Study of planetary worm-worm drive 1a

Input: blue crank.

Internal gear (tooth number Z2 = 76) is stationary. Orange worm of circular grooves is fixed to the orange gear (tooth number Z1 = 16). Block of orange worm and gear rotates idly on eccentric shaft of the blue crank. The orange worm can roll on the pink large worm thus reduces the friction.

Output: pink worm (lead = t2) moving linearly an amount of t2 in 1 revolution of the input.
