gearset
A simple planetary, turning
sun in, hold ring, with every member's speed taken from the train's null space and every angular position that speed integrated. The teeth are marked at the pitch points rather than cut as involutes — the flank is the teeth field's subject — but the count is the tooth count and the positions are the solved ones, so what turns and how fast is real. Drag it and watch which way each member goes: sun 1.000 · ring 0.000 · carrier 0.250.
