    1. This reminds of an aerobatic maneuver. A full circle while rolling opposite direction.
      Ex; turn right, roll left.

      BTW: gears as shown was used beginning nigh 200 yrs ago to turn rotary motion into rectilinear motion.

  3. I saw one with a square center gear inside a circular piece of stock rotating around it, and the whole thing would fit easily between thumb and forefinger.

    From November '20.

    1. Nein. This and similar gearing was in widespread use well before herr Wankel's birth.

      In fact, the period beginning the late 1700s/early 1800s until maybe mid-century, featured all sorts of take offs on gear combinations and gear shapes.

      Some machinists created geometric gears to, say turn rotary to rectilinear to rotary just because they could. It was a wild period for machine works. Rube Goldberg didn't pop out of nowhere.

    2. I saw an old film compilation of weird gears from yesteryear on YouTube. Wish I'd saved it.
