a) Follower to move outwards through an angular displacement of 20° during 120° of cam rota- tion. b) Follower to dwell for 50° of cam rotation. c) Follower to return to its initial position in 90° of cam rotation with uniform acceleration and retardation. d) Follower to dwell for the remaining period of cam rotation. The distance between the pivot centre and the roller centre is 130 mm and the distance between the pivot centre and cam axis is 150 mm. The minimum radius of the cam is 80 mm and the diameter of the roller is 50 mm.

Question
Transcribed Image Text:Draw the profile of a cam with oscillating roller follower for the following motion :
(a) Follower to move outwards through an angular displacement of 20° during 120° of cam rota-
tion.
(b) Follower to dwell for 50° of cam rotation.
(c) Follower to return to its initial position in 90° of cam rotation with uniform acceleration and
retardation.
(d) Follower to dwell for the remaining period of cam rotation.
The distance between the pivot centre and the roller centre is 130 mm and the distance between
the pivot centre and cam axis is 150 mm. The minimum radius of the cam is 80 mm and the
diameter of the roller is 50 mm.
