- IP Protection: IP rating ensures continuous operation up to specified high temperatures.
- Integrated Planetary Design: Enhances torsional torque and power transmission efficiency.
- Low Noise Operation: Gear design and construction minimize operational noise.
- High Rigidity and Torque: Suitable for demanding precision applications.
3. Mechanical Specifications
The document provides detailed parameters including:
- Center Distance (X) and Load Point (Z): Critical dimensions for bearing load points and assembly.
- Torque Ratings: Rated output torque, maximum acceleration torque, and emergency stop torque values are specified.
- Speed Ratings: Rated input speed and maximum input speed are defined.
- Backlash Levels: Ultraprecise, precise, and standard backlash options are available to suit application needs.
- Load Capacities: Maximum radial and axial forces, as well as tilting moments, are provided.
- Service Life and Efficiency: Expected operational life and efficiency percentages are included.
- Operating Conditions: Temperature range, lubrication type (synthetic lubricant), and mounting positions are specified.
- Noise Level: Measured in dB(A) under no-load conditions at rated speeds.
- Weight and Rotary Inertia: Provided for various gearbox models and stages.
4. Assembly and Dimensional Notes
- Input end dimensions depend on the motor used; detailed drawings are required for final confirmation.
- When motor shaft diameters are small, shaft sleeves must be used, resulting in dimension reductions as indicated in the documentation.
- Output and input end dimensions vary by model and stage; specific values are provided for each gearbox variant.
5. Gear Types and Design
- Helical Gears: Used in certain NDR models to improve precision and reduce noise.
- Bevel Gears: Employed in other variants to increase torsional torque and optimize power transmission.
- Integrated Planetary Carriers: Enhance rigidity and torque transmission efficiency.
6. Protection and Lubrication
- IP Rating: The gearboxes have an IP protection level suitable for harsh environments and continuous operation.
- Lubrication: Synthetic lubricants are recommended to ensure longevity and performance.
