1. welcome

2. Aim : seminar on any topic of 4 th semester Name: hadolikar s.l Branch: ME Ro.no.1027

3. Subject: theory of machines Topic : cam & followers

4. Concept & definition of cam followers A cam is rotating a machine element which gives reciprocating or oscillating motion to the another element know as follower. The cam & follower has a point or line contact constitute a higher pair.

5. classification of foollowers According to surface contact 1 . Knife edged follower

6. roller follower

7. flate face follower

8. spherical follower

9. ossciating or rotary follower According to motion of the follower

10. According to the path of motion of the followers Offset follower

11. classification of cam 1 radial cam 2 cylindrical cam 3 wedge cam

12. Cylindrical cam

13. Wedge cam

14. box cam

15. App. of cam & follower 1 .The most well known use of cams is in car engines. The Cam operated valve system can be found in modern car engines and incorporates a number of cams; the valves are opened by cams, four- and six-lobed cams govern the spark distribution and many car petrol oil pumps are cam driven.

16. 2 . These are used in wall clock 3 . These are used in feed mechanism In automatic lathe machine 4. These are used in paper cutting machine. 5 . It is use in textile machine

23. simple harmonic motion

24. uniform acceleration & retardation

26. Given data: out stroke of follower (s)=60mm Minimum radius of the cam =50mm diameter of the cam shaft = 35mm Angle of outstroke=180 angle of return stroke=180

27. thank you
