High-Performance Gearbox Bevel Gear for Industrial Power Transmission
1. Product Overview
Our precision-engineered gearbox bevel gear is designed for high-torque, right-angle power transmission in demanding industrial applications. Manufactured from case-hardened alloy steel with CNC-machined spiral or straight tooth profiles, this gearbox bevel gear ensures minimal backlash, high load capacity, and long service life. Whether you need to change rotational direction, reduce speed, or increase torque, our bevel gear sets provide reliable performance in compact form factors suitable for heavy machinery, material handling, and automation systems.
2. Key Features
- Case-Hardened Alloy Steel: Surface hardness of 58-62 HRC ensures excellent wear resistance and fatigue strength.
- Spiral & Straight Tooth Options: Spiral bevel gears offer smoother, quieter operation at high speeds; straight bevel gears provide cost-effective solutions for lower RPM applications.
- High Torque Density: Optimized tooth geometry allows for compact gearbox designs without sacrificing load capacity.
- Low Backlash (<3 arcmin): Precision grinding and lapping processes ensure accurate motion control for servo-driven systems.
- Corrosion Resistance: Optional anti-corrosion coating for harsh environments (marine, chemical processing).
- Interchangeable Mounting: Standard flange and shaft configurations compatible with major gearbox brands.

7. FAQ
Q: What is the difference between spiral and straight bevel gears for a gearbox?
Spiral bevel gears have curved teeth that engage gradually, reducing vibration and noise. They are ideal for high-speed applications (>1,500 RPM) and applications requiring smooth torque transfer. Straight bevel gears have straight teeth that engage suddenly, making them more cost-effective for low-speed, high-torque applications where noise is less critical.
Q: Can you match existing gearbox bevel gears from other manufacturers?
Yes. We offer reverse engineering services. Send us your worn gear sample or 3D scan, and we will replicate the geometry with improved materials and heat treatment. We can also adjust the backlash or ratio to optimize performance for your specific operating conditions.
Q: What lubrication is recommended for these bevel gears?
We recommend ISO VG 220-460 extreme pressure (EP) gear oils for most industrial applications. For high-speed spiral bevel gears (above 3,000 RPM), synthetic PAO-based oils with anti-foaming additives are preferred. Our technical team can provide a detailed lubrication schedule based on your duty cycle and ambient temperature.
Q: How do I select the correct gearbox bevel gear size for my motor?
Key factors include: input torque (Nm), required output speed (RPM), duty cycle (continuous vs. intermittent), and mounting orientation. As a rule of thumb, the gear's pitch diameter should be at least 3 times the shaft diameter. Contact our engineering team with your motor specifications and we will calculate the optimal module, tooth count, and face width for your application.
Q: What is the typical lifespan of your bevel gears?
Under proper lubrication and within rated load conditions, our case-hardened gearbox bevel gears typically achieve 10,000-20,000 operating hours before requiring replacement. Factors such as shock loads, contamination, and temperature extremes can reduce this lifespan. We recommend annual oil analysis and visual inspection to maximize service life.
