Introduction: Cam Analysis Machine is a motorized unit consisting of a camshaft driven by a D.C. motor .The shaft runs in a double ball bearing. At the free end of the cam shaft a cam can be easily mounted. The follower is properly guided in gunmetal bushes and can be changed to suit the cam under test. A protractor scale is fitted coaxial with the shaft. Dial gauge is provided to note the follower displacement for the angle of cam rotation. A spring is used to provide controlling force to the follower system. Weights on the push rod can be adjusted as per the requirement. 2 amp closed type D.C. dimmer is provided for the speed regulation.


Description: The apparatus is designed to study the cam profiles and performance of cam and follower

system. The apparatus consists of a shaft supported by ball bearings upon which three different types of cams be mounted. The push rod for follower is supported vertically, which can adopt three different types of followers. Cams and followers can be changed easily. A variable speed motor rotates the cam. A dial gauge permits plotting of follower displacement with respect to cam position. By operating the system at different Speeds, jump speed can be found and also the effect of weight and spring force on jump speed can be studied. Jump can be visualized also with the help of an optional stroboscope.
