What Are The Different Types Of CAM?

What is cam profile?

[′kam ‚prō‚fīl] (design engineering) The shape of the contoured cam surface by means of which motion is communicated to the follower.

Also known as pitch line..

How are cam followers classified?

Classification of Cams The follower moves in a plane perpendicular to the axis of rotation of the camshaft and is held in contact with the cam by springs or gravity. a)Cylindrical cam (Fig. 4.2): The cylindrical cam has a groove cut along its cylindrical surface.

What is a knife edge follower?

[′nīf ‚ej ′kam ‚fäl·ə·wər] (design engineering) A cam follower having a sharp narrow edge or point like that of a knife; useful in developing cam profile relationships.

What are the three types of CAM?

CamsCircular. Circular cams use an off-centre pivot to cause the follower to move up and down. … Pear. Pear cams are called this as they have the shape of a pear. … Snail or drop. Snail or drop cams have the appearance of a snail shell. … Heart-shaped or constant velocity.

What is radial cam?

A radial cam converts a rotational motion into a translational motion of the follower. … This Demonstration generates a cam profile starting from a displacement diagram defined by a set of locators. The first, second, and third derivatives of the follower’s displacement (velocity, acceleration, and jerk) are plotted.

What is a snail drop cam?

A Snail Cam (aka Drop Cam), so-called because of the snail-like appearance, has a slow rise and then a sudden drop. This is a one-event-per-turn cam with a slow build-up to the peak and a rapidly decreasing edge.

What is wedge cam?

Wedge cam: A wedge cam has a wedge of specified contour. The translation motion of the wedge is imparted to the follower which either reciprocates or oscillates. Generally, a spring is used to maintain contact between the follower and the cam.

What are cam and followers used for?

The cam and follower mechanism is widely used for operating the inlet and exhaust valves of internal combustion engines. They are used in wall clocks and the feed mechanism of automatic lathe machines. They are also used in paper cutting machines and weaving textile machinery.

What is a cam mechanism?

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 difference between radial and cylindrical cam?

In the most common type, the follower rides in a groove cut into the surface of a cylinder. … Cylindrical cams may also be used to reference an output to two inputs, where one input is the rotation of the cylinder and the other is the position of the follower along the cam. The output is radial to the cylinder.

What is the function of CAM?

A cam is a reciprocating, oscillating or rotating body which imparts reciprocating or oscillating motion to a second body, called the follower, with which it is in contact. The shape of the cam depends upon its own motion, the required motion of the follower and the shape of the contact face of the follower.

What is a cam displacement diagram?

A Displacement Diagram is essentially a graph which plots the movement of a cam follower against time. Since the cam’s movement is usually constant then equal time intervals can be represented by equal distances along the horizontal axis and the resulting follower movement (or ‘displacement’) along the vertical axis.

What is CAM and its types?

A cam is a rotating element that gives oscillating or reciprocating motion to the follower which is another element of this machine by direct contact. This part is mainly used to transform the motion from rotary into linear to another part.

What is dwell period in Cam?

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 a cylindrical cam?

A cylindrical cam is a 3D cam which drives its follower in a groove cut on the periphery of a cylinder. The follower, which is either cylindrical or conical, may translate or oscillate. The cam rotates about its longitudinal axis, and transmits a translation or oscillation displacement to the follower at the same time.
