Input: yellow gear of tooth number Zi = 18.
Output: green teeth-uncompleted gear.
Its tooth number (teeth-completed) Zo = 20
Its number of remained teeth Zoc = 17
Its number of cut-off teeth Zof = Zo — Zoc = 3.
When the input turns 2 revolutions, the output turns 1 revolution and has long dwell (time of 1 input revolution).
The key concept: Zi is less than Zo
Measure to kept the output immobile during its dwell is not shown.
The unusualness for this mechanism is that the input is a tooth completed gear. Not like in ordinary drive: the input is the teeth-uncompleted gear.
