planetary gearbox NBR series
planetary gearbox NBR series
Overview of NBR Series Planetary Gearboxes
The NBR series planetary gearboxes are designed for optimized power transmission with features including low noise, improved precision, and high torsional torque capacity. The gearboxes incorporate helical and bevel gears, integrated planetary design, high precision bearings, and high-performance oil seals to enhance performance and durability.
Key Features and Benefits
- Optimized Power Transmission: Use of helical and bevel gears ensures efficient torque transfer with reduced noise and vibration.
- High Precision and Rigidity: High precision bearings and monoblock housing design contribute to ultimate tensile stiffness and torsional strength.
- Load Capacity: Designed to handle higher radial and axial loads with increased torsional torque.
- Efficiency and Durability: Lower friction leads to increased efficiency; IP protection level allows continuous operation up to high temperatures.
Technical Specifications
The gearboxes are available in multiple stages and sizes, with center distances and load points specified in millimeters. Key parameters include:
- Rated output torque (Nm)
- Backlash levels (ultraprecise, precise, standard)
- Efficiency (%)
- Service life (hours)
- Operating temperature range
- Noise level (dB(A)) at rated speed
- Lubrication: synthetic lubricant recommended
- Protection class: IP rated for harsh environments
Performance parameters such as maximum radial and axial forces, tilting moments, and rotary inertia are provided for different gearbox models and stages.
Design and Assembly
The NBR series features a monoblock housing and integrated planetary design for compactness and strength. The gearboxes come with options for output shafts including keyed (S2) and smooth (S1) shafts. Input end dimensions depend on the motor used, and detailed drawings are required for final confirmation.
When motor shaft diameters are small, shaft sleeves are necessary, and dimension reductions must be considered accordingly.
Installation and Operating Conditions
- Mounting position: any direction
- Continuous operation temperature up to specified limits (exact temperature not clearly legible)
- Noise levels measured at rated speed without load
- Use of synthetic lubricants recommended for optimal performance
Summary of Critical Parameters
| Parameter | Typical Range / Value |
|---|---|
| Rated Output Torque | Varies by model, up to several hundred Nm |
| Backlash | Ultraprecise to standard levels (exact arcmin values vary) |
| Efficiency | High efficiency due to low friction (exact % not specified) |
| Operating Temperature | Up to approximately 90°C (IP protection ensures continuous operation) |
| Noise Level | Low noise, measured in dB(A) at rated speed |
| Mounting | Any orientation |
Recommendations and Best Practices
- Confirm motor input dimensions with detailed drawings before assembly.
- Use shaft sleeves when motor shaft diameter is small to ensure proper fit and performance.
- Maintain lubrication with synthetic oils as specified to ensure longevity and efficiency.
- Consider load and torque limits carefully to avoid premature wear or failure.
Conclusion
The NBR series planetary gearboxes offer a robust solution for applications requiring high precision, rigidity, and torque capacity with optimized power transmission and low noise operation. Proper selection, installation, and maintenance are essential to maximize performance and service life.
