    Cams can be circular, pear shaped, or irregular. Cams and cam followers are very prone to wear due to friction. Cam followers often have tiny rollers attached to them to reduce this friction. Common applications with cam mechanisms include an electric toothbrush, an engine camshaft, and clamps. This book provides a logical sequence of steps for the derivation of the relevant equations from first principles, for the more widely used cam mechanisms. Although originally derived for use in high performance engines, this work is equally applicable to the design of mass produced automotive and other internal combustion engines.

    However, cams go beyond the function of linkage mechanisms, allowing a tremendous range of possibilities for the output motion. Depending on the application, the follower may be required to. The cam itself is the small mechanical part that looks like a guitar pick or a tear drop. Devices that utilize cams to transform one type of motion into another are typically composed of three main parts: the cam, the shaft (or rotating wheel), and the lever (also called a .

    6. Classification of Cam mechanisms Cam mechanisms can be classified according to motion restrictions: CEP: Critical extreme position. Only define start and stop position of the follower. CPM: Critical path motion. Path and/or one or more of its derivates are carefully specified. Cams can be classified according to their motion program. Early S-shaped cams were derived from an Archimedean spiral form of locus which gives a constant rate of lift per degree of cam rotation, but varying cam radius. The present tendency is for the S cam to be generated from an involute spiral (Fig. (a)) which gives a slight reduction in lift per degree of cam rotation, but maintains a constant cam effective radius so that the shoe tip force.

This book contains alot of very good technical reference for the design of cams. A strong grasp of calculus is necessary to make this reference worth while (not for the mathematically weak). Most focus is upon radial style cams.

The reason why the cam mechanism is so widely used is that the cam mechanism can realize various complicated motion requirements, and the structure is simple and compact. Common materials. 45, 40Cr, 9sicr, 40crMo. Working Principle. • Explain what a cam is, how it is used, and the typical types of cams • Identify force closed and form closed followers and explain the benefits and limitations of each • Describe the primary types of cam motion programs Introduction to Cam Design Source: Norton, Design of Machinery.

Cams are found in almost all types of machines e.g. textile, printing, glass-making, milling, forming, packaging, transporting, and agricultural. Up-to-date requirements on the performance of such machinery necessitate the use of efficient methods for the design and production of high speed cam-follower assemblies.

Rapid advances in computing devices and numerically controlled machine tools. Cams are classified according to the direction of displacement of the follower with respect to the axis or oscillation of the cam. The two most important types are: Disc or Radial Cams In these the working surface of the cam is shaped that the reciprocation or oscillation of the follower is in a plane at right angles to the axis of the cam.

Synthesis of cam mechanisms used for the exact design of cam profile for desired movement program of follower is presented. This method uses continues trajectory conditions in the points where Author: Ahmet Shala. Cams are machine elements whose function is to control lateral movement through its rotational displacement.

One application is the control of valve positions (they control inlet of air-fuel mixture as well as outlet of the exhaust gases e.g CO,CO2 & H2O). They are shaped to be eccentric, so that the axis of rotation is slightly offset, and to enable a follower to trace out the path that the.

Cam mechanisms are widely used because with them, different types of motion can be possible. Cams can provide unusual and irregular motions that may be impossible with the other types of mechanisms.

However, the manufacturing of cams is expensive and the wear effect due to the contact stresses is a disadvantage. Cam makes a higher kinematic pair with follower. Cam mechanisms are widely used because with them, different types of motion can be possible.
