S DESIGN AND FABRICATION OF SPHERICAL FACED CAM FOLLOWER PROJECT MEMBERS A. VIJAYARAGAVAN(112) S. VISHNUVARDHAN(113) K. VIVEK(114) ARAVINTH(L 2) PROJECT GUIDE: Mr. D. LOGANATHAN ASST. PROFESSOR

OBJECTIVE �To convert the rotary motion into reciprocating motion easily.

Definition of Cam �A cam is a rotating machine element which gives reciprocating or oscillating motion to another element known as follower. �The cam and the follower have a line contact and constitute a higher pair. �Three elements : �Driver member – CAM �Driven member – Follower �Frame – to support the cam and guide the follower

The type of follower based on the surface contact • KNIFE EDGE FOLLOWER • ROLLER FOLLOWER • FLATFACED FOLLOWER • SPHERICAL FACED FOLLOWER

SPHERICAL FACED FOLLOWER

DEFINITION �If we have spherical shape at follower contacting end, it is called spherical faced follower. This type is considered to be the modification of flat faced follower because in this type , high surface stresses are produced and these stresses are reduced in this type.

APPLICATION • • • Internal combustion engine for operating valve Shoe making machines Sawing machine Punch press Paper cutting machine Fuel pump diesel engine

ADVANTAGES �Surface contact is high compared to other followers. �Efficiency is high.
