QUESTION 2; LOCI (CAM)

Given:
The detail of a wedge-shaped follower and the
camshaft

Specifications:

The follower reciprocates on the horizontal
centre line of the camshaft

© The minimum distance from the follower to the
centre of the camshaft = 14 mm

* Rotation = clockwise

Motion:

The cam imparts the following motion to the

follower:

elt moves left with uniform acceleration and
retardation for 40 mm over the first 180°

elt moves further left with uniform motion for
15 mm over the next 90°

elt moves right with simple harmonic motion
back to the original position for the rest of the
rotation.

Instructions:

* Draw, to scale 1: 1, the given camshaft and
the wedge-shaped follower at the minimum
distance.

«Draw, to a rotational scale of 30° = 8 mm and
a displacement scale of 1: 1, the complete
displacement graph for the required motion.

* Label the displacement graph and include the
scale.

Project and draw the cam profile from the
displacement graph.

Show the direction of rotation on the cam
profile
