Robot 0° Spiral Gear Integrated Tooth-Shaft One-Piece Machining
This gear belongs to the Zerol Bevel Gear category and features an "integrated tooth-shaft" design. As a key precision component for robotic joint transmission, it can be introduced from the following aspects:
1. Structural & Design Highlights
▶0° Spiral Tooth Profile: The tooth line follows a spiral curve, yet the spiral angle at the
midpoint of the tooth width is 0°. It integrates the advantages of
straight bevel gears and spiral bevel gears.
▶Integrated Tooth-Shaft: The gear tooth and shaft are machined as a single piece,
eliminating fit clearance from traditional connections. This
significantly boosts transmission rigidity and precision, meeting
robotic joints’ demands for high responsiveness and no motion
backlash.
2. Process & Precision Features
▶Precision Grinding: Produced via CNC profile grinding machines, the tooth surface
achieves AGMA Class 12 precision, with meshing backlash controlled
within 5 μm. This ensures micron-level repeat positioning accuracy
for end effectors.
▶Heat Treatment: Teeth undergo carburizing, quenching, and low-temperature
tempering, reaching a surface hardness of HRC 58–62 while retaining
core toughness. This resists tooth wear and withstands impact
loads.
3. Robotic Scenario Adaptation
Different robot types demand unique "precision, load, and space"
tradeoffs, and this 0° spiral gear (integrated tooth-shaft type)
excels across scenarios:
| Robot Type | Key Requirements | Gear Advantages in This Scenario |
|---|---|---|
| Collaborative Robots | Low noise, compact structure | - Continuous meshing + no axial thrust → noise < 55 dB. |
| - No extra bearings → ultra-compact joints | ||
| Humanoid Robots | Lightweight, high rigidity | - Integrated design → 15% weight reduction vs. split structures. |
| - Spiral tooth geometry → 30% higher single-tooth load capacity. | ||
| Heavy-Duty Industrial Robots | High torque, long lifespan | - High tooth hardness + large contact ratio → withstands >200 N·m torque. |
| - Durability: >10,000 hours of heavy-load operation with minimal wear. |
4. Technological Trends
To align with robots’ "intelligent, maintenance-free" evolution, 0°
spiral gears are advancing in two directions:
▶Smart Sensing: Micro torque sensors are embedded in the shaft to
enable real-time load monitoring, powering robots’ force-control
algorithms.
▶Self-Lubrication: Tooth surfaces use diamond-like carbon (DLC)
coatings, slashing friction coefficients from 0.15 to 0.08 to
enable oil-free operation — ideal for medical robots.
In summary, the "0° spiral tooth + integrated tooth-shaft" design, via structural integration and advanced manufacturing, serves as a core transmission component for robotic joints — delivering high precision, rigidity, and scenario-specific adaptability, especially in space-constrained, high-response applications.
