The cam follower must rise outward 13 mm with constant velocity in 3 s, dwell for 3 s, fall 5 mm with constant accelera- tion in 2 s, dwell for 3 s, fall 8 mm with constant S, acceleration in 2 s, and then repeat the sequence. Determine the required speed of the cam and graphically plot a follower displacement diagram.

A cam drives a flat reciprocating follower in the following manner. During the first 90° rotation of the cam, the follower moves outward through a distance of 30 mm with SHM. The follower dwells during next 90° cam rotation. During the next 90° cam rotation, the follower moves inward with SHM. The follower then dwells next 90° cam rotation. Draw the cam profile and calculate the maximum values of velocity and acceleration when cam rotates at 10 rad/s.

WERABE UNIVERSITY COLLEGE OF ENGINEERING AND TECHNOLOGY DEPARTMENT OF MECHANICAL ENGINEERING Mechanism of Machinery - Assignment - 02 A cam rotating clockwise at a uniform speed of 200 r.p.m. is required to move an offset roller follower with a uniform and equal acceleration and retardation on both the outward and return strokes. The angle of ascent, the angle of dwell (between ascent and descent) and the angle of descent is 120°, 60° and 90° respectively. The follower dwells for the rest of cam rotation. The least radius of the cam is 50 mm, the lift of the follower is 25 mm and the diameter of the roller is 10mm. Draw the cam profile A. When the line of action of follower passes through the centre of the cam and B. The line of stroke of the follower is offset by 20 mm from the axis of the cam. 2.) A flat faced reciprocating follower has the following motion: i. The follower moves out for 80° of cam rotation with uniform acceleration and retardation, the acceleration being twice the…
