cam is to give the following motion to a knife-edged follower: Outstroke during 75° of cam rotation; 2. Dwell for the next 60° of cam rotation; Return stroke during the next 80° of cam rotation, and 4. Dwell for the maining 145° of cam rotation. The stroke of the follower is 30 mm and the inimum radius of the cam is 40 mm. The follower moves with uniform velocity iring both the outstroke and return strokes. Draw the profile of the cam when ) the axis of the follower passes through the axis of the camshaft, and (b) the is of the follower is offset by 25 mm from the axis of the camshaft. Determine e maximum velocity and acceleration of the follower during its ascent and escent, if the cam rotates at 250 r.p.m. Draw the displacement, velocity and celeration diagrams for one complete revolution of the cam

Question
Transcribed Image Text:A cam is to give the following motion to a knife-edged follower:
1. Outstroke during 75° of cam rotation; 2. Dwell for the next 60° of cam rotation;
3. Return stroke during the next 80° of cam rotation, and 4. Dwell for the
remaining 145° of cam rotation. The stroke of the follower is 30 mm and the
minimum radius of the cam is 40 mm. The follower moves with uniform velocity
during both the outstroke and return strokes. Draw the profile of the cam when
(a) the axis of the follower passes through the axis of the camshaft, and (b) the
axis of the follower is offset by 25 mm from the axis of the camshaft. Determine
the maximum velocity and acceleration of the follower during its ascent and
descent, if the cam rotates at 250 r.p.m. Draw the displacement, velocity and
acceleration diagrams for one complete revolution of the cam
