Newstart Humanoid Robot Joint Reducer Catalog
1. Product Description and Design Features
The NEWSTART NT and NTAD series joint reducers are engineered specifically for humanoid robot joints. They feature a compact footprint, high load-bearing capacity, efficient transmission, durability, and cost-effectiveness, making them ideal for robotic applications requiring precise and reliable motion control.
2. Technical Specifications
The document details extensive technical parameters across multiple models and variants, including:
- Reduction Ratios: Wide range from 5:1 up to 95:1 and beyond, allowing customization for various torque and speed needs.
- Load Capacities: Radial loads from 150 N to 3490 N; axial loads up to 2430 N depending on model.
- Torque Ratings: Nominal output torque ranges between 7.5 Nm and 300 Nm; maximum acceleration and sudden stop torques can significantly exceed nominal values.
- Operating Conditions: Temperature range typically -15°C to +90°C, with some models rated up to 200°C for acceleration torque.
- Input Speeds: Nominal speeds generally 2000-3000 rpm; maximum speeds up to 6000 rpm with synthetic grease lubrication.
- Protection and Noise: IP54 protection ensures dust and splash resistance; noise levels maintained below 68 dB(A).
- Backlash and Shaft Locking: Backlash controlled between ≤5 to ≤25 arcmin; input shaft locking torque varies from 1 Nm to ~120 Nm.
- Service Life: Rated for at least 20,000 hours under normal operating conditions.
3. Lubrication and Maintenance
All models utilize synthetic grease lubrication, supporting high-speed operation and ensuring longevity. Regular lubricant replacement and proper lubrication practices are emphasized to maintain performance and reduce noise.
4. Model Variants and Dimensions
The document lists multiple model variants (e.g., NTAD64L1, NTAD90L2, NTAD110L2) with detailed dimensional data, motor shaft hole sizes, and flange mounting specifications to ensure compatibility and ease of integration into robotic systems.
5. Performance and Application Recommendations
- Recommended reduction ratios and load limits are provided to optimize performance and extend service life.
- Sudden stop and maximum acceleration torque values guide safe operational limits to prevent damage.
- Operating temperature guidelines ensure reliable function within environmental constraints.
6. Protection and Durability
- IP54 rating guarantees protection against dust ingress and water splashes.
- High durability with service life exceeding 20,000 hours under normal use.
7. Fault Diagnosis and Troubleshooting
The document includes a comprehensive troubleshooting guide addressing common issues such as:
- Oil Leakage: Caused by seal wear, installation errors, or lubricant misapplication; solutions include seal replacement and proper lubricant control.
- Abnormal Noise: Often due to poor lubrication, contamination, motor misalignment, or overload; resolved by cleaning, lubrication, and correct assembly.
- Overheating: Linked to insufficient lubrication or heat dissipation; improved cooling and lubrication recommended.
- Gear Wear/Damage: Requires inspection and replacement of worn components.
- Torque Instability: Due to gear misalignment or shaft issues; corrected by adjustment or shaft replacement.
- Excessive Backlash: Caused by bearing wear or improper installation; addressed by bearing replacement and recalibration.
- Transmission Efficiency Decline: From poor lubrication or internal friction; improved lubrication and component checks advised.
- Output Shaft Breakage: Resulting from overload or material defects; avoid overload and conduct regular inspections.
8. Recommendations and Best Practices
- Use high-quality materials and proper heat treatment to prevent gear failure.
- Maintain cleanliness to avoid contamination and foreign body ingress.
- Regularly replace lubricants to sustain optimal performance.
- Ensure precise installation and calibration to maintain reduction accuracy and minimize backlash.
- Avoid overload conditions to extend service life and prevent mechanical damage.
