planetary gearbox NB series
planetary gearbox NB series
Overview of NB Series Planetary Gearboxes
The NB Series planetary gearboxes are designed for high precision, rigidity, and torque transmission. They feature an integrated planetary design with helical gears to optimize power transmission, reduce noise, and improve precision and torsional torque capacity.
Key Features
- High Precision Bearings: Enhance radial and axial load capacity.
- High Performance Oil Seal: Reduces friction, increasing efficiency.
- IP Protection Level: IP54 rating allows continuous operation up to 40°C.
- Optimized Power Transmission: Helical gear design for smooth and efficient torque transfer.
Performance Parameters
The gearboxes support continuous operation with synthetic lubrication and have the following critical parameters:
- Rated Output Torque (TN): Varies by model, with values provided in Nm.
- Max Acceleration Torque (TB): Defined for emergency stop conditions.
- Input Speed: Rated and maximum input speeds specified in rpm.
- Backlash: Available in ultraprecise, precise, and standard classes, measured in arcminutes.
- Radial and Axial Load Capacities: Maximum forces specified in Newtons.
- Tilting Moment: Defined for load handling.
- Service Life and Efficiency: Service life is guaranteed with high efficiency (η) values.
- Noise Level: Measured in dB(A) at 100 rpm without load.
- Operating Temperature Range: Typically -10°C to +40°C.
Design and Dimensions
The NB series offers multiple output shaft options, including keyed (S2) and smooth (S1) shafts. Dimensions vary by model and stage, with considerations for shaft sleeves when motor shaft diameters are small. Input end dimensions depend on the motor and require detailed drawings for confirmation.
- Dimension Reduction: When using shaft sleeves, specific dimension reductions apply, detailed per model.
- Mounting: Suitable for any mounting position.
Lubrication and Protection
- Lubrication: Synthetic lubricant recommended for continuous operation.
- Protection Class: IP54 ensures protection against dust and splashing water.
Recommendations and Best Practices
- Ensure motor shaft dimensions are compatible or use shaft sleeves with appropriate dimension adjustments.
- Confirm input end dimensions with detailed motor drawings before final assembly.
- Operate within specified temperature and load limits to maintain performance and service life.
- Choose backlash class according to precision requirements.
Summary
The NB Series planetary gearboxes provide a robust solution for applications requiring high precision, torque, and reliability. Their design emphasizes low noise, high efficiency, and adaptability to various motor configurations, making them suitable for demanding industrial uses.
