planetary gearbox NFR series
Overview of NFR Series Precision Planetary Gearboxes
The NFR series offers high precision planetary gearboxes designed for high rigidity and torque transmission. These gearboxes incorporate advanced features such as helical and bevel gears, integrated planetary design, and high precision bearings to ensure superior performance.
Key Features
- High Precision Bearings: Provide enhanced radial and axial load capacity, improving durability and reliability.
- High Performance Oil Seal: Reduces friction, increasing efficiency and operational lifespan.
- IP Protection Level: IP54 rating ensures continuous operation in various environments up to 40°C.
- Optimized Power Transmission: Helical and bevel gears reduce noise and improve precision and torsional torque.
- Low Noise Operation: Designed to minimize operational noise for sensitive applications.
Performance Parameters
The gearboxes are characterized by several critical parameters:
- Rated Output Torque (TN): Defined for each model, ensuring suitability for various load requirements.
- Max Acceleration Torque (TB): Indicates the maximum torque during acceleration phases.
- Emergency Stop Torque (TNOT): Maximum torque during emergency stops.
- Input Speeds: Rated input speed (nN) and maximum input speed (nB) are specified.
- Backlash: Available in ultraprecise, precise, and standard levels to suit different precision needs.
- Radial and Axial Forces (FrB, FaB): Maximum forces applied at the output shaft center at 100 rpm.
- Tilting Moment: Maximum permissible tilting moment on the output shaft.
- Service Life and Efficiency (η): High service life with efficiency values provided for each model.
- Operating Temperature Range: Typically -10°C to 40°C for continuous operation.
- Lubrication: Synthetic lubricant recommended for optimal performance.
- Noise Level: Measured in dB(A) at rated speed without load.
- Rotary Inertia: Provided for dynamic analysis.
Mechanical Design and Dimensions
The NFR series gearboxes feature multiple output shaft options:
- S2 Keyed Shaft Output and S1 Smooth Shaft Output with dimensions varying by model and stage.
- Input End Dimensions: Determined by the motor; detailed drawings are required for final confirmation.
- Shaft Sleeve Usage: When motor shaft diameter is small, a shaft sleeve is necessary, which reduces dimensions as indicated.
Dimension reductions with shaft sleeves are specified for each model and stage, ensuring compatibility with various motor configurations.
Recommendations and Best Practices
- Confirm motor shaft dimensions and provide detailed drawings before finalizing gearbox integration.
- Use synthetic lubricants as specified to maintain performance and longevity.
- Consider the IP54 protection level for environmental suitability.
- Account for dimension reductions when using shaft sleeves to ensure proper fit.
- Select appropriate backlash level based on precision requirements.
Summary
The NFR series planetary gearboxes are engineered for applications requiring high precision, rigidity, and torque capacity. Their design incorporates advanced gearing, sealing, and bearing technologies to optimize power transmission, reduce noise, and extend service life. Proper selection and integration considering motor compatibility and operational parameters will ensure optimal performance.
