Gear Rack Drive

grabcad

A simple reciprocating mechanism, using a rack and gear and being driven by an eccentric shaft. This contruction makes the movement asymmetric. During the first 30% of the time, the output moves forward 56 degrees and returns to original position. Then, during the other 70%, moves backward 150 degrees and returns to the initial position. In both directions, maximum speed is the same. See the plots.
