Ellipse mechanism 3a




Ellipse mechanism with non 90 deg. angle between sliding directions.

The T-conrod and the large gear are fixed together. Position of the green gear center and and the center distance of gear drive must be selected based on the description in

Tooth number of the small gear: 19

Tooth number of the large gear: 38

5 rev. of the small gear corresponds 1 rev. of the green gear.

The strange thing is that the gear drive acts as a planetary gear one but without a carrier. In case the center distance is small, an internal gear drive can be used instead.
