A simulation of a planetary gear mechanism where one gear is fixed (the sun gear) and another the planet gear) rotates around the periphery. The path of points on the planet gear generate epicycloid curves. In this model two links of a four bar linkage are coupled in a sun-planet motion. This is an abstract model where pedestal and supports have been removed, leaving only the moving links and their constraints. Click and drag any of the ungrounded joints.
