Barrel, Cylindrical, and Globoidal Cams are types of 3D-Cams that you can model and design in MechDesigner.

The Cam usually rotates at constant speed. However, this is not necessary. For example, the Cam can be stationary.

You can save the 3D-Cam to a STEP file-type, or export the surface data to SolidWorks, or save the surface data as XYZ coordinates.

6C1: Barrel-Cam : Oscillating

It is possible to design Barrel-Cams with:

•Follower-Rollers that move along grooves that are cut into the wall of the Barrel (see image)

To model a Groove Barrel-Cam you need a minimum of one Follower-Roller.

AND

•Follower-Rollers that move along the sides of a rib that extends out from the wall of the Barrel.

To model a Rib Barrel-Cam, you need to a minimum of two Follower-Rollers.

6C2: Globoidal-Cam : indexing

These cams are also called Ferguson Drives, or Roller Gear Drives.

6C3: Examine 3D-Cams for Follower Clearance.
