High-Performance Bevel Gear Wheel for Precision Power Transmission
1. Product Overview
In the realm of mechanical power transmission, the bevel gear wheel stands as a critical component for changing rotational direction between intersecting shafts. Our premium-grade bevel gear wheels are engineered to deliver exceptional torque transfer, minimal backlash, and extended service life in demanding industrial environments. Manufactured from case-hardened alloy steel (20CrMnTi/8620) and precision-ground to AGMA Class 10-12 tolerances, these gears ensure smooth, quiet operation even under high-speed or high-load conditions.
Whether you require a straight, spiral, or hypoid configuration, our bevel gear wheels are designed to optimize efficiency in applications ranging from automotive differentials to heavy-duty conveyor systems. Each unit undergoes 100% dimensional inspection and magnetic particle testing to guarantee reliability.
2. Key Features
- High-Strength Material: Forged from 20CrMnTi alloy steel with carburizing and quenching heat treatment (HRC 58-62 surface hardness).
- Precision Tooth Profile: CNC-ground teeth with tooth flank roughness Ra ≤ 0.8 μm for reduced friction and noise.
- Interchangeable Design: Standardized pitch angles and mounting dimensions compatible with major OEM systems.
- Enhanced Durability: Shot-peened root fillets increase fatigue strength by up to 30%.
- Corrosion Resistance: Optional manganese phosphate or black oxide coating for harsh environments.
- Custom Configurations: Available in straight, spiral, Zerol, and hypoid tooth forms with custom bore/keyway specifications.

4. Application Scenarios
The bevel gear wheel excels in any application requiring a 90-degree power transfer with high efficiency. Key industries include:
- Automotive & Off-Highway: Differential gears, transfer cases, PTO drives.
- Industrial Machinery: Conveyor drives, mixers, crushers, and packaging equipment.
- Aerospace & Defense: Actuation systems, helicopter transmissions, radar positioning.
- Marine: Stern drives, thrusters, winch systems.
- Renewable Energy: Wind turbine pitch and yaw drives, solar tracker gearboxes.
5. Advantages
- Higher Efficiency: Spiral bevel gear wheels achieve up to 98% efficiency due to gradual tooth engagement, reducing heat generation.
- Reduced Noise: Helical overlap in spiral designs ensures smoother meshing—ideal for noise-sensitive environments.
- Compact Design: Compared to worm gears, bevel gear wheels offer higher torque density in a smaller footprint.
- Backward Compatibility: Our mounting dimensions (pilot diameter, bolt pattern) match Gleason, Klingelnberg, and Oerlikon standards.
- Cost-Effective: Near-net-shape forging minimizes material waste, and our in-house heat treatment reduces lead times.

7. FAQ
Q1: What is the difference between straight and spiral bevel gear wheels?
A1: Straight bevel gear wheels have teeth parallel to the cone axis—simple to manufacture but generate more noise and vibration. Spiral bevel gear wheels have curved teeth that engage gradually, offering smoother operation, higher load capacity, and lower noise, making them preferred for high-speed or precision applications.
Q2: Can you match an existing bevel gear wheel for replacement?
A2: Yes. Provide us with the original gear’s tooth count, module, pitch angle, bore diameter, and mounting pattern. We can reverse-engineer and produce an exact match, often with improved material or heat treatment.
Q3: What lubrication is recommended for your bevel gear wheels?
A3: For standard applications, use EP (extreme pressure) gear oil ISO VG 220–460. For high-speed or high-temperature environments, synthetic PAO or PAG oils are recommended. We provide a detailed lubrication guide with every order.
Q4: What is the typical lead time for custom bevel gear wheels?
A4: Standard custom orders (module 2–10, up to 300 mm diameter) ship within 4–6 weeks. Rush orders with expedited heat treatment and inspection can be completed in 2–3 weeks.
Q5: How do you ensure the bevel gear wheel mates correctly with its counterpart?
A5: We supply gear sets as matched pairs when required. Each pair is lapped together and tested for tooth contact pattern, backlash, and running noise before shipment. Single gears are manufactured to strict master gear standards.
Q6: Do you offer prototypes or small batch production?
A6: Absolutely. We support low-volume runs of 5–50 pieces for prototyping, maintenance, or niche machinery. Our flexible production line accommodates both small batches and high-volume mass production.
