When you seek high-precision angular power transmission for space-constrained and heavy-duty systems, YF Gear’s Bevel Gears deliver the perfect balance of compact design, high torque transfer, and quiet operation.
Engineered for automotive differentials, construction machinery steering systems, marine propulsion units, and aerospace landing gear, our gears provide proven durability and precision in the world’s most demanding powertrain environments.
| Gear Type | Design Advantage | Technical Feature | Typical Application |
|---|---|---|---|
| Straight Bevel Gear | Simple design, high torque | 20CrMnTiH alloy steel, HRC60+ surface hardness | Heavy machinery, gearboxes |
| Spiral Bevel Gear | Smooth, quiet, higher contact ratio | 35° helix angle, 50% more contact area, ≤60dB noise | Automotive differentials, robotics |
| Zerol Bevel Gear | No axial thrust, precision meshing | Helix angle ≈ 0°, for low-friction alignment | Instruments, aerospace drives |
These three designs allow engineers to choose the right balance of strength, noise, and precision for each drivetrain project.

Spiral bevel gears have angled curved teeth for smooth and quiet transmission, while zerol bevel gears have near-zero helix angle to eliminate axial thrust, ideal for precision applications.
Torque depends on module, tooth count, and material. We provide load simulation per ISO 6336 and FEA analysis for accurate torque data.
By optimizing helix angle, precision grinding, and applying surface topology correction to minimize meshing vibration.
In many cases yes — bevel gears provide higher efficiency (up to 99%) with similar right-angle transmission, though worm gears are self-locking.
Our spiral bevel gears exceed 100,000 km durability in field tests under alternating load cycles.
Yes, all bevel gears are paired and tested to ensure perfect tooth contact and minimal backlash.
Absolutely. We support 3D scanning, model reconstruction, and sample duplication services.
