FAQ

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.

What is an end cam?
End cam (Figure 6-5b): This cam has a rotating portion of a cylinder. The follower translates or oscillates, whereas the cam usually rotates. The end cam is rarely used because of the cost and the difficulty in cutting its contour.

What is a spiral cam?
A spiral cam is a face cam in which a groove is cut in the form of spiral. The spiral groove consists of teeth which mesh with a pin gear follower. The velocity of the follower is proportional to the radial distance of the groove from the axis of the cam.

What is Globoidal cam?
Globoidal cams are spatial (3D) cams. Input and output in globoidal cam gears rotate, and the axes of rotation of cam and follower are perpendicular to each other. The special feature of globoidal cams is that the roller axis is located in the plane of movement of the rotating follower.

How does a heart shaped cam work?
HEART SHAPED CAMS: This cam causes the follower to move with a uniform velocity. Heart-shaped cams are essential when the follower motion needs to be uniform or steady as, for example, in the mechanism that winds thread evenly on the bobbin of a sewing machine.

Why are cams different shapes?
Cams can be shaped in any number of ways and this is determined by the way the follower is to move. The shape of the cam is called the PROFILE. Examples of various cam profiles can be seen below.

Where is a barrel cam used?
Barrel Cam with milled grooves is used in sewing machines to guide thread. Facial Cam – double ended to increase follower stroke without changing the pressure angle. Gravity maintains contact between rollers and cam.

What are the 4 main types of cam?

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

What is a radial cam?
Radial Cams are one of the most common types of ‘cam’. The ‘radial cam’ is a rotating plate or disc with an outer circumference shaped to produce a required movement (usually linear) to a ‘follower’ which is held against it.

How do I create a cam and follower?
Design of the Cam Profile The radius of the outermost circle is equal to the base circle radius plus the lift of the cam. Since, there is no offset of the follower; hence the cam will be aligned with AB. Now divide the base circle and the outermost circle by 300 sectors. So, there will be total of 12 sectors.
