines.
There are different types of surface contact between cam and follower and according to surface contact they are classified as follows:. 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 application, because of its sharp edge. This type of follower mainly uses in high-speed operation because it has a smooth contact with the surface. This type of follower has less wear and tear as compared to the other followers. This type of follower looks like a flat surface with an irregular cam.
