What is rise in cam follower?

What is rise in cam follower?

The follower rise function is defined as the displacement of the follower with change in the cam rotation.

What is the fall of a cam?

The part of the cam profile that causes the cam follower to fall is called the fall. The part of the cam profile that causes the cam follower to remain stationary is called the dwell. The distance between the highest part of the rise and the lowest part of the fall is called the stroke.

What happens to the follower as the cam moves?

A cam and follower mechanism is a profiled shape mounted on a shaft that causes a lever or follower to move. Cams are used to convert rotary to linear (reciprocating) motion. As the cam rotates, the follower rises and falls in a process known as reciprocating motion.

What is motion of the follower when it neither rises or falls?

During a single cam operated sequence, the follower may have periods of rest, or Dwell, when it neither rises nor falls. This would be represented by a horizontal line.

What offset followers?

Offset follower: The center line of the follower does not pass through the center line of the cam shaft. The amount of offset is the distance between these two center lines. The offset causes a reduction of the side thrust present in the roller follower.

What is the maximum value of pressure angle of cam?

–
15° 20°

What is cam rise?

Rise is the motion of the follower away from the cam center, dwell is the motion during which the follower is at rest; and return is the motion of the follower toward the cam center. There are many follower motions that can be used for the rises and the returns.

What is the difference between cam and follower?

Followers move vertically to the axis of the cam when the cam moves in a reciprocating motion. The follower is a part of a machine that follows the cam that is either oscillating or reciprocating in motion. In brief, a driver member is a cam, while a driven member is known as the follower.

How does a knife edge follower work?

Knife edged followers: These are simple in construction. The contacting end of the follower with the cam has a sharp knife edged hence it is called so. The motion between the cam and follower is sliding.

Which is the motion of the follower?

When the cam turns through one motion cycle, the follower executes a series of events consisting of rises, dwells and returns. Rise is the motion of the follower away from the cam center, dwell is the motion during which the follower is at rest; and return is the motion of the follower toward the cam center.
