    "data": {
        "note": "Worm-drive efficiency (worm driving the wheel) = tan(lead angle) ÷ tan(lead angle + friction angle), where the friction angle = atan(μ). It is low for the small lead angles that give big ratios — often 50–70 % — which is why worm gears run warm and need good lubrication; multi-start, high-lead worms reach 90 %+. When the lead angle ≤ the friction angle the back-driving efficiency goes to zero: the drive is self-locking.",
