A Swashplate may be regarded as a simple form of cylindrical cam.
Features and Applications
Properly machined cylindrical cams, as used in engine gearboxes for example, may have slots milled into the side of the cylinder such that the follower is positively driven each way and does not rely on a spring for its return.
|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.|
