Custom Bevel Gear Machining & OEM Manufacturing
Hansheng Automation delivers high-precision custom metal bevel gears engineered for industrial automation, robotics, packaging machinery, and power transmission systems. With over 10 years of manufacturing expertise, we provide end-to-end OEM gear solutions-from rapid prototyping to full-scale production.
Key Manufacturing Capabilities & Features
Complete Tooth Profile Options
Precision machining for all four major bevel gear types-Straight, Spiral, Hypoid, and Zerol.
Premium Industrial Materials & Heat Treatment
Machined from high-grade carbon steel (S45C/C45), alloy steel (20CrMnTi, 42CrMo), stainless steel, and non-ferrous metals. Optional carburizing and quenching (up to 62 HRC) ensure superior wear resistance under high transmission loads.
Full OEM Customization (From Drawing or Spec)
Custom production according to your 2D/3D CAD drawings (STEP, IGS, DWG) or parameter specifications. Flexible options for pitch/module (0.5–5.0), tip diameters (3 mm–300 mm), keyway dimensions, bore types, and surface coatings (black oxide, zinc plating, anodizing).
Technical Specifications & Capability Limits
Basic Selection Parameters
| Parameter | Capability |
|---|---|
| Module Range | M 0.5 – 5.0 (custom pitches available on request) |
| Max. Outer Diameter | Up to 300 mm (≤250 mm for high‑volume grinding) |
| Gear Ratio Range | 1:1 to 1:6 (speed reduction or increasing) |
| Tooth Profiles | Spiral Bevel, Straight Bevel, Hypoid Bevel, Zerol Bevel |
Machining Accuracy
- Ground teeth: ISO 5–7 (AGMA 12–11)
- Milled / hard‑scut teeth: ISO 8–10 (AGMA 10–9)
- Fully compliant with DIN 3962 / AGMA 2015.
Surface Finish
- Ground: Ra 0.8 – 1.2 μm
- Milled: Ra 1.6 – 3.2 μm
- Surface roughness is strictly matched to the chosen accuracy grade.
Backlash Control
Calculated dynamically per DIN 3967 / AGMA 2003, based on actual module, pitch diameter, and operating conditions.
Typical reference range: 0.02 – 0.15 mm – but we offer customised backlash (including asymmetric designs) to accommodate thermal expansion, high speed, or heavy‑load applications.
Materials & Process Chain
Material Options
| Category | Grades |
|---|---|
| Carbon Steel | S45C, C45, AISI 1045 |
| Alloy Steel | 20CrMnTi, 42CrMo, 8620, 20CrNiMo |
| Stainless Steel | SUS304, SUS316, SUS420, SUS440C |
| Non‑Ferrous | Brass (C36000), Bronze, Aluminium (7075 / 6061) |
Heat Treatment & Secondary Processes
Pre‑treatment
Quenching + high‑temperature tempering (to obtain a uniform microstructure for final machining).
Case Hardening
Carburising & quenching (58–62 HRC) / Induction hardening (45–55 HRC) / Nitriding.
Surface Protection & Strengthening
Manganese phosphating, black oxide, shot peening (for root fillet fatigue resistance) – Zinc plating is not recommended on precision tooth flanks due to hydrogen embrittlement and uneven coating thickness.
Secondary Machining
Keyways (DIN 6885), set‑screw holes, spline bores, integrated shafts, custom hubs.
Quality Assurance
Every custom bevel gear order at Hansheng undergoes the following quality control steps before shipment:
- CMM Dimensional Inspection
- Gear Mesh Testing
- Runout Inspection
- Hardness Testing
- Visual and Surface Inspection
How to Select Bevel Gear: Choosing the Right Profile for Your Application
Not sure which bevel gear tooth profile fits your system? Each profile offers distinct advantages in torque capacity, operational noise, and shaft configuration. The following is a comparison table compiled by Hansheng based on available data. It may contain errors and is for reference only.
| Feature / Criteria | Straight Bevel Gear | Spiral Bevel Gear | Hypoid Bevel Gear | Zerol Bevel Gear |
|---|---|---|---|---|
| Tooth Geometry | Straight teeth, intersecting shafts | Curved / Helical teeth, intersecting shafts | Curved teeth, offset (non-intersecting) shafts | Curved teeth with zero spiral angle (intersecting) |
| Operating Noise Level | Moderate to High | Low (Quiet operation) | Very Low (Ultra-quiet) | Low to Moderate |
| Max Pitch Line Speed | Up to 5 m/s | Up to 30+ m/s | Up to 30+ m/s | Up to 15 m/s |
| Load & Torque Capacity | Standard | High (Multiple teeth in mesh) | Very High (Extreme torque density) *¹ | High |
| Mechanical Efficiency | ~98% | ~97% | ~80% – 92% (Depends on offset) | ~97% |
| Shaft Offset Capability | No (90° Intersecting) | No (90° Intersecting) | Yes (Allows offset drive shafts) | No (90° Intersecting) |
| Lubrication Requirement | Standard grease / splash | Standard EP gear oil | Forced oil + EP additives required | Standard EP gear oil |
| Relative Cost & Lead Time | Lowest (Cost-effective) | Moderate | Higher (Complex machining & setup) | Moderate |
| Recommended Applications | Hand tools, low-speed reducers, agricultural machinery | Robotics, automation rotary tables, automotive differentials | Heavy-duty axle drives, conveyor systems, industrial gearboxes | High-speed aircraft drives, aerospace actuators, compact precision drives |
FAQ
Q: What is the minimum order quantity for custom bevel gears?
A: Our MOQ is 5 pieces. We also support prototype quantities for design validation - contact us to discuss your specific requirement.
Q: Do I need to provide a drawing to order?
A: A 2D or 3D drawing is preferred. If you can provide key parameters - module, number of teeth, bore diameter, tooth profile type, spiral direction, material, and precision grade - our engineers will generate a drawing for your review and approval before production begins.
Q: Can you achieve ISO Grade 5 precision for bevel gears?
A: Yes. For Grade 5 requirements, we apply CNC gear grinding after hobbing or skiving, with final CMM verification at ±0.01 mm. This level of precision is suitable for robotics joints, medical automation, servo-driven packaging lines, and similar high-demand applications.
Q: What is the typical lead time?
A: Custom bevel gear orders ship within 2–4 weeks, depending on geometry complexity, heat treatment, and order quantity. Contact us with your drawing for a specific lead time estimate.
Q: What tooth profiles do you support?
A: We manufacture straight bevel gears, spiral bevel gears (Gleason and non-Gleason), quasi-hypoid bevel gears, and Zerol bevel gears. If your application requires a non-standard profile, please share your drawing and we will advise on feasibility.
Q: Can you provide material certificates and inspection reports?
A: Yes. We provide dimensional inspection reports, material mill certificates, and hardness test records with every order. Third-party SGS inspection is also available on request.
