Description Special features

This mechanism is made of a driving crank and of a driven slider crank. In the considered configuration, the fixed pivot of the driven crank is located on the inside of the circle on which the end of the driving crank moves. This leads to a continuous motion of the slider crank. The configuration where this pivot is located outside the circle on which the end of the driving crank moves is considered in animation I.

The angular speed of the driven crank is variable. The duration of the motion for its part corresponding to the blue arc is shorter than the one related to the red arc. The menu bar includes a zoom (Animation detail) focusing on the mechanism driving and driven cranks.
