1) Description of Helical Gear

Helical gears are usually made of high - quality alloy steels (such as 20CrMnTi, 40Cr) or high - strength cast iron.

Their spiral tooth structures are formed through processes including forging, cutting, and heat treatment.

2) Feature of Helical Gear
a) Surface treatments like carburizing quenching and nitriding can be utilized to increase the hardness of the tooth surface,

thereby enhancing wear resistance and fatigue resistance.
b) Advanced hobbing and gear grinding processes can ensure high - precision tooth profiles, reducing transmission errors.
c) The modular design makes mass production convenient and keeps costs manageable.

​3) Working Principle of Helical Gear

When the tooth surfaces strengthened by heat treatment mesh, the surface hardened layer resists friction and wear,

while the toughness of the core part ensures the overall strength of the gear, achieving efficient and stable transmission.

4) Application of Helical Gear

It is applied in fields with extremely strict requirements for material properties and machining accuracy, such as aero - engine reducers,

construction machinery gearboxes, and precision instrument transmission devices.
