High Precision Wear Resistant Transmission Gear for Long Service Life in Heavy-Duty Applications

High-Quality Transmission Gear – Improve Gearbox Performance

The industrial gearbox gear is designed for heavy-duty applications in metallurgy, mining, chemical plants, and energy systems. Made from premium alloy steel with advanced carburizing and grinding processes, the gear ensures high precision, wear resistance, and long service life. With optimized tooth design, each reduction gear guarantees smooth and efficient torque transmission, even under continuous heavy loads. Choosing our gear for an industrial gearbox means choosing reliability and efficiency.

Key Features 

• Helical tooth profile: Larger contact area, smooth meshing, and lower noise.

• Gear pair design: Efficient torque transmission within compact space.

• Balanced axial force: Extends the service life of both gears and bearings.

Materials and Heat Treatment

From an engineering perspective, material selection and heat treatment processes define gear performance:

• Materials: Premium alloy steels such as 20CrMnTi and 18CrNiMo7-6.

• Heat Treatment: Carburizing and quenching → surface hardness HRC 58–62 with a tough core.

• Gear Grinding: Tooth surface roughness Ra0.8–Ra0.4 ensures precise and smooth meshing.

Accuracy and Standards

Industrial gearbox gears are manufactured according to international standards:

• Precision Grade: DIN 6–8 / AGMA 10–12.

• Inspection Items: Tooth profile error, lead error, backlash, contact pattern.

• Quality Control: 3D coordinate measurement, gear testing machine, and metallographic analysis.

This guarantees stable and reliable transmission under high-speed and heavy-load conditions.

 Performance Advantages

• High transmission efficiency (≥95%).

• Low noise and vibration, ideal for automation and precision machinery.

• Strong load-bearing capacity, suitable for continuous heavy-duty operations.

• Extended service life, often tens of thousands of operating hours with proper lubrication.
