What We Know About Helical Gears
Key Takeaways
Helical gears are one of the most widely used precision transmission components in mechanical engineering. Their teeth are cut at an angle to the axis of rotation, allowing gradual and continuous meshing between gear teeth. This design results in smoother operation, lower noise, and higher load capacity compared with spur gears.
Main Features
●Smooth and quiet transmission: The overlapping contact of helical teeth reduces vibration and noise, making them ideal for high‑speed applications.
●High load‑carrying capacity: Larger contact area improves strength and durability.
●Can transmit power between parallel shafts or crossed shafts.
Common Applications
●Automotive transmissions and differentials
●Electric vehicle reducers
●Industrial gearboxes
●Machinery tools
●Heavy‑duty mechanical equipment
Materials & Heat Treatment
Common materials include alloy steels such as 20CrMnTi, 20CrMo, and 40Cr. Typical heat treatment processes include carburizing, quenching, and tempering to achieve high surface hardness and strong core toughness.
Advantages
●Stable running performance
●High precision and long service life
●Suitable for high‑speed and heavy‑load conditions
●Customizable in module, pressure angle, helix angle, and size
