Study of planetary worm-worm drive 1b




Input: blue crank.

Internal gear (tooth number Z2 = 76) is stationary. Yello worm (lead = t1 is fixed to the yellow gear (tooth number Z1 = 16). Block of yellow worm and gear rotates idly on eccentric shaft of the blue crank. The yellow worm can roll on the pink large worm thus reduces the friction.

Output: pink worm (lead = t2 = 2.t1) moving linearly an amount of S in 1 revolution of the input.

S = t2+(Z2/Z1)*t1
