Explaining Mechanics on Instagram: "⚙️ Helical gears work thanks to angled teeth cut around the circumference of the gear wheel, allowing a smoother and more gradual engagement than spur gears (straight-cut gears) 🔩✨ Here’s how they operate: 🔹 Angled teeth: The teeth are cut at an angle relative to the gear axis, forming a helical shape. This design allows the teeth to mesh gradually, reducing noise 🔉 and vibrations. 🔹 Continuous contact: Unlike spur gears, where the teeth engage all at once
