Regulatable slider-crank mechanism with satellite gear 2

Pitch diameter of yellow satellite gear = 1/2 Pitch diameter of blue internal gear. Their rolling circles are Cardano ones.

Radius of cranks (pink and yellow) = 1/2 Pitch diameter of the satellite gear.

The green slider's stroke length can be regulated from 0 to 4 times of the crank radius by turning the internal gear via orange worm from 0 to 90 degrees.

The video shows regulating process: blue gear turns from 0 to 30 deg. for medium stroke then from 30 to 90 deg. for max stroke.
