These changes may be to convert rotary motion to straight line motion or to convert reciprocal (back and forth) motion to intermittent motion. They may also transform a fixed type of motion, for example by magnifying a linear motion or by slowing down a rotary motion.
LearningReviews note: The six basic types of motions and mechanisms described and illustrated are linear, rotary, intermittent, reciprocating, oscillation and irregular motion. For a fee, you can also purchase a downloadable version illustrating more complex mechanisms.
