⚙️ What You’ll Learn
1️⃣ Spur Gear – Simplest gear for transmitting motion between parallel shafts. 2️⃣ Herringbone Gear – Double helical design that ensures smooth, vibration-free motion. 3️⃣ Bevel Gear – Transfers power between intersecting shafts, usually at 90°. 4️⃣ Non-Circular Gear – Converts constant speed into variable motion for custom designs. 5️⃣ Ratchet Mechanism – Allows one-directional motion; used in locks, clocks, and hand tools.
These 3D-printed working models show how mechanical systems convert rotational motion into precision movement.
