Pink and orange gears are fixed together.
The pink gear and the blue one have revolution joints with green bar.
The orange gear and the violet one have revolution joints with yellow bar. The gears have the same tooth number. The two bars and the orange and pink gear block create a 4-bar linkage. The orange and pink gears are fixed together in such a way that the axis of one gear goes through the pitch circle of the other gear.
Input is the orange gear rotating regularly.
The bars oscillate. The violet and blue gears rotate irregularly and have dwells.
Their motion depends on the 4-bar linkage dimension.
