Heavy Machinery Double Helical Gear: Precision and Power for Industrial Applications

At FMP Company, we pride ourselves on manufacturing a wide range of these exceptional gears, tailored to meet the demands of heavy-duty industries across Italy—including key hubs like Milan, Venice, Florence, and Bologna—and beyond.

What Are Double Helical Gears?

Double helical gears, often referred to as herringbone gears, are engineered with a distinctive V-shaped design formed by two opposing helical sections. This innovative structure eliminates axial thrust, ensuring smooth and efficient operation without the need for thrust bearings—a key advantage over traditional helical gears. For industries requiring high torque and durability, such as those in Milan’s bustling manufacturing sector or Venice’s marine engineering hubs, double helical gears are an indispensable component in heavy machinery.

Key Advantages of Double Helical Gears

The superior performance of double helical gears stems from their thoughtful design. Here’s why they excel in industrial applications:

Elimination of Axial Load
The symmetrical V-shape cancels out axial thrust, removing the need for additional thrust bearings. This simplifies gearbox designs, reduces maintenance costs, and enhances reliability—perfect for Florence’s precision-driven industries.
High Load Capacity
With wider tooth engagement, these gears distribute loads more effectively, making them ideal for the heavy demands of mining equipment in Bologna or metalworking machinery across Italy.
Increased Efficiency
Continuous tooth contact minimizes vibration and noise, delivering smoother operation and boosting gearbox performance. This efficiency is vital for applications where precision is non-negotiable, such as marine propulsion systems in Venice.
Durability
The balanced design reduces wear and tear, ensuring a long lifespan even in harsh environments. This durability makes double helical gears a cost-effective choice for long-term industrial use, from Milan’s power plants to remote oil fields.
