Input: pink shaft.

Output: grey and blue gears.

The grey gear rotates continuously two times faster than the input. The blue gear rotates interruptedly with the same direction and velocity of the grey gear. When the grey gear makes 2 rev., the blue gear makes 1 rev. and pause during 1 rev. of the grey gear.

For pink gear fixed to the pink shaft: Its number of remained teeth Z1c = 18

Its number of teeth (teeth-completed) Z1 = 40 Its number of cut-off teeth Z1f = Z1 -- Z1c = 22

Orange gear of 40 teeth is fixed to the pink shaft. Tooth number of remained gears: 20

Light green gear is fixed to the green gear shaft.

Yellow gear (for reverse purpose) is in mesh with both light green and blue gears.
