aimed at developing cam-follower systems of all kinds, sizes, and speeds. . simplification in the design and fabrication of assembled cam and follower systems. Cam makes a higher kinematic pair with follower. Cam mechanisms are widely used because with them, different types of motion can be possible. Cams can. Cam-follower systems are frequently used in all kinds of machines. The valves in Compared to linkages, cams are easier to design to give a specific output.
The contacting end of the follower with the cam has a sharp knife edged hence it is called so. The motion between the cam and follower is sliding.
It is not used in practice because small area of contact surface results in high rate of wear at the edges due to which the transmission of motion may not be accurate as desired.
Roller follower: The contact end of the follower is roller and the rolling motion exists between the cam and follower. Compared to knife edge followers, the rate of wear and tear is less due to less friction.
These are used in aircraft engines and oil engines. Flat face or mushroom follower: These are used where space is limited to operate valve of automobile engine. The contact surface is perfectly flat.
The side thrust between guide and follower is much reduced. Journal of Mechanical Design, —, CrossRef Google Scholar 7. Norton, R.
