Why Helical Gears Are Widely Used in Commercial Vehicles

Helical gears are extensively utilized in the commercial vehicle sector due to their superior performance and adaptability. Compared to other types of gears, helical gears offer smooth transmission, low noise, and high load-bearing capacity. This makes them the preferred choice for many renowned brands such as ZF, MAN, Volvo, Scania, Dana, Meritor, and Eaton. Additionally, companies like Prior Gear, a leading OEM gear manufacturer, play a crucial role in producing these gears for both OEM and aftermarket applications.

Advantages of Helical Gears

1. Smooth Transmission: The gradual engagement and disengagement of helical gears reduce shocks and vibrations, resulting in smoother operation. This is crucial for heavy-duty applications, ensuring a more pleasant driving experience and improved vehicle longevity.

2. Low Noise: The smoother meshing process of helical gears generates less noise, which is particularly beneficial in commercial vehicles where noise reduction enhances driver comfort and meets regulatory standards.

3. High Load-Bearing Capacity: With a larger contact area between gear teeth, helical gears can handle greater loads. This makes them ideal for heavy-duty trucks, construction machinery, and other demanding applications.

4. Efficient Transmission: Helical gears have higher meshing efficiency, which reduces energy loss and improves fuel economy. This efficiency is especially important for long-haul trucks and commercial vehicles operating over extended distances.
