Precision Herringbone (Double Helical) Gears
Product Description
Yile Machinery is a specialist manufacturer of custom-engineered herringbone gears, also known as double helical gears. Designed for the most demanding power transmission systems, our herringbone gears deliver superior performance, exceptional strength, and smooth, quiet operation by completely eliminating axial thrust.
The Herringbone Advantage: Maximum Power, Zero Thrust
The unique V-shaped tooth structure of a herringbone gear offers significant advantages over other gear types, making it the ideal choice for high-torque, heavy-duty machinery.
Zero Axial Thrust: The opposing right-hand and left-hand helices cancel out thrust forces internally. This allows for simpler, more robust bearing arrangements and prevents load transfer to other components in the gearbox.
Higher Torque Capacity: With no axial force limitations, herringbone gears can transmit greater power than a comparably sized single helical gear.
Smooth and Quiet Operation: The continuous engagement of the V-shaped teeth ensures a gradual, smooth transfer of load, minimizing vibration and noise even at high speeds.
Manufacturing Excellence for Heavy-Duty Performance
Producing a flawless herringbone gear requires advanced machinery and process control. Our manufacturing process is optimized for reliability and precision.
Material Selection & Forging: We start with high-grade forged alloy steels such as 42CrMo (AISI 4140) , 34CrNiMo6, or other customer-specified materials. Forging ensures a dense, homogenous grain structure for maximum impact and fatigue resistance.
Precision CNC Machining: The forged blank is precision machined to establish all critical dimensions before gear cutting.
Advanced Gear Cutting: We utilize specialized CNC Gear Hobbing or Shaping machines to accurately generate the complex double helical tooth profile.
Targeted Heat Treatment: Gears undergo a controlled heat treatment process (e.g., quenching and tempering, carburizing, or nitriding) to achieve the precise surface hardness and core toughness required for long service life.
Optional Precision Grinding: For the highest level of accuracy and surface finish, we offer CNC gear grinding after heat treatment to produce a perfect tooth profile for optimal contact and efficiency.
